Part 22

The kestrel is easier to tame, and, when tame, more docile and affectionate, than most hawks, and many accounts have appeared in print of the bird and its ways in the domestic condition; but, to my mind, not one so interesting as the history of a pet kestrel kept a few years since by some friends of mine. The bird was young when it came into their hands, and was lovingly cared for, and made free of a large house and park, and of the whole wide country beyond. And it made good use of its liberty. As a rule, every morning it would fly away and disappear from sight until the evening, when, some time before sunset, it would return, dash in at the open door, and perch on some elevated situation--a cornice, or bust, or on the top of a large picture-frame. Invariably at dinner-time it flew to the dining-room, and would then settle on the shoulder of its master or mistress, to be fed with small scraps of meat. This pleasant state of things lasted for about three years, during which time the bird always roosted in, or somewhere near, the house, flew abroad by day, to return faithfully every evening to his loving human friends to be caressed, and fed, and made much of; and it might have continued several years longer, down to the present time, if the bird’s temper had not suffered a mysterious change. All at once, for no reason that anyone could guess, he became subject to the most extraordinary outbreaks of ill-temper, and in such a state he would, on his return from his daily wanderings abroad, violently attack some person in the room. Up till this time he had preferred his master and mistress to any other member of the household, and had shown an equal attachment to both; now he would single out one or other of these his best friends for his most violent attacks; and, very curiously, on the day when he attacked his master he would display the usual affection towards his mistress, but on the next day would reverse the process. And his hostility was not to be despised: rising up into the air to a good height, he would dash down with great force on to the obnoxious person’s head, often inflicting a lacerating blow with his claws. More than once, the lady told me, after one of these cutting, ungrateful blows on her forehead her face was bathed in blood.

It is pleasant to be able to relate that no feeling of resentment or alarm was excited by this behaviour on the part of the bird; that he was never deprived of his sweet liberty or treated with less gentleness than before. It was hoped and believed that he would outgrow the savage fit, and if he had confined his virulent attacks to his master and mistress it would have been well with him. Unfortunately for him, he attacked others who were made of poorer clay. One evening at dinner, the butler, while occupied with his duties, was struck savagely on the wrist by the kestrel. Like a well-trained servant, he did not wince or cry out, but marched stolidly round the table, pouring out wine, anxious only to conceal the blood that trickled from his wounds. But on the following day the bird was missing, and was never afterwards seen or heard of.

Osprey.

Pandion haliaëtus.

Feathers of the head and neck white with dark centres; on each side of the neck a streak of blackish brown, extending downwards; upper plumage generally deep brown; under parts white, tinged here and there with yellow, and on the breast marked with arrow-shaped spots; tail-feathers barred with dusky; cere and beak dark grey; iris yellow. Length, two feet.

The osprey, like the sea-eagle, hen harrier, and kite, is one of the species that linger with us on the verge of extinction; and it may linger for many years, as in the case of the avocet, the black-tailed godwit, and the ruff, after these species had been reduced to a few breeding pairs; and, on the other hand, it may be gone to-morrow. That it will remain permanently as a member of the British avifauna is scarcely to be hoped.

The osprey, like the peregrine falcon and the short-eared owl, has an immense range, and inhabits Europe, Africa, the greater part of Asia, Japan, Formosa, the Australian region, New Guinea, and America. With us it appears in autumn as a migrant in small numbers; but the birds of the British race are now reduced to one or two pairs that breed annually in the Highlands of Scotland, and are strictly protected in their summer haunts.

The osprey feeds exclusively on fish, which it drops upon like a tern or gannet; but, falcon-like, it strikes with its feet, and, with its slippery prey gripped firmly in its sharp, crooked talons, it flies back to land.

The nest is usually placed in a tree, and is very large, formed of sticks, and lined with moss. Two or three eggs are laid, white or buff in ground-colour, blotched with rich chestnut-red, and purple-grey underlying marks.

* * * * *

Besides the twelve species of the order Accipitres described, all of which breed in the British Islands, there are fourteen others, which, although described as British in the standard ornithological works, are only occasional or accidental visitors or stragglers to our shores. There are two vultures to be mentioned: the griffon vulture (_Gyps fulvus_), an inhabitant of Southern Europe, Africa, and Asia, once obtained in Ireland; and the Egyptian vulture (_Neophron percnopterus_), an inhabitant of Southern Europe and Africa, twice obtained. The next species is the marsh-harrier (_Circus æruginosus_), once abundant throughout Great Britain and Ireland, now, unhappily, extinct as a British species. This harrier, which was also called the moor-buzzard, is a graceful, handsome bird: the head creamy white; upper parts brown; beneath, buff, streaked with brown and chestnut; part of the wing and the tail silvery grey. In its buoyant flight and preying and nesting habits it resembles the hen harrier, but frequents fens and marshes instead of moors and uplands.

