Life cycle & population of the Vireo olivaceus & Aves

Life cycle: Vireo olivaceus reproduces by laying eggs in a nest. The eggs hatch after about two weeks and the young birds remain in the nest for another two weeks before they fledge.

During the breeding season, the adults form pairs and build nests. The adults will then lay eggs and the cycle begins again.

Average offspring size: 10-14 cm
