NAME: The Latin genus name is for birds with a white circle around the eye – ‘Zosterops’ means ‘belt’ and ‘eye’. The Latin species name ‘japonicus’ as well as part of its English name refer to its native range. Its Japanese name is ‘Mejiro’.
HABITAT: Forest, but also urban gardens where it was introduced.
DIET: It is very agile and quickly flitting from one flower to the next in search of nectar, fruit or insects. The Japanese white-eye is omnivorous.
NESTING: Breeding pairs are monogamous. The nest is a woven structure hanging from a branch. About four white eggs are laid.
DISTRIBUTION: The native range of the Japanese white-eye is East Asia. It was introduced as a pet to Hawaii between 1929 and 1937. Since then it adapted so well that it is now considered as one of the most abundant birds on the islands.
CONSERVATION: The Japanese white-eye is widespread both in its native range and where it was introduced, therefore is not considered at risk. Its successful spread in Hawaii comes at a price though – out-competing native birds for sources of food (see reference below). There’s even consideration of culling them.
NOTES: This white-eye is a social bird, foraging in flocks, sometimes with other species.
