Habitat Comparison
Mandarin Duck
Wooded lakes, rivers, and ponds surrounded by dense forest. Unlike most ducks, regularly perches in trees and nests in tree cavities.
Freckled Duck
Dense inland freshwater swamps, tea-tree bogs, and reedy lakes across southern and inland Australia. Highly nomadic; follows ephemeral inland flooding. Key breeding sites in Murray-Darling Basin swamps.
Song & Call Comparison
Mandarin Duck
Male gives a low whistled 'hib' or 'weep'. Female utters a soft quacking 'kek'. Generally quiet and secretive. No loud territorial song; vocalizations subtle and brief.
Freckled Duck
Soft, nasal 'quacking' and grunting sounds. Considered a quieter, more secretive duck than most. Males give a soft wheeze; females give low quacks. Not vocal by duck standards.

About These Birds
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
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。
