[edit] Taxonomy

Robin-chats were formerly classified as members of the Thrush family (Turdidae), but as first proposed by Sibley and Monroe (1991)[4] are now usually recognized as members of the Old World Flycatchers (Muscicapidae). Some authors place this species in the genus Dessonornis following application of controversial criteria proposed by Tobias et al. (2010)[3][6]. This is a polytypic species.

[edit] Subspecies

There are 4-7 subspecies depending on the authority[1]:

  • C. c. iolaema:
  • C. c. kivuensis:
  • Eastern DRC (Kivu highlands) and south-western [[Uganda]
  • Like iolaema but more richly colored below.
  • C. c. namaquensis:
  • Southern Namibia to Orange Free State and western Transvaal
  • Like nominate but larger with stronger supercilium
  • C. c. caffra:

The subspecies drakensbergi and vespera along with ardens are generally considered invalid[2].

[edit] Habitat

Forest edges, bushveld, scrub and fynbos, gardens and parks.

[edit] Behaviour

[edit] Diet

The diet includes a wide variety of insects, spiders, caterpillars invertebrates, small frogs, lizards and some fruit and other vegetable matter.

[edit] Vocalisation

Song by both sexes (female usually shorter and muted) a series of repetitive melodious high pitched phrases starting with soft down-slurred whistles. Also may mimic other species.
