About These Birds
Whooper Swan
O cisne-cantor é um grande cisne nórdico que cria em zonas húmidas da Escandinávia, Rússia e partes da Islândia. É distinguido do cisne-mudo pela maior quantidade de amarelo no bico, pescoço mais reto e voz sonora. Hiberna em costas e grandes corpos de água na Europa Ocidental, Japão e partes do sul da Ásia. Tem um voo forte e gralha em voz alta durante a migração. É o símbolo nacional da Finlândia.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
