The lilac-breasted roller (Coracias caudatus) is an African bird of the roller family, Coraciidae. It is widely distributed in Southern and Eastern Africa, and is a vagrant to the southern Arabian Peninsula. It prefers open woodland and savanna, and it is for the most part absent from treeless places. Usually found alone or in pairs, it perches at the tops of trees, poles or other high vantage points from where it can spot insects, amphibians and small birds moving about on the ground. Nesting takes place in a natural hole in a tree where a clutch of 2–4 eggs are laid, and incubated by both parents, who are extremely aggressive in defence of their nest, taking on raptors and other birds. During the breeding season the male will rise to a fair height (69 to 144 metres), descending in swoops and dives, while uttering harsh, discordant cries. The sexes do not differ in coloration, and juveniles lack the long tail streamers of adults. This species is unofficially considered the national bird of Kenya. Alternative names for the lilac-breasted roller include the fork-tailed roller, lilac-throated roller (also used for a subspecies of purple roller) and Mosilikatze's roller.In the field, these robust, large-headed birds are often perched alone on a tree in a grassy clearing, and are almost unmistakable with their colourful plumage tones. The lilac throat of the nominate subspecies C. c. caudatus deepens into a darker lilac breast. The crown to mantle is olive, and the cheeks and ear coverts a lilac-rufous. In subspecies C. c. lorti however, the crown to mantle is greenish blue instead of olive, and the breast azure. The throat is lilac, and some lilac-throated rollers have a lilac patch or rufous-brown tinges on the lower abdomen. Both subspecies have long, black outermost tail streamers that are absent in juveniles.
