About These Birds
African Pygmy-goose
A tiny jewel-like duck—one of Africa's smallest waterfowl. Males have iridescent green-and-white plumage, an orange bill, and a dark green cap; females are mottled brown. Found on lily-covered lakes in sub-Saharan Africa. Perches on water lily pads and feeds on their seeds and flowers.
Freckled Duck
雀斑鸭是澳大利亚西南部特有的稀有潜鸭，体羽以褐色为主，密布浅色圆斑，如同雀斑，故名。外形独特，在分类上位于树鸭和真正潜鸭之间。栖息于永久性深水湖泊和沼泽，主要在夜间活动，以水生植物为食。由于湿地排干和猎捕，被列为易危物种。
