Data from: When the sun never sets: diverse activity rhythms under continuous daylight in free-living arctic-breeding birds ...
Circadian clocks are centrally involved in the regulation of daily behavioural and physiological processes. These clocks are synchronized to the 24 h day by external cues (Zeitgeber), the most important of which is the light–dark cycle. In polar environments, however, the strength of the Zeitgeber i...
