In the western districts of the United Provinces the Indian cliff-swallows (Hirundo fluvicola) are beginning to construct their curious nests. Here and there a pair of blue rock-pigeons (Colombia intermedia) is busy with eggs or young ones. In the Punjab the ravens are likewise employed.

The nesting season of the hoopoe has now fairly commenced. Courtship is the order of the day. The display of this beautiful species is not at all elaborate. The bird that "shows off" merely runs along the ground with corona fully expanded. Mating hoopoes, however, perform strange antics in the air; they twist and turn and double, just as a flycatcher does when chasing a fleet insect. Both the hoopoe and the roller are veritable aerial acrobats. By the end of the month all but a few of the hoopoes have begun to nest; most of them have eggs, while the early birds, described in January as stealing a march on their brethren, are feeding their offspring. The 6th February is the earliest date on which the writer has observed a hoopoe carrying food to the nest; that was at Ghazipur.

March and April are the months in which the majority of coppersmiths or crimson-breasted barbets rear up their families. Some, however, are already working at their nests. The eggs are hatched in a cavity in a tree—a cavity made by means of the bird's bill. Both sexes take part in nest construction. A neatly-cut circular hole, about the size of a rupee, on the lower surface or the side of a branch is assuredly the entrance to the nest of a coppersmith, a green barbet, or a woodpecker.

As the month draws to its close many a pair of nuthatches (Sitta castaneiventris) may be observed seeking for a hollow in which to nestle. The site selected is usually a small hole in the trunk of a mango tree that has weathered many monsoons. The birds reduce the orifice of the cavity to a very small size by plastering up the greater part of it with mud. Hence the nest of the nuthatch, unless discovered when in course of construction, is difficult to locate.

All the cock sunbirds (Arachnechthra asiatica) are now in the full glory of their nuptial plumage. Here and there an energetic little hen is busily constructing her wonderful pendent nest. Great is the variety of building material used by the sunbird. Fibres, slender roots, pliable stems, pieces of decayed wood, lichen, thorns and even paper, cotton and rags, are pressed into service. All are held together by cobweb, which is the favourite cement of bird masons. The general shape of the nest is that of a pear. Its contour is often irregular, because some of the materials hang loosely from the outer surface.

The nursery is attached by means of cobweb to the beam or branch from which it hangs. It is cosily lined with cotton or other soft material. The hen, who alone builds the nest and incubates the eggs, enters and leaves the chamber by a hole at one side. This is protected by a little penthouse. The door serves also as window. The hen rests her chin on the lower part of this while she is incubating her eggs, and thus is able, as she sits, to see what is going on in the great world without. She displays little fear of man and takes no pains to conceal her nest, which is often built in the verandah of an inhabited bungalow.

As the month nears its end the big black crows (Corvus macrorhynchus) begin to construct their nests. The site selected is usually a forked branch of a large tree. The nest is a clumsy platform of sticks with a slight depression, lined by human or horse hair or other soft material, for the reception of the eggs. Both sexes take part in incubation. From the time the first egg is laid until the young are big enough to leave the nest this is very rarely left unguarded. When one parent is away the other remains sitting on the eggs, or, after the young have hatched out, on the edge of the nest. Crows are confirmed egg-stealers and nestling-lifters, and, knowing the guile that is in their own hearts, keep a careful watch over their offspring.

The kites (Milvus govinda) are likewise busy at their nurseries. At this season of the year they are noisier than usual, which is saying a great deal. They not only utter unceasingly their shrill chee-hee-hee-hee, but engage in many a squabble with the crows.

The nest of the kite, like that of the corby, is an untidy mass of sticks and twigs placed conspicuously in a lofty tree. Dozens of these nests are to be seen in every Indian cantonment in February and March. Why the crows and the kites should prefer the trees in a cantonment to those in the town or surrounding country has yet to be discovered.
