I noticed that there was a thread about countering bird offense, but not one about the birds themselves. Feel free to suggest changes to the OP!
The Flying typing is often looked down largely for its weakness to Stealth Rock, as well as the other typing weaknesses that often follow. However, NU is one tier where Flying types can really shine. Throughout the entire tier, these Pokemon fulfill a wide range of roles and unique niches, from fierce sweepers to wall breakers, and from supporters to stalling machines. So let's look into the Flying types of NU!
The Birds…
100 / 123 / 75 / 57 / 75 / 80
When you think bird offense, chances are you'll think of Braviary. Braviary is one of the most offensively impressive birds in the tier. While a base 80 speed isn't something to write home about, that impressive base 123 Atk stat is very powerful, especially when backed by powerful STABs like Brave Bird and Return. However, one of Braviary's greatest assets is its unique method of getting past the powerful Rock and Steel types that often plague Flying types: Superpower. This allows Braviary to put huge dents in Pokemon like Golem and Regirock, if not outright killing them. The war-eagle also has a few other assets that make it an attractive choice. U-turn is always useful for maintaining momentum and allowing Braviary to switch with a partner who can better handle an incoming threat. Sheer Force also allows Braviary to use Rock Slide as a coverage move, giving it the equivalent of a more accurate Stone Edge. 100/75/75 defenses also provide reasonable bulk, allowing Braviary to take a hit when needed. In short, underestimate Braviary at your own risk.
60 / 85 / 60 / 50 / 50 / 125
At first glance, Swellow doesn't look like much. Base 125 speed is great, but a base 85 Atk stat is fairly average, and Swellow's 60/60/50 defenses are just adorable. However, its true strengths can only be realized once it has activated its ability: Guts. Not only does this give Swellow an impressive boost to its power overall, but it also gives the Swallow Pokemon a 140 power STAB in Façade. Combined with Brave Bird and its incredible speed, this allows Swellow to become one of the fiercest offensive bird out there. When the going gets tough, Swellow can just U-turn out to an appropriate counter as well. Swellow will always be waiting, ready to decimate the opponent's team once the bulky Rock and Steel types are gone.
75 / 70 / 90 / 70 / 105 / 80
Altaria sets itself apart from other NU birds via its Dragon typing; the only fully evolved Dragon in NU, as a matter of fact. It's average 70/70/80 offenses soon become quite threatening when backed by Dragon Dance and Altaria's great offensive movepool. Not only that, but Altaria has impressive bulk and a great support movepool. This allows it to function not only as an offensive or bulky sweeper, but also as a support platform with moves such as Heal Bell, Roar, Haze, and Perish Song, as well as reliable recovery in Roost. All of this combined makes Altaria one of the most feared Pokemon in all of NU.
60 / 110 / 70 / 60 / 60 / 100
At first, Dodrio looks like it would be a prime Flying type with is impressive 110/100 offenses and poweful STAB moves. However, the main thing that holds it back is its lack of coverage in its movepool. This leaves Dodrio helpless before bulky Rock and Steel types, without even U-turn to escape with. However, Dodrio does have some assets to set itself apart. Although it may look weaker and slower than Guts Swellow, its lack of reliance on Guts allows it to run an impressive Choice Band or Scarf set. Even with an Adamant nature, Dodrio is able to outspeed most of the Pokemon in NU with a Scarf, giving it an impressive combination of power and speed. Don't be fooled by its shallow movepool; Dodrio is a true offensive powerhouse.
65 / 90 / 65 / 61 / 61 / 100
One look and you'll think that Fearow is just a poor man's Dodrio; same speed with less power. To make matters worse, Fearow doesn't even get Brave Bird! However, the sweet part is that Fearow has a new move that Dodrio wishes it had: Drill Run. This gives Fearow a new coverage move that allows it to considerable damage against the Pokemon that would otherwise tank it with ease. Besides this, it still has good 90/100 offenses, allowing Fearow to be an offensive threat when needed.
90 / 85 / 100 / 95 / 125 / 85
On paper, Articuno looks phenomenal. 90/100/125 defenses are fantastic, and 85/95/85 offenses aren't too shabby either. The problem lies not with Articuno's stats, but its typing. Ice/Flying gives Articuno a myriad of weaknesses, including a crippling Rock weakness that leaves it half-dead after switching into Stealth Rock. Don't be too dismayed, since Articuno's good qualities still allow it to perform admirably. Articuno's good speed combined with its excellent bulk makes it a fantastic user of the infamous SubRoost set. The icy bird can also support its team well with its many support options, and it can do decent damage to opposing Pokemon with a STAB Ice Beam. Just pack a Rapid Spinner and you'll be set!
60 / 85 / 42 / 85 / 42 / 91
Murkrow looks like it would be a decent offensive Pokemon when you look at it from the surface. Good offenses and a movepool with options like Heat Wave, Brave Bird, and Sucker Punch help with such a role. However, Murkrow's true niche lies in its new Dream World ability: Prankster. With priority on nearly everything, Murkrow can function as a great support Pokemon, assisting its team by crippling or killing opposing Pokemon with options like Mean Look + Perish Song and Feather Dance, as well as having priority Roost, Substitute, and Taunt to stall on its own. The Evolite also boosts Murkrow's otherwise pitiful defenses to more acceptable levels, further boosting its survivability.
