TL;DR: In this article, the authors identify important aggregations of seabirds in the North Atlantic to inform ongoing regional conservation efforts and identify a major hotspot associated with a discrete area of the subpolar frontal zone.

TL;DR: Day-length, the driver of daily and annual timing, is, however, fixed by latitude and date, which may restrict range-shift capacity, resulting in photic barriers to range-shifts.

TL;DR: In this paper, the authors used leg-mounted TDRs to infer activity budgets from diving seabirds, particularly for longer deployments, and validated the information obtained about bird behaviour with indepen- dent data by comparing interpretations of TDR data with visual observations.

TL;DR: Individual Hg concentrations during the non-breeding period for most of the seabird colonies were above 5 μg g-1 dry weight (dw), which is considered to be the threshold at which deleterious effects are observed, suggesting that some breeding populations might be vulnerable to non- breeding Hg exposure.

TL;DR: In this paper, the authors used remote time-lapse photography to collect population parameters at seabird colonies and found that photo-capture interval of one picture per hour during one murre breeding season showed a seasonal trend in attendance peaking in the mid chick-rearing period, a diurnal trend with a small peak at 07:00 hr and a larger peak at ca. 19:00hr.
