Map of bird movement

Detailed Description

A. Arrows show generalized movements of birds in particular flyways. Red arrows show general movements in the East Atlantic Flyway and yellow arrows show general movement in the North American Atlantic Flyway. Most birds use only portions of the flyways, which are determined mostly by species and by origin of breeding populations.

B. Red dots show the locations of where birds were sampled in the study. Reykjavik is shown for reference. Samples from some locations (Breiðafjörður and Selfoss) were obtained over a larger area than shown because samples were provided by hunters and fishermen within the region.
