Locally we have two species of cuckoo-shrike, The White-bellied (or Little) Cuckoo-shrike Coracina papuensis and the more familiar Black-faced Cuckoo-shrike Coracina novaehollandiae. Both frequent similar habitat, the smaller species is less common and tends to favour fertile drainage lines. Both are specialist insectivores, preying largely on canopy insects including caterpillars.
Last Saturday I observed an aggressive encounter between a pair of C.papuensis and a number of C.novaehollandiae, as the smaller species were defending the territory around their nest site. Both adults were involved in nest-building, a partially constructed shallow bowl in a horizontal fork of a Grey Box.
