Part 59

On the coast of Norfolk, where I made my first acquaintance with this bird in the fresh state, it is called a Half-Curlew. In like manner, a Wigeon is called a Half-Duck. In either case the reason for giving the name is, that the smaller bird possesses half the market value of the larger. It resembles the Curlew in its flight and the colour of its plumage; but differs in having its long beak slightly curved upwards, while that of the Curlew is strongly arched downwards; and it is far less wary, allowing itself to be approached so closely that it falls an easy prey to the fowler. It appears to be most frequently met with in spring and autumn, when it visits many parts of the coast in small flocks. In Norfolk it is met with from May, the twelfth of that month being called 'Godwit day,' by the gunners, although it is almost unknown up north at that season.

The specimens which were brought to me were shot in the very severe weather which ushered in the year 1861. These birds have nowhere been observed in England later than the beginning of summer, from which fact the inference is fairly drawn that they do not breed in this country. Their habits differ in no material respects from the other sea-side Waders, with whom they frequently mingle while feeding, not, seemingly, for the sake of good fellowship, but attracted by a motive common to all, that of picking up food wherever an abundance is to be met with. Their note is a loud, shrill cry, often uttered while on the wing. The female is much larger than the male.

This bird is sometimes called the Sea Woodcock. Its flesh is good eating, but is far inferior in flavour to that of the true Woodcock.

THE BLACK-TAILED GODWIT LIMÓSA BELGICA

Beak nearly straight; middle claw long and serrated; upper parts ash-brown, the shafts of the feathers somewhat deeper; breast and adjacent parts greyish white; tail black, the base, and the tips of the two middle feathers, white; beak orange at the base, black at the point; feet dusky. Summer--much of the plumage tinged with red. Length seventeen and a half inches. Eggs deep olive, spotted with light brown.

This bird is, in outward appearance, mainly distinguished from the preceding by having two-thirds of the tail black, instead of being barred throughout with white and black. Like its congener, it is most frequently seen in autumn and spring, while on the way to and from its breeding-ground in the north; but it does not stay with us through winter, though occasionally a few pairs used to remain in the fen-countries to breed. It is by far the less common of the two, and seems to be getting annually more and more rare. Its habits, as far as they have been observed, approach those of the other Scolopacidæ. In its flight it resembles the Redshank. Its note is a wild screaming whistle, which it utters while on the wing. It builds its nest in swamps, among rushes and sedges, simply collecting a few grasses and roots into any convenient hole, and there it lays four eggs.

THE COMMON CURLEW NUMENIUS ARQUATA

General plumage reddish ash, mottled with dusky spots; belly white, with longitudinal dusky spots; feathers of the back and scapulars black, bordered with rust-red; tail white, with dark brown transverse bars; upper mandible dusky; lower, flesh-colour; irides brown; feet bluish grey. Length varying from twenty-two to twenty-eight inches. Eggs olive-green, blotched and spotted with brown and dark green.

