Yellow-billed Cuckoo

Coccyzus americanus

The yellow-billed cuckoo 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". Source
