Habitat Comparison
Amsterdam Duck
Historically restricted to Amsterdam Island in the southern Indian Ocean. Now extinct. Presumably inhabited the island's freshwater sources and coastal areas.
Mandarinente
Wooded lakes, rivers, and ponds surrounded by dense forest. Unlike most ducks, regularly perches in trees and nests in tree cavities.
Song & Call Comparison
Amsterdam Duck
Extinct (EX). No recordings exist. As an Anas relative, likely gave a typical duck-like quacking call; male may have had a soft whistled note similar to other island teals.
Mandarinente
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.
Geographic Range & Migration
Amsterdam Duck
Breeds on sub-Antarctic islands of the South Indian Ocean; disperses across the Southern Ocean when not nesting.
Mandarinente
Native to East Asia including eastern Russia, China, Japan, and Korea. Feral populations established in Britain and western Europe.

Extinct Amsterdam Island duck known only from bones and a single historical description. Presumably brown plumage typical of Anas dabbling ducks. Flightless or near-flightless; extirpated by introduced predators.
Mandarinente
Breeding males have an elaborate pattern of orange, green, white, and purple with distinctive orange sail feathers on the back. Females are grey-brown with a white eye-ring and stripe.
Small red bill in breeding males, pinkish in females
About These Birds
Amsterdam Duck
An extinct diving duck known from subfossil remains discovered on Amsterdam Island in the southern Indian Ocean. Flightless or nearly flightless; probably resembled the Laysan Duck in size. Went extinct around 1800 following human colonization of the island.
Mandarinente
Die Mandarinente gilt weithin als die schönste Ente der Welt. In der ostasiatischen Kultur symbolisiert sie Liebe und Treue, da sie feste Paarbindungen eingeht. Anders als die meisten Enten nistet die Mandarinente in Baumhöhlen bis zu 9 Meter über dem Boden, sodass die erst einen Tag alten Küken zu Boden springen müssen.
