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.
