About These Birds
Greater Flamingo
The greater flamingo is the most widespread flamingo species and one of the most recognizable birds in the world. Their pink color comes entirely from carotenoid pigments in their crustacean and algal diet. Flamingos are social birds that breed in enormous colonies sometimes numbering tens of thousands.
Japanese White-eye
The Japanese white-eye is a familiar garden bird across East Asia, beloved in Japan where it is called mejiro. These sociable birds form flocks outside the breeding season and are important pollinators of plum and cherry blossoms. Unfortunately, introduced populations in Hawaii have become invasive, competing with native honeycreepers.
