The red-billed chough, Cornish chough or simply chough ( CHUF; Pyrrhocorax pyrrhocorax) is a bird in the crow family, one of only two species in the genus Pyrrhocorax. Its eight subspecies breed on mountains and coastal cliffs from the western coasts of Ireland and Britain east through southern Europe, North Africa and Middle East to Central Asia, India and China.
This bird has glossy black plumage, a long curved red bill, red legs, and a loud, ringing call. It has a buoyant acrobatic flight with widely spread primaries. The red-billed chough pairs for life and displays fidelity to its breeding site, which is usually a cave or crevice in a cliff face. It builds a wool-lined stick nest and lays three eggs. It feeds, often in flocks, on short grazed grassland, taking mainly invertebrate prey.
Although it is subject to predation and parasitism, the main threat to this species is changes in agricultural practices, which have led to population decline, some local extinction and range fragmentation in Europe; however, it is not threatened globally. The red-billed chough, which derived its common name 'chough' from the jackdaw, was formerly associated with fire-raising, and has links with Saint Thomas Becket and Cornwall. Wikipedia →

Possible
About 20% of wildlife watchers report a Red-billed Chough sighting in Langtang National Park on a given day, based on 96 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 42nd most-seen of the 225 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Red-billed Chough in Langtang National Park on a given day, against about 10% in January–February, June and November, the lowest months. That is one of Langtang National Park's wettest months, with about 390 mm of rain against 10 mm in November.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Red-billed Chough sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 17
Of the 17 parks where we can rate Red-billed Chough sightings, Langtang National Park ranks 10th at about 20%. The best odds are in Hemis National Park (India, about 70%), Picos de Europa National Park (Spain, about 60%) and Ordesa y Monte Perdido National Park (Spain, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Red-billed Chough is recorded against all the birds logged in Langtang National Park (96 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.
