NASHVILLE WARBLER
645. Vermivora rubricapilla. 4¾ inches
Male with a brown crown patch; female duller colored and with no crown patch. Dry side hills covered with young trees are favorite resorts for the Warblers. They conceal their nests on the ground under tufts of dead grass or overhanging stones. They are often rather shy and hard to sight, but you can usually hear their song, a lazy sounding “ker-chip-chip-chip-cherr-wee-e-e,” ending in a short trill. These birds breed in the northern half of the U. S. and southern Canada, wintering in Central America. A sub-species is found on the Pacific Coast.
ORANGE-CROWNED WARBLER
646. Vermivora celata. 5 inches
This species is fairly common in the Mississippi Valley but is rare in New England. Its habits are much like those of the last species and it is often mistaken for that bird. These birds breed only north of the U. S. and winter in Mexico. A sub-species, the Lutescent Warblers, nests from California to Alaska.
