Best Answer: It varies by species..but most passerines (perching birds) take approximately 2 weeks to hatch their eggs, and usually another 2 weeks before the young leave the nest.
Incubation time is roughly correlated with the weight of the egg. The eggs of small songbirds generally hatch in about 11 days; those of the Royal Albatross in about 80 days. More information on incubation, based on careful, long-term observations of nests, is needed for most species of North American birds.
