Images from polar bear collar cameras document activity
through the summer season, and inform a new research
study by USGS and Washington State University.
Polar bears exhibited a wide range of behavioral responses
while on land from resting 98% of the time to travelling up
to 330 km (205 miles) over 3 weeks and spending up to 40%
of their time foraging on berries.
Ultimately, all the bears, except one individual who found a
marine mammal carcass on land, lost about 1 kg (2.2 lbs) per
day on average, which highlights that none of these behavior
strategies were beneficial for extending the period in which
polar bears can survive on land.
