Why are some birds more intelligent than others?

If you’ve ever seen a starling peck open a garbage bag or a grackle steal your dog pellets, you get a sense that some birds have learned to take advantage of new feeding opportunities – a clear sign of their intelligence. Scientists have long wondered why certain species of birds are more innovative than others, and whether these capacities stem from larger brains (which intuitively seems likely) or from a greater number of neurons in specific areas of the brain.

Arctic seabirds are less heat tolerant, more vulnerable to climate change

The Arctic is warming at approximately twice the global rate. A new study led by researchers from ��ֱ�� finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.

“We discovered that murres have the lowest cooling efficiency ever reported in birds, which means they have an extremely poor ability to dissipate or lose heat,” says lead author Emily Choy, a Postdoctoral Fellow in the Natural Resource Sciences Department at ��ֱ��.

Muscle structure and body size predict the athletic performance of Olympic athletes, such as sprinters. The same, it appears, is true of wild seabirds that can commute hundreds of kilometres a day to find food, according to a recent paper by scientists from ��ֱ�� and Colgate universities published in the Journal of Experimental Biology.

Bat-winged dinosaurs that could glide

Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, according to a new study led by an international team of researchers, including ��ֱ�� Professor Hans Larsson. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years.

Biologists now have a better idea of the origin of birds and the evolution of flight, two iconic events in the history of life on earth, thanks to work by a group of international scientists including a ��ֱ�� professor. In updating the evolutionary tree, the team’s findings show some dinosaurs could fly before they evolved into birds, and many others were experimenting with powered flight.

There’s less ice, more capelin and lots of hungry polar bears

Climate change in the eastern Arctic has already altered the travel, diet and safety of some of the most numerous birds in the circumpolar world: thick-billed murres, known as akpait in Inuktitut.

These and other changes are likely to continue, says Allison Patterson, a ��ֱ�� graduate student [with Professor Kyle Elliott] who has tracked the habits of these black-and-white birds on Hudson Bay’s Coats Island, known as Akpatordjuark in Inuktitut.
