The warbling white-eye (Zosterops japonicus), also called the Japanese white-eye, is a small olive-green passerine of the family Zosteropidae, distinguished by its conspicuous white orbital ring. Native to East Asia — Japan, Korea, the Philippines, Indonesia, and the Russian Far East — it is omnivorous, feeding on nectar, fruit, and insects at all foliage levels. It serves as the primary documented pollinator of Camellia japonica in Japan, visiting the flowers in winter when insect pollinators are scarce and transferring pollen between trees. Introduced populations established on the Hawaiian Islands since 1929 are now the most abundant land birds there, where the species is considered invasive.
