Ivory GullLatin 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
Koalas live in the woodlands of Australia. Thick fur and skin make it difficult for them to adapt to rising temperatures. Increased CO2 in the air produces less protein in the eucalyptus leaves, forcing the Koala to search for other sources of food and, in times of high heat, water. On the ground, the slow moving Koalas are prey to wild dingoes and domestic dogs, or are hit by cars as they cross roads. Their habitats are also being destroyed by drought, bush fires and development.
All populations of Ringed Seals are expected to be adversely affected by climate change because of dependence on sea ice and snow dens for breeding, protecting pups, moulting and resting. Early warming causes pups to separate prematurely from their mothers. As sea ice declines, other threats are fisheries by-catch, increased shipping, tourism and development. Seals are vulnerable to disease from heavy concentrations of pollutants that have accumulated in the Arctic food web.
Almost all Black Footed Albatrosses live in the Hawaiian Islands. Like all species of albatrosses that breed on low lying beaches and slopes, they are highly susceptible to sudden flooding from sea level rise and storm surges. Thousands each year are caught by longline fishing and they are also threatened by pollution and ingesting plastics that float in the ocean.
Tufted Puffins are threatened by sea level rise and storm surges which destroy habitats and breeding areas. In some areas of North America warming seas are causing the fish that the Puffins feed on to migrate farther north, making it difficult for them to find adequate food. Other threats are entrapment in fishing nets, oil spills, pollution, ingestion of plastic, human disturbance of breeding colonies and introduced predators such as rats and foxes.
