[Illustration: GOLDEN PLOVER _Charadrius pluvialis_ (left) GREY PLOVER _Squatarola helvetica_ (right)] GREY PLOVER Squatarola helvetica (Linnæus) Very similar to the Golden Plover in general appearance, but the yellow spots are replaced by whitish, and the hind toe is lacking. A few weeks in spring and autumn along the shore is all the time this bird spends with us; he passes the winter in the warm tropics of Africa, wandering southwards as far as the Cape, and then, obeying some mysterious impulse of which we can form no conception, he journeys in May northwards, and passing over many spots, which would to our ignorant eyes afford him food and shelter sufficient for the rearing of his young, he seeks out the wild and lonely tundras of Europe and Siberia. There during the eternal day of an Arctic summer he rears his family, and as soon as they can fly, old and young are back again on our shores. For some weeks they remain, slowly passing to the south, and, unlike the Golden Plover, rarely coming inland; but by the middle of October they are all back enjoying once more the burning sun of the tropics. The white tail coverts and absence of the hind toe will prevent any confusion between this species and the Golden Plover. Length 11·5 in.; wing 7·75 in. THE SOCIABLE PLOVER Vanellus gregarius (Pallas) This species is a native of South Russia and the Aralo-Caspian area. Until a few months ago, when a second example was procured in Kent, it had only once (in 1860) been taken in England. The general colour above is drab; crown of the head black, margined with white. Quills black; secondaries white; tail white, with a subterminal brown band. Chin white; throat buff; breast brown; belly black; flanks and under tail coverts deep chestnut. Length 12 in.; wing 8 in. THE LAPWING Vanellus vulgaris, Bechstein No wild bird has perhaps to pay so large a tribute in eggs and individuals to man, and yet remains as common and abundant, as the Lapwing. Early in March he appears on the marsh or water-meadows, where he or his parents before him have been accustomed to spend the summer; sometimes dry fields at some distance from the water are chosen, but as a rule it is never far from a river, stream, or even a moderate-sized pond. Although many pairs often nest in the same field, fierce battles take place between the males for the mates of their choice, but there is more “show” than strife, lengthy aerial chases with much calling out but very little serious fighting. Once, however, these early difficulties have been overcome, the colony settles down in peace, a few ousted pairs being left to seek some fresh ground.
