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.
Black Scoter
O pato-negro-americano é um grande pato marinho da América do Norte. Os machos são completamente pretos com bico com tubérculo proeminente e mancha amarela-laranjada. Cria em lagos e pântanos do Alaska e norte do Canadá. Hiberna em costas marinhas ao longo das costas do Atlântico e Pacífico. Muitas vezes agrupa-se com o menor pato-negro-europeu em costas europeias durante a migração. Até recentemente era considerado uma subespécie do pato-negro.
