Habitat Comparison
Mauritius Duck
Historically restricted to the Mascarene Islands (Mauritius and Réunion) in the Indian Ocean. Now extinct. Presumably inhabited freshwater wetlands and coastal areas before human colonization.
African Pygmy-goose
Freshwater lakes, ponds, and rivers with floating water lilies and other aquatic vegetation across sub-Saharan Africa from Senegal to Tanzania. Nests in tree cavities near water. Highly dependent on water lily vegetation.
Song & Call Comparison
Mauritius Duck
Extinct (EX). No recordings exist. As a small island Anas duck, likely produced a quiet quacking call. Closest living relatives among insular Indian Ocean teals give soft, nasal notes.
African Pygmy-goose
Male produces a soft, wheezy whistle; female gives a quiet, duck-like quack. Pairs exchange rapid twittering notes during courtship on lily-covered African pools.
Geographic Range & Migration
Mauritius Duck
African Pygmy-goose
Breeds across temperate to sub-Arctic Eurasia; winters in Africa, South Asia, and Southeast Asia.

Tiny. Males have glossy dark green head with orange facial patch and ear spot; chestnut-orange flanks; white underparts; black and green back. Females duller with dark eye-stripe. Small yellow-green bill.
About These Birds
Mauritius Duck
An extinct duck known from subfossil bones found on Mauritius and Réunion. Closely related to the Grey Teal. Went extinct after European settlement of the Mascarene Islands in the 17th century due to hunting and introduced predators.
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.
