Pterocles exustus

Temminck

Senegal#R

.

May be closely related to P. namaqua. Recent study#R suggests that these two together with P. orientalis may belong in a clade that includes also the two Syrrhaptes species; or, alternatively, that all five of these may form a group with P. gutturalis, P. personatus, P. coronatus, and possibly including also P. alchata and P. burchelli; further study needed. Proposed race somalicus (Somalia) synonymized with ellioti, and emini (near L Victoria) with olivascens. Six subspecies recognized.

Subspecies and Distribution

  • P. e. ellioti Bogdanov, 1881 – SE Sudan E to Eritrea, N Ethiopia and Somalia.
  • P. e. olivascens (E. J. O. Hartert, 1909) – SE South Sudan, S Ethiopia, Kenya and N Tanzania.

  • P. e. hindustan R. Meinertzhagen, 1923 – SE Iran, Pakistan and most of India.
