Ivory Gull

Ivory Gull

Latin name: Pagophila Eburnea,
Conservsation status: endangered (population is decreasing)

Ivory Gulls build large nests of dry grass, moss, lichen and seaweed. In winter and early spring when food is scarce, foraging Caribou eat the nests. The gulls live in the high Arctic, rarely migrating any farther south than the Bering Sea.

Ivory Gulls are almost entirely dependent on sea ice and glaciers for nesting and food foraging. They feed on fish and shellfish that thrive near the edge of the ice, and on the remains of seals left by Polar Bears. Seal blubber is a source of heavy contaminants—Ivory Gull eggs show a higher concentration of mercury and pesticides than any Arctic sea bird. Other threats are illegal hunting and disturbance from diamond mining in the Canadian Arctic.


Other animals effected by climate change

Polar Bear Polar Bear
Polar Bears live only in the Arctic. Loss of sea ice has a critically adverse effect on Polar Bears. They hunt from the edge and build snow dens on the ice for resting and raising their cubs. Sea ice decline could open the Arctic to shipping and tourism, further disturbing Arctic habitats. Other threats are oil development and industrial pollution that reaches the Arctic through air and ocean currents.
Bicknells Thrush Bicknells Thrush
The breeding habitat of Bicknell's Thrush is primarily restricted to mountain spruce forests of Northeastern US and Canada. They winter in the Caribbean and spring migration north is cued by day length. If spring arrives early in the north and the Thrushes arrive at their normal time, the abundance of food—insects and fruit—would already have peaked. Warming temperatures also produce an abundance of spruce and fir cones—feeding and increasing the population of Red Squirrels, a main predator of eggs and chicks. Storms and hurricanes threaten the Thrush's tropical winter habitat. Pollution, logging and deforestation threaten their spring breeding and winter habitats.
American Pika American Pika
American pikas occupy talus—rock piles that accumulate at the base of a slope—at high elevations in western mountains. Pikas are thought to be a prime example of the potential effects of climate change because they are sensitive to warm temperatures and rely on insulation provided by snow to survive cold winter temperatures. However, several recent studies indicate that pikas can be resilient to each of these factors. Most pikas in the Sierra Nevada survived the winter of 2014, when there was almost no snowpack. Pikas persist in many hot localities as well, demonstrating their ability to cope with high temperatures.
Hawksbill Sea Turtle Hawksbill Sea Turtle
Climate change may affect Hawksbill Turtles in various ways because they live in different habitats at different stages of life: open ocean, beaches, lagoons and coral reefs. Rising sand temperature of nesting beaches produces more females and other abnormalities in baby turtles. Adults live primarily in coral reefs—threatened by rising ocean temperature and acidity. Since ancient times the Hawksbill has been exploited for its shell. They are also threatened from fisheries by-catch, development, and a high sensitivity to oil spills. The population has decreased by an estimated 80% in the last 100 years.
