The goliath coucal is one of the largest coucals, a ground-favoring cuckoo that prefers dense undergrowth. Unlike many cuckoos, coucals are not brood parasites and build their own domed nests. It is shy and often detected by its deep, booming calls rather than seen. Its contrasting rufous wings and long black tail are key field marks in the northern Maluku Islands.
Temperament
shy and skulking
Flight Pattern
short rapid wingbeats followed by glides
Social Behavior
Usually seen singly or in pairs, maintaining territories in dense cover. Both sexes build a domed nest of leaves and grasses low in vegetation and share incubation and chick-rearing. Pairs communicate with deep duetting calls, especially at dawn.
Migratory Pattern
Resident
Song Description
Deep, resonant booming notes given in a slow series, often descending or accelerating. Calls carry far through forest understorey and are most frequent at dawn and dusk.
