The nest of the dove is a subject over which most ornithologists have waxed sarcastic. One writer compares the structure to a bundle of spillikins. Another says, “Upset a box of matches in a bush and you will have produced a very fair imitation of a dove’s nursery!” According to a third, the best way to make an imitation dove’s nest is to take four slender twigs, lay two of them on a branch and then place the remaining two crosswise on top of the first pair. For all this, the dove’s nest is a wonderful structure; it is a lesson in how to make a little go a long way. Doves seem to place their nurseries haphazard on the first branch or ledge they come across after the spirit has moved them to build. The nest appears to be built solely on considerations of hygiene. Ample light and air are a sine qua non; concealment appears to be a matter of no importance.
In India winter is the time of year at which the larger birds of prey, both diurnal and nocturnal, rear up their broods. Throughout January the white-backed vultures are occupied in parental duties. The breeding season of these birds begins in October or November and ends in February or March. The nest, which is placed high up in a lofty tree, is a large platform composed of twigs which the birds themselves break off from the growing tree. Much amusement may be derived from watching the struggles of a white-backed vulture when severing a tough branch. Its wing-flapping and its tugging cause a great commotion in the tree. The boughs used by vultures for their nests are mostly covered with green leaves. These last wither soon after the branch has been plucked, so that, after the first few days of its existence, the nest looks like a great ball of dead leaves caught in a tree.
The nurseries of birds of prey can be described neither as picturesque nor as triumphs of architecture, but they have the great merit of being easy to see. January is the month in which to look for the eyries of Bonelli’s eagles (Hieraetus fasciatus); not that the search is likely to be successful. The high cliffs of the Jumna and the Chambal in the Etawah district are the only places where the nests of this fine eagle have been recorded in the United Provinces. Mr. A. J. Currie has found the nest on two occasions in a mango tree in a tope at Lahore. In each case the eyrie was a flat platform of sticks about twice the size of a kite’s nest. The ground beneath the eyrie was littered with fowls’ feathers and pellets of skin, fur and bone. Most of these pellets contained squirrels’ skulls; and Mr. Currie actually saw one of the parent birds fly to the nest with a squirrel in its talons.
Bonelli’s eagle, when sailing through the air, may be recognised by the long, hawk-like wings and tail, the pale body and dark brown wings. It soars in circles, beating its pinions only occasionally.
