QUEBEC BIODIVERSITY exhibit

Surviving the winter

Fur

The fur of mammals protects them from the cold of Quebec winters. Their body is insulated from the cold dry air that surrounds them by the thick fur layer. Fur is also important because it allows some animals to camouflage themselves within the white snow, such as the polaR bear. In the summer, some species such as the Arctic fox, shed their fur so that they can camouflage in the darker environment of the summer tundra.

Feathers

The birds that live in the Arctic conditions of Quebec also adapted to living in the cold. For example, birds such as the Snowy owl and the Willow ptarmigan have evolved feathers to cover the legs and feet, which insulates them like the rest of their body to prevent heat loss. The ptarmigan also sheds its white winter feathers for a darker summer plumage to better hide from predators in the tundra.

Beak diversity

Birds have evolved to feed on many different types of food items. The diversity of feeding habits can be determined by the type of beaks they have. Piscivorous species will have long and slender beaks to harpoon fish. Carnivorous species will have raptorial beaks to tear flesh from their prey. Insectivorous species will have short and narrow beaks to catch insects. Granivorous species will have short and bulky beaks to break nuts and seeds.

Predation

Predators have evolved several features to increase their chance of catching prey. Birds of prey possess strong talons to not only catch their prey, but also to hold it down while tearing pieces off with its raptorial beak. Mammalian predators have evolved similar features, such as strong claws to catch their prey and large canine teeth to tear off pieces of muscle and soft tissue.

Conservation

The museum holds many specimens of threatened, endangered and even extinct species that lived in Quebec. These specimens allow visitors to observe the species that have been affected by humans. Some of these are species at risk and some are species that are already extinct such as the Passenger Pigeon.
