The iora is a feathered exquisite, about the size of a tomtit. The cock is arrayed in green, black and gold; his mate is gowned in green and yellow.
The iora has a great variety of calls, of these a soft and rather plaintive long-drawn-out whistle is uttered most frequently in April and May.
In shape and size the nest resembles an after-dinner coffee cup. It is beautifully woven, and, like those of the white-eye and fantail flycatcher, covered with cobweb; this gives it a very neat appearance. In it are laid two or three eggs of salmon hue with reddish-brown and purple-grey blotches.
Throughout April the sprightly tailor-birds are busy with their nests. The tailor-bird (Orthotomus sutorius) is a wren with a long tail. In the breeding season the two median caudal feathers of the cock project as bristles beyond the others. The nest is a wonderful structure. Having selected a suitable place, which may be a bush in a garden or a pot plant in a verandah, the hen tailor-bird proceeds to make, with her sharp bill, a series of punctures along the margins of one or more leaves. The punctured edges are then drawn together, by means of strands of cobweb, to form a purse or pocket. When this has been done the frail bands of cobweb, which hold the edges of the leaves in situ, are strengthened by threads of cotton. Lastly, the purse is cosily lined with silk-cotton down or other soft material. Into the cradle, thus formed, three or four white eggs, speckled with red, find their way.
In April cavities in trees and buildings suitable for nesting purposes are at a premium owing to the requirements of magpie-robins, brahminy mynas, common mynas, yellow-throated sparrows and rollers. Not uncommonly three or four pairs of birds nest in one weather-beaten old tree.
Bank-mynas, white-breasted kingfishers, bee-eaters and a few belated sand-martins are nesting in sandbanks in cavities which they themselves have excavated. The nests of the kingfisher and the sand-martin have already been described, that of the bank-myna belongs to May rather than to April.
Bee-eaters working at the nest present a pleasing spectacle. The sexes excavate turn about. The site chosen may be a bunker on the golf links, the butts on the rifle range, a low mud boundary between two fields, or any kind of bank. The sharp claws of the bee-eaters enable the birds to obtain a foothold on an almost vertical surface; this foothold is strengthened by the tail which, being stiff, acts as a third leg. In a surprisingly short time a cavity large enough to conceal the bird completely is formed. The bee-eater utilises the bill as pickaxe and the feet as ejectors. The little clouds of sand that issue at short intervals from each cavity afford evidence of the efficacy of these implements and the industry of those that use them.
Two of the most charming birds in India are now occupied with family cares. These are both black-and-white birds—the magpie-robin (Copsychus saularis) and the pied wagtail (Motacilla maderaspatensis). The former has already been noticed as the best songster in the plains of India. The pattern of its plumage resembles that of the common magpie; this explains its English name. The hen is grey where the cock is black, otherwise there is no external difference between the sexes. For some weeks the cock has been singing lustily, especially in the early morning and late afternoon. In April he begins his courtship. His display is a simple affair—mere tail-play; the tail is expanded into a fan, so as to show the white outer feathers, then it is either raised and lowered alternately, or merely held depressed. Normally the tail is carried almost vertically. The nest is invariably placed in a cavity of a tree or a building.
The pied wagtail always nests near water. If not on the ground, the nursery rests on some structure built by man.
A visit to a bridge of boats in April is sure to reveal a nest of this charming bird. Hume records a case of a pair of pied wagtails nesting in a ferry-boat. This, it is true, was seldom used, but did occasionally cross the Jumna. On such occasions the hen would continue to sit, while the cock stood on the gunwale, pouring forth his sweet song, and made, from time to time, little sallies over the water after a flying gnat. Mr. A. J. Currie found at Lahore a nest of these wagtails in a ferry-boat in daily use; so that the birds must have selected the site and built the nest while the boat was passing to and fro across the river!
