About These Birds
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.
Keel-billed Toucan
The keel-billed toucan is the national bird of Belize and one of the most recognizable birds in the Neotropics. Its oversized bill, which can be a third of its body length, is actually very light due to its hollow honeycomb structure. Toucans roost communally, with up to six adults squeezing into a single tree cavity.
