Bicknells Thrush

Bicknells Thrush

Latin name: Catharus bicknelli,
Conservsation status: vulnerable (population is decreasing)

One of the rarest birds in North America, the female may have up to four mates at one time.

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.


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.
Black-footed Albatros Black-footed Albatros
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.
Beluga Beluga
Belugas live in Arctic and Sub-Arctic waters. Impacts from climate change include: an increase in ship traffic as sea ice declines, oil exploration and extraction, fisheries by-catch, and disruption of the food web. As Arctic waters warm and currents change, the Humpback (a competitor) and the Orca (a predator) may move north and stay longer. Some Beluga populations are also threatened by hunting, pollution and habitat loss.
Western Glacier Stonefly Western Glacier Stonefly
Since 1960, the average summer temperature in Glacier National Park has increased by around 1 °C and glaciers have declined by 35%. By counting Stoneflies, scientists can determine how quickly glaciers are melting and the temperature of streams. In a two year search begun in 2011, scientists found the Stonefly in only one of the six streams it had previously occupied and discovered that it had retreated to two different streams at higher altitudes. Satellite data confirm that the world’s glaciers are declining, affecting the availability of fresh water for humans, animals and plants, and contributing to sea level rise.
