Yellow warbler Facts
Yellow warbler is small songbird that belongs to family of New World warblers. There are 35 subspecies of yellow warblers that can be found in North, Central and South America. Yellow warbler inhabits edges of the forests and swamps, areas near the streams and rivers, mangrove forests and orchards. Yellow warbler can be found on the altitude of 9.000 feet. Habitat destruction, pollution of the ground with pesticides and accidental collisions with man-made objects represent major threats for the survival of yellow warblers in the wild. Despite these factors, yellow warblers are numerous and widespread (especially) in the North America.

Brown-headed cowbirds lay their eggs in the nests of yellow warblers. When yellow warbler detects "fraud", it builds new nest on top of already existing one and lays new set of eggs.
Female lays 3 to 6 greenish-white eggs covered with brown spots. Eggs hatch after 10 to 13 days. Male guards the nest and provides food during the incubation period.
Both parents provide food for the chicks while they are in the nest (during the first 9 to 12 days) and two more weeks after fledging (until they become ready for the independent life). Yellow warblers reach sexual maturity at the age of 1 year.
Yellow warbler can survive around 10 years in the wild.
