Fusion Avian

Avian mutates have had their DNA fused with the DNA of any warm-blooded vertebrate of the class Aves, having a body covered with feathers, forelimbs modified into wings, scaly legs, a beak, and no teeth, and bearing young in a hard-shelled egg. This includes the various prehistoric versions.

Traits
These mutates tend to have certain behaviors, as well as bodily features, of the bird that they are fused with. For instance, they will generally have wings, either fused with their arms or on their backs, with the exception of flightless birds, such as penguins, ostriches, kiwis, etc.
