Whistling Yellowbill (Ceuthmochares australis) — 30–35 cm. Very similar to Chattering Yellowbill — grey plumage; yellow bill; long tail — but distinguished by its melodic whistled song rather than chattering calls. Found in forest and forest edge in East and Southeast Africa from Kenya to Mozambique. Non-parasitic. Insectivore.
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.
