The white-spectacled warbler (Phylloscopus intermedius) is a species of leaf warbler in the family Phylloscopidae. It is found in Asia from the eastern Himalayas to south-eastern China and southern Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It was formerly included in the Old World warbler family, Sylviidae.
The white-spectacled warbler was described by the English entomologist and ornithologist Frederic Moore in 1854 and given the binomial name Abrornis affinis. In 1898 the Irish ornithologist John David Digues La Touche described another bird to which he gave the binomial name Cryptolopha intermedia. These two taxa were subsequently considered to belong to the same species and were placed in the genus Seicercus. A molecular phylogenetic study published in 2018 found that neither Seicercus nor the closely related genus Phylloscopus were monophyletic. In the subsequent reorganization the two genera were merged into Phylloscopus which had priority under the rules of the International Commission on Zoological Nomenclature (ICZN). Before the merger, the nominate subspecies was Seicercus affinis affinis (Moore, F., 1854) but within the enlarged genus the name affinis was occupied by Tickell's leaf warbler Phylloscopus affinis (Tickell, 1833) which had priority. A new name zosterops was introduced to replace affinis, but under the rules of the ICZN the subspecies intermedius now had priority and became the nominate form.

Rare
Under 5% of wildlife watchers report a White-spectacled Warbler sighting in Royal Manas National Park on a given day, based on 69 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 388 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.
October
In that month about 20% of wildlife watchers report a White-spectacled Warbler in Royal Manas National Park on a given day, against under 5% in February to July, the lowest months. That is one of Royal Manas National Park's driest months, with about 130 mm of rain against 930 mm in July. August and September have too few records to rate.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most White-spectacled Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
2nd of 3
Of the 3 parks where we can rate White-spectacled Warbler sightings, Royal Manas National Park ranks 2nd at under 5%. The best odds are in Namdapha National Park (India, about 10%).
Same genus: Seicercus
The closest relatives of the White-spectacled Warbler that you can see in Royal Manas National Park (genus Seicercus) are Chestnut-crowned Warbler (about 10%), Gray-cheeked Warbler (about 10%) and Whistler's Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-spectacled Warbler is recorded against all the birds logged in Royal Manas National Park (69 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.
