Шаблон:Short description Шаблон:Speciesbox

The dusky long-tailed cuckoo (Cercococcyx mechowi) is a species of cuckoo in the family Cuculidae. It is found in forests in Central Africa. The IUCN has assessed it as a least-concern species.

Taxonomy

The species was described by Jean Cabanis in 1882.[1] It is monotypic.[2] The specific epithet mechowi honours Friedrich Wilhelm Alexander von Mechow, a Prussian explorer.[3] The name occidentalis for a population with different songs is a nomen nudum.[4]

Description

The dusky long-tailed cuckoo is about Шаблон:Convert long and weighs Шаблон:Convert. The head, nape and upperparts are dark brown, washed sooty-grey and with a purple-blue iridescence. The wings are dark brown, with buff and white spots. The underparts are white, with blackish-brown bars, and the vent is buff. The tail is long and graduated. The eyes are dark brown, the beak is greenish-black and the feet are yellow. The male and female are alike. The juvenile bird has a blackish throat and rufous bars on its upperparts. The nestling's skin is black, and it has a yellow rump and pale feet.[2]

Distribution and habitat

This cuckoo has a discontinuous distribution[2] and is found in Angola, most of Cameroon, the Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon, Tanzania, and Uganda.[5] Populations west of the Bakossi Mountains, in northwestern Cameroon, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, Sierra Leone, and Togo, are now considered a distinct species, the whistling long-tailed cuckoo (C. lemaireae) due to their differing calls.[6] Its habitat is forests, preferring ones with dense undergrowth and lianas. It also occurs in tall secondary forests and forests along rivers.[2]

Behaviour

The dusky long-tailed cuckoo is often found in the undergrowth or mid-canopy. It eats caterpillars, ants, beetles, spiders, snails and seeds and joins mixed-species foraging flocks. Pairs often call from treetops.[2] Its calls include hu hee wheeu and a series of notes that accelerates and then slows and descends.[7] This cuckoo is a brood parasite. The blue-headed crested flycatcher, brown illadopsis and possibly the forest robin have been observed as hosts. Its breeding may be associated with the wet season.[2]

Status

The species does not appear to have substantial threats, and its population appears stable. The IUCN has assessed it as a least-concern species.[5]
