Behaviour

Little is known of the behaviour of this widespread, but shy and skulking, bird, which people hear far more often than they see. It appears to be a mainly solitary species. It has a curious appearance when in flight, resembling the flapping wings of a butterfly. The tail is spread and the wingbeats are slow and measured, and there is a brief pause when they are at the top of their beat above the bird.

. As with other parasitic cuckoos, parental care of eggs and young is provided by the host species. The female lays a single egg per parasitised nest; unlike other cuckoos the eggs are not very similar to the eggs of the host. On hatching the cuckoo chick kills any host chicks or removes their eggs. Chicks remain in their host's nests for 24 days after hatching.
