spring and summer wildlife rehabilitators get numerous calls from people
claiming to have found a bird with a broken wing. Most often, what they
have is a young bird in the fledgling stage of life.
Fledglings are young birds that have
already left the nest, or have been evicted by the parents. These babies
are usually unable to fly for a couple of weeks. This is a very
important time for the young to put the finishing touches on learning
about survival by observing their parents. They will learn about finding
food, avoiding predators, and how to fly.
can be as large as the parents (sometimes appearing even larger), and
fully feathered. Fledglings are able to hop, but not yet fly. A bird
with a broken wing will hold the injured wing lower than the good wing.
Most broken wings will droop very low, and are fairly easy to identify.
Please leave the fledglings alone. They will do fine without your help.
All you need do is keep pets and children away from them.
