Whooping Crane

The tallest bird in North America, the Whooping Crane is able to fly 500 miles a day. Some young cranes hatched in captivity learned their migration routes by following ultralight air craft.

Before 1800 there were an estimated 10–20,000 Whooping Cranes in North America. By 1941, because of hunting and habitat destruction, there were fewer than 20. There are now approximately 350–380 in the wild. The wild Whooping Crane population has only one winter habitat—a wildlife refuge on the Gulf Coast in Texas; and one spring breeding habitat—a prairie wetlands in Alberta. Severe storms, sea level rise, drought, industrial development and oil spills threaten these habitats. Another significant threat to young Whooping Cranes is colliding with power lines in their migration corridor.

Other animals effected by climate change

Tufted Puffin
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.

Adelie Penguin
In winter, the sun doesn't rise south of the Antarctic Circle. If Antarctic sea ice decreases and does not extend far enough to the north, Adélie Penguins, during their winter migration, may not be able to reach the sunlight needed to navigate, hunt and avoid predators—they won't dive in the dark. Other threats are oil pollution, fishing and disturbance of colonies from research stations and aircraft.

Monarch Butterfly
The annual North American migration of the Monarch is listed as a "threatened phenomenon." Climate related threats include: drought, storms, changes in precipitation and dependence on temperature to trigger migration and reproduction. The Monarch feeds and lays eggs exclusively on milkweed plants, so it is also highly vulnerable to herbicides and habitat destruction.

Emperor Penguin
In 50 years, the mean temperature of western Antarctica has risen nearly 3 °C—more than any other region—reducing the extent and thickness of winter ice. The Emperor Penguin is dependent on the ice for breeding, raising chicks and moulting. Less sea ice decreases zooplankton (krill) which feed on algae that grow on the underside of the ice. Krill are an important part of the food web for the Emperor and other Antarctic marine species.
