There are two species of chorus frogs here in Canada: the Boreal Chorus Frog (Pseudacris maculata) and the Western Chorus Frog (Pseudacris triseriata). ), smooth and black. Their smooth (although a bit granular) skin varies in colour from green-grey to brownish. In Canada cold and snow is associated with this season. Males and females are identical in rather plain brown or grey plumage although females are slightly larger. Terri-Lee Reid   Conservation Researcher Canadian Wildlife Federation, Sean Brillant Ph.D. Some of these were introduced to the Aleutian Islands by fur trappers, who could charge more money for their unusually colored coats. In the northern hemisphere, about a third of insect species, such as the Wooly Bear moth, are able to partially freeze. Some can even lay their eggs deep underground where the soil doesn’t freeze or go dormant under the bark of the south-facing side of a tree to get more heat from sunlight! Austin-Smith. Queen bumblebees hibernate during the winter and the rest of the bees die. Chorus Frogs are about the size of large grape, about 2.5cm long on average, with a maximum of 4cm. This small Arctic rodent is found in Alaska, Canada and Russia. Royal Penguins One royal penguin . The shape and colour of the bill help in identifying the Trumpeter and Tundra swans in the field. There’s the serenity of the hushed woods, the snowy backdrop, and the solitude, which heightens all the senses. The body is rounded and thick with large feet, legs set back on the body, and a broad bill. Freeze-susceptible insects avoid freezing by supercooling. They empty the gut, reduce body water content, produce antifreeze (cryoprotectant) substances, for example glycerol, through anaerobic pathways and seek dry sites for the winter. The Common Raven is often mistaken for an American Crow in southern Canada and the United States. Each lateral tooth has cusps and together they always occur in a 2-3-3-2 cusp pattern. Around its mouth are small appendages called maxillipeds and mandibles which help direct food to the mouth and chew. A great number of birds have evolved to remain in Canada throughout the year. Currently, wolfs in Canada occupy about 90 % of the historic range. They also have a scaly skin, enabling them, as opposed to most amphibians, to live outside of water. The children can then make homes for them with the blocks or the toy animals can make homes for themselves! Freshwater turtles are reptiles, like snakes, crocodilians and lizards. Like the spotted owl, grizzly bears - one of the fiercest animals in North America - have been declared a threatened species in the lower 48 states in America and endangered in Canada. It has a worm or eel-like shape with two distinct dorsal fins and a small tail. Because the upper layer of soil is frozen and there is little to no precipitation in the form of rain, plants lack the required water and nutrients for growth. The outdoor areas in your neighbourhood don’t need to look empty in the winter. Because of their high metabolism, birds cannot hibernate. This is why lamprey are often unfairly called “aquatic vampires”. Mammals, like birds, are endothermic, meaning that they must sustain their metabolism in order to keep their body temperature high enough for survival. This diverse topography also means there’s a variety of animal species calling this country home. This usually provides some great dramatic play in the block area! Still, conifers do not grow during the winter. These bones are covered by horny scutes made of keratin (like human fingernails) or leathery skin, depending on the species. For deciduous trees and shrubs—and one species of coniferous tree, the Tamarack Larch—light levels in autumn become insufficient for photosynthesis to compensate for the energy cost of producing green pigments in leaves. Wings may span 3 m. Young of the year, or cygnets, can be distinguished from adults by their grey plumage, their yellowish legs and feet, and until their second summer of life, their smaller size.
