i was up in alaska out on the tundra and they had a ton of cranes there. i guess they are not the same kind?
Whooping Crane
So what you probably saw in Alaska were sandhill cranes.
But they're spectacular birds too. This august, I was in the Great Basin of Oregon and had the pleasure to watch more than 300 sandhill cranes circle overhead. The sound of "karooo karooo" was almost deafening.
Quite the experience.
See JoePro’s post at 18. The Alaskan cranes were probably not whooping cranes.
There might also be more information at the International Crane Foundation website: www.savingcranes.org
They’re located in WI...
The most abundant cranes are Sandhill cranes I believe. They migrate yearly and usually are mistaken for geese by people on the ground watching them.
