Figure 2.

Timing of the arrival of breeding thick-billed murres (median date of arrival as day of the year) at each colony relative to latitude. The full range in arrival dates is shown with error bars. Note the trend of later arrival with increasing latitude with the exception of an outlier at 60.8° N (Kitsissut in Qaqortoq), a colony influenced by the multi-annual pack ice that travels around the southern tip of Greenland.
