map about the distribution of Alca torda 

“Winters mostly offshore at sea, in W Atlantic off E Newfoundland as far as Flemish Cap (c. 700 km offshore), off Nova Scotia S regularly to North Carolina, and common on Georges Bank off New England. In E Atlantic, movements outside breeding season roughly similar to those of Uria aalge, but extends farther S. Overall, N populations move S or SW: Greenland and Labrador birds to offshore E Newfoundland and SW to Gulf of Maine and farther S, those from Barents and White Seas to Skagerrak, like Baltic breeders. N British birds first move to SW Norway and North Sea (young birds later to Bay of Biscay), whereas those from Irish Sea move S to Bay of Biscay and W Mediterranean. Most birds return to colonies from mid-Apr to early May in W Atlantic, except where ice persists longer (e.g. Labrador), and between early Mar and mid-Apr in E Atlantic, though some colonies are reoccupied by late Feb or earlier. Dispersal patterns complex, requiring further study of birds at sea outside breeding season on both sides of Atlantic.”
