British Birds in Their Haunts

by C. A. Johns

Summer—head and upper part of the neck deep brown; lower part of the neck and all the under plumage white, slightly tinged with rose; upper plumage bluish ash; primaries white, edged with ash, and broadly tipped with black; irides brown; bill and feet red, with a purple tinge. In winter the head and neck are white; bill and feet bright vermilion. In young birds the hood is pale brown; the upper plumage dark brown, mottled at the edges of the feathers with yellowish; bill livid at the base, the tip black; feet yellowish. Length seventeen inches. Eggs olive, spotted with brown and dusky.

Black-headed, Blackcap, Brown-headed, Red-legged, and Pewit, are all common distinctive names of this Gull, to which may be added that of Laughing Gull. The latter name is, indeed, often given to the next species, a rare bird, and might with equal propriety be applied to several other species, whose harsh cry resembles a laugh. The systematic name, ridibundus, which has the same meaning, is by general consent confined to this. The reader, therefore, must bear in mind that though the term ridibundus will bear no translation but 'laughing', the name of the Laughing Gull is Larus atricapilla, which can mean only 'Black-headed Gull'; a paradoxical statement, perhaps, but one which it is necessary to make, or the young student will probably fall into error.

Brown-headed Gull is the most appropriate of all the above names, at least in summer, for at this period both male and female are best distinguished by the deep brown colour of the head and upper part of the neck.

This is one of the most frequent of the Gulls, to be sought for in the breeding season not on the rocky shore among cliffs, but on low flat salt marshes on the coast and in fresh-water marshes far inland. Early in spring large numbers of Brown-headed Gulls repair to their traditional breeding-grounds and wander over the adjoining country in search of food, which consists of worms and grubs. From the assiduity with which they resort to arable land and follow the plough, they have been called Sea Crows. In April and May they make their simple preparations for laying their eggs by trampling down the broken tops of reeds and sedges, and so forming a slight concavity. The number of eggs in each nest is generally three, and as a large number of birds often resort to the same spot, the collecting of these eggs becomes an occupation of importance. By some persons they are considered a delicacy, and, with the eggs of the Redshank, are substituted for Plovers' eggs; but to a fastidious palate they are not acceptable, and far inferior to an egg from the poultry yard. Willughby describes a colony of Blackcaps on a small island in a marsh or fish pond, in the county of Stafford, distant at least thirty miles from the sea. He says that when the young birds had attained their full size, it was the custom to drive them from the island into nets disposed along the shore of the lake. The captured birds were fattened on meat and garbage, and sold for about fourpence or fivepence each (a goodly price in those days, 1676). The average number captured every year was 1200, returning to the proprietor an income of about £15. In The Catalogue of Norfolk and Suffolk Birds, it is stated that precisely the same sum is paid for the privilege of collecting the eggs from Scoulton Mere, in Norfolk. Towards the end of July, when the young are fully fledged, all the birds, old and young, repair to the sea, and scatter themselves in small flocks to all parts of the coast, preferring a low sandy shore, or the mouth of a tidal river, as the Thames and the Clyde, where they are of common occurrence. They also accompany shoals of herrings and other small fish, often congregating with other species in countless numbers.

Before winter the distinctive character afforded by the brown plumage of the head and neck has entirely disappeared. These parts are now of a pure white, and the red legs afford the best distinguishing feature. Persons residing on the coast, who are familiarly acquainted with the habits of the bird, but are unaware of the periodical change in its colour, consider the two forms of the bird as distinct species. Thus I have received from a marsh on the coast of Norfolk the eggs of the 'Black-Headed Gull', and have had the same bird pointed out to me in winter as the 'Red-legged Pigeon-Mow' (Mew). One flock of about thirty thus pointed out to me presented a very pretty sight. They had detected either a shoal of small fishes, or a collection of dead animal matter floating among the breakers, and were feeding with singular activity.

THE COMMON GULL
LARUS CÁNUS

In spring the head and neck of this species are white and the mantle is a pale grey, a little darker in summer, the head, tail and under parts white; primaries comparatively long, and the three outer pairs dull black on the lower portions, with large white 'mirrors' near the tips in mature birds—in the rest the predominant tone is a pale grey, the black only forming a bar, and all but the first primary broadly tipped with white; bill a rich yellow towards the point; legs and feet greenish yellow in summer, darker in winter. In winter the head and neck are streaked and spotted with ash-brown. Length eighteen inches.

This is a species resident in Great Britain, but it is not known to breed south of the Solway. It nests, however, in the west of Ireland; grassy sides and islands of lochs or slopes that face the sea, not far often above high-water, are its favourite resorts, where it breeds in colonies, the nest of sea-weeds, heather and dry grass being fairly large. In it will be, as a rule, three eggs, an olive-brown, spotted and streaked with a blackish tone; but pale blue, light green and straw-coloured varieties are found often. This Gull is the first to seek the shore on the approach of 'coarse' weather; and it may often be studied in the fields as it picks up grubs among the furrows in the company of Rooks, or by the town-tied Cockney, from his own standpoint of Westminster Bridge.

The 'Blue Maa', as this species is called in the north, breeds in abundance on the Scottish coasts as well as the moors of the fresh-water lochs, including the Hebrides, Orkneys and Shetlands. The Black-Headed Gull is generally the Common Gull of the peasantry in Ireland, but the underside of the wing in the young of the Common Gull is mottled with brown, whereas it is greyish-white in the Black-Headed species.