The rough-legged buzzard (_Archibuteo lagopus_) is an irregular visitor, chiefly in autumn and winter, from the northern parts of Europe. It differs from the common buzzard in having its legs feathered to the toes--hence the specific name, _lagopus_--rough-footed like a hare. This species is of more frequent occurrence in the British Islands than any other occasional visitor among the diurnal raptors, and in some years it appears in considerable numbers.

The spotted eagle (_Aquila clanga_), known to us as a rare occasional visitor, breeds in the forests of central and south-eastern Europe. More interesting to us is the goshawk (_Astur palumbarius_), since this fine bird of prey, although now a very rare straggler to Great Britain, is believed to have been formerly an indigenous species, and to have bred in Scotland down to the beginning of the present century. In form, colouring, and manner of preying it resembles the sparrow-hawk, but is nearly double the size of that bird, and flies at very much larger game.

The American goshawk has been included in the list of British birds on ‘somewhat slight evidence,’ as the author of the ‘Manual of British Birds’ says. The black kite (_Milvus nigrans_) is an African species, a summer visitant to Europe south of the Baltic, and has once been obtained in Great Britain. The swallow-tailed kite (_Elanoïdes furcatus_), an American species, which I once had the pleasure of seeing (not in a glass case, but sitting on a tree, and soaring in the air), has also been found as a straggler in this country. The honey-buzzard (_Pernis apivorus_) is a third species of hawk in this list which has disappeared from this country. Like the hobby and the osprey, it is (or was) a summer visitant, and has been known to breed in most English and Scottish counties from Hampshire to Aberdeenshire. Up to within four or five years ago a few pairs continued to return to us each summer, but these, too, have now vanished. This fine large hawk, in size the equal of the common buzzard, lived almost entirely on insect food, wasps and wild bees especially--hence its name of honey-buzzard.

[Illustration: FIG. 73.--HONEY-BUZZARD. ¹⁄₁₂ natural size.]

The remaining species to be noticed are all true falcons: the gyrfalcon (_Hierofalco gyrfalco_), an inhabitant of arctic Scandinavia, only once obtained in this country; the Greenland falcon (_Hierofalco candicans_), a wanderer to this country from north-west America and Greenland; the Iceland falcon (_Hierofalco islandicus_), a wanderer from Iceland; the red-footed falcon (_Tinnunculus vespertinus_), an occasional visitor from the warm countries of Europe; and the lesser kestrel (_Tinnunculus cenchris_), a visitor from southern Europe, where it breeds.

Cormorant.

Phalacrocorax carbo.

[Illustration: FIG. 74.--CORMORANT. ¹⁄₁₁ natural size.]

Upper head and neck black, striated with hair-like white feathers, those on the occiput being elongated, and forming a crest in spring; throat white; gular pouch yellow; mantle black and bronze-brown; all the other parts black, except a white patch on the thigh, assumed early in spring and lost in summer; iris emerald-green. _Female_: larger than the male, brighter in colour, and with longer crest. Length, three feet.

