The national bird of both Kenya and Botswana, the lilac-breasted roller is often considered one of the most beautiful birds in the world with its pastel plumage, striking field marks and long tail streamers. More than one visitor in Africa searching for mammals leaves the continent a birder, naming this attractive species as their spark bird.

Common Name: Lilac-Breasted Roller, Lilac-Throated Roller
Scientific Name: Coracias caudatus
Scientific Family: Coraciidae

Appearance:

  • Bill: Large, thick, black, straight with a slight hook at the tip
  • Size: 14-15 inches long with 20-23-inch wingspan, large head, short neck, forked tail with long, thin streamers on the outer feathers when mature
  • Colors: Buff, white, purple, blue, turquoise, green, black, tan
  • Markings: Genders are similar with a white or creamy buff face with a dark eye line and prominent bristles at the base of the bill. The chin is creamy white, cheeks are dark tan with a purple wash and the throat and upper breast are purple, most often a lilac shade but with some hue variation and darker shades lower on the body. The throat and upper breast also show thin white vertical streaks. The upper wings and back are tan, but the scapulars and primary feathers are rich, royal blue. The underparts are bright turquoise. The tail is blue with black outer streamers. In flight, the wings show a light blue patagium and wingpit contrasting strongly with a dark blue primary and secondary feathers. Legs and feet are greenish yellow.
    Juveniles are dull overall with shades of brown and tan but develop adult colors quickly, though they lack the outer tail streamers.

    Foods: Insects, lizards, snails, amphibians, rodents, small birds (See: Carnivorous)

    Habitat and Migration:

    These birds prefer open woodland or grassland habitat with widely scattered trees, shrubs or poles to serve as hunting perches. They are relatively common and widespread throughout much of southern Africa, south of the Congo River basin but extending as far north as Ethiopia in the eastern part of the continent. They are absent from coastal areas of southwestern Africa.

    Lilac-breasted rollers do not typically migrate but may be somewhat nomadic in search of the best food sources in different seasons or times of drought. Vagrant sightings are regularly recorded in the southern part of the Arabian peninsula, specifically Oman and Yemen.

    Vocalizations:

    These rollers have a harsh, raspy call that lasts less than a second but may be quickly repeated. The pitch does not vary, and the tone has a rattling quality. While mostly silent, they are more vocal during the breeding season or when they feel their territory is threatened.

    Behavior:

    These birds are typically solitary or are found in pairs, but may stay in small family groups during the winter months. They perch on high vantage points at the very tops of trees and poles, and stay still while watching for prey to approach. After dropping onto a victim, they may beat their prey against a rock or on the ground to kill it before swallowing it whole. All rollers, including the lilac-breasted, are known for their acrobatic, agile flight, aided by the tail streamers they are able to use as rudders while flying.

    Reproduction:

    These are monogamous birds believed to mate for life. The male's courtship displays include stunning flight dives with a rolling or rocking quality as well as loops and twists. These are cavity-nesting birds that usurp old kingfisher or woodpecker holes from 6-30 feet above the ground, and will occasionally nest in empty termite mounds. Both genders aggressively defend their nesting territory, even chasing off much larger raptors and other predators.

    The eggs are plain white with 2-4 eggs per brood, and only one brood laid per year. Both parents share incubation duties for 22-24 days, and after hatching, they continue to care for the altricial young for another 18-20 days. Once the chicks have fledged, they continue to rely on parental care for up to another month.

    Attracting Lilac-Breasted Rollers:

    These birds do not typically stay in areas near human habitation, but leaving isolated trees or poles available for tall perches can tempt them to visit, especially in less populated areas. Where other nesting sites are scarce, they may use nesting boxes. In the field, they are unafraid when humans approach and it can be easy to get spectacular views.

    Conservation:

    These birds are not considered threatened or endangered, though habitat preservation can help keep their population numbers stable. Poaching for the pet trade is a minor threat that can have severe consequences for local breeding populations.

    Lilac-breasted rollers have uniquely adapted to one natural disaster. While brush fires can be devastating to many animals and birds, these rollers will deliberately hunt near the edges of fires where prey is fleeing and less wary of predators.
