Brood parasitism by Indian Hawk-cuckoo
G. Prasad, P.O. Nameer and M.V. Reshmi
The Indian Hawk-cuckoo Hierococcyx varius was found to be a brood parasite on Pale-capped Babbler Turdoides affinis (Jerdon) in Kerala Agricultural Univeristy Campus, Thrissur. The chances of babbler nests parasitised by cuckoos is maximum when they build nests on open-crowned and exposed trees at heights more than 5 m. However, the nest building materials and the flock size of the babbler family did not influence the cuckoo in selecting the host. The study also indicates that the cuckoo may be destroying the eggs or the chicks of the host.