75 / 87 / 63 / 87 / 62 / 98
Swanna has a niche as an offensive Water/Flying type because of its access to the elusive Hurricane, making it a great sweeper in the Rain. Between Hurricane and Surf, Swanna can tackle a large number of Pokemon with that excellent coverage. It's stats don't let it down either, with a nice base 87 SpA and Atk and an exceptional base 98 speed. Swanna also has the ability to get past Pokemon that would usually wall it, such as Jynx and Cryogonal, by exploiting their lower Def stat with its powerful Brave Bird attack. Once its Dream World ability is released, Swanna will have an additional niche as an offensive Hydration abuser. Overall, Swanna makes for an impressive Rain attacker that just likes hitting stuff hard.
60 / 50 / 100 / 85 / 70 / 65
Pelipper performs similarly to Swanna as a Rain attacker, only with a little more physical bulk and less speed. However, Pelipper does have a little something to set itself apart. Access to Hydro Pump provides it with a more powerful Water STAB than its swan cousin. Rain Dish also allows it to more successfully abuse Rain (until Hydration Swanna is released, that is), giving Pelipper more survivability in the Rain. Despite its cousin's greater overall offensive stats, Pelipper definitely has a little something to set itself apart.
40 / 50 / 45 / 70 / 45 / 70
Natu doesn't look like much at all on paper. While base 70 speed is alright for a support Pokemon, its offenses are pitiful and its defenses are pretty thin, even when boosted by the Evolite. However, Natu's Dream World ability, Magic Bounce, gives it plenty of a reason to be used in NU. As the only Magic Bounce user in NU, Natu finds an excellent niche in blocking entry hazards, status moves, Taunt, or any other non-damaging attacks that may threaten its teammates. Natu can still survive some weaker attacks with investment, and U-turn is a great momentum keeper and a saving grace for when Natu is in trouble, making the little birdie a great supporter indeed.
83 / 80 / 75 / 70 / 70 / 91
Pidgeot is, sadly, one of the lesser birds. It really doesn't have much to call its own apart from the other birds. It does have a little extra bulk than some of the other birds, and a nice base 91 speed, but not much else. What Pidgeot does have, however, is a unique movepool consisting of moves such as Heat Wave and Hurricane. While a base 70 SpA isn't much, it's enough to give Pidgeot use of those moves, as well as its already powerful options like Brave Bird and Return. Overall, though, there isn't too much of a reason to use Pidgeot over rivaling birds.
80 / 105 / 80 / 65 / 55 / 93
A great combination of Atk and speed would make Unfezant look like a nice physical attacker, but sadly that's not the case. Unlike most other NU birds, it doesn't have access to Brave Bird or even Drill Peck. What it does have, however, is a collection of unique support options. Hypnosis and Taunt are two such options that Unfezant is able to use to some success. Its aforementioned offenses also allow it to not be a sitting duck on the battlefield, having a little offensive potential with a powerful STAB Return. Still, if you're not using Unfezant for these unique qualities, you probably shouldn't be using it at all.
100 / 50 / 50 / 76 / 96 / 70
Noctowl looks like a defensive bird by its stats, and you'd be right to say so. Noctowl's main niche as a Flying type comes from its good defenses (mainly on the special side) and its great support options. Moves like Whirlwind, Roost, Hypnosis, Magic Coat, and Dual Screens provides Noctowl with a boatload of options to support its team with. It also has the ability to bypass its low offenses with Night Shade, causing constant damage with each hit. Just keep a lookout for strong super-effective attacks, and Noctowl will gladly provide the support your team needs.
76 / 65 / 45 / 92 / 42 / 91
Chatot is a funny little bird, and I don't mean just because it's a parrot. Unlike most of the other birds (besides Swanna and Pelipper), Chatot sets itself apart as a special attacker. This is backed up not only by its good combination of speed and SpA, but also by its access to Nasty Plot, boosting its SpA to great levels after just one turn. Its movepool is unfortunately lacking, but it does have a nice STAB move in Hyper Voice and decent coverage between Heat Wave and Hidden Power. Chatot also has access to Encore, allowing it to find good opportunities to set up on an opponent trapped into a useless move. This helps to bypass its terrible defenses, which would otherwise not give it much wiggle room.
52 / 65 / 55 / 58 / 62 / 60
Farfetch'd is a joke, might as well admit it. All of its stats are low, and it's terribly outclassed at nearly everything. Still, for such a pitiful Pokemon, it has the potential to do…something. After a Swords Dance, Adamant Farfetch'd is hitting nearly as hard as Jolly CB Braviary, which isn't too bad. It also gets the classic Brave Bird/Return combo, as well as Revenge to give the little duck a weapon against Rock and Steel types. Still, even with that decent power and coverage, it really doesn't have the speed or bulk to do anything resembling a sweep.
45 / 55 / 45 / 65 / 45 / 75
And if you thought Farfetch'd was bad, meet Delibird. Not only are its stats poor, its typing does it no favors either. It's not so much that Delibird is incapable of doing damage. With Hustle and a Choice Band, Delibird is hitting with decent power. It also has access to Ice Shard and the powerful Focus Punch, very good options. However, its other STABs are weak, and the little Santa bird will most likely die in one hit. At least it has Rapid Spin…yeah, unless it's December, don't use Delibird.
