Lilac-breasted Roller
Coracias caudatus
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. Voice: The call of a lilac-breasted roller is a harsh, sawing "rak rak rak" that is given during flight. Usually, the bird will perch to sing.
