HARRIER , or See also:

HEN-HARRIER, name given to certain birds of See also:prey which were formerly very abundant in parts of the See also:British Islands, from their See also:habit of harrying poultry. The first of these names has now become used in a generic sense for all the See also:species ranked under the genus See also:Circus of Lacepede, and the second See also:con-fined to the particular species which is the Falco cyaneus of See also:Linnaeus and the Circus cyaneus of See also:modern ornithologists. One See also:European species, C. aeruginosus, though called in books the See also:marsh-harrier, is far more commonly known in See also:England and See also:Ireland as the See also:moor-See also:buzzard. But harriers are not, like buzzards, arboreal in their habits, and always affect open See also:country, generally, though not invariably, preferring marshy or fenny districts, for See also:snakes and frogs See also:form a See also:great See also:part of their See also:ordinary See also:food. On the ground their See also:carriage is utterly unlike that of a buzzard, and their See also:long wings and legs render it easy to distinguish the two See also:groups when taken in the See also:hand. All the species also have a more or less well-See also:developed See also:ruff or frill of small thickset feathers surrounding the See also:lower part of the See also:head, nearly like that seen in owls, and accordingly many systematists consider that the genus Circus, though undoubtedly belonging to the Falconidae, connects that See also:family with the Striges. No osteological See also:affinity, however, can be established between the harriers and any See also:section of the owls, and the superficial resemblance will have to be explained in some other way. Harriers are found almost all over the See also:world,l and ' The See also:distribution of the different species is rather curious. while the range of some is exceedingly wide,—one, C. maillardi, seems to be limited to the See also:island of See also:Reunion (See also:Bourbon).fifteen species are recognized by See also:Bowdler See also:Sharpe (See also:Cat. Birds Brit. Museum, i. pp. 50-73). In most if not all the harriers the sexes differ greatly in See also:colour, so much so that for a long while the See also:males and See also:females of one of the commonest and best known, the C. cyaneus above mentioned, were thought to be distinct species, and were or still are called in various European See also:languages by different names.

The See also:

error was maintained with the greater persistency since the See also:young males, far more abundant than the adults, See also:wear much the same plumage as their See also:mother, and it was not until after See also:Montagu's observations were published at the Hen-Harrier (Male and See also:Female), beginning of the 19th See also:century that the " ringtail," as she was called (the Falco pygargus of Linnaeus), was generally admitted to be the female of the " hen-harrier." But this was not Montagu's only See also:good service as regards this genus. He proved the hitherto unexpected existence of a second species,2 subject to the same diversity of plumage. This was called by him the ash-coloured See also:falcon, but it now generally bears his name, and is known as I\/Iontagu's harrier, C. cineraceus. In habits it is very similar to the hen-harrier, but it has longer wings, and its range is not so northerly, for while the hen-harrier extends to See also:Lapland, Montagu's is but very rare in See also:Scotland, though in the See also:south of England it is the most See also:common species. Harriers indeed in the British Islands are rapidly becoming things of the past. Their nests are easily found, and the birds when nesting are easily destroyed. In the south-See also:east of See also:Europe, reaching also to the Cape of Good See also:Hope and to See also:India, there is a See also:fourth species, the C. swainsoni of some writers, the C. pallidus of others. In See also:North See also:America C. cyaneus is represented by a kindred form, C. hudsonius, usually regarded as a good species, the adult male of which is always to be recognized by its rufous markings beneath, in which See also:character it rather resembles C. cineraceus, but it has not the long wings of that species. South America has in C. cinereus another representative form, while See also:China, India and See also:Australia possess more of this type. Thus there is a section in which the males have a strongly contrasted See also:black and See also:grey plumage, and finally there is a See also:group of larger forms allied to the European C. aeruginosus, wherein a grey See also:dress is less often attained, of which the South See also:African C. ranivorus and the New See also:Zealand C. gouldi are examples.
