Anseranas semipalmata. In the wet season, Magpie Geese form large colonies whose honking sounds carry across the water. Floating nests are constructed and the birds mate-one male and one or two females. By the middle of the wet season, the males are incubating 4-15 (but typically 8) eggs.he Bulkuru sedge or Water Chestnut (Eleocharis dulcis) becomes important, the Magpie Geese digging their faces into the mud and using their hooked beaks to extract the starch-rich corms (underground parts of the stem); the heavy face-plate protects the birds in this activity.
