About These Birds
Ferruginous Duck
O pato-castanho-ferrugíneo é um pequeno pato mergulhador encontrado em zonas húmidas de água doce do Paleártico. Os machos têm uma coloração castanho-ferrugíneo brilhante rica com olho branco marcante. Habita lagos, pântanos e rios lentos com vegetação densa de juncos. Está classificado como quase ameaçado, com populações em declínio em grande parte do seu alcance devido à drenagem de zonas húmidas e perturbação. É uma espécie-alvo de programas de conservação europeus.
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.
