Fig. 1From: Both short and long distance migrants use energy-minimizing migration strategies in North American herring gullsMap of migration routes used by Herring Gulls, predicted by state-space models of tracking data. Breeding colonies are represented by a large red square. All individuals were captured at their breeding colony, except three individuals that bred in Newfoundland were captured during the winter in Massachussets, represented by a white star in panel B. Autumn migration tracks are shown in blue for Herring Gulls breeding in a) eastern Arctic (n = 8); b) Newfoundland (n = 12); c) Sable Island (n = 17); and d) the Bay of Fundy (n = 11). Stopover days are represented by yellow circlesBack to article page
