The distribution of this bird in the British Islands is very partial, for it is unknown in Ireland, of rare occurrence in Scotland, and in England is found chiefly in the midland and southern counties. During the summer months it is generally dispersed throughout Europe and the temperate parts of Siberia, and as autumn approaches, it crosses the Mediterranean into Africa, where it travels down the east coast through Egypt, Nubia, and Abyssinia, to Natal, and on the west coast has been met with in Great Namaqua Land, Damara Land, and the Okavango region, where, according to Andersson, it breeds.[114] Breeding in its winter quarters? Well, that is the question. Can the birds which Andersson found nesting in South-west Africa in our winter, have been the same birds which reared a brood in Europe the previous summer? He says it is migratory in Damara Land. Is the same species, then, found on both sides of the equator, migrating north and south on both sides of it, but never crossing it? The late Mr. Blyth thought that, with one exception, our summer migratory birds do not breed in their winter quarters, but from what has been recorded of the Swallow, the Sandmartin, the Wryneck, the Turtle-Dove and the present species, there seems room to doubt the correctness of this view. Another species of Shrike, the Woodchat (_Lanius rutilus_), has been met with in this country during the summer months, and has been reported even to have nested here. It is of extremely rare occurrence, however, and cannot with propriety be included, at least for the present, amongst our annual summer migrants. [Illustration: TURTLE-DOVE] THE TURTLE-DOVE. (_Turtur auritus._) Amidst the general harmony of the grove in spring, there are few prettier sounds than the gentle cooing of the Turtle-Dove. Perched upon a bough at no great height from the ground, it pours forth its soft murmurings with a delightful _crescendo_ and _diminuendo_, while close at hand, upon a mere frame-work of a nest, the mate sits brooding upon her two milk-white eggs. Arriving in this country towards the end of April or beginning of May, the Turtle-Dove is seen only in pairs until the young are able to fly. Young and old then unite in flocks, and ten or a dozen may often be found together in the pea-fields and on the stubble, where they pick up the fallen grain. They are very partial also to vetches, rape, and wild mustard, and do some service to farmers by ridding the cultivated lands of the seeds of numerous weeds, such as the Corn Spurrey (_Spergula arvensis_), which is common in corn-fields, and the Silver-weed (_Potentilla anserina_), which they find upon the fallows.