* * * * *

To those who know it slightly the cormorant is a big, sombre, ugly bird, heavy and awkward in his motions out of the water, and, when breeding, disgusting in his habits. He improves on a closer acquaintance. He may be easily tamed, and makes an intelligent, and sometimes very amusing, pet, and is capable of being trained to catch fish for his keeper. He is most frequently met with on the sea and seashore, but is an inhabitant of inland waters as well, and sometimes breeds beside them, making his nest on the ground or in a tree. He feeds exclusively on fishes and eels, which he captures by diving and pursuing them under water, sometimes for considerable distances. The bird is proverbial for its voracity. Its ‘swallow’ is probably the largest of any bird of its size--a fish fourteen inches long has been taken from its gullet. When swimming he presents a curious appearance: his body, as if too heavy for the element it floats in, sinks like a waterlogged boat, until the flat back is on a level with the surface. When alarmed, he sinks his body deeper and deeper at will, until the head and long neck alone appear, looking like the head and neck of a serpent swimming with body submerged. When resting on a rock after feeding, cormorants stand very erect and motionless, their long, hooked beaks much raised, and at such tunes they present a heavy, ungainly appearance. They are fond of opening their wings out to their greatest extent to dry their feathers, and remain for a long time in this attitude, looking like birds with spread wings carved out of black stone. The cormorant watches the water at times from a rock, and dives after its prey; but it more often swims, when fishing, with head and neck submerged. When taking wing it rises heavily and with great labour, but when once fairly launched the flight is powerful. Cormorants are gregarious and social birds at all seasons, and, like gulls and herons, they breed in communities. Very early in spring, or shortly after the winter solstice, the bird’s nuptial ornaments--a crest on the head and a white patch on the thigh--begin to appear; both crest and white mark disappear at the end of the breeding season. The same nesting-place is resorted to year after year, as in the case of most species that breed in communities. The summit of a crag not easily accessible, or a ledge of rock on a cliff fronting the sea, or a rocky island, are favourite sites. Here the birds, sometimes in hundreds, live together in the greatest harmony, building their nests close together, in some cases almost touching. The nest is pyramidal in form, built up from the rock to a height of from six or seven inches to a couple of feet, and is composed of sticks, coarse grass, and seaweed. Three to five eggs are laid, very small for the bird’s size, narrow and long in shape, of a pale greenish blue colour, overlaid with a thick coat of a chalky substance. This substance is quite soft when the egg is first laid; it is then white, but soon hardens, and becomes stained, in the always wet and filthy nest, to a dirty yellowish colour. The young birds are hatched blind, and have a naked, bluish black skin, but they soon grow a thick, sooty black down. They are at all stages strange and repulsive-looking creatures, and when handled or approached by a person they become sick with fear or anger, and roll and sprawl about on their nests, screaming harshly, and vomiting their half-digested food.

The young are fed with fish that has already been partially digested in the maw of the parent. It is not disgorged; the young bird thrusts his head and neck deep down into his parent’s gullet, and feeds as a horse does from his nose-bag.

The young are said not to assume the adult or breeding plumage until the third year.

Shag, or Green Cormorant.

Phalacrocorax graculus.

Bill black; base of the under mandible yellow, the black skin about the gape thickly studded with small yellow spots; iris emerald-green; crown, neck, upper and under parts dark green with purple and bronze reflections; wing and tail-feathers, legs and feet, black; a crest, curling forwards, grows on the forehead in early spring, and is lost by the end of May. Length, twenty-seven inches.

* * * * *

The shag may be easily mistaken for the cormorant, which it closely resembles, but when near at hand is seen to differ in its smaller size and its prevailing green colour, which appears black at a distance; and, in the breeding season, by the absence of the white patch on the flank. In its habits it is more strictly marine than the cormorant, but resembles that bird in its manner of swimming and flight. It prefers bays and inlets to the open sea, and deep water near rocks to the shallow sea, where there is a low beach. In diving after fish it springs upwards almost out of the water, and goes down head first. Beneath the water it propels itself wholly by its feet; the auks, and some other diving birds, use their wings as fins to assist progression. After capturing a fish the shag brings it to the surface to swallow it, then swims on for a space, and dives again, and so on, and finally returns to the rock, where it proceeds to disgorge its prey, to devour it at leisure. The shag breeds on sea-cliffs, sometimes building on the ledges or in crevices, but caves, where they exist, are preferred. The eggs are three in number, in shape and colour like those of the cormorant, and the nests, which are placed close together, are also like those of that bird.

The shag is found in certain localities all round the coasts of Great Britain and Ireland, but is less numerous and more local than the cormorant.

Gannet.

Sula bassana.

Adult: head and neck buff-colour; all the rest of the plumage white, except the primaries, which are black. Young of the first year: upper parts blackish brown necked with white; under parts mottled with dusky ash and buff. The dark markings diminish until the sixth year, when the adult colouring is assumed. Length, thirty-four inches.

* * * * *

One of the most notable seafowls inhabiting the British coasts is the gannet, or solan goose, a species which forms a connecting-link between the cormorants and the pelicans. The origin of its two common names is not precisely known, although it seems probable that gannet is derived from _gans_, the ancient British name for goose. The young birds from the Bass Rock, which are largely used as food in the neighbouring counties, are called, I do not know why, ‘Parliamentary geese.’ The world will have it that the bird is a goose, although as little like a goose, except in size, as a guillemot is like a sheldrake. The scientific name, _bassana_ (of the Bass Rock), had its origin in the belief that the rock at the entrance to the Firth of Forth was the gannet’s only breeding-place. There are several other colonies: one, now greatly diminished, on Lundy Island; another, also small, on the coast of Pembrokeshire; on the West Coast of Scotland there are four stations, and others exist on the Irish coast. None of these, however, can compare in importance with the Bass Rock, where it has been calculated that as many as ten thousand pairs congregate each year to breed.

