Abessinische Racke

Bestimmung

The Abyssinian roller is a large bird, nearly the size of a jackdaw at 28–30 cm (11–12 in). It has a warm brown back, with the rest of the plumage mainly blue. Adults have 12 cm (4.7 in) long tail streamers. Sexes are similar, but the juvenile is a drabber version of the adult. Abyssinian roller is striking in its strong direct flight, with the brilliant blues of the wings contrasting with the brown back and the long tail streamers trailing behind. The call of the Abyssinian roller is a harsh crow-like gak sound, or a screeched aaaargh.

Verhalten

Abyssinian rollers often perch prominently on trees, posts or overhead wires, like giant shrikes, whilst watching for the large insects and small rodents on which they feed. They will dash into the smoke of a forest fire for disturbed invertebrates. They are fearless, and will dive and roll at humans and other intruders. The display of this bird is a lapwing-like display, with the twists and turns that give this group its English name. It nests in a scantily lined hole in a tree or building, and lays three to six eggs.
