The adult male has a bluish slate crown, often with a central rufous patch; black nuchal collar often incomplete; back and scapulars rufous, spotted or barred with black; tail mainly rufous, narrowly white-tipped and with a black subterminal band; outer tail feathers sometimes white, barred black on the inner web; wing coverts and secondaries light bluish slate, more or less spotted or barred with black; primaries black, spotted or deeply notched white on inner webs; throat and side of head white, the latter with two vertical stripes; undersides buffy, often with black spotting on the midsection and flanks.

Behavior Disc 1 · 2011
Perch-hunts from high or low vantage points, transsects areas by flying low and dives down for prey such as mammal or reptiles; frequently hoovers to scan the ground below. Attends grass fires. These birds like the European Kestrel might be able to assess prey density by determining UV reflection of urine tracts of small mammals.
