The Rock Thrush is an Eastern species that breeds sparingly from Central Europe eastwards through Southern Siberia and North China, and southwards in Greece, the Balkans, Asia Minor, and Persia. It has only once been obtained in our islands, namely in Hertfordshire in 1843. The male is greyish blue on the head, neck, and mantle; white on the rump, tail and under parts bright chestnut. The female is speckled brown above, chin and throat whitish, breast and under parts buff mottled with brown. Length 7·5 in.; wing 4·75 in. THE WHEATEAR Saxicola œnanthe (Linnæus) [Illustration: WHEATEAR _Saxicola œnanthe_ Adult male (right). Female (centre). Young in autumn (left)] Before the March winds have subsided, and while the trees and all vegetation are still in their winter sleep, the first of the Wheatears appears in the south-west of England. A lively and sprightly little chap is he, as he sits on a tussock of grass or on a fence, jerking his tail, or darting with a quick sharp flight to some other elevation, showing, as he does so, his conspicuous white rump, while his dark wing feathers and tail and grey back prevent the passer-by from mistaking him for any other species. He is a bird of the open, preferring large sandy stretches or wide moorlands, and it is only during migration that he affects woodlands and the more cultivated districts. As a rule the male birds are the first to arrive, being followed in about a week or ten days by the hens and less vigorous males. Having chosen his mate, about the first or second week in April, he will begin to look for a nesting-site, generally a little way down a rabbit-burrow, or in moorland districts a hole or crevice of a rock or stone wall will be chosen, but wherever placed it will be secure from observation. The nest is loosely built of grass, moss, rabbit fleck, fur, and feathers, or any material that comes handy, and having laid six or seven eggs of a uniform pale-blue colour the hen commences her business of incubation, in which the cock takes no part. He is, however, in constant attendance in the vicinity of the nest, frequently uttering his apology for a song, which consists merely of a few notes carelessly strung together, singing apparently rather from exuberance of spirits than because he really appreciates music, for often, as a spider or other insect comes within his range of vision, he will suddenly break off his song, seize the tempting morsel, and fly up again with his sharp “chack, chack.” The nest is somewhat difficult to find, and as a rule can only be discovered by watching the hen bird, who may be recognised by her browner tints; if, however, she suspects you of watching her, she will refuse to return for some considerable time. If you allow your attention to be diverted, she will seize the opportunity to dart home, and your trouble will have been in vain.
