When anxious to avoid being seen the stone-curlew practises the device of squatting close on the ground with its neck extended. The South American rheas have a similar habit, and it is, perhaps, possessed by other large birds that have a more or less protective colouring and inhabit the open country.
The stone-curlew feeds on slugs, worms, and insects, and also devours mice and small reptiles.
The family Glareolidæ is represented in works on British birds by one species, the collared pratincole (Glareola pratincola), a rare straggler to Great Britain from Southern Europe. This bird comes between the stone-curlew and the true plovers (family Charadriidæ), which follow.
The cream-coloured courser (Cursorius gallicus) is another rare straggler to England from Western Asia and North Africa.
Golden Plover.
Charadrius pluvialis.
Upper parts greyish black spotted with gamboge-yellow; above the eye a white line, which continues down the neck to the flanks; under parts black. After the autumnal moult the under parts are white, and the upper parts more yellow than in spring. The female, in summer, has less black on the breast. Length, eleven inches.
The golden plover has for several centuries been in great esteem for the table, its fame in this respect being equal to that of the dotterel, woodcock, ruff, and black-tailed godwit. The two last named have now ceased to exist in this country as breeding species. The golden plover, although incessantly persecuted by fowlers and sportsmen, is still not uncommon; probably because the great majority of the birds that visit the British islands on migration in autumn and winter have their breeding-grounds in remote regions north of the arctic circle, where there are no human beings to molest them. The birds that breed with us are also migratory, and escape destruction by going south in autumn.
