Young birds appear to be more yellow below than adults, which in some cases are quite pure white.

Distribution. Breeding in Eastern Siberia, the hills of Northern China, Burma and Assam. In Winter South to India, West of a line drawn from the Sutlej Valley to the Gulf of Cam bay, Ceylon, the Indo-Chinese countries and Burma to Singapore, Java,, Sumatra and Borneo and South China.

Nidification. The only nests known of this Wagtail were taken in N. Cachar in May and in North-East Chihli in July. In all four instances they were made of grass, leaves, moss, roots and a few soft fine twigs, all bound and felted together with cobwebs and with the edges neatly finished off with the same material. The lining was hair over fine roots, in N. Cachar the hair being that of the Serow and Gayal, in China that of horse and cattle. All four nests were built on horizontal branches, the two found by myself being on branches of small trees growing in among the boulders on banks of streams in dense evergreen forests. Like the nests the eggs bear no resemblance to those of Wagtails but might easily be mistaken for those of Chaffinches. The groundcolour is blue-grey to almost pale slaty-grey and the marks consist of bold spots and small blotches of black or dark red with the edges, looking as if they had run, of paler red. The markings, with a few underlying ones of grey, are dotted irregularly over the whole surface. Maxima 20.9 x 15.1 and 20.3 x 15.3 mm.; minima 19.0 X14.7 mm.

Habits. This is almost entirely a forest bird, being found only in evergreen forest, where it haunts open glades, forest paths and riversides. Occasionally it occurs on the banks of rivers running through open but well-wooded country and Jerdon records having seen it in his own garden at Nellore. The birds are generally to be met with in pairs and when disturbed in forest roads they fly along in front of one, alighting every hundred yards or so and making little runs just like a Wagtail until, finally f i hey dive into the forest and return again to the open path behind the intruder. They are not shy birds and will allow a close approach, whether running about in stream or on path or perching, as they often do, on some low branch or high boulder. Their food consists of small slugs, snails, tiny worms and all kinds of insects and they pursue these latter into the air as well as snatching them off the blades of grass. Their movements are very quick and they keep up a constant wagging of their tails, hut the movement is lateral, not vertical as in the true Wagtails. Their flight is fairly swift and dipping, consisting of alternate rapid beating of the wings and sailing with them semi-closed. The note is a loud chirrup, frequently repeated when flying, running or perching.
