Female Kentucky Warbler ( Geothlypis formosa )
|( Wilson , 1811)|
The Kentucky warbler usually has an olive-green plumage on the top and a yellow one on the underside. Both sexes have a black crown. A distinguishing feature between males and females are the black parts on the face. In the female, less duller black plumage colorations are to be found than in the male. Their legs are pink in color.
The breeding season is from May to June. The clutch consists of three to six white or cream-colored, gray to brown speckled eggs in a nest that is hidden in the dense vegetation under a bush or in the tall grass. The eggs are hatched by the female in twelve to thirteen days without the assistance of the male. The chicks leave the nest after about ten days. As a brood parasite, the brown-headed cowbird ( Molothrus ater ) lays its eggs in the nest of the Kentucky warbler.
The Kentucky warbler breeds in humid habitats such as swamps and forests in southeastern North America , from the southeast in Nebraska , south in Iowa and Wisconsin to southwest Connecticut . To the south of it are its breeding areas in Texas and Florida . In winter he moves to the north of Colombia and the northwest of Venezuela, among other places .
