Young birds have the feathers of the upper parts margined everywhere with pale rufous ; the upper tail-coverts are pure white; the ruff is unstreaked and very distinct; the lower parts-are rufous-buff or buff with faintly showing darker rufous shafts on breast and flanks.

Distribution. Breeding East Europe, Northern Africa and West and Central Asia to the Altai. In Winter it is found over the greater part of India and Burma. It occurs in Ceylon but in Burma has not occurred as far South as Tenasserim.

Nidification. This Harrier breeds in South-East Europe and Western Asia, making a nest on the ground consisting oil a bed of leaves and grass in a natural hollow. The site selected is usually one on a dry open plain but Kuschel found them breeding at the edge of a swamp in South Russia. The eggs number four or five and in shape are broad obtuse ovals. Most eggs are white or very faintly marked but a few are marked with pale reddish, or with pale pinkish-grey or with both, the blotches fairly large and scattered over the whole surface of the egg. Seventy-eight eggs (Jourdain & Rey, 69) average 44.6 x 34.7 mm.: maxima 50.0 X 37.0 mm.; minima 40.1 X 35.0 and 43.2 x 336 mm. The breeding-season is April and May.

Habits. The Pale Harrier is a bird of the drier steppes and plains and even in India, where it is it Winter visitor only, is more partial to dry wastes than to wet cultivation, though I have seen it hawking over rice-fields and swamps.
