If you find an injured bird, place it on a soft cloth or towel in a small animal carrier or box with airholes. If the box has an open top, cover it with a towel (while still allowing air) to keep the bird calm. Call a wildlife rehabilitator immediately. DO NOT ATTEMPT TO FEED THE BIRD. When attempting to move a bird, remember to not use a lot of pressure when holding it, as their bones can break very easily. For your own safety, do not try to capture large injured raptors like eagles, owls, or ospreys; call a wildlife professional in your area instead.
“Orphaned” birds and animals may not necessarily be orphans. Be sure to look around to see if you can find the parents before assuming the baby is orphaned. For nestlings who’ve fallen out of a nest, try to see if the nest is low enough for you to return them to it. (It’s false that a bird will no longer care for its offspring if a human has touched it.) If you find yourself in this situation, please see the two Audubon articles mentioned on this page or call a wildlife clinic.