…the Bees...
61 / 90 / 45 / 50 / 50 / 160
Although the fall to NU is drastic, Ninjask pretty much picks up where it left off in 4th Gen; Baton Passing Speed Boosts and Swords Dances. Ninjask is infamous for setting up a Swords Dance, using Substitute and Protect to stall a few turns for Speed Boosts, and then Baton Passing those boosts (and if it's lucky, a Substitute) to an ally who needs it. It can also do a little damage with X-Scissor coming of its decent base 90 Atk, and…well, that's just about it. Ninjask is a one trick pony, but it's pretty good at what it does.
60 / 45 / 50 / 80 / 80 / 70
Butterfree doesn't look like much at all based on its stats and typing alone. It's claim to fame, however, comes in two forms. First is its access to Compoundeyes, improving the accuracy of Sleep Powder (and to a lesser extent, Stun Spore) to near perfect levels. The second is the new boosting move: Quiver Dance. This allows Butterfree to quickly become an offensive threat, while also making Butterfree a special tank of sorts. This combination of Sleep Powder and Quiver Dance is what makes Butterfree a very real threat. The butterfly can even forgo Compoundeyes for Tinted Lens, sacrificing some accuracy for a nearly unresisted Bug Buzz, further improving its offensive potential.
70 / 60 / 62 / 80 / 82 / 60
Masquerain may seem like just another Quiver Dancer at first, but it definitely has some edges over the others. First is its Intimidate ability, which allows Masquerain to better handle physical attacks while Quiver Dance boosts its tolerance for special hits. Secondly, Masquerain has a few impressive move options, such as Hydro Pump and Ice Beam. Finally, Masquerain is one of the few Pokemon capable of Baton Passing Quiver Dance. This alone gives this guy an edge over the competition, allowing it to either use the Quiver Dance boosts to sweep on its own or to pass them off to an even more powerful teammate.
70 / 94 / 50 / 94 / 50 / 66
Of all of the Quiver Dancers in NU, Mothim is the most powerful. Base 94 SpA is impressive, especially after boosted once or twice by Quiver Dance. What makes Mothim even more of an offensive threat is its access to Tinted Lens, giving it nearly unresisted coverage with its Bug STAB alone. Access to STAB Air Slash, complimented by the appropriate Hidden Power, gives Mothim even more coverage and an even greater chance to sweep. Unfortunately, the moth is still held back by its sub-par speed and frail defenses. Still, Mothim's power and coverage with Tinted Lens are reason enough to use it over the competition.
60 / 70 / 50 / 90 / 50 / 65
Beautifly looks strikingly similar to Mothim on the surface. Very similar stats (besides Mothim's greater Atk), similar movepools, access to Quiver Dance…overall, Beautifly is mostly outclassed by Mothim. Still, it isn't too bad on its own. The butterfly still has plenty of power, more so than Butterfree or Masquarain, and can be an offensive threat after Quiver Dance and its good coverage moves. It also has Stun Spore to set itself apart from Mothim. Still, between the two, I'd have to pick Mothim nearly every time.
70 / 80 / 102 / 80 / 102 / 40
Vespiquen's stats just scream "defensive Pokemon." Vespiquen is without a doubt the bulkiest Bug type in all of NU, and it does have a few assets to take advantage of that. Like Articuno, Vespiquen can use SubRoost, Toxic, and Pressure to wear opponents down and run the PP out of their coverage moves. Vespiquen also has a decent base 80 Atk stat and a good STAB move in Attack Order to prevent it from being a sitting duck. Still, that Bug/Flying typing really hurts it, and there's really not much it can do past SubRoost.
50 / 35 / 50 / 55 / 110 / 85
I'll be honest, I only included Ledian because not doing so would be rude. Even as far as some Pokemon go, Ledian is pathetic. The ladybug has terrible offenses, and its great SpD is destroyed by its low HP. It has decent speed and a good support movepool, but even then most of what it does is badly outclassed. It can Baton Pass Agilities and Swords Dances, but besides the useful utility of Encore, why do that when Ninjask is available? It can set up Screens too, but there are plenty of Pokemon who can do that far better. If only it had better offenses to take advantage of its good offensive movepool, boasting options like Mach Punch and Bug Buzz, but the sad fact is it doesn't. Just…don't use Ledian.
…and the Other Things
50 / 65 / 107 / 105 / 107 / 86
Rotom-S made a big splash in the NU metagame as the tier was forming. While its new typing may have left it outclassed by the other forms in the upper tiers (and some other Pokemon as well), it gave Rotom-S a new niche in NU. Even with that low base 50 HP, Rotom-S is still pretty bulky. It's great base 105 SpA and good base 86 speed also give it plenty of potential as an offensive beast. Its particular speed stat also allows it to check Pokemon like Scarf Sawk and Shell Smash Gorebyss with ease, and its new toy in Volt Switch gives it a great momentum-winning tool. Don't let the redundancy of its typing and ability fool you. Rotom-S is one of the most fearsome Pokemon in the metagame.
