The further north, the later the breeding
Data from SEAPOP's network of seabird colonies along the Norwegain coast and on Svalbard show that breeding phenology varies a lot between species, and depends on different factors.
Another poor breeding season for Norwegian seabirds
The report from the work on the SEAPOP key sites in 2015 is now published. Many species are struggling with low reproductive rates and population decline, and the estimates of adult survival are also depressing.
This is why nearly all Norwegian seabird colonies are in northern Norway
Why are bird cliffs distributed the way they are? Recent research reveals why seabirds along the Norwegian coast mainly breed in the northern part of the country.
Wind affects incubating eiders
Female common eiders incubate their eggs and chicks for weeks without eating. Does wind, temperature or humidity affect their energy expenditure most?
