The time for incubation varies widely from species to species.
Roughly speaking, small songbirds take between 10 days and 2 weeks to hatch and the same amount to fledge. Larger birds such as woodpeckers may take 3 weeks to a month to fledge. Many ducks, shorebirds and gamebirds leave the nest immediately after hatching.
