387. Coccyzus americanus. 12¼ inches

This species is the most abundant in the southern part of its range, while the Black-bill is the most common in the North. Notice that the lower mandible is yellowish, that the wings are largely rufous, and that the outer tail feathers are black, with broad white tips, these points readily distinguishing this species from the next. The eggs of this species are large and paler colored than the next (1.20 × .90). They breed from the Gulf to southern Canada and winter in Central America.

BLACK-BILLED CUCKOO

388. Coccyzus erythropthalmus. 11¾ inches

Cuckoos are of quiet and retiring habits, but on account of their mournful notes are often regarded with awe by the superstitious. They are one of our most valuable birds, for they consume quantities of the fuzzy Tent Caterpillars, that are so destructive.

Their short, rounded wings and long, broad tails give them a silent, gliding flight that often enables them to escape unnoticed.

Note.—A low guttural croak, “cow,” “cow,” etc., repeated a great many times and sometimes varied with “cow-uh,” also repeated many times.

Nest.—Flat, shabby platforms of twigs placed at low elevations in thickets or on the lower branches of trees. The four greenish-blue eggs are 1.15 × .85.

Range.—United States and southern Canada, east of the Rockies. Arrives in May and leaves in September for northern South America.
