About Each Bird (Descriptions)
════════════════════════════════════════════════════════════════════════ #}
Black Coucal (Centropus grillii) — 30–35 cm. Entirely glossy black with chestnut wings in breeding plumage; non-breeding birds streaked brown. Found in tall grass and reed beds across sub-Saharan Africa. Non-parasitic; notable for reverse sex roles — female larger, male incubates and raises young. 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.
