I expect you have already had this comment but these are not Crowned Plovers (Vanellus coronatus) To confuse life that have several different names but only one latin name. These include: white-crowned lapwing, white-headed lapwing, white-headed plover or white-crowned plover (Vanellus albiceps). Very nice photo though. I am going to Kaingo for the first time this year and would love to see some.
