Bird counts were carried out at thirty-four study sites within a perimeter of 10 km from the shorelines of the two lakes, while all bird captures were conducted on a few sites along the shorelines of the two lakes. Both counting (22 missions) and capturing (15 missions) produced records of 297 bird species. A total of 2135 birds of 110 species were ringed, with total numbers of ringed birds per mission ranging from 34 (lowest in November 2010) to 294 (November 2008). The most commonly ringed bird species were Redbilled Teal (636), African Jacana (408), White-faced Duck (218), Blacksmith Lapwing (113), Kittlitz's Plover (84), Wood Sandpiper (53), African Snipe (35), Redbilled Quelea (32), Barn Swallow (31) and Hottentot Teal (29). Most of the waterbird species were captured during the cold/dry to hot/dry seasons (July to November) when water levels on both lakes were low. Ten species of duck, goose and teal captured accounted for 43.3% of all the birds ringed.
