Sobre
O pato de Baer é um pato mergulhador criticamente ameaçado nativo do nordeste da China e adjacente Rússia. Os machos têm cabeça e pescoço verdes com olhos brancos característicos. Cria em zonas húmidas de floresta inundada e hiberna no Sul e Sudeste da Ásia. As populações colapsaram nos últimos anos de números anteriores de milhares para apenas centenas, tornando-o um dos patos mais em perigo do mundo. As causas incluem caça, perda de habitat e perturbação.
