Coccyzus americanus

The yellow-billed cuckoo (Coccyzus americanus) is a cuckoo. 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 or thunderstorms. The genus name is from Ancient Greek kokkuzo, which means to call like a common cuckoo, and americana means 'of America'.
