Thank you for your assistance in preventing avoidable injuries to wildlife. Birds have a very poor sense of smell. This means young birds can be returned to the nest. The parents will continue to care for them, but only if you keep your distance. If an entire nest has blown out of a tree, the nest and babies can be put back up in the tree.
Baby birds are very difficult to hand-raise.
Their nutrition, temperature and housing requirements are very specific. Young birds must be fed every 20 minutes from dawn until dusk. It's illegal to keep them as pets or to raise orphans unless permitted by the state and federal governments. The parents will usually return soon to feed their young, but only if they feel that it is safe. Watch for any activity from inside your house or leave the area.
