Polar bear wearing a GPS satellite video-camera collar
An 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
A 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. Avian keratin disorder (AKD) is a disease characterized by debilitating beak overgrowth and other abnormalities of keratinized tissues.

Lemon Creek Glacier in the spring
Lemon Creek Glacier is located in the high-latitude maritime region of Alaska, at the southernmost tip of the Juneau Icefield. Glacier observations began at this site in 1953.

USGS and FWS scientists collect body condition data on polar bear
USGS scientist Karyn Rode and USFWS biologist Michelle St Martin collect body condition data on a polar bear on the Chukchi Sea spring sea ice. USGS and FWS have collaborated on polar bear research in the Chukchi Sea since 2008 providing new insights into the status and health of the population and responses to changing sea ice conditions.

Scientist collecting samples on South Cascade Glacier
Scientist collection samples on South Cascade Glacier, northwestern Washington State. South Cascade Glacier located in a north-northwest facing valley near the crest of the Cascade Range in northwest Washington state. In 1959 scientists with the USGS began collecting mass balance data on South Cascade Glacier, now one of five "benchmark glaciers" in the US.

Black-capped Chickadee with a mildly deformed beak
A Black-capped Chickadee with an upper beak slightly longer than the lower beak. Avian keratin disorder (AKD) is a disease characterized by debilitating beak overgrowth and other abnormalities of keratinized tissues. Affected birds have difficulty feeding and preening and may suffer high rates of mortality.
