About These Birds
White-shouldered Ibis
75–80 cm. Large; dark brown with white shoulder patch; bare red facial skin. Critically Endangered; fewer than 250 birds known. Restricted to lowland Mekong forests of Cambodia, Vietnam, and Myanmar. Threatened by forest clearance and hunting; one of Asia's rarest birds.
Rosalöffler
Der Rosalöffler ist die einzige Löfflerart Amerikas und einer der auffälligsten Watvögel der westlichen Hemisphäre. Wie bei Flamingos stammt seine rosa Farbe von Carotinoid-Pigmenten aus seiner Beute an Krebstieren. Im 19. Jahrhundert wegen seiner Federn fast bis zur Ausrottung bejagt, haben sich die Bestände seither erheblich erholt.
