Brief_description |
A small pan with open water and fringing vegetation. Has an impressive variety of waterbirds, with good counts of herons, African Spoonbill, flamingos and Greyheaded Gull. Available counts are not enough to give a good picture of seasonal variations, but some herons, Greater Flamingo and Hadeda seem to be commoner in winter, while Whitefronted, Threebanded, Blacksmith and Wattled Plovers, Avocet and Water Dikkop are commoner in summer. Greater Flamingo numbers have decreased; Greyheaded Gull numbers are rising. Numbers of Little Bittern, Purple Gallinule, and Grass and Marsh Owls, are reasonable. Occasional raw sewage overflow and wandering domestic dogs are potential threats. |
