Black-rumped Buttonquail - BirdForum Opus

Turnix nanus

Identification

Length 14-16 cm, female > male.
It has a ginger face and throat. The pale belly is unmarked and the dark back and rump contrast with paler wings in flight. The legs are a pale flesh colour while eyes are pale blue to white. Face and throat is more gingery and less marked in female, with male overall less bright.

Similar species

Black-rumped Buttonquail is larger and more richly coloured than Small Buttonquail. Hottentot Buttonquail has less constrasting rump and uppertail, has spots or barring from middle breast to belly, yellow legs and pale yellow eyes.

Distribution

Africa south of the Sahara: from Kenya west to Uganda and Nigeria (but has been occasionally found further west) and from there south to Angola and eastern South Africa.

Taxonomy

This is a monotypic species[1].

Black-rumped Buttonquail and Hottentot Buttonquail were until recently considered one species.

Habitat

Most common in areas with low grass though can occur in shrub or edges of taller vegetation. Found from sea level to 1800 m asl.

Behaviour

Partly migratory with movements poorly understood, but in most areas more likely encountered during wet season. Most often encountered singly on in a pair.

Feeds on the ground, likely on grass and other seeds as well as invertebrates. It is more likely to stay on the ground and try to run away from danger than to flush.

Vocalisation

Calls during breeding season described as "boom-boom" or "oooop-oooop" given as series that are fast and low pitch. Calls seems to be given during breeding attempts only and may only be given for a few weeks.
