PORTLAND -- A federal scientist has fitted an Oregon Zoo polar bear with a high-tech monitoring device to gather information about how it walks, eats and swims.
Anthony Pagano of the U.S. Geological Survey says the observations of Tasul should help scientists get a better fix on the behavior of wild polar bears.
The bears are losing habitat to climate change, which is shrinking the sea ice. But they're hard to study in their remote, harsh environment.
The Oregonian reports that the bear is wearing a collar for a few hours a day. It has two accelerometers, which turn common behaviors into electronic signals.
The bear is also being put on video. The scientists say that's part of creating a digital library of polar bear behavior.
