Oh Canada!

Golden eagles were thought to be relatively rare in the hill and valley region bordering the mighty Mississippi river valley between Minnesota and Wisconsin. Most experts believed they were lost wanderers from the Rocky Mountain west. More interested birders, better equipment and knowledge of differentiating the big brown eagle from their immature Bald Eagles cousins, has begun to change that opinion. Goldens nest all the way up to the Arctic coast in Alaska and Western Canada. Their range maps show nothing along the western edge of Hudson Bay.
From late April to May, Whitey flew from western Wisconsin north to Duluth Minnesota at the westernmost tip of Lake Superior. Then he crossed into Ontario, Canada. And then he kept on going and going and going. Past Churchill on the southern shore of Hudson Bay. Then north along Hudson's western edge. He traveled 2,382 miles, averaging 72 miles per day. His longest one-day flight was 193 miles. From late May to early October, Whitey spent the summer wandering over an immense area of Nunavut — from the northern shore of Hudson Bay to a lake above the Arctic Circle. It had been a migration of astonishing proportions and came as a total surprise to everyone. Or as one of the experts said, "Wow!" And then on October 7, he turned and headed back toward his winterhome By early November, Whitey was back in southwestern Wisconsin after a 26-day, 1,750-mile migration.
Mark Martell, director of bird conservation for Audubon Minnesota said the finding has conservation implications. "These birds are cool, just cool," Martell said. "Here’s this huge, predatory bird that we weren’t even aware was here on a regular basis."
Their presence raises a serious issue — how best to protect them —. But more information is needed first. 
Whitey repeated his epic journey several times.  Other captured Golden Eagles later flew similar tracks north with some variations included on which veered north east crossing Ontario to enter Quebec.

  5. Yes, if we see a golden brown bird like that down here we assume that it is an immature bald eagle. It is a beautiful bird. I have seen them in zoos years ago. I hope they don’t put them in cages anymore.

  6. New technology allows us to discover much more about many different species and where they live.

  9. Hi Ray, This is just very interesting to hear about Whitey and his travels thanks to the satellite link up. Wow is the word! Looking at that range map it appears we might see a Golden out here but I have not. It is on my wish list! :-) Thanks for these informative posts. Hope you have a fine weekend ahead! John
