The Whin-chat (Pratincola rubetra), included in the family Erythacinae or Robins, is closely allied to the Stone-chat (Pratincola or Saxicola rubicola), and, like it, prefers the neighbourhood of furze or whin-bushes, but, unlike it, is a migratory bird, arriving in Britain in the middle or end of April. The upper parts of the body are coloured brown, with a white streak passing across the sides of the head; tail, white and brown at tip; chin, white, and throat fawn; the belly buff. The average length is 4 in. It produces two broods in the year. The nest is constructed on the ground, and the eggs are four to six in number, of a bluish-green hue spotted with brown. The first brood is hatched about the end of May. It feeds on the worms and insects which it procures in the neighbourhood of furze-bushes. The whin-chat, like the wheat-ear, is greatly esteemed for the delicacy of its flesh in the autumn.
