Using a comprehensive set of tracking data from five seabird species in the North Atlantic and a model for estimating energy consumption, researchers have investigated how severe winter storms may impact the seabird community and eventually lead to seabird mass mortality.
Human activity in the coastal zone is increasing worldwide, including Norway. Aquaculture, kelp harvesting, fisheries, increasing boat and ship traffic present sources of disturbance and pose a variety of potential threats to seabirds.
By using a more than 100-year-old record of a puffin Fratercula arctica chick harvest on Iceland, researchers have found a relationship between ocean temperatures and production of puffin chicks.
How do seabirds find enough food to survive the darkness of winter? In a study on colonies in Great Britain, Iceland and Norway, researchers used geolocators to reveal that European shags adopt various strategies to handle the winter darkness.
The NorthWind research centre on wind energy launched its activities today with its first General Assembly.
130 years of catch data show that global warming is contributing to population decline in the world's largest puffin colony.
Changes in seabird breeding productivity reflect hemispheric differences in ocean warming and human use, and call out the need for policies that reduce the impacts of climate change on the world’s marine ecosystems.
This study signals the need for fisheries management to account for ecosystem constraints when setting catch limits in periods of low forage fish biomass.
Reduced availability of key prey forces adult puffins to fly further from their colonies to find food. Meanwhile, their chicks starve at the nests.
Using data from five different marine ecosystems, researchers have tested the hypothesis of predator‐pit dynamics for forage fish. By examining the consumption of fish by seabirds and the effect of such predation on fish population dynamics, they found that seabird-induced mortality of forage fish varies with fish abundance.
More than a quarter of the individual auks in which mercury levels were measured outside the breeding season exceeded the toxicity threshold.
Offshore oil rigs serve as a breeding refuge for Norwegian Black-legged Kittiwakes. Although they are few in number, these birds produce more chicks than kittiwakes in natural colonies along the coast, to the benefit of the impoverished
The Circumpolar Seabird Group under CAFF and the Arctic Council has proposed a conservation plan for the black-legged kittiwake Rissa tridactyla, a species which has been declining severely
Foraging shags and commercial kelp harvesters very often utilize the same marine areas.

Most seabirds have a long life span, delayed maturity andspread their reproduction across many years. This life history pattern makes seabird populations particularly sensitive to decreases in adult survival rates. Mass mortality events can there
Signe Christensen-Dalsgaard defends her academic thesis as part of the doctoral work at the Norwegian University of Science (NTNU): Drivers of seabird spatial ecology – implications for development of offshore wind-power in Norway
The genetic relationships between different populations of what was formerly known to belong to the species Leach’s storm petrel have been complicated for a long time. Researchers have now compared DNA from nearly 300 different individu
Recent Norwegian research shows that the black-legged kittiwake is surprisingly flexible when it comes to finding food for itself and its chicks. The ability to adapt makes this small gull robust to changes in the marine environment – t
