The Yellow-billed Cuckoo is a secretive bird of dense deciduous thickets known for its guttural, bubbling 'ka-ka-ka-ka-kow-kow-kowp' call — a traditional weather prognosticator among rural Americans who call it the 'rain crow.' Unlike its European cousin, it almost always raises its own young, though it occasionally lays eggs in other birds' nests. It can eat tent caterpillars that other birds avoid due to their irritating hairs.
