distribution and habitat

The red-browed silk cuckoo occurs in the north and east of Madagascar. It prefers dense vegetation such as tropical rainforests , secondary forests and other densely vegetated habitats up to an altitude of 2,500 m. The IUCN does not consider the species to be endangered due to its abundance and wide range.

Way of life

The red-forehead silkworm usually moves in pairs on the ground in forests with dense undergrowth. There he looks for food, which mainly consists of beetles , crickets , ghosts , spiders and butterflies , including caterpillars . Small lizards or fruits and seeds are less common . In the event of danger, he usually runs instead of flying.

Etymology and history of research

Jacques Pucheran described the red-browed silk cuckoo under the current name Coua Reynaudii . He named Madagascar as the place where it was found. »Coua« is a Malagasy onomatopoeia for the call of the pointed-headed silk cuckoo ( Coua cristata ), which sounds like »Koa«. Louis Pierre Vieillot called this Le Coulicou Coua (Coccyzus cristatus) in 1817 , but was not sure whether Coua was derived from his reputation or some other characteristic. It was Heinrich Rudolf Schinz who introduced the genus of the silk cuckoo in 1821 for the giant silk cuckoo ( Coua gigas ), which was later added to the red-forehead silk cuckoo. The specific epithet is dedicated to Jean Reynaud (1806–1863).
