Taxonomy

The Marsh Tchagra is sometimes placed in the monotypic genus Antichromus or included in genus Tchagra with the other Tchagras.

Bocagia minutus has three subspecies:

B. m. minuta

Sierra Leone east to South Sudan, eastern Sudan, and Ethiopia, south to western Kenya and northwestern Tanzania
Has a black 'V' marking on the mantle and scapulars

B. m. reichenowi

Eastern and southern Tanzania, southern Malawi, eastern Zimbabwe and Mozambique

B. m. anchietae

Southern DRC to Angola, northern Zambia, south-western Tanzania and northern Malawi

B. m. reichenowi and B. m. anchietae are sometimes split as Anchieta's Tchagra; named after Portuguese explorer José Alberto de Oliveira Anchieta by his zoologist compatriot José Vicente Barbosa du Bocage in 1869.

Habitat

Rank grassland, bracken and sedges and shrubs associated with wetlands.

Behaviour

Diet includes large insects; forages near the ground in dense cover; sometimes hawks insects.

Breeding

Probably monogamous; territorial. The nest is a bulky, but neat cup of plant material and spider web, usually in a bush within a metre of the ground. One to three eggs are laid.

 ==Taxonomy==
-The Marsh Tchagra is sometimes placed in the monotypic genus Antichromus, and then named as Blackcap Bushshrike. The dark Angolan subspecies of Marsh Tchagra was formerly sometimes split as Anchieta's Tchagra, Tchagra anchietae, named after Portuguese explorer José Alberto de Oliveira Anchieta by his zoologist compatriot José Vicente Barbosa du Bocage in 1869.
+The Marsh Tchagra is sometimes placed in the monotypic genus ''Antichromus'' or included in genus [[:Category:Tchagra|Tchagra]] with the other Tchagras.

 ==Habitat==
-These are species typically of scrub, open woodland, semi-desert and cultivation in sub-Saharan Africa.
+Rank grassland, bracken and sedges and shrubs associated with wetlands.
 ==Behaviour==
-These are solitary birds which tend to skulk low down or on the ground. They have distinctive whistled calls and can be readily tempted into sight by imitating the call, presumably because the tchagra is concerned that there is an intruder in its territory.
+Diet includes large insects; forages near the ground in dense cover; sometimes hawks insects.
+====Breeding====
-They hunt large insects from a low perch in a bush.
+Probably monogamous; territorial. The nest is a bulky, but neat cup of plant material and spider web, usually in a bush within a metre of the ground. One to three eggs are laid.
