This is Madagascar's own plover: the Madagascar plover, a close relative of the Kittlitz's plover (Charadrius pecuarius). It is identified, among other things, by its dorsal feathers, which give an almost mottled impression (which can be seen if you look closely at the picture). Unfortunately, this plover was in a difficult backlight on the embankment of a salt pool. To get the bird in the right light, two of us took a long detour and approached with the sun behind us - and to our great joy the individual remained on the embankment.
