The amethyst cuckoo ( Chrysococcyx xanthorhynchus ) is a Southeast Asian species of cuckoo. The species includes two subspecies: C. x. xanthorhynchus and C. x. amethystinus ( Vigors 1831).

features

The male of the nominate form is colored violet-shiny on the upper side, the undersides are white with black sparrowth . The sexual dimorphism is very pronounced: the head plumage of the female is brown-gray, the top of the plumage is brown-green, shiny. The underside is white with shiny green-brown sparrows. Both sexes have a striking red ring around the eyes. The males of the subspecies C. x. amethystinus appear shiny blue with violet reflections. The female looks like the nominate form. The amethyst cuckoo is about 16 cm tall.

distribution

The amethyst cuckoo is a resident of the Orientalis . The distribution area of the nominate form includes the rear Indian peninsula , Sumatra , Java and Borneo , while C. x. amethystinus occurs on most of the islands in the Philippines . The amethyst cuckoo is rare in most of the distribution area; larger populations occur locally, e.g. B. on the Malay Peninsula . For this reason, as well as the size of the distribution area and the undemanding nature of the choice of habitat , the amethyst cuckoo is not considered endangered by the IUCN , although no population size estimates are available.

Way of life

The amethyst cuckoo inhabits evergreen forests of the lowlands, mangroves and wetlands as well as anthropogenic habitats such as plantations , gardens and parks . The main food is insects , which are often caught in flight. Fruits are also part of the diet. Like all other species of the genus Chrysococcyx , amethyst cuckoos are breeding parasites . The main host birds are species of nectar birds , warblers and timalia .
