Fledging is the interval between hatching and flight or leaving the nest. Some birds leave the nest within hours of hatching (precocial), but it might be weeks before they are able to fly. This is common with waterfowl and shorebirds. Until they start to fly, they are called fledglings. Birds that are still in the nest are called nestlings. Other baby birds are born naked and blind, and remain in the nest for several weeks (altricial).
