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.

How do you know if a bird has fledged?

Fledgling (13-14 days old or older).

This bird is fully feathered. Its wings and tail may be short, and it may not be a great flyer, but it can walk, hop, or flutter. It has left the nest, though its parents may be nearby, taking good care of it.

What month do birds have babies?

Most birds lay eggs anywhere from early spring until mid-summer, however the exact timing varies depending on how far north you are, and the particular species of bird you're watching. Some birds will even lay multiple sets of eggs, which is why you might continue seeing birds nesting well into summer.
