Fleckenkuckuck

Bestimmung

The Asian emerald cuckoo grows to a length of about 18 cm (7 in). The adult male has an iridescent dark green head, upper parts and upper breast, a white lower breast and a green barred belly. Bare skin round the eye is orange and the beak is orange/yellow tipped with black. The adult female has coppery-green upper parts, rusty brown crown and nape and green-barred underparts. Both sexes show a white band on the underwing when in flight. The underparts of the juvenile male lack the white lower breast and are more heavily barred. The voice is a “chweek” uttered while flying, and various whistled twitters.

Taxonomie

The Asian emerald cuckoo was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other cuckoos in the genus Cuculus and coined the binomial name Cuculus maculatus. Gmelin based his description on the "Spotted Curucui" from Ceylon that had been described and illustrated in 1776 by the English naturalist Peter Brown. The Asian emerald cuckoo is now placed together with 12 other species in the genus Chrysococcyx that was introduced in 1826 by the German zoologist Friedrich Boie. The genus name combines the Ancient Greek χρυσος khrusos meaning "gold" with κοκκυξ kokkux "cuckoo". The specific epithet maculatus is from Latin and means "spotted" or "blotched". The species is monotypic: no subspecies are recognised.

Verhalten

The Asian emerald cuckoo mainly forages in the upper levels of the canopy where it feeds on insects and other small invertebrates, including ants, caterpillars and bugs. It is a brood parasite, the females laying their eggs in the nests of other birds, such as the crimson sunbird (Aethopyga siparaja) and the little spiderhunter (Arachnothera longirostra).
