Cocos Cuckoo (Coccyzus ferrugineus) — 31–35 cm. Richly rufous-brown above; cinnamon-buff below; graduated tail; yellow lower mandible. Endemic to Cocos Island, Costa Rica (a UNESCO World Heritage Site). Non-parasitic. Insectivore. Vulnerable due to its extremely restricted range and introduced predators.
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.
