Hi Everyone
There seems to be no resolution on this id yet!
I'd make a couple of comments. The Rough-legged Buzzard Buteo lagopus has not been recorded in South Africa, it is only a vagrant to North Africa (eg Lybia) so it
is very unlikely in SA.
I've seen many Steppe Buzzards in Africa and this bird doesn't look like any I've seen.
In his last posting, TwoBoy states that it was 30 cm (?long). This would knock out all suggestions to date except for the Dickinson's Kestrel suggested by TwoBoy. To me,
neither this id nor the suggested length seem possible.
Another possibility is the Long-legged Buzzard Buteo rufinus. I've never seen this bird,
it's reported as a summer vagrant to NW southern Africa. Does its head ever get as pale as the bird photographed? It's also large at 50-66 cm.
My money is still on a pale Wahlberg's, which, as Paul pointed out, is common in Kruger
and has very variable plumage from very dark to very pale phases.
