Lagden's bushshrike

Lagden's bushshrike (Malaconotus lagdeni) is a bird species in the bushshrike family (Malaconotidae) native to Africa. It is a stocky bird with yellow or orange-yellow underparts, olive green upperparts, a grey head and heavy bill. Two subspecies are recognised, one found in west Africa and one in central Africa.

Taxonomy

Richard Bowdler Sharpe described the species in 1884 as Laniarius lagdeni, from a specimen collected in the vicinity of Kumasi in Ghana. However there were no further sightings of the species in this locale for the whole 20th century. He named it in honour of Sir Godfrey Yeatman Lagden, an English diplomat who served as Chief Clerk to the Secretary of the State of Transvaal and Secretary to Sir Owen Lanyon.Template:Sfn

There are two disjunct populations, classified as separate subspecies: Malaconotus lagdeni lagdeni, from eastern Sierra Leone, through Liberia, Ivory Coast and southern Ghana to western Togo, and Malaconotus lagdeni centralis, in the Albertine Rift montane forests in Uganda.Template:Sfn Template:Sfn The western subspecies has more orange tinge on the underparts while the central African subspecies has none.Template:SfnTemplate:Sfn

Description

Lagden's bushshrike is a stocky bird some 23 cm long with a heavy black bill. The adult male and female are similar in plumage. The upper parts, including the wings and tail, are olive-green, and the head is dark grey. The underparts are yellow, sometimes tinged orange on the breast. The tail is edged with yellow. The legs are bluish grey.Template:Sfn

Juveniles have duller plumage overall, with brownish upperparts yellow or white underparts, sometimes with some streaking, and a grey-brown bill.Template:Sfn

It can be distinguished from the fiery-breasted bushshrike as the latter species has a much redder breast and light grey head.Template:Sfn

The call has been described as a hoop hoop or a toot toot....Template:SfnTemplate:Sfn Others have said it is a "bell note" call, like the grey-headed bushshrike but at a higher pitch.Template:Sfn This avian vocalization has been described using the odd consonant-filled word "Chrrrr".Template:Efn-ua Recordings of the calls exist.

Distribution and habitat

Its natural habitats are subtropical or tropical moist lowland forests in west Africa to an elevation of around 700 m, and subtropical or tropical moist montane forests in Rwanda, Uganda and the Democratic Republic of Congo at an elevation of 2100 to 2800 m.Template:Sfn Classified in the IUCN Red List as Near Threatened, it is becoming rare due to habitat loss. One of the 1,487 bird species of eastern Africa,Template:Sfn it is considered to be a "very rare mountain forest species".Template:Sfn It is one of the 235 different species sighted at Kyabobo National Park.

Feeding

Lagden's bushshrike hunts large insects, such as grasshoppers, and other arthropods, as well as small vertebrates, foraging in forest canopy 10–30 m (35–100 ft) above the ground.Template:SfnTemplate:Sfn
