FAMILY FALCONIDÆ

Sub-Family BUTEONINÆ

MARSH HARRIER
CIRCUS ÆRUGINOSUS

Head, neck, and breast yellowish white, with numerous longitudinal brown streaks; wing-coverts reddish brown; primary quills white at the base, the rest black; tail and secondaries ash-grey; lower plumage reddish brown; beak bluish black; cere, irides, and feet yellow; claws black. Length twenty inches. Eggs white.

The Harriers are bold predatory voracious birds, having somewhat of the appearance and movements of the Hawks. On a closer inspection, however, they are seen to approach nearer in character to the Owls. In the first place, they hunt their prey more in the morning and evening than at any other time of day. In the next place, these twilight habits are associated with a large head, and a somewhat defined face formed by a circle of short feathers; while the plumage generally is soft and loose, and their mode of hunting resembles that of the nocturnal predatory birds, rather than that of the Falcons. They are remarkable for the great difference which exists between the plumage of the two sexes, which has made the task of discriminating the number of species very difficult. Less active than the Falcons, they yet carry on a formidable war against small birds, reptiles, and mice. The Harriers or Harrows are so called from their harrying propensities. Of similar import is the etymology of the English word 'havoc', which may be clearly traced to the Anglo-Saxon hafoc, or hawk. The habit of the Marsh Harrier is not to station itself on a tree or rock, thereon to explore the country; but while hunting, it is always on the wing, skimming along the ground, and beating about the bushes with a noiseless, unsteady flight, and always taking its prey on the ground. Rabbit-warrens afford this bird a favourite hunting-ground, where it either pounces on such living animals as it can surprise, or performs the office of undertaker to the dead bodies of rabbits killed by the weasels, burying them in the grave of its craw. In this ignoble office it is said to be sometimes assisted by the Buzzard, and both birds have been accused of setting to work before their unhappy victim has breathed its last. On the sea-shore, the Marsh Harrier commits great depredations among young water-fowl, and is often mobbed and driven from the neighbourhood by the assembled old birds. The Partridge and Quail often, too, fall victims to its voracity, so that the Marsh Harrier receives no quarter from gamekeepers. It places its nest generally near water, in a tuft of rushes, or at the base of a bush, constructing it of sticks, rushes, and long grass, and lays three or four eggs.

The Marsh Harrier is a widely dispersed species, being found, says Temminck, in all countries where there are marshes. It occurs now but sparingly in most parts of Great Britain and Ireland. It is better known as the Moor Buzzard.

HEN HARRIER
CIRCUS CYÁNEUS

Tail longer than the wings; third and fourth primaries of equal length; upper plumage of the male bluish grey; lower white. Upper plumage of the female reddish brown; lower, pale reddish yellow, with deep orange brown longitudinal streaks and spots. Beak black; cere greenish yellow; irides reddish brown; feet yellow; claws black. Length, male, eighteen inches; female, twenty inches. Eggs white.

The Hen Harrier and Ringtail were formerly considered distinct species; and no wonder; for not only are they different in size, but dissimilar in colour, one having the upper parts grey, the lower white; and the other the upper parts reddish brown, and various parts of the plumage of a light colour, barred and streaked with deep brown. The experienced ornithologist, Montagu, suspecting that they were male and female of the same species, undertook to clear up the matter by rearing a brood taken from the same nest. The result was that at first there was no great difference except in size, all having the dark plumage of the Hen Harrier; but after the first moult, the males assumed the grey and white plumage, while the larger birds, the females, retained the gayer colouring, and the latter was the Ringtail. In habits both birds resemble the Marsh Harrier, but do not confine themselves to damp places. They frequent open plains, hillsides, and inclosed fields, hunting a few feet above the surface of the ground, and beating for game as skilfully as a well-trained spaniel. The moment that the Harrier sees a probable victim he rises to a height of twenty feet, hovers for a moment, and then comes down with unerring aim on his prey, striking dead with a single blow, Partridge or Pheasant, Grouse or Blackcock, and showing strength not to be expected from his light figure, and slender, though sharp talons. Not unfrequently he accompanies the sportsman, keeping carefully out of shot, and pouncing on the birds, killing them, and carrying them off to be devoured in retirement. He preys exclusively on animals killed by himself, destroying a great quantity of game small mammals, birds and reptiles. It is a generally-diffused bird, by no means so common as the Kestrel and Sparrow-hawk, but is met with occasionally in most countries of Europe and Asia, and in various parts of the British Isles. It is far from improbable that this bird may frequently be seen, without being recognized as belonging to the Hawk tribe; indeed, the beautiful form and light blue and white plumage, might cause it to be mistaken for a Gull. It builds a flattish nest of sticks, just raised above the round, in a heather, or furze-bush, and lays four to six eggs.
