Cornell University (Ornithologists) describes this bird as common but secretive, often heard rather than seen. It mainly eats caterpillars and can be heard through out the night during breeding season.
My nephew Matt saw a cuckoo on a birding walk in Mountain Lake last week. I could not remember seeing you but knew how it looked. Later I looked in our old bird guide and it was checked as sited, but it has been a long time. Two days ago we had a black-billed cuckoo in our backyard. Thank you Matt!