75 / 80 / 70 / 65 / 75 / 90
Golbat gained a new niche on the competitive scene with the Evolite, giving it the equivalent of 75/130/137 base defenses. With this impressive bulk, as well as its great typing that gives it a 4x resistance to Fighting, Bug, and Grass moves, Golbat finds its place as a fantastic defensive Pokemon. Base 90 speed is also pretty fast for a defensive threat, allowing Golbat to stall break effectively with Taunt. Super Fang is another neat option for breaking down walls, and Roost is the same reliable healing move it's always been. Golbat doesn't entirely fear opposing Taunts either, since its decent base 80 Atk stat makes Brave Bird a fearsome weapon. It does have some common weaknesses, but it can easily overcome these with a little support.
150 / 80 / 44 / 90 / 54 / 80
Drifblim is a weird Pokemon. It doesn't look like the kind of Pokemon to be sweeping, but it's perfectly capable of it. Despite its terrible defenses, it still maintains good bulk with its amazing HP stat. 90/80 offenses also make Drifblim into a nice special attacker. What really makes Drifblim shine, though, is Unburden. With Unburden, Drifblim can run an interesting ChestoRest set, setting up Calm Mind, Resting when needed, nabbing the Unburden speed boost, and then sweeping with the combination of Shadow Ball and a coverage move. Drifblim can also make an interesting Baton Passer, getting defensive boosts with Stockpile, enabling it to pass off those boosts and a very sturdy Substitute.
75 / 55 / 70 / 55 / 85 / 110
Jumpluff isn't really much for offense, and…it's not too much for defense either. At least, that's the way it looks on paper. However, with that impressive base 110 speed, Jumpluff becomes a very fast and successful SubSeeder. SubSeed Jumpluff isn't a one-man show; it might need some Toxic/Toxic Spikes support to increase its effectiveness. However, once set up, Jumpluff can stall for ages between Leech Seed and Substitute. Jumpluff is also set apart by its access to a very fast Sleep Powder and Encore, giving it some assets that many other SubSeeders don't have. Jumpluff can also be a good Sun supporter, and it has Memento to assist a partner's setup once its job is done.
65 / 40 / 70 / 80 / 140 / 70
Stat-wise, Mantine is the special version of Skarmory. Although it sounds like that would make Mantine a top-notch special wall, it sadly doesn't. Mantine lacks access to Roost, leaving it with only Rest for recovery. Still, Mantine does have its perks. Scald, Mantine's newest option, gives it the ability to threaten physical attackers with burns, allowing it to survive on both the physical and special side very well. It also has Water Absorb, making it a prime switch-in to many different Water types, especially since many of those Water types carry HP Grass over HP Electric for Quagsire. Even with the new sleep mechanics, RestTalk isn't too bad, healing all of Mantine's health while also healing off status.
55 / 40 / 85 / 80 / 105 / 40
Togetic has a newfound niche with the Evolite, giving it the equivalent of 55/152/182 defenses. That's bulky. I mean really bulky. Also, unlike many bulky Pokemon, Togetic has excellent reliable recovery in Roost. Togetic doesn't just sit there and look good, though. It has a pretty nice support movepool, boasting options like Thunder Wave, Heal Bell, Toxic, Encore, and Baton Pass. Togetic also has a decent base 80 SpA stat, giving it the ability to cause a little damage with Tri-Attack, which has a 40% chance to cause either a burn, paralysis, or freezing with Serene Grace. Underestimate this little fairy at your own peril; it won't go down easily.
67 / 57 / 55 / 77 / 55 / 114
Swoobat is just one of those Pokemon that can't wait for its Dream World ability to be released, in this case so it can start abusing Simple + Calm Mind. What it has now is Unaware combined with a base 114 speed stat, making it by far the fastest user of Unaware out there. It's also the fastest Dual Screen user in NU, and it has a few other useful support options to help with that role. Offensively, its good speed and passable SpA makes it a decent Calm Mind user. Unaware also means that Swoobat will be able to win Calm Mind wars more easily. Overall, though, Calm Mind Swoobat will be much better when Simple is released, giving it massive boosts after just two turns, as well as a very powerful Stored Power.
99 / 68 / 83 / 72 / 87 / 51
Tropius has a few interesting options that really set it apart as a Flying type. The most notable is Harvest, an ability unique to a small handful of Pokemon. With this ability, Tropius becomes a new kind of SubSeeder, using a limitless Sitrus Berry as its HP gets a little lower. This compiled with Tropius's great bulk makes it an excellent SubSeeder. It even gets Air Slash to punish those Grass types that are immune to Leech Seed. Tropius can also sweep with Chlorophyll, Growth, and its decent offensive movepool. Too bad Leaf Blade is illegal with Dragon Dance, or else Tropius would have that as an option as well.
55 / 75 / 60 / 75 / 60 / 103
Yeah, and you thought Garchomp's speed stat was trollish. Besides that great speed stat, however, Emolga doesn't have too much to its name. It can be a decent Agility Baton Passer, but Ninjask Baton Passes the speed boosts so much easier. Emolga does have a few neat options, such as Encore, which gives it a little something. Electric/Flying typing is pretty nice, too, and Emolga is capable of doing some damage with good offensive options on both sides of the spectrum. A fast Volt Switch is a neat tool as well. Emolga may not be the most powerful or bulkiest thing around, but it's got a little something to help it shine.
So there you have it. As you can see, there are a ton of Flying types that occupy NU, taking a variety of roles and niches. Each one has something special about it, making Flying types one of the most diverse and successful groups of Pokemon in the NU tier. So let's talk Flying types!
