Identification

Rollier à longs brins
adult

The sexes are similar.
The adult Lilac-breasted Roller can be recognized by its long streamers formed by the outer rectrices which extend its tail and gave it its French name. Its English name, Lilac-breasted Roller, alludes to its lilac-coloured throat and chest.
In flight, the bird is large and blue. Its wings, like all roller species, are a range of blues from cyan to indigo to royal blue. Additionally, its whole back (back, belly, and tail) is blue.
When perched, it is much less visible in flight, with the brighh colours concealed. From behind, its brownish-fawn mantle and scapulars, and from the front, its violet chest are much less noticeable.
The head is tricoloured. The face and chin are whitish, the crown and neck pale blue-green, and the cheeks chestnut. The beak is strong, slightly hooked, and black. The short legs are dull yellow.
Immature birds resemble adults, with duller colours, and do not have tail streamers.

Voice song and cries

Rollier à longs brins
adult

As with all rollers, the vocalizations of this species, which do not deserve the designation of a song, are unpleasant to the human ear. It's raspy and discordant cries punctuated by repeated dry scratches are heard especially during territorial defense and during mating.

Habitat

Behaviour character trait

Rollier à longs brins

The Lilac-breasted Roller is territorial. It lives alone or in pairs, but is usually only seen on its own.

Rollier à longs brins
immature
It noisily expresses its disapproval of intrusions and won't hesitate to oust other species from its territory.
It hunts from a perch, usually on top of a tree, shrub, post, or any other elevated support from which it can survey its surroundings. It has been known to perch on the back of a herbivore in the absence of suitable perches.
It dives for insects at ground level and often returns to the same perch to eat its prey.
It is drawn to fires, both natural and lit, with the edge of the fire providing fleeing and dead prey that it covets.
The Lilac-breasted Roller mostly travels by flight, even for short distances, as its short legs don't really allow it to walk and instead it only does so clumsily.
Its courtship displays include short flights, the birds leaving their perch only to return quickly before flying off again. They will rise about ten metres facing each other, then fall with their wings closed, do a loop with rapid beating of the wings to rise again turning. Just before mating, when they reach the peak of excitement, the mates will engage in a simulated battle.

Flight

Dietfeeding habits

The Lilac-breasted Roller mainly feeds on large arthropods, mostly insects such as grasshoppers, beetles, ant lions, but also on small vertebrates such as lizards, small amphibians and occasionally small birds.

Reproduction nesting

The female lays 2 to 4 eggs in a nest placed 4 or 5 meters in the air, in a preexistent lodge or in a natural hole. The eggs are incubated by both parents and incubation lasts about 20 days (19 to 24 days, according to sources).

Geographic range
