is known as the “Ring Dotterel”; in others its local name is the “Sand Lark.” The favourite haunts of the Ringed Plover are the sandy portions of the beach; but in autumn and winter this bird frequently visits mud-flats. The Ringed Plover is about the size of a Thrush, and may be easily recognised by its broad white collar, black breast and cheeks, brown upper parts, and snow-white under parts. Its actions on the shore are most engaging, tripping here and there along the margin of the waves, over the wet sand and shingle, darting this way and that as some tempting morsel of food is discovered. If in autumn or winter, this Plover will generally be met with in flocks of varying size; if in summer in scattered pairs or parties composed of the birds breeding in the immediate neighbourhood. Ringed Plovers are most attached to certain haunts, and seem to frequent them year by year, notwithstanding continued persecution and disturbance. It is the same when they are feeding. If alarmed they usually rise in a compact bunch, fly out to sea a little way, then return inshore, perhaps passing two or three times up and down before finally alighting. Again and again may this action be repeated, although the flock has a tendency to break up if flushed many times in quick succession, and odd birds will fall out, or remain skulking amongst the shingle. A dense flock or bunch of Ringed Plovers is a pretty sight. The birds fly quickly, and wheel and turn with astonishing precision, now close to the waves, then up in the air above the horizon, often persistently uttering their shrill call note, which resembles the syllables too-it rapidly repeated. Occasionally a fair sprinkling of Sanderlings and Dunlins may be observed in the flocks of this species. If seriously alarmed the entire flock will mount up high, and go off to a distant part of the coast, or even divide into several smaller ones, each retiring to a different spot; but almost invariably they return, and reform into a single company on the old familiar sands, within a hour or so of their scattered departure. The food of this pretty little Plover consists of the smaller creatures of the shore, such as minute sand-worms, shrimps, sand-hoppers, tiny molluscs, and insects. That this species occasionally eats vegetable substances I have assured myself by repeated dissection.
Although the Ringed Plover appears only to rear one brood in the year, its laying season is prolonged from the middle of April to the beginning of June. Early in April the winter flocks begin to disband, and the birds to disperse over their breeding places. Many pairs may be found breeding on one large stretch of sand in a suitable district. Some individuals seek an inland site for their eggs, on the bank of a stream or lake, but the majority prefer the sands of the sea-shore. Occasionally the nest has been discovered remote from water. This Plover makes no nest. The eggs sometimes are laid in a hollow of the sand, but just as frequently on the level surface. The fine sand is always preferred to the shingle, as the eggs best harmonize in appearance with it, their fine markings becoming more conspicuous on the coarser surface. The bird sits lightly: indeed it is most exceptional to see one rise from its eggs, unless the spot had been previously marked. When disturbed, the birds exhibit but little outward manifestation of alarm. They may be seen running to and fro about the sand, but their behaviour is very different from that of the Lesser Terns, which often nest on the same sands. The eggs of the Ringed Plover are always four in number, very pyriform in shape, and invariably laid with the pointed ends turned inwards. They are large in proportion to the bird, and pale buff or stone colour sparingly spotted and speckled with blackish-brown and ink-gray. During May and June a smaller and darker race of Ringed Plover passes along our coasts, to breed further north; appearing on the return journey during August, September, and October. There is some evidence to suggest that this race breeds sparingly on the coasts of Kent and Sussex.
This species, the Ægialitis cantiana of ornithologists, is one of the most local of British birds. Stragglers have been obtained here and there along the coast line between Yorkshire and Cornwall, but its only known nesting places are on certain parts of the coasts of Kent and Sussex. It is now nearly a century ago since this Plover was first made known to science by Lewin, who figured it in his Birds of Great Britain; and by Latham, who described and named it in the supplement to his great work, the Index Ornithologicus, from examples which had been obtained on the Kentish shingles by Mr. Boys of Sandwich. The Kentish Plover bears a superficial resemblance to the Ringed Plover, but may readily be distinguished by the broken pectoral band, represented by a dark patch on each side of the breast, and the reddish-brown nape and crown. Unlike the preceding species, this Plover is a summer migrant only to the British coasts, arriving towards the end of April or early in May, and departing again with its young in August or September. Odd birds, however, have been met with during winter. The Kentish Plover does not differ in its habits in any marked degree from the Ringed Plover, and frequents very similar localities, stretches of sand and shingle. Like that bird, it also gathers into small parties during summer; but in our islands, where its numbers are limited, we more usually find it in isolated pairs on various suitable parts of the shore. It possesses the same restless habits; running about the wet shining sands and shingles close to the breaking waves, in quest of the sand-hoppers, crustaceans, worms, and other small marine creatures on which it feeds. It cannot be regarded as a shy bird, permitting a somewhat close approach, and manifesting little fear or alarm even when its breeding grounds are invaded by man. Its alarm note may be described as a shrill ptirr, but the usual call is a clear loud whit, which, during the love season, is frequently uttered so quickly as to form a sort of trill, as the cock bird soars and flies round and round above his mate. The Ringed Plover utters a very similar trill during the pairing season.
The Kentish Plover rears but one brood during the summer, and preparations are made for this towards the end of May. It is not improbable that this Plover pairs for life, seeing that the same localities are visited year by year for nesting purposes. It makes no nest, the eggs being laid in a little hollow amongst the coarser sand or the shingle, or on a drift of dry seaweed and other shore débris. The eggs are usually three, but occasionally four in number, and are pale or dark buff in ground colour, blotched, scratched, and spotted with blackish-brown and slate-gray. As is the almost invariable custom with birds breeding on bare plains and beaches – and whose eggs are protectively coloured – the Kentish Plover sits lightly, rises from her eggs as soon as danger is discovered, and evinces but little outward anxiety for their safety; although, in some instances, the feigning of lameness has been resorted to, especially when the eggs have been on the point of hatching. The young birds and their parents form a family party during the autumn, and apparently migrate southwards in close company.
With the present species we exhaust the number of Limicoline birds that nest upon the shore in the British Islands. All the other species that make our sands and mud-flats their winter home, or their place of call during their spring and autumn migrations, breed away from the actual beach on marshes and moors and uplands, or do not rear their young at all within our area. Closely associated with most of these birds are the fascinating problems of Migration. We miss the feathered hosts from sand and mud-flat as the spring advances; we note the fleeting appearance of others along the shore bound to far away northern haunts: and then long before the first faint signs of autumn are apparent these migrant birds begin to return, and imbue the wild lone slob-lands and shingles with life. To and fro with each recurring spring and autumn, the stream of avine life flows and ebbs; by day and by night the feathery tides press on, calling forth wonder from the least observant, filling more thoughtful minds with the complexity and the mystery of it all. We have not space to deal here with this grand avine movement; but, content with this passing allusion to it, pass on to a study of the other feathered dwellers by the sea.
It is rather remarkable how few species of Limicoline birds breed on the British coast-line. Not a single Sandpiper nor Snipe does so, and but two or three Plovers, as we have already seen. So far as summer is concerned, these wading birds cannot be regarded as a very remarkable feature of avine life upon the coast; and it is, doubtless, because they are so little known to the majority of seaside visitors, that they appeal so much less to the popular mind than the more ubiquitous Gulls. But from September onwards to the following spring, Plovers and Sandpipers are the most prominent characteristics of all the more low-lying coasts. We will briefly glance at those species that not only frequent such situations regularly every season, but occur in sufficient numbers to place them beyond the category of abnormal visitors, or storm-driven wanderers from their natural haunts.
