Fit is fat: winter body mass of Atlantic Puffins Fratercula arctica
Anker-Nilssen, Tycho; Harris, Michael P.; Jensen, Jens-Kjeld (Journal article; Peer reviewed, 2018)Capsule: Atlantic Puffins Fratercula arctica from Scottish and Norwegian populations were significantly heavier in winter than when rearing chicks. Aims: To compare body masses of Atlantic Puffins on their wintering grounds ... -
Moult location and diet of auks in the North Sea inferred from coupled light-based and isotope-based geolocation
Glew, Katie St. John; Wanless, Sarah; Harris, Michael P.; Daunt, Francis; Erikstad, Kjell E; Strøm, Hallvard; Trueman, Clive N. (Journal article; Peer reviewed, 2018)Many pelagic seabirds moult their feathers while at sea, which is an energetically costly behaviour. Mortality rates during moult can be high, so spatial and trophic ecology during this critical period is important for ... -
Multi-colony tracking reveals spatio-temporal variation in carry-over effects between breeding success and winter movements in a pelagic seabird
Bogdanova, Maria I.; Butler, Adam; Wanless, Sarah; Moe, Børge; Anker-Nilssen, Tycho; Frederiksen, Morten; Boulinier, Thierry; Chivers, Lorraine S.; Christensen-Dalsgaard, Signe; Descamps, Sébastien; Harris, Michael P.; Newell, Mark; Olsen, Bergur; Phillips, Richard A.; Shaw, Deryk; Steen, Harald; Strøm, Hallvard; Thórarinsson, Thorkell L; Daunt, Francis (Journal article; Peer reviewed, 2017)Carry-over effects, whereby events in one season have consequences in subsequent seasons, have important demographic implications. Although most studies examine carry-over effects across 2 seasons in single populations, ... -
Open Access Sympatric Atlantic puffins and razorbills show contrasting responses to adverse marine conditions during winter foraging within the North Sea
St.John Glew, Katie; Wanless, Sarah; Harris, Michael P.; Daunt, Francis; Erikstad, Kjell Einar; Strøm, Hallvard; Speakman, John R.; Kürten, Benjamin; Trueman, Clive N. (Movement Ecology;, Peer reviewed; Journal article, 2019)Background: Natural environments are dynamic systems with conditions varying across years. Higher trophic Level consumers may respond to changes in the distribution and quality of available prey by moving to locate New ...
