Polar bear wearing a GPS satellite video-camera collar
Polar bear wearing a GPS satellite video-camera collarAn adult female polar bear on the sea ice wearing a GPS satellite video-camera collar. GPS video-camera collars were applied to solitary adult female polar bears for 8 - 12 days in April, 2014-2016. These collars enabled researchers to understand the movements, behaviors, and foraging success of polar bears on the sea ice.

Black-capped Chickadee with lower elongated and upper curved beak
Black-capped Chickadee with lower elongated and upper curved beakA Black-capped Chickadee with a severely deformed beak where the upper beak is elongated and curved down while the lower beak is elongated and straight. Over the past 26 years, Alaskans have witnessed a startling increase of beak deformities among Black-capped Chickadees and other species of resident birds.
