Before they develop competent endothermy, mammals and birds are sensitive to fluctuating
temperature. It follows that early life thermal environment can trigger changes to the …

Bird species on islands are strongly impacted by biological invasions, with the Icelandic
common eider (Somateria mollissima borealis) being particularly threatened. Down …

Forced convection can significantly influence the heat loss from birds and their offspring but
effects may be reduced by using sheltered micro-sites such as cavities or constructing nests …

Insulation is an essential component of nest structure that helps provide incubation
requirements for birds. Many species of waterfowl breed in high latitudes where rapid heat …

Effects of local weather on individuals and populations are key drivers of wildlife responses
to climatic changes. However, studies often do not last long enough to identify weather …

Breiðafjörður is an important molting, breeding, and wintering area for about 25% of the
Icelandic common eider (Somateria mollissima) population. However, feeding habits of …

Capsule Common Eiders at Rif in west Iceland commonly show joint nest attendance, which
may be an exaggerated behavioural response to the visual stimulus of many nests so close …

Animals that build structures have only two ways of obtaining their building materials:
collecting them from the environment or secreting them. We identify a clear pattern among …

Climate change studies have detected earlier spring arrival of breeding birds. However, first
nest dates (date first nests were found), which commonly provide the metric for earlier …

In the Common Eider Somateria mollissima, only females incubate the clutch over a period
of 25–28 days. Determining their schedule of nest absence, how long they are away, how …
