 == Distribution and habitat == 

 In the ""Distribution and habitat"" section there is a sentence that reads ""Except in Arctic habitats,[46] they are generally resident within their range for the whole year.""(the LLCN link is dead). This would seem to indicate that Arctic ravens are migratory birds. However, they winter year round in the Arctic. According to An Annotated Checklist to the Birds of Greenland (scroll down to page 50) in the last section it says, ""MOVEMENTS: Dispersive, resident or partially migratory (1 yrs). Even during winter Ravens are recorded in the high arctic."" Other sources confirm this ""Birds residing in the tundra throughout the year are very few and include species such as... raven"", ""Only the Common Raven, Snowy Owl and Rock Ptarmigan remain in the biome over winter, having the adaptations needed to do so"", ""The Common Raven breeds from the high Arctic islands (locally)... The Common Raven is mainly a permanent resident, wintering within the breeding range..."" and ""The North American breeding and wintering distribution of the Common Raven extends from Alaska and the high Arctic in the north..."".
