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.
The female lays 3-5, slightly glossy, pale bluish-white to white eggs (see Harrison [1979] for a photo of markings). The incubation period is 12-13 days and nestlings fledge 9-12 days after hatching and feed themselves 2 weeks after leaving the nest. Two successful clutches may be raised in one season.Rates of parasitism by Brown-headed Cowbirds (Molothrus ater) vary widely (Harrison 1979, Nolan et al.2002).he incubation period is 12-13 days and nestlings fledge 9-12 days after hatching and feed themselves 2 weeks after leaving the nest.
