Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed based on sighting reports submitted by birdwatchers to the ebird.org website. The global distribution of the Carrion Crow is available HERE . Carrion Crows are found mainly in western and northern Europe, but there is a scattered population throughout central to eastern Asia as well, in particular in Korea and Japan. In Europe Carrion Crows are a sedentary species that is found only in central and western Europe, to the West of a line of the rivers Oder and Neisse in Germany that, in its continuation, wraps around the eastern edge of the Alps. In the North and West their range extends to southern Denmark and central Scotland. They are NOT found in the northern Scottish highlands or or Ireland. In the South-west their range extends to roughly the northern half of Iberia. Part of the Carrion Crow population that usually lives at high altitude in the Alps spends the winters in the Po River flatlands of northern Italy. Carrion Crows can live in a variety of habitats. If not desperate for a feed, e.g. in winter time, as nest robbers they are usually wary, also of humans. In winter they are often found in agricultural areas and around carrion (including road kill).

Sightings Click here for sighting information H. Dahlem-Senger reports spotting Carrion Crows in Rüdesheim, Hessen, Germany, in November 2016. They are found in the same area semi-regularly since then. M. Thomas reports finding Carrion Crows in Eltville, Hessen, Germany, in February 2017. J. Pires reports finding Carrion Crows regularly in different areas in Portugal, and in particular from the Tejo estuary to Mora, Evora, Portugal. M. Eaton found Carrion Crows in Hyde Park, London, England, in September 2019. Carrion Crows were also found by H. Dahlem-Senger near Oberkirch, Baden-Württemberg, Germany, in September 2020.
