Bear Tracking in Yosemite Park

The Bear Management Team at Yosemite National Park has released a bear tracking map which allows you to follow the progress of three of the park's black bears. The Yosemite Bear Tracker Map displays the position of each bear and three tracks showing their movements over the last 30 days.

If you select a bear's marker on the map you can view details on how far it has traveled today and how far it has traveled over the last 30 days. The actual live positions of the bears is not shown on the map (the data is delayed) for the safety of the bears. As well as allowing you to follow the movements of three of the park's bears the map also shows the position of where bears were hit by vehicles in 2016.

Last year National Geographic attached cameras and tracking collars to two grizzly bears and two black bears inside Yellowstone National Park. They were then able to map the bears' movements inside the park and observe how they find food and interact with their environment.

A Bear’s-Eye View of Yellowstone allows you to watch footage from the four bear-cams and view the bears' tracks as they move around the park. As you scroll down this special interactive presentation from National Geographic the bears' tracks are updated on the map while the bear-cam footage from the currently displayed location plays on top of the map.

Highlights of A Bear's-Eye View of Yellowstone include a black bear taking a short-cut through some people's backyards, a cannibal bear feasting on another bear and a bear's encounter with a pack of wolves.

The Polar Bears International Bear Tracker map allows you to follow the progress of polar bears on and around Hudson Bay. The Bear Tracker map is tracking the movements of fourteen different polar bears.

Each of the polar bears has been fitted with a GPS collar which allows Polar Bears International to track the bears' movements and to show their locations on the Bear Tracker map (with a time delay for the bear's safety). The map also includes a sea-ice layer, which shows the extent of the current sea-ice extent on the bay.

The map includes a time-line which allows you to view the bears' movements since 2013. The time-line also shows the sea-ice extent for each day since 1 Oct 2013.
