Mourning dove - this patient came in recently because it flew into a window. Sadly, the stress of the situation caused her to lose all the feathers on her left wing and tail. These birds have a defense mechanism, which causes them to drop feathers to escape predators. Instead of catching the bird - a predator may end up with feathers in it's mouth or talons. There is no injury to the bird other than the feather loss - it will be wintering over with us while it molts. This is a good reminder to use a light towel when picking up injured birds and to keep the animal covered, dark, and quiet. Stressful situation can often further injure wildlife, or sadly sometimes cause their demise. Status – released.
