The loudest sign of spring in southern Yukon is the return of the trumpeter swans. Thousands take a rest and refuel in M'Clintock Bay. As the CBC's Cheryl Kawaja reports, this year, they're about a week ahead of schedule.

A very unusual visitor has been spotted in Burgeo, and the Black Vulture is causing a stir among birdwatchers, who believe it may have been blown to Newfoundland by strong winds.

The Nova Scotia Department of Natural Resources says it was a Canada goose. When found in Grand Désert, the wild goose had the H5N1 strain of influenza and was showing symptoms. She died 24 hours later.

It's not the first time snow geese have died in large numbers in western Nunavut. The cause of this event is under investigation, but overpopulation could have played a role, says the Canadian Wildlife Service.

Thirteen of the state's 14 confirmed mammal deaths have occurred in the past month.
