Every fall, the small town of Churchill, Manitoba, plays host to some famous guests. About 1,000 polar bears come to this small Canadian town on the western side of the Hudson Bay, waiting for the massive body of water to freeze over. Sound interesting? This year, you can see the bears' annual migration for yourself, via two live webcams.

Thanks to the efforts of three groups — explore.org, a philanthropic media organization, Polar Bears International, an organization focused on preservation and education of the animals, and adventure company Frontiers North — these live feeds are available to anyone with an Internet connection.

You can watch either of two views, the Tundra Buggy cam (above), which is attached to a moving vehicle, and the lodge cam, which is attached to a lodge on the edge of Hudson Bay. The best viewing times are 8 a.m. CST to 4 p.m. CST, and you'll see a great highlight reel if you click on the links outside of those viewing times.

After you've spied a few polar bears, go back to explore.org and check out the resource links — from how your daily actions can make a difference to high-resolution photographs and educational videos.

“The polar bears are among the most magical of our planet’s endangered species, and much like the tigers of Africa, have come to represent the many consequences of global warming and industrialization,” said Charles Annenberg Weingarten, filmmaker and founder of explore.org. “By providing a window into their worlds, we are giving people a chance to come together to cherish the bears and an opportunity to share their plight in a compelling way.”
