Doctor Mid-Nite, The Falcon and Birdman

I think that is a superhero is going to have an animal mascot, a bird is the best way to go.  They're great for providing reconnaissance or passing on information. I also like the idea of heroes having a psychic bond with their avian companions, so that they can see what the bird sees as it flies ahead of them.  It might be fun to get a bunch of these bird-loving heroes for an action packed tale.
