The yellow-billed cuckoo (Coccyzus americanus) is a member of the cuckoo family. Common folk names for this bird in the southern United States are rain crow and storm crow. These likely refer to the bird's habit of calling on hot days, often presaging rain showers or thunderstorms. The genus name is from the Ancient Greek kokkuzo, which means to call like a common cuckoo, and americanus means "of America".
Taxonomy
The yellow-billed cuckoo was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. He placed it with all the other cuckoos in the genus Cuculus and coined the binomial name Cuculus americanus. Linnaeus based his description on the "Cuckow of Carolina" that had been described and illustrated in 1729–1732 by the English naturalist Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands. The yellow-billed cuckoo is now placed with 12 other species in the genus Coccyzus that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. The genus name is from the Ancient Greek kokkuzō meaning "to cry cuckoo". The species is monotypic: no subspecies are recognised.
Description
Comparison of black-billed cuckoo (left) and yellow-billed cuckoo
Adults have a long tail, brown above and black-and-white below, and a black curved bill with yellow especially on the lower mandible. The head and upper parts are brown and the underparts are white. There is a yellow ring around the eye. It shows cinnamon on the wings in flight. Juveniles are similar, but the black on the undertail is replaced by gray. The adults show no sexual dimorphism, and thus the males and females can't be told apart by plumage.
