A new study from The Auk:
Ornithological Advances presents some of the best evidence that Whiskered
Auklets are an outlier in the auklet family by not migrating and instead
staying close to "home" (their breeding colonies) year-round. Most
migratory birds lead two opposite lifestyles in the same year. During the
breeding season a bird's location is constrained and their habits are
repetitive given a nest full of chicks that require food, warmth, and
protection. For some birds it is the only time they congregate or otherwise
come together. Comparatively, during the non-breeding season their only true
task is to survive. Whether migratory or residential, as long as the bird makes
it back to the breeding grounds to reproduce, they can go almost wherever they
want. Whiskered Auklets are consistent through the year though and don't wander
far at all.
