Martens's warbler (Phylloscopus omeiensis), also known as Omei warbler or Emei Shan warbler, is a species of Old World warbler in the family Phylloscopidae (or Sylviidae). It was first described in 1999. It is found in China and Myanmar. Its natural habitats are temperate forests and subtropical or tropical moist montane forests.
Martens's warbler was initially placed in the genus Seicercus. A molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic. In the subsequent reorganization the two genera were merged into Phylloscopus which has priority under the rules of the International Commission on Zoological Nomenclature.

Rare
Under 5% of wildlife watchers report a Martens's Warbler sighting in Khao Yai National Park on a given day, based on 73 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 170th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December and January
In those months about 10% of wildlife watchers report a Martens's Warbler in Khao Yai National Park on a given day, against under 5% in February to November, the lowest months. Those are among Khao Yai National Park's driest months, with about 20 mm of rain a month against 330 mm in September.
2nd of 3
Of the 3 parks where we can rate Martens's Warbler sightings, Khao Yai National Park ranks 2nd at under 5%. The best odds are in Doi Inthanon National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Martens's Warbler is recorded against all the birds logged in Khao Yai National Park (73 verified sightings from 2019 to 2026), 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.