The Flying typing is often looked down largely for its weakness to Stealth Rock, as well as the other typing weaknesses that often follow. However, NU is one tier where Flying types can really shine. Throughout the entire tier, these Pokemon fulfill a wide range of roles and unique niches, from fierce sweepers to wall breakers, and from supporters to stalling machines. So let's look into the Flying types of NU!
The Birds…
100 / 123 / 75 / 57 / 75 / 80
When you think bird offense, chances are you'll think of Braviary. Braviary is one of the most offensively impressive birds in the tier. While a base 80 speed isn't something to write home about, that impressive base 123 Atk stat is very powerful, especially when backed by powerful STABs like Brave Bird and Return. However, one of Braviary's greatest assets is its unique method of getting past the powerful Rock and Steel types that often plague Flying types: Superpower. This allows Braviary to put huge dents in Pokemon like Golem and Regirock, if not outright killing them. The war-eagle also has a few other assets that make it an attractive choice. U-turn is always useful for maintaining momentum and allowing Braviary to switch with a partner who can better handle an incoming threat. Sheer Force also allows Braviary to use Rock Slide as a coverage move, giving it the equivalent of a more accurate Stone Edge. 100/75/75 defenses also provide reasonable bulk, allowing Braviary to take a hit when needed. In short, underestimate Braviary at your own risk.
60 / 85 / 60 / 50 / 50 / 125
At first glance, Swellow doesn't look like much. Base 125 speed is great, but a base 85 Atk stat is fairly average, and Swellow's 60/60/50 defenses are just adorable. However, its true strengths can only be realized once it has activated its ability: Guts. Not only does this give Swellow an impressive boost to its power overall, but it also gives the Swallow Pokemon a 140 power STAB in Façade. Combined with Brave Bird and its incredible speed, this allows Swellow to become one of the fiercest offensive bird out there. When the going gets tough, Swellow can just U-turn out to an appropriate counter as well. Swellow will always be waiting, ready to decimate the opponent's team once the bulky Rock and Steel types are gone.
75 / 70 / 90 / 70 / 105 / 80
Altaria sets itself apart from other NU birds via its Dragon typing; the only fully evolved Dragon in NU, as a matter of fact. It's average 70/70/80 offenses soon become quite threatening when backed by Dragon Dance and Altaria's great offensive movepool. Not only that, but Altaria has impressive bulk and a great support movepool. This allows it to function not only as an offensive or bulky sweeper, but also as a support platform with moves such as Heal Bell, Roar, Haze, and Perish Song, as well as reliable recovery in Roost. All of this combined makes Altaria one of the most feared Pokemon in all of NU.
60 / 110 / 70 / 60 / 60 / 100
At first, Dodrio looks like it would be a prime Flying type with is impressive 110/100 offenses and poweful STAB moves. However, the main thing that holds it back is its lack of coverage in its movepool. This leaves Dodrio helpless before bulky Rock and Steel types, without even U-turn to escape with. However, Dodrio does have some assets to set itself apart. Although it may look weaker and slower than Guts Swellow, its lack of reliance on Guts allows it to run an impressive Choice Band or Scarf set. Even with an Adamant nature, Dodrio is able to outspeed most of the Pokemon in NU with a Scarf, giving it an impressive combination of power and speed. Don't be fooled by its shallow movepool; Dodrio is a true offensive powerhouse.
65 / 90 / 65 / 61 / 61 / 100
One look and you'll think that Fearow is just a poor man's Dodrio; same speed with less power. To make matters worse, Fearow doesn't even get Brave Bird! However, the sweet part is that Fearow has a new move that Dodrio wishes it had: Drill Run. This gives Fearow a new coverage move that allows it to considerable damage against the Pokemon that would otherwise tank it with ease. Besides this, it still has good 90/100 offenses, allowing Fearow to be an offensive threat when needed.
90 / 85 / 100 / 95 / 125 / 85
On paper, Articuno looks phenomenal. 90/100/125 defenses are fantastic, and 85/95/85 offenses aren't too shabby either. The problem lies not with Articuno's stats, but its typing. Ice/Flying gives Articuno a myriad of weaknesses, including a crippling Rock weakness that leaves it half-dead after switching into Stealth Rock. Don't be too dismayed, since Articuno's good qualities still allow it to perform admirably. Articuno's good speed combined with its excellent bulk makes it a fantastic user of the infamous SubRoost set. The icy bird can also support its team well with its many support options, and it can do decent damage to opposing Pokemon with a STAB Ice Beam. Just pack a Rapid Spinner and you'll be set!
60 / 85 / 42 / 85 / 42 / 91
Murkrow looks like it would be a decent offensive Pokemon when you look at it from the surface. Good offenses and a movepool with options like Heat Wave, Brave Bird, and Sucker Punch help with such a role. However, Murkrow's true niche lies in its new Dream World ability: Prankster. With priority on nearly everything, Murkrow can function as a great support Pokemon, assisting its team by crippling or killing opposing Pokemon with options like Mean Look + Perish Song and Feather Dance, as well as having priority Roost, Substitute, and Taunt to stall on its own. The Evolite also boosts Murkrow's otherwise pitiful defenses to more acceptable levels, further boosting its survivability.
