The common rock thrush (Monticola saxatilis), also known as the rufous-tailed rock thrush or simply rock thrush, is a species of chat that breeds in southern Europe across Central Asia to northern China. This species is strongly migratory, all populations wintering in Africa south of the Sahara. It is an uncommon visitor to northern Europe. Its range has contracted somewhat at the periphery in recent decades due to habitat destruction. For example, in the early 20th century it bred in the Jura Krakowsko-Częstochowska (Poland) where none occur today, but it is not considered globally endangered. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rufous-tailed Rock-Thrush is recorded against all the birds logged in Aigüestortes National Park (91 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.
