Mandarin Duck
Wooded lakes, rivers, and ponds surrounded by dense forest. Unlike most ducks, regularly perches in trees and nests in tree cavities.
Spectacled Duck
Clear fast-flowing rivers and streams in temperate forest from central Chile and adjacent Argentina south to Tierra del Fuego. Requires cold turbulent mountain rivers with riparian forest. Avoids slow or muddy water.

Spectacled Duck
Emits deep, guttural quacking notes; alarm is a loud, repeated honking bark. Calls are resonant and powerful, carrying far along fast-flowing Patagonian rivers.

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.
Spectacled Duck
O pato-dos-espelhos é um pato pequeno endémico do sul do Chile e da Argentina. Os machos têm plumagem castanho-escuro com espelhos alares brancos e verdes característicos. Habita rios, lagos e zonas húmidas costeiras nas florestas temperadas patagónicas. É uma espécie pouco conhecida e pouco estudada. É classificado como quase ameaçado devido ao declínio da qualidade e disponibilidade do habitat. É um residente permanente e não migratório do extremo sul da América do Sul.
