About These Birds
Madagascar Pochard
O pato-do-madagáscar é um pato mergulhador criticamente ameaçado endémico da ilha de Madagáscar. Considerado possivelmente extinto durante décadas, foi redescoberto em 2006 no lago Manambolomaty. As populações são extremamente pequenas, tornando-o um dos patos mais raros do mundo. Enfrenta graves ameaças de degradação de habitat, introdução de peixes exóticos, e caça. Intensos esforços de conservação estão em curso para evitar a sua extinção.
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.
