The blue rock-thrush feeds on a wide variety of prey species, including invertebrates such as grasshoppers, locusts, crickets, beetles, spiders, snails and earthworms, and, despite its small size, small vertebrates such as geckos, snakes, frogs and mice. During the winter, the blue rock-thrush will also take fruits, berries and seeds. It forages by scanning the ground from an elevated vantage point where it sits alone, dropping to the ground when a suitable prey item is spotted. It also spends some of its time hopping and running on the ground in search of prey, and may occasionally catch small insects on the wing (2) (5).
Because of the wide ranging distribution of the blue rock-thrush, different populations and subspecies breed at different times. In general, the breeding period lasts for around two to three months, beginning in some parts of the range as early as January, although more often between April and May, and finishing in all areas by July (2). The blue rock-thrush builds a loosely constructed, shallow cup-like nest of coarse dry grass, moss and leaves, which is lined with soft grass, feathers and plant down. It is usually placed around two to five metres off the ground, under overhanging rocks or in crevices on cliffs. The female blue rock-thrush lays between 3 and 6 eggs in a clutch, which hatch after an incubation period of 12 to 15 days. The young chicks remain in the nest for around 15 to 18 days, and remain dependent on the adult for around two weeks after fledging (2).
