The adult male is slate grey with white rump and white under parts, the throat and breast being bluish grey. The female and young are brown above with the exception of the rump, which is white; tail brown with five dark bars, whence the name “Ring Hawk,” which is applied to the females and young of this species. Length 21 in.; wing 15 in. MONTAGU’S HARRIER Circus cineraceus (Montagu) Although the commonest of our British Harriers, this species is nevertheless exceedingly scarce and local. It is a migrant, arriving towards the middle of April, and in some of the open moorlands and fenny localities in the south and south-east of England a few pairs yearly attempt to breed. The sight of this grand bird, as it quarters the ground backwards and forwards in search of food, is an exquisite pleasure to the true naturalist, but in spite of the protection afforded by law, it is ruthlessly destroyed, either by the gamekeeper or the collector of British killed specimens, whenever seen. In habits it closely resembles the Hen Harrier. It nests on the ground, and its bluish white eggs are, as in the case of that species, often speckled with rusty red. The upper parts, throat, and breast of the male are slaty grey; the hinder parts white, streaked with rufous on the flanks. Tail feathers greyish with five rusty red bars on all except the middle pair. The female, who is slightly larger than the male, is brown above and buff streaked with rufous below. The young resemble the female but are much darker below. Length about 18 in.; wing 15·4 in. To Scotland and Ireland this bird is only a very rare straggler. THE COMMON BUZZARD Buteo vulgaris, Leach Years ago this species might fairly have been called common in our islands, but the gamekeeper, who has much to answer for in the extirpation of many species, has not failed to wage war on this beautiful bird. If we still want to see him, as he soars round in graceful curves over his forest home, we shall have to journey to the wilder parts of Wales and Scotland, where alone he is still able to hold his own. Over the rest of our islands he is, as a breeding species, no longer extant, though every year a few migrants from abroad seek our hospitality, only to be killed by the first keeper that sees them. The nest is placed either on a ledge of a cliff or in the fork of a tree, and is a bulky structure of sticks, lined and surrounded with fresh leaves, which are continually renewed as they wither. The eggs, four in number, are bluish white, marked with rusty red near their larger end. Both sexes incubate, and if the nest be approached, circle round and round the intruder with piteous “mewing” note. As far as game birds are concerned, this species is practically harmless, feeding almost entirely on ground game, frogs, and reptiles, so that no one can have any excuse for destroying it.
