Range. - United States east of the Rocky

Mountains; north to Labrador and Manitoba; south in winter to Central and South America. This species is rather more common in the northern part of the

United States than the

Yellow - billed variety.

The bird is smaller, has a blackish bill, and the tail is the same color as the back and only slightly tipped with white.

Their nests are built in similar locations and of the same materials as used by the Yellow-bill; the three or four eggs are smaller and a darker shade of greenish blue. Size 1.15 x .85. All the Cuckoos are close sitters and will not leave the nest until nearly reached with the hand, when they will slowly flutter off through the underbrush, and continue to utter their mournful "Kuk-kuk-kuk," many times repeated.

Black-billed Cuckoo.
