Distribution

Sub-Saharan Africa. Generally resident; some populations move seasonally.

Taxonomy

Variation in the colouration and streaking of the upperparts defines the different subspecies, but most are poorly differentiated. Authors recognise up to 9 races [2].

Clements recognises the following subspecies [1]:

The IOC further recognises subspecies [3]:

  • C. n. huambo: western and central Angola

Habitat

Open grassland and savanna; prefers rank vegetation.

Behaviour

Usually solitary. Inconspicuous and shy, except when calling (often from a prominent perch) in the breeding season.

Diet

Forages low in vegetation or on the ground, mainly for invertebrates, but also for seeds.

Vocalisation

The call is distinctive; a loud croak "q-RRRRP" which is about 1 second long, repeated every 2 seconds.
