Migrating seabirds take advantage of favourable winds
15. January 2024

SEATRACK-data used to study the relationship between wind patterns and migrating movements.

New status indicator for seabird populations
4. January 2024

New indicator for status of seabirds combines population size, adult survival and breeding success.

Variable foraging patterns among black guillemots
24. October 2023

With an aim to identify the characteristics of the best foraging areas for black guillemots (Cepphus grylle), researchers in SEAPOP have studied foraging behaviour and habitat use of black guillemots at three breeding locations along the Norwegian coast. Although differences in foraging activity and habitat use were found, one parameter in particular stood out as the most important.

New assessment of the mercury contamination and the potential health risk to Arctic seabirds and shorebirds
24. May 2023

Mercury is known to have an adverse effect on animal wildlife, and mercury contamination has increased through anthropogenic inputs. A new study examines the mercury exposure and the potential health risks for 36 Arctic seabirds and shorebirds.

New study examines the breeding phenology of 51 seabird populations across the North Atlantic.
28. March 2023

Successful breeding is crucial, but climate change can make timing of breeding more demanding. A new study including data from several colonies monitored throughout the SEAPOP programme has now examined how seabirds adjust their breeding phenology.

Raising offspring accelerates senescence in the Atlantic puffin
6. March 2023

Negative trends for populations with low productivity can be somewhat mitigated by adults living longer.

Are storms killing seabirds?
21. October 2022

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.

How to predict the foraging habitat of European shags
18. May 2022

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.

Changes in ocean temperatures contribute to a puffin population decline
16. February 2022

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.

Chase the sun or catch prey in twilight?
26. January 2022

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.

Major wind research centre kicks off its activities
16. June 2021

The NorthWind research centre on wind energy launched its activities today with its first General Assembly.  

Puffin hunting in Iceland gives a unique insight into climate effects
4. June 2021

130 years of catch data show that global warming is contributing to population decline in the world's largest puffin colony.

Seabirds ring the alarm
27. May 2021

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. 

Seabirds consume higher proportions of fish stocks when prey abundance is low
9. April 2021

This study signals the need for fisheries management to account for ecosystem constraints when setting catch limits in periods of low forage fish biomass.

GPS-tracking of chick-rearing puffins reveals causes of population decline
26. March 2021

Reduced availability of key prey forces adult puffins to fly further from their colonies to find food. Meanwhile, their chicks starve at the nests.

Seabirds consume higher proportions of fish stocks when prey abundance is low
9. February 2021

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.

Feathers reveal mercury contamination in alcids in the Arctic
4. December 2020

More than a quarter of the individual auks in which mercury levels were measured outside the breeding season exceeded the toxicity threshold.

Kittiwakes find refuge on offshore oil rigs
19. November 2020

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

Seabird experts in CAFF propose a new kittiwake conservation plan
4. November 2020

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

Seabirds and kelp harvest – conflict or harmony?
18. September 2020

Foraging shags and commercial kelp harvesters very often utilize the same marine areas.
