I'd go with Moltres or Articuno. Moltres is an amazing pokemon and has some awesome lore as well. I mean c'mon, he has plumage made of fire, swims in lava to heal and whenever he migrates the seasons change. What's not to love about Moltres?

I personally think it's the coolest designed non-legend bird as of now. Shame how it's kinda like an inferior Staraptor.
2nd is Talonflame. Overattedness aside, Talonflame is based off my favorite pirds of prey, the peregrine falcon. It's also nice to see a fire/flying type that's viable and a starter bird that's good after the underwhelming Unfezant
For legendary, I'd say Yveltal. Just...death Avion of desctruction and death and life syphoning of awesomeness
