The introduction picture is how we usually see these in the field. They are endemic to the South Western Africa region, which basically means South Africa, Namibia and Botswana.
In flight the white under-wing contrast strongly with the dark primaries on the wing tips, as well as white “windows” on top of wings.
The beautiful barred rump can only really be seen up close, and here the raptor rehab center came to the rescue. We found they had some birds with wing damage (mostly) and took a few pictures.
They also have long reddish legs and wonderful calls. Always nice sight in the wild.
