About These Birds
Tundra Swan
O cisne-de-bewick é um cisne branco médio com distribuição circumolar ártica. Criando na tundra ártica, hiberna em Europa Ocidental, sul da Ásia e leste da Ásia. Pode ser distinguido do cisne-cantor pelos padrões variáveis de amarelo e preto no bico, que são únicos para cada indivíduo como impressões digitais. As populações migrantes da Europa Ocidental criaram ao longo das costas da Grã-Bretanha e Países Baixos. É classificado como espécie distinta por algumas autoridades.
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.
