other species collect in Tor Bay during the herring and sprat seasons, and at these times they will wait and watch about the harbours and quays in fluttering hosts for the odd fish and offal. The note of this Gull very closely resembles that of the Herring Gull, so closely, in fact, that no symbol can denote the difference. It may be syllabled as klĭ-ou-klĭ-ou, and during the breeding season is very persistently uttered. Owing to its relatively longer wings, this Gull looks more graceful in the air than its larger and heavier congener: its flight is remarkably easy and buoyant, and on occasion rapid.

The usual breeding places of the Lesser Black-backed Gull are low rocky islands—these larger Gulls always prefer an island, covered with coarse marine grass, sea campion, and the like—but in some localities a rock stack, an island in an inland lake, on grassy downs, in mosses, and flows. This Gull usually breeds in colonies, and some of these are very large. One of the most extensive, within the present writer’s experience, is situated on the Farne Islands. The entire group of islands may be regarded as one vast colony of Lesser Black-backed Gulls, if we except a few of the outlying rocks, where the Cormorants breed. It is more than likely that this Gull pairs for life, seeing that it resorts to the same nesting places, year by year, for time out of mind. The nest, even in the same colony, varies a good deal in size and general completeness. Some birds are content merely to line a hollow in the rocks with a little dry grass; others are more bulky yet slovenly structures, rude heaps of turf, heather stems, sea campions, or dry grass and sea-weed, the lining being composed of finer grasses, many of them often semi-green. Occasionally a feather or two are seen, but these may be due more to accident than to design. Few sights in the bird-world are prettier than a colony of disturbed Gulls during the breeding season. As their haunts are invaded, the frightened birds rise in fluttering thousands, drifting to and fro like a snowstorm, in which each flake is a startled bird. The noisy din, the rush of wings, the swooping, soaring, fluttering Gulls, the ground strewn with nests—all combine to form a picture in the mind that time can never efface! The eggs of this Gull are usually three in number, sometimes as many as four. They vary to an almost incredible degree. The ground colour varies from pale green to dark olive-brown and gray, spotted, blotched, or streaked with dark liver-brown, pale brown and gray. Vast numbers of the eggs of this Gull are collected for food, especially at the Farne Islands. The birds do not appear to suffer in any way by this systematic pillage, for they are always allowed to rear a brood from a second clutch at the Farnes, and most rigorously protected whilst doing so.

HERRING-GULL.

Of all the gulls that frequent the British coasts, this, the well-known Larus argentatus (i.e. “silver-winged”), is certainly the most common and widely dispersed. It is no exaggeration to say that the Herring-Gull may be met with on every part of the British coasts, from the Orkney and Shetland Islands on the north, to Cornwall and the Scilly Islands in the south; from the Blasquets in the wild west of Ireland, to the mouth of the Thames and the Bass Rock in the east. It is the Gull par excellence associated in the popular mind with the sea shore—the “Sea Gull” of the visitor to marine resorts, ubiquitous, well-known from the Land’s End to John-o’-Groat’s. For its size, it is certainly the tamest and least suspecting Gull found on British waters. It may be readily recognised, when adult, by the pale grey colour of its mantle, but the young and immature birds are less easily identified. During the non-breeding season it wanders far and wide like the rest of its kind, and is a very frequent visitor to the fields, not only adjoining the sea, but at some distance inland. Whilst tilling operations are in progress, especially in spring, it passes regularly from the coast to the fields, following the plough, or collecting upon the newly-manured pastures, in quest of food. Wild, stormy weather, I have repeatedly noticed, will also drive this Gull landwards sooner, perhaps, than any other species. Like its congeners, it is practically omnivorous. Carrion is sought after as readily as living fish and other marine creatures. I have also known this species regularly to visit a slaughter-house near the coast, to feed upon the offal thrown upon the pastures for manure; and I have repeatedly watched the pure-plumaged birds fighting with the Rooks and Crows for a share of the feast. This Gull will also feed on grain, grubs, and worms, is a constant follower of vessels, and congregates in unusual numbers at fishing harbours during the sprat and herring seasons. In its flight it is graceful in the extreme, and it may often be seen soaring at a vast altitude like a Vulture. Writing on the flight of this Gull, Gätke (in his fascinating work, Heligoland, as an Ornithological Observatory) says: “Not only are these Gulls able to soar in a calm atmosphere in a direction straight forwards, or sideways, on calmly outspread wings, but, as has been more fully discussed in the case of Buzzards, they can also, in a manner similar to theirs, soar upwards to any desirable altitude. The Gulls are able to perform their soaring movements on the same plane in all phases of the weather, during the most violent storm, as well as in a perfect calm, progressing forwards or sideways at the most variable rates of velocity; now darting along with the swiftness of an arrow, now merely gliding, as it were, at the slowest pace imaginable. In the latter case, indeed, we are frequently, even against our will, forced to the conclusion that these birds must have at their command some unknown means or mechanism which prevents their sinking; for neither is the surface-area of their wings large enough, nor are these organs sufficiently concave in form, to allow of their supporting the bird after the manner of a parachute.” I can endorse these remarks fully from my own observations (Conf. Idle Hours with Nature, pp. 261, 262). That these flights are accompanied with any vibratory movements of the feathers is erroneous, as I have had many opportunities of satisfying myself, especially when observing the flight of the Fulmar at St. Kilda, the birds then not being more than six feet away from me, when I am positive every individual feather was in perfect rest.

But to return from this digression to the general habits of the Herring Gull. The breeding season of this Gull is in May and June. Owing to its remarkable aptitude for accommodating itself to the various peculiarities of the coast, it is certainly the most widely dispersed Gull of the British species during the season of reproduction. Perhaps its favourite breeding place is a low rocky island, but failing this it is equally at home upon a range of sea cliffs, a stack of rocks, or less frequently an island in a loch, or, as at Foulshaw Moss in Westmoreland, a marsh. The nest is made on a ledge or in a hollow or chink of the cliffs; in a sheltered hollow of the grassy downs: or amongst the thick growth of sea campion, thrift, and other marine plants that often grow so luxuriantly in the bird’s haunts. I have remarked that the nest is usually larger when built on a cliff than when on the ground, and in some cases is almost dispensed with. It is composed of turf, dry sea-weed, coarse grass, and stalks of various marine plants, lined with finer grass often gathered green. The eggs are two or three in number, varying in ground colour from pale bluish-green through yellowish-brown to olive-brown, and the spots are small and few and dark brown, pale
