The collared grosbeak (Mycerobas affinis) is a species of finch in the family Fringillidae. Its range encompasses the northern regions of the Indian subcontinent, mainly the Himalayas, along with some adjoining regions. It is found in Bhutan, India, Myanmar, Nepal and Thailand. Its natural habitat is mountainous deciduous or mixed forests.
The collared grosbeak may be the largest species in the diverse finch family, but several other species, including others in the genus Mycerobas, may rival it in size. The species can range in length from 22 to 24 cm (8.7 to 9.4 in). The body mass of two males was reportedly 69 and 72 g (2.4 and 2.5 oz), while a single female weighed 83 g (2.9 oz). Among standard measurements, the wing chord is 12.1 to 13.8 cm (4.8 to 5.4 in), the tail is 8.7 to 9.7 cm (3.4 to 3.8 in), the bill is 2.7 to 2.9 cm (1.1 to 1.1 in) and the tarsus is 2.6 to 2.9 cm (1.0 to 1.1 in). Adult males are glossy black on the head, upper-wings and tail. Contrasting with the black head, the collar is an earthy brownish color. The rest of the male's plumage is a rich, deep yellow. The female is olive-green on back and yellowish below with no black about the face... Wikipedia →

Rare
Under 5% of wildlife watchers report a Collared Grosbeak sighting in Langtang National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 213th most-seen of the 225 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Collared Grosbeak in Langtang National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Collared Grosbeak 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 2
Of the 2 parks where we can rate Collared Grosbeak sightings, Langtang National Park ranks 2nd at under 5%. The best odds are in Jiuzhaigou National Park (China, about 20%).
GBIF citizen-science records
It is estimated from how often the Collared Grosbeak is recorded against all the birds logged in Langtang 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.