75 / 87 / 63 / 87 / 62 / 98
Swanna has a niche as an offensive Water/Flying type because of its access to the elusive Hurricane, making it a great sweeper in the Rain. Between Hurricane and Surf, Swanna can tackle a large number of Pokemon with that excellent coverage. It's stats don't let it down either, with a nice base 87 SpA and Atk and an exceptional base 98 speed. Swanna also has the ability to get past Pokemon that would usually wall it, such as Jynx and Cryogonal, by exploiting their lower Def stat with its powerful Brave Bird attack. Once its Dream World ability is released, Swanna will have an additional niche as an offensive Hydration abuser. Overall, Swanna makes for an impressive Rain attacker that just likes hitting stuff hard.
60 / 50 / 100 / 85 / 70 / 65
Pelipper performs similarly to Swanna as a Rain attacker, only with a little more physical bulk and less speed. However, Pelipper does have a little something to set itself apart. Access to Hydro Pump provides it with a more powerful Water STAB than its swan cousin. Rain Dish also allows it to more successfully abuse Rain (until Hydration Swanna is released, that is), giving Pelipper more survivability in the Rain. Despite its cousin's greater overall offensive stats, Pelipper definitely has a little something to set itself apart.
40 / 50 / 45 / 70 / 45 / 70
Natu doesn't look like much at all on paper. While base 70 speed is alright for a support Pokemon, its offenses are pitiful and its defenses are pretty thin, even when boosted by the Evolite. However, Natu's Dream World ability, Magic Bounce, gives it plenty of a reason to be used in NU. As the only Magic Bounce user in NU, Natu finds an excellent niche in blocking entry hazards, status moves, Taunt, or any other non-damaging attacks that may threaten its teammates. Natu can still survive some weaker attacks with investment, and U-turn is a great momentum keeper and a saving grace for when Natu is in trouble, making the little birdie a great supporter indeed.

Pidgeot is, sadly, one of the lesser birds. It really doesn't have much to call its own apart from the other birds. It does have a little extra bulk than some of the other birds, and a nice base 91 speed, but not much else. What Pidgeot does have, however, is a unique movepool consisting of moves such as Heat Wave and Hurricane. While a base 70 SpA isn't much, it's enough to give Pidgeot use of those moves, as well as its already powerful options like Brave Bird and Return. Overall, though, there isn't too much of a reason to use Pidgeot over rivaling birds.
80 / 105 / 80 / 65 / 55 / 93
A great combination of Atk and speed would make Unfezant look like a nice physical attacker, but sadly that's not the case. Unlike most other NU birds, it doesn't have access to Brave Bird or even Drill Peck. What it does have, however, is a collection of unique support options. Hypnosis and Taunt are two such options that Unfezant is able to use to some success. Its aforementioned offenses also allow it to not be a sitting duck on the battlefield, having a little offensive potential with a powerful STAB Return. Still, if you're not using Unfezant for these unique qualities, you probably shouldn't be using it at all.
100 / 50 / 50 / 76 / 96 / 70
Noctowl looks like a defensive bird by its stats, and you'd be right to say so. Noctowl's main niche as a Flying type comes from its good defenses (mainly on the special side) and its great support options. Moves like Whirlwind, Roost, Hypnosis, Magic Coat, and Dual Screens provides Noctowl with a boatload of options to support its team with. It also has the ability to bypass its low offenses with Night Shade, causing constant damage with each hit. Just keep a lookout for strong super-effective attacks, and Noctowl will gladly provide the support your team needs.
76 / 65 / 45 / 92 / 42 / 91
Chatot is a funny little bird, and I don't mean just because it's a parrot. Unlike most of the other birds (besides Swanna and Pelipper), Chatot sets itself apart as a special attacker. This is backed up not only by its good combination of speed and SpA, but also by its access to Nasty Plot, boosting its SpA to great levels after just one turn. Its movepool is unfortunately lacking, but it does have a nice STAB move in Hyper Voice and decent coverage between Heat Wave and Hidden Power. Chatot also has access to Encore, allowing it to find good opportunities to set up on an opponent trapped into a useless move. This helps to bypass its terrible defenses, which would otherwise not give it much wiggle room.
52 / 65 / 55 / 58 / 62 / 60
Farfetch'd is a joke, might as well admit it. All of its stats are low, and it's terribly outclassed at nearly everything. Still, for such a pitiful Pokemon, it has the potential to do…something. After a Swords Dance, Adamant Farfetch'd is hitting nearly as hard as Jolly CB Braviary, which isn't too bad. It also gets the classic Brave Bird/Return combo, as well as Revenge to give the little duck a weapon against Rock and Steel types. Still, even with that decent power and coverage, it really doesn't have the speed or bulk to do anything resembling a sweep.
45 / 55 / 45 / 65 / 45 / 75
And if you thought Farfetch'd was bad, meet Delibird. Not only are its stats poor, its typing does it no favors either. It's not so much that Delibird is incapable of doing damage. With Hustle and a Choice Band, Delibird is hitting with decent power. It also has access to Ice Shard and the powerful Focus Punch, very good options. However, its other STABs are weak, and the little Santa bird will most likely die in one hit. At least it has Rapid Spin…yeah, unless it's December, don't use Delibird.
…the Bees...
