Industrial fisheries are starving seabirds like penguins and terns by competing for the same prey sources, new research from the French National Center for Scientific Research in Montpellier and the Sea Around Us initiative at the University of British Columbia has found.
Bad weather is bad news, also for the red-listed kittiwake. New research reveals that wind conditions combined with the availability of different prey species are determinants of chick production in this seabird.
For millennia, ecosystems in Greenland and throughout the Arctic have been regulated by seasonal changes that govern the greening of vegetation and the migration and reproduction of animals. But a rapidly warming climate and disappearing sea ice are upending that finely tuned balance.
Mass die-offs and breeding failures, now ongoing for years, have marine biologists worried that this is a new normal caused by climate change.
'Shocking' decline of Arctic skua revealed in study. Conservation scientists say a lack of food is behind the drop in the UK population.
Wild and free. That’s the new life for a herd of 31 plains bison which have finally been fully reintroduced to the backcountry of Banff National Park for the first time in 140 years.“These are not a captive display herd.
Bird Notes columnist Julian Hughes of RSPB Conwy reveals how the Snowy Owl got twitchers in a flap, and outlines 11 birding events in the coming days
In the fall of 2014, West Coast residents witnessed a strange, unprecedented ecological event. Tens of thousands of small seabird carcasses washed ashore on beaches from California to British Columbia, in what would become one of the largest bird die-offs ever recorded.

Coastal sand ecosystem returning to health after 1.5 years of work
The studies have established that even in places where plant diversity and abundance have improved, insect numbers still declined.
On a remote Alaskan sandbar, under the watchful eye of a devoted scientist for more than four decades, climate change is forcing a colony of seabirds into a real-time race: evolve or go extinct.
Serious and unusual outbreaks of illness from eating raw or undercooked walrus to call attention to the risks.
An assistant professor at the University of Alaska–Fairbanks suspects that changes seen in the auklet population on Little Diomede may be related to changes in climate.
Since the mid 1990s, the number of black brant (Branta bernicla nigricans; brant) nests on the Yukon-Kuskokwim Delta (YKD), Alaska, USA, the historically predominant breeding area of brant, has declined steadily.
In the Arctic, brown bears (Ursus arctos) are expanding their range northward, in some cases competing with and even mating with polar bears (Ursus maritimus). Beavers (Castor canadensis) have been found as far north as the coast of the Beaufort Sea. The list includes mammals, amphibians, fish and insects.
The latest research shows that diminishing Arctic sea ice caused by climate change is forcing some species to travel further to find food or look for alternative food sources.
Did you know there are two different species of hummingbirds in the Vancouver area? The rufous hummingbird is a tiny orange-red hummer that visits B.C. each summer and winters in Mexico, while the slightly larger maroon-and-green Anna’s hummingbird is here all year.
Populations of marine wildlife have plummeted by a half on average over the past 40 years with some species suffering far greater declines as a result of habitat loss, overfishing, rising sea temperatures and worsening ocean acidity, a major report has found.
Right now, a lethal strain of bird flu is wreaking havoc in the Lower 48. It’s clear that migrating flocks have something to do with spreading the illness between farms and across continents -- but exactly what is still fuzzy. A remote spot in Southwest Alaska may hold some clues. Download Audio
When wild birds are a big part of your diet, opening a freshly shot bird to find worms squirming around under the skin is a disconcerting sight. That was exactly what Victoria Kotongan saw in October, 2012, when she set to cleaning two of four spruce grouse (Falcipennis canadensis) she had taken near her home in Unalakleet, on the northwest coast of Alaska.
