Western Koel (Eudynamys scolopaceus) — 39–46 cm. Male glossy black; female brown with white spots and barred underparts; red eye. Widespread from South Asia through mainland Southeast Asia. Brood parasite targeting crows and mynas. Frugivore and insectivore. Its rising wailing call heralds the Indian summer.
