A slim bird, with a brown back and plain white breast. It has a reddish tent in the wings and has large white spots at the tips of its black tail feathers. The yellow-billed cuckoo has a narrow yellow eye-ring and the lower bill of its beak is yellow.
Their call is a rapid, throaty call of ka-ka-ka-ka-ka-ka-ka-ka-ka-ka-ka-ka-kow-kow-kowlp-kowlp-kowlp-kowlp (with the call slowing towards the end).
They can be found in woodlands, thickets, and orchards.
They eat large insects, caterpillars, some fruit, and seeds.
They can be found from New Hampshire and Vermont down to southern Vermont, and westward towards the Dakotas down to Texas, with some isolated populations in Utah and Idaho.
The yellow-billed cuckoo and black-billed cuckoo have something in common. Both species’ young mature at a very fast rate. From egg laying to fledglings leaving the nest is approximately 17 days. Around day 6 or 7, the young grow their feathers. The feathers burst out of their sheaths, and within two hours, the young are completely feathered.
Black-billed cuckoo and mangrove cuckoo.