The gannet is an exclusively marine bird, and an inhabitant throughout the year of the seas round the British Islands. Its flight is easy and powerful, and its appearance on the wing more pelican- than cormorant-like. It feeds entirely on fish, and follows the shoals of such species as swim near the surface--mackerel, herrings, pilchards, and sprats. When fishing it sails at a considerable height, and on catching sight of its prey rises to a greater height, and then, with wings nearly closed, drops straight down, with great force, into the water. Its appearance when falling has been likened by one observer to ‘a brilliant piece of white marble.’

The gannets begin to assemble at the breeding-rock in March. Their nesting habits are similar to those of the cormorant, but only one egg is laid, which is, like the cormorant’s egg, pale blue in colour and thickly coated with a white, chalky material. Mr. Charles Dixon, in ‘Our Rarer Birds,’ thus describes a visit to the great gannet settlement on the east coast: ‘By far the best locality for studying the nesting economy of the gannet is the Bass, that wide-famed mass of basaltic rocks standing like a sentinel in the Firth of Forth.... Upon reaching the Bass a few gannets may be seen sailing dreamily about, but you have no idea of the immense numbers until you have climbed the rugged hill.... But when the summit of the cliff is reached the scene that bursts upon our gaze is one that well-nigh baffles all description. Thousands upon thousands of gannets fill the air, just like heavy snowflakes, and on every side their loud, harsh cries of “carra-carra-carra” echo and re-echo among the rocks. The gannets take very little notice of our approach, many birds allowing themselves to be actually pushed from their nests. Others utter harsh notes, and with flapping wings offer some show of resistance, only taking wing when absolutely compelled to do so, and disgorging one or two half-digested fish as they fall lightly over the cliffs into the air. On all sides facing the sea gannets may be seen. Some are standing on the short grass on the edge of the cliffs, fast asleep, with their heads buried under their dorsal plumage; others are preening their feathers; whilst many are quarrelling and fighting over standing-room on the rocks.’

Describing another great breeding-place of the gannet on the island of Borreay, about four miles from St. Kilda, he says: ‘The flat, sloping top of one of these stupendous ocean rocks, called by the natives “Stack-a-lie,” looks white as the driven snow, so thickly do the gannets cluster there, and the sides are just as densely populated wherever the cliff is rugged and broken. So vast is this colony of birds that it may be seen distinctly forty miles away, looking like some huge vessel under full sail heading to windward.’

Heron

Ardea cinerea.

Crest bluish black; upper parts slate-grey; forehead, cheeks, and neck white, the latter streaked with bluish grey and terminating in long white feathers; under parts greyish white; bill yellow. Length, thirty-six inches.

The heron is sometimes spoken of as our largest wild bird. It is not meant that he is really larger than the golden eagle, or wild swan, or grey lag goose, but only that he is the biggest of the comparatively common birds. The heron has two very different aspects--when in repose, or standing, and when on the wing. On the ground, or, as we more often see him, standing knee-deep in the water, watching the surface, he presents a sorry appearance--a bird lean and ungraceful in figure, white and ghostly grey in colour, awkward in his motions when he moves. No sooner does he open his wings than this mean aspect vanishes, and he is transfigured. At first the flight appears heavy on account of the slow, measured beats of the broad, rounded vans; but as he rises higher, and soars away to a distance, it strikes the beholder as wonderfully free and powerful. The appearance of the bird is then majestic, and its flight more beautiful than that of any other large wading bird with which I am acquainted--ibis, wood-ibis, stork, flamingo, or spoonbill. When pursued by a falcon the heron is capable of rising vertically to a vast height, while the hawk rushes after in a zigzag course, striving to rise above his quarry so as to strike. This aërial contest of hawk and heron forms a very fascinating spectacle, and formerly, when falcons were trained for this sport, the heron was as much esteemed as the pheasant--which has been called the ‘sacred bird’--is at the present day. With the decline of falconry the heron ceased to be protected by law, and diminished greatly in numbers; but he is an historical bird, and there is a feeling, or sentiment, that has served to prevent his extermination. It is still considered a fine thing to have a heronry on a large estate; and so long as this feeling endures the bird will receive sufficient protection, although the existing heronries, when we come to count them, are not many.

The heron breeds in communities, and when the heronry is well-placed and safeguarded the birds return to it year after year. As a rule the nests are built on the tops of large trees in a sheltered part of the wood. The nest is a bulky, rudely built platform structure of sticks and weeds, lined with rushes, wool, and other soft materials. Three or four eggs are laid, very pale dull green in colour. The young are fed in the nest five or six weeks before they fly. Two broods are reared in the season.
