About Each Bird (Descriptions)
════════════════════════════════════════════════════════════════════════ #}
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.
Saint Helena Cuckoo (Nannococcyx psix) — ~25 cm. Extinct. Known only from subfossil remains from Saint Helena, South Atlantic. A small cuckoo inferred from bone morphology; likely became extinct following human colonisation of the island in the 16th century and the introduction of predators.
