It has been intentionally introduced to other parts of the world as a pet and as pest control, with mixed results. As one of the native species of the Japanese islands, it has been depicted in Japanese art on numerous occasions, and historically was kept as a cage bird.
The warbling white-eye was described by the ornithologists Coenraad Jacob Temminck and Hermann Schlegel in 1847 from a specimen collected in Japan. They coined the binomial name Zosterops japonicus. The English name "Japanese white-eye" was formerly used for Zosterops japonicus and what are now the Philippine subspecies of Z. japonicus were treated as a separate species, the "mountain white-eye" Z. montanus. A molecular phylogenetic study published in 2018 found that Z. montanus and several subspecies of Z. japonicus were conspecific, and they were therefore lumped together. They... Wikipedia →

With luck
About 10% of wildlife watchers report a Warbling White-eye sighting in Seoul on a given day, based on 474 verified sightings from GBIF citizen-science data. It is the 67th most-seen of the 231 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April and August–December
In those months about 10% of wildlife watchers report a Warbling White-eye in Seoul on a given day, against under 5% in January–March and May–July, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Warbling White-eye sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
12th of 12
Of the 12 cities where we can rate Warbling White-eye sightings, Seoul ranks 12th at about 10%. The best odds are in Fukuoka (Japan, about 60%), Busan (South Korea, about 60%) and Naha (Japan, about 60%).
GBIF citizen-science records
It is estimated from how often the Warbling White-eye is recorded against all the birds logged in Seoul (474 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
