Presence of Common Hawk-cuckoo is easily detected at our campus whole year by its loud calls. It is specifically more vocal in summer. We can hear its calls literally throughout the day, early mornings are their favourite time for singing. In fact these manic, piercing calls sometimes gets on our nerves and earned its famous nickname ‘brain-fever bird’.
The call of this bird also popularly transcribed as brain-fever in English from its remarkable resemblance to the word "brain- fever… brain-fever…” repeated 5-6 times in a piercing voice running up the scale.
The bird is called “બાપૈયો -Bappaiyo” in our Gujarati language. Here in Gujarat farmers consider call of Common Hawk-cuckoo as good omen…! Rural people believes call of Common Hawk-cuckoo is a sign of rain coming very soon…!
The common hawk-cuckoo is a medium- sized cuckoo, with distinctive yellow eye ring, easily mistaken for Shikra. But then easily separate by cuckoo-like bill, broadly barred tail and no mesial strip. The plumage is ashy grey above; whitish below, cross-barred with brown.
They seems to be active and easily spot after the first rain, most possibly because of their breeding season. Like other cuckoos, Common Hawk-cuckoo also have no taste for the trouble and responsibility of raising a chicks, certainly nest-parasitic, make other birds do their duty. Clearly Common birds dislike its presence and usually raise the alarming call.
The species is arboreal, generally found single, perched silently on lower branches of roadside trees. Flies low between nearby branches at first approach with fast audible wing-beats, more like glide, before disappear. We saw Common hawk-cuckoo hunt mainly insects, earthworms, caterpillars etc. from wet grassy soil. We observed a common hawk cuckoo following a group of large grey babblers, both species can hunt and feed on hairy caterpillars which are plenty in this region during rainy season. They pick caterpillar, squeeze and rub to remove unwanted parts before eating. Once we saw Common hawk-cuckoo share hunting ground along with Indian Roller, Red-wattled lapwing, Common Myna and Black Drongo. At other time we witnessed Common hawk-cuckoo feeding on fruits of Indian fig tree.
