Swinhoe's white-eye (Zosterops simplex) is a bird species in the white-eye family, Zosteropidae. It is found in eastern China, Taiwan, north Vietnam, the Thai-Malay Peninsula, Sumatra and Borneo. Additionally, populations have also been introduced to Southern California, where their population has been expanding rapidly.
Swinhoe's white-eye was formally described in 1861 by the English naturalist Robert Swinhoe, who assigned it the binomial name Zosterops simplex. The genus Zosterops had been introduced by the naturalists Nicholas Vigors and Thomas Horsfield in 1827. The genus name combines the Ancient Greek words zōstēros meaning "belt" or "girdle" and ōpos meaning "eye". The specific epithet simplex is Latin meaning "simple" or "plain".
This species was previously considered a subspecies group of the Japanese white-eye (Zosterops japonicus), but based on the results of a molecular phylogenetic study published in 2018, it was elevated it to full species status.

With luck
About 10% of wildlife watchers report a Swinhoe’s White-eye sighting in San Diego on a given day, based on 2,306 verified sightings from GBIF citizen-science data. It is the 121st most-seen of the 386 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September to December
In those months about 10% of wildlife watchers report a Swinhoe’s White-eye in San Diego on a given day, against under 5% in January to August, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Swinhoe’s White-eye sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
40th of 45
Of the 45 cities where we can rate Swinhoe’s White-eye sightings, San Diego ranks 40th at about 10%. The best odds are in Hanoi (Vietnam, about 90%), Taichung (Taiwan, about 90%) and Zhuhai [Macau] (China, about 80%).
Same order: Passeriformes
The closest relatives of the Swinhoe’s White-eye that you can see in San Diego (order Passeriformes, Perching Birds) are American Crow (about 80%), House Finch (about 80%) and Black Phoebe (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swinhoe’s White-eye is recorded against all the birds logged in San Diego (2,306 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.