Dwellers by the sea-side--especially where the tide retires to a great distance leaving a wide expanse of muddy sand, or on the banks of a tidal river where the receding water lays bare extensive banks of soft ooze--are most probably quite familiar with the note of the Curlew, however ignorant they may be of the form or name of the bird from which it proceeds. A loud whistle of two syllables, which may be heard for more than a mile, bearing a not over-fanciful resemblance to the name of the bird, answered by a similar cry, mellowed by distance into a pleasant sound--wild, but in perfect harmony with the character of the scene--announces the fact that a party of Curlews have discovered that the ebb-tide is well advanced, and that their feeding-ground is uncovered. The stroller, if quietly disposed, may chance to get a sight of the birds themselves as they arrive in small flocks from the inland meadows; and though they will probably be too cautious to venture within an unsafe distance, they will most likely come quite close enough to be discriminated. Not the merest novice could mistake them for Gulls; for not only is their flight of a different character, but the bill, which is thick enough to be distinguished at a considerable distance, is disproportionately long, and is curved to a remarkable degree. Curlews are in the habit of selecting as their feeding-ground those portions of the shore which most abound in worms and small crustaceous animals; these they either pick up and, as it were, coax from the tip to the base of the beak, or, thrusting their long bills into the mud, draw out the worms, which they dispose of in like manner. When the sands or ooze are covered, they withdraw from the shore, and either retire to the adjoining marshes or pools, or pace about the meadows, picking up worms, snails, and insects. Hay-fields, before the grass is cut, are favourite resorts, especially in the North; and, in districts where there are meadows adjoining an estuary, they are in the habit of changing the one for the other at every ebb and flow of the tide. From the middle of autumn till the early spring Curlews are, for the most part, sea-side birds, frequenting, more or less, all the coast; but at the approach of the breeding season they repair inland, and resort to heaths, damp meadows, and barren hills. Here a shallow nest is made on the ground, composed of bents, rushes, and twigs of heath, loosely put together. The eggs, which are very large, are four in number. During the period of incubation the male keeps about the neighbourhood, but is scarcely less wary than at other seasons. The female, if disturbed, endeavours to lure away the intruder from her dwelling by the artifice, common in the tribe, of pretending to be disabled; and great anxiety is shown by both male and female if any one approaches the spot where the young lie concealed. The latter are able to run almost immediately after they are hatched, but some weeks elapse before they are fledged. It seems probable that an unusually long time elapses before they attain their full size, for the dimensions of different individuals vary to a remarkable degree. Eight or nine specimens were brought to me in Norfolk in the winter of 1861, and among them about half seemed full-grown; of the others some were so small that, at the first glance, I supposed them to be Whimbrels.

The Curlew is found on the sea-coast over the whole of Europe and Asia, and along the northern coast of Africa.

The flesh of this bird is said by some to be excellent eating. This, perhaps, may be the case with young birds shot early in autumn before they have been long subjected to a marine diet. My own experience of birds shot in winter does not confirm this opinion. I have found them eatable, but not palatable.

THE WHIMBREL NUMENIUS PHÆOPUS

General plumage pale ash-colour, mottled with white and dusky spots; crown divided by a longitudinal streak of yellowish white; over each eye a broader brown streak; belly and abdomen white, with a few dusky spots on the flanks; feathers on the back, and scapulars deep brown, in the middle bordered by lighter brown; rump white; tail ash-brown, barred obliquely with dark brown; bill dusky, reddish at the base; irides brown; feet lead-colour. Length not exceeding seventeen inches. Eggs dark olive-brown, blotched with dusky.

Though by no means a rare bird, the Whimbrel is of far less common occurrence than the Curlew, and is seen only at two periods of the year, in May and August, when performing its migrations. It resembles the Curlew both in figure and habits, though much smaller in size; its note, too, is like the whistle of that bird, but somewhat higher. It is gregarious, but unsociable with other birds. The extreme southern limit at which the Whimbrel breeds is considered to be the Orkney and Shetland Islands. It is known to visit most of the countries of Europe and Asia in spring and autumn, but is nowhere very abundant.

SUB-FAMILY STERNINÆ

THE BLACK TERN HYDROCHELIDON NIGRA

Bill black; feet purple-brown, the membrane short; head and neck black; upper parts lead-colour; under parts dark ash-grey; under tail-coverts white; tail not much forked, shorter than the wings; irides brown. In winter, the lore, throat and breast are white. Length ten and a quarter inches. Eggs dark olive-brown, blotched and spotted with black.

