Colima Warblers, Vermivora crissalis


Photo Wanted The Colima Warblers (Vermivora crissalis) is mainly found in the Sierra Madre Occidental of central Mexico, though its range just barely extends into adjacent south-western Texas in the Chisos Mountains of Big Bend National Park.

Breeding / Nesting

The Colima Warbler measures about 4½ to 5 inches in length.

The plumage is mostly dark grey and brownish above, with a pale under-side. The rump and the feathers below their tail are yellow. They have a white ring around their eye, and a tinge of pale color on the chest.

Males can be identified by a spot of orange on the top of their heads.

The Virginia's Warbler has much more yellow or pale color on their chest, which is more grey in the Colima Warbler. The yellow above and below the tail is also more orange-yellow in the Colima's Warbler, and more greenish-yellow in Virginia's Warblers.

Breeding / Nesting

They mostly nests on the ground, forming loose cup-shaped nests of grass, leaves and moss - often hidden among the mountain rocks. The average nest consists of four eggs, which are white to cream-colored and speckled with brown.
