About These Birds
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
Japanese White-eye
O olho-branco-japonês é uma pequena ave verde-oliva com anel ocular branco característico, muito popular como canário de gaiola no Japão e amplamente distribuído na Ásia.
