kukačka černozobá Coccyzus erythropthalmus

Slender, long-tailed bird more often heard than seen. White below and brown above, with black bill. Separated from Yellow-billed Cuckoo by bill color, uniformly brown outer wings (not rufous) and smaller white spots on underside of tail. Feeds mainly on caterpillars and other insects. Found mostly in deciduous woodlands, especially areas with thick secondary growth. Often sits motionless for long periods of time and is difficult to spot. Listen for its song, a repeated series of soft "cu-cu-cu" notes.
