Плачущая кукушка Cacomantis merulinus

A small and slender cuckoo, far more often heard than seen; the male's accelerating song, which decreases in volume as it progresses, is composed of a few whistled long notes followed by shorter, breathy notes. Adult male and typical (non-hepatic) female show orange belly, gray head, and brown back and tail. Hepatic, or rufous-morph, individuals are rusty brown above and white below, with black barring all over the body. Inhabits open woodlands, edges, and agricultural areas.