61 / 90 / 45 / 50 / 50 / 160
Although the fall to NU is drastic, Ninjask pretty much picks up where it left off in 4th Gen; Baton Passing Speed Boosts and Swords Dances. Ninjask is infamous for setting up a Swords Dance, using Substitute and Protect to stall a few turns for Speed Boosts, and then Baton Passing those boosts (and if it's lucky, a Substitute) to an ally who needs it. It can also do a little damage with X-Scissor coming of its decent base 90 Atk, and…well, that's just about it. Ninjask is a one trick pony, but it's pretty good at what it does.
60 / 45 / 50 / 80 / 80 / 70
Butterfree doesn't look like much at all based on its stats and typing alone. It's claim to fame, however, comes in two forms. First is its access to Compoundeyes, improving the accuracy of Sleep Powder (and to a lesser extent, Stun Spore) to near perfect levels. The second is the new boosting move: Quiver Dance. This allows Butterfree to quickly become an offensive threat, while also making Butterfree a special tank of sorts. This combination of Sleep Powder and Quiver Dance is what makes Butterfree a very real threat. The butterfly can even forgo Compoundeyes for Tinted Lens, sacrificing some accuracy for a nearly unresisted Bug Buzz, further improving its offensive potential.
70 / 60 / 62 / 80 / 82 / 60
Masquerain may seem like just another Quiver Dancer at first, but it definitely has some edges over the others. First is its Intimidate ability, which allows Masquerain to better handle physical attacks while Quiver Dance boosts its tolerance for special hits. Secondly, Masquerain has a few impressive move options, such as Hydro Pump and Ice Beam. Finally, Masquerain is one of the few Pokemon capable of Baton Passing Quiver Dance. This alone gives this guy an edge over the competition, allowing it to either use the Quiver Dance boosts to sweep on its own or to pass them off to an even more powerful teammate.
70 / 94 / 50 / 94 / 50 / 66
Of all of the Quiver Dancers in NU, Mothim is the most powerful. Base 94 SpA is impressive, especially after boosted once or twice by Quiver Dance. What makes Mothim even more of an offensive threat is its access to Tinted Lens, giving it nearly unresisted coverage with its Bug STAB alone. Access to STAB Air Slash, complimented by the appropriate Hidden Power, gives Mothim even more coverage and an even greater chance to sweep. Unfortunately, the moth is still held back by its sub-par speed and frail defenses. Still, Mothim's power and coverage with Tinted Lens are reason enough to use it over the competition.
60 / 70 / 50 / 90 / 50 / 65
Beautifly looks strikingly similar to Mothim on the surface. Very similar stats (besides Mothim's greater Atk), similar movepools, access to Quiver Dance…overall, Beautifly is mostly outclassed by Mothim. Still, it isn't too bad on its own. The butterfly still has plenty of power, more so than Butterfree or Masquarain, and can be an offensive threat after Quiver Dance and its good coverage moves. It also has Stun Spore to set itself apart from Mothim. Still, between the two, I'd have to pick Mothim nearly every time.
70 / 80 / 102 / 80 / 102 / 40
Vespiquen's stats just scream "defensive Pokemon." Vespiquen is without a doubt the bulkiest Bug type in all of NU, and it does have a few assets to take advantage of that. Like Articuno, Vespiquen can use SubRoost, Toxic, and Pressure to wear opponents down and run the PP out of their coverage moves. Vespiquen also has a decent base 80 Atk stat and a good STAB move in Attack Order to prevent it from being a sitting duck. Still, that Bug/Flying typing really hurts it, and there's really not much it can do past SubRoost.
50 / 35 / 50 / 55 / 110 / 85
I'll be honest, I only included Ledian because not doing so would be rude. Even as far as some Pokemon go, Ledian is pathetic. The ladybug has terrible offenses, and its great SpD is destroyed by its low HP. It has decent speed and a good support movepool, but even then most of what it does is badly outclassed. It can Baton Pass Agilities and Swords Dances, but besides the useful utility of Encore, why do that when Ninjask is available? It can set up Screens too, but there are plenty of Pokemon who can do that far better. If only it had better offenses to take advantage of its good offensive movepool, boasting options like Mach Punch and Bug Buzz, but the sad fact is it doesn't. Just…don't use Ledian.
…and the Other Things
50 / 65 / 107 / 105 / 107 / 86
Rotom-S made a big splash in the NU metagame as the tier was forming. While its new typing may have left it outclassed by the other forms in the upper tiers (and some other Pokemon as well), it gave Rotom-S a new niche in NU. Even with that low base 50 HP, Rotom-S is still pretty bulky. It's great base 105 SpA and good base 86 speed also give it plenty of potential as an offensive beast. Its particular speed stat also allows it to check Pokemon like Scarf Sawk and Shell Smash Gorebyss with ease, and its new toy in Volt Switch gives it a great momentum-winning tool. Don't let the redundancy of its typing and ability fool you. Rotom-S is one of the most fearsome Pokemon in the metagame.
