The Tibetan serin (Spinus thibetanus) or Tibetan siskin is a true finch species (family Fringillidae). The Tibetan serin was formerly placed in the genus Serinus but was assigned to the genus Spinus based on a phylogenetic analysis of mitochondrial and nuclear DNA sequences.
The first description of the species was by the British ornithologist Allan Octavian Hume in 1872 under the binomial name Chrysomitris thibetanus. In the 19th century, it was also referred to as the Sikkim siskin. At that time, the Lepcha of Sikkim referred to it as tŭk nyil nyón ('fierce wormwood').
Length (including the tail) of this species is around 12 cm (4.7 in). The Tibetan siskin lacks yellow panels on its wings in all plumages. Adult males have olive-greenish upper parts, yellow underparts, yellowish-green rumps, yellow supercilium and border behind ear-coverts. Wing and tail feathers of this bird species are broadly differentiated by a yellowish-green color. Adult females of this species have black streaking on darker greyish-green upper parts, more clearly defined wing-bars than their male counterparts, paler yellowish throats and black-flanked breasts...

With luck
About 10% of wildlife watchers report a Tibetan Serin sighting in Jiuzhaigou National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 98th most-seen of the 131 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Tibetan Serin in Jiuzhaigou National Park on a given day, against under 5% in April–May and July–December, the lowest months. That is one of Jiuzhaigou National Park's wettest months, with about 160 mm of rain against 15 mm in December. January to March have too few records to rate.

GBIF citizen-science records
It is estimated from how often the Tibetan Serin is recorded against all the birds logged in Jiuzhaigou National Park (8 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.