The Black Tern is a common bird in most temperate countries which abound in extensive marshes. In its habits it is scarcely less aquatic than the preceding species, but differs from them all in preferring fresh water to salt. It was formerly of frequent occurrence in England; but draining and reclaiming have, within the last few years, given over many of its haunts to the Partridge and Wood Pigeon; and it is now but rarely known to breed in this country. A few, however, are not unfrequently seen in spring and autumn, when on their way from and to their winter quarters, which are the warmer regions of the globe. In Norfolk its name still lingers as the 'Blue Darr', a corruption, probably, of Dorr-Hawk (another name of the Nightjar), a bird which it closely resembles in its mode of flight. Like the Dorr-Hawk, the Black Tern feeds on beetles and other insects, which it catches on the wing, but adds to its dietary small fresh-water fish, which it catches by dipping for them. While in pursuit of its winged prey, it does not confine itself to the water, but skims over the marsh and adjoining meadows, sometimes even alighting for an instant to pick up a worm. Black Terns are sociable birds among themselves, but do not consort with other species. They lay their eggs in the most inaccessible swamps, on masses of decayed reeds and flags, but little elevated above the level of the water. The nests are merely depressions in the lumps of vegetable substance, and usually contain three or sometimes four eggs. They are placed near enough to each other to form colonies; and the birds continue to flock together during their absence in warmer climates. Large flocks have been seen in the Atlantic, midway between Europe and America. In Holland and Hungary they are said by Temminck to be numerous. This author states that the Black Tern commonly lays its eggs on the leaves of the water-lily.

The Rev. R. Lubbock states in his Fauna of Norfolk, 1845, that it has ceased to breed regularly in Norfolk, but that eggs had been recently obtained at Crowland Wash in Lincolnshire.

THE SANDWICH TERN STERNA CANTIACA

Bill long, black, the tip yellowish; tarsus short (one inch); tail long; head and crest as in the last; nape, upper part of the back, and all the lower parts brilliant white, tinged on the breast with rose; back and wings pale ash-grey; quills deeper grey; tail white; feet black, yellowish beneath. Young birds--head mottled with black and white; back, wing-coverts, and tail-feathers varied with irregular lines of black; bill and feet dark brown. Length eighteen inches. Eggs greyish green, blotched with brown and black.

The Sandwich Tern, which takes its name from the place where it was first seen in England, is not uncommon on many parts of the coast during the summer months. In some places it seems to be abundant. A large colony inhabits the Farne Islands. They breed as far north as the Findhorn. Upon this coast it is called par excellence 'The Tern', all the other species passing under the general name of 'Sea Swallows'. Its habits are so like those of the Common Tern, to be described hereafter, that, to avoid repetition, I purposely omit all account of its mode of fishing, and content myself with quoting, on the authority of Audubon and Meyer, incidents in its biography which I have not noticed in the Common Tern. The former author says: 'Its cries are sharp, grating, and loud enough to be heard at the distance of half a mile. They are repeated at intervals while it is travelling, and kept up incessantly when one intrudes upon it in its breeding-ground, on which occasion it sails and dashes over your head, chiding you with angry notes, more disagreeable than pleasant to your ear.' Meyer, writing of the same bird, says: 'The Sandwich Tern is observed to be particularly fond of settling on sunken rocks where the waves run high, and the surf is heavy: this being a peculiar fancy belonging to this species, it is sometimes called by the name of Surf Tern.'

THE ROSEATE TERN STERNA DOUGALLI

Bill black, red at the base; feet orange, claws small, black; tarsus three-quarters of an inch long; tail much forked, much longer than the wings; upper part of the head and nape black; rest of the upper plumage pale ash-grey; tail white, the outer feathers very long and pointed; cheeks and under plumage white, tinged on the breast and belly with rose. Length fifteen to seventeen inches. Eggs yellowish stone-colour, spotted and speckled with ash-grey and brown.

Of this Tern Dr. M'Dougall, its discoverer, says, 'It is of light and very elegant figure, differing from the Common Tern in the size, length, colour, and curvature of the bill; in the comparative shortness of the wing in proportion to the tail, in the purity of the whiteness of the tail, and the peculiar conformation and extraordinary length of the lateral feathers. It also differs from that bird in the hazel-colour and size of the legs and feet.'

Roseate Terns have been discovered on several parts of the coast, principally in the north, as in the mouth of the Clyde, Lancashire and the Farne Islands. They associate with the Common Terns, but are far less numerous. Selby says, 'the old birds are easily recognized amidst hundreds of the other species by their peculiar and buoyant flight, long tail, and note, which may be expressed by the word crake, uttered in a hoarse grating key.' They rarely nest in Great Britain.