75 / 80 / 70 / 65 / 75 / 90
Golbat gained a new niche on the competitive scene with the Evolite, giving it the equivalent of 75/130/137 base defenses. With this impressive bulk, as well as its great typing that gives it a 4x resistance to Fighting, Bug, and Grass moves, Golbat finds its place as a fantastic defensive Pokemon. Base 90 speed is also pretty fast for a defensive threat, allowing Golbat to stall break effectively with Taunt. Super Fang is another neat option for breaking down walls, and Roost is the same reliable healing move it's always been. Golbat doesn't entirely fear opposing Taunts either, since its decent base 80 Atk stat makes Brave Bird a fearsome weapon. It does have some common weaknesses, but it can easily overcome these with a little support.
150 / 80 / 44 / 90 / 54 / 80
Drifblim is a weird Pokemon. It doesn't look like the kind of Pokemon to be sweeping, but it's perfectly capable of it. Despite its terrible defenses, it still maintains good bulk with its amazing HP stat. 90/80 offenses also make Drifblim into a nice special attacker. What really makes Drifblim shine, though, is Unburden. With Unburden, Drifblim can run an interesting ChestoRest set, setting up Calm Mind, Resting when needed, nabbing the Unburden speed boost, and then sweeping with the combination of Shadow Ball and a coverage move. Drifblim can also make an interesting Baton Passer, getting defensive boosts with Stockpile, enabling it to pass off those boosts and a very sturdy Substitute.
75 / 55 / 70 / 55 / 85 / 110
Jumpluff isn't really much for offense, and…it's not too much for defense either. At least, that's the way it looks on paper. However, with that impressive base 110 speed, Jumpluff becomes a very fast and successful SubSeeder. SubSeed Jumpluff isn't a one-man show; it might need some Toxic/Toxic Spikes support to increase its effectiveness. However, once set up, Jumpluff can stall for ages between Leech Seed and Substitute. Jumpluff is also set apart by its access to a very fast Sleep Powder and Encore, giving it some assets that many other SubSeeders don't have. Jumpluff can also be a good Sun supporter, and it has Memento to assist a partner's setup once its job is done.
65 / 40 / 70 / 80 / 140 / 70
Stat-wise, Mantine is the special version of Skarmory. Although it sounds like that would make Mantine a top-notch special wall, it sadly doesn't. Mantine lacks access to Roost, leaving it with only Rest for recovery. Still, Mantine does have its perks. Scald, Mantine's newest option, gives it the ability to threaten physical attackers with burns, allowing it to survive on both the physical and special side very well. It also has Water Absorb, making it a prime switch-in to many different Water types, especially since many of those Water types carry HP Grass over HP Electric for Quagsire. Even with the new sleep mechanics, RestTalk isn't too bad, healing all of Mantine's health while also healing off status.
55 / 40 / 85 / 80 / 105 / 40
Togetic has a newfound niche with the Evolite, giving it the equivalent of 55/152/182 defenses. That's bulky. I mean really bulky. Also, unlike many bulky Pokemon, Togetic has excellent reliable recovery in Roost. Togetic doesn't just sit there and look good, though. It has a pretty nice support movepool, boasting options like Thunder Wave, Heal Bell, Toxic, Encore, and Baton Pass. Togetic also has a decent base 80 SpA stat, giving it the ability to cause a little damage with Tri-Attack, which has a 40% chance to cause either a burn, paralysis, or freezing with Serene Grace. Underestimate this little fairy at your own peril; it won't go down easily.
67 / 57 / 55 / 77 / 55 / 114
Swoobat is just one of those Pokemon that can't wait for its Dream World ability to be released, in this case so it can start abusing Simple + Calm Mind. What it has now is Unaware combined with a base 114 speed stat, making it by far the fastest user of Unaware out there. It's also the fastest Dual Screen user in NU, and it has a few other useful support options to help with that role. Offensively, its good speed and passable SpA makes it a decent Calm Mind user. Unaware also means that Swoobat will be able to win Calm Mind wars more easily. Overall, though, Calm Mind Swoobat will be much better when Simple is released, giving it massive boosts after just two turns, as well as a very powerful Stored Power.
99 / 68 / 83 / 72 / 87 / 51
Tropius has a few interesting options that really set it apart as a Flying type. The most notable is Harvest, an ability unique to a small handful of Pokemon. With this ability, Tropius becomes a new kind of SubSeeder, using a limitless Sitrus Berry as its HP gets a little lower. This compiled with Tropius's great bulk makes it an excellent SubSeeder. It even gets Air Slash to punish those Grass types that are immune to Leech Seed. Tropius can also sweep with Chlorophyll, Growth, and its decent offensive movepool. Too bad Leaf Blade is illegal with Dragon Dance, or else Tropius would have that as an option as well.
55 / 75 / 60 / 75 / 60 / 103
Yeah, and you thought Garchomp's speed stat was trollish. Besides that great speed stat, however, Emolga doesn't have too much to its name. It can be a decent Agility Baton Passer, but Ninjask Baton Passes the speed boosts so much easier. Emolga does have a few neat options, such as Encore, which gives it a little something. Electric/Flying typing is pretty nice, too, and Emolga is capable of doing some damage with good offensive options on both sides of the spectrum. A fast Volt Switch is a neat tool as well. Emolga may not be the most powerful or bulkiest thing around, but it's got a little something to help it shine.
So there you have it. As you can see, there are a ton of Flying types that occupy NU, taking a variety of roles and niches. Each one has something special about it, making Flying types one of the most diverse and successful groups of Pokemon in the NU tier. So let's talk Flying types!
