(Lepus townsendii) Family: Leporidae Description: As an adult, this is the largest member of the Lagomorph family. It measures 55 to 64cm long and weighs 2.7 to 4.1kg. It is characterized by black-tipped ears and long hind legs. In summer it is grayish-black, in winter it is all white except for the tips of the ears. Females may be slightly larger than males. Distribution: Quite common in the south half of Alberta in Grassland areas. Intersting Notes: The more common name for the White-tailed Prairie Hare is the Jackrabbit. Despite this name, this is a true hare. Hares have long ears and long legs and can run great distances and young are born fully furred with their eyes open and are able to hop. Rabbits have shorter ears and legs and young are born naked, blind and helpless. Hares also nest in clumps of grass above the ground, rabbits use burrows dug by other animals.
Members of the Order Lagomorpha have two sets of front incisors, one pair directly behind the
other (Rodents have only one pair). Like rodents however, these teeth grow throughout their
lives and must be continually sharpened by gnawing. Lagomorphs geneally have a very short or
no tail and well developed ears.
(Tamiasciurus hudsonicus) Family: Sciuridae Description: The Red Squirrel is a medium-sized member of the family. They are 30 to 33cm long from nose to the tip of the tail (11 to 14cm of that being the tail). An adult red squirrel weighs 185 to 335g Females are slightly larger than males. The fur changes colour seasonally. In summer it is rusty red on top and grayish-white on the belly. There are prominant white crescents above and below the eyes. Distribution: Red Squirrels are found throughout much of northern and western Alberta. They are seldom seen in the grasslands.
Intersting Notes: Red Squirrels are born naked and blind and are weaned at eight
weeks of age. Red squirrels nest undergroung in the Rockies and in trees elsewhere in
the province. Pine and spruce seeds make up the bulk of the squirrel's diet, but they also
eat nuts, berries, mushrooms, meat, sap, young birds and bird eggs. Squirrels often cache
food in large quantities. They have favorite feeding spots where they eat spruce and pine seeds,
discarding the cone stems and scales which are piled up at the base of a tree. This pile is
called a midden. Red squirrels do not hibernate, but stay close to their stashed
away food supply all winter and will venture out for short periods of time to feed.
(Castor canadensis) Family: Castoridae Description: The beaver is North America's largest rodent measuring 100 to 125 cm long and weighing 16 to 30kg. They are semi-aquatic, with short legs, a large head with small eyes and ears. It's most distinguishing characteristic are large webbed hindfeet and a large broad, flattened scaly tail. They have redish-brown to dark brown gaurd hairs with a dense, gray underfur. Distribution: Beavers can be found province-wide and are quite common in most areas although there are some local areas of Alberta where they are scarce or absent.
Intersting Notes: The beaver is the nationl animal symbol of Canada. When it
was first discovered by European settlers, it was a major economic resource and was
hunted and trapped extensively for its fur. With reduced demand for its pelts the
beaver has made a gradual comeback and is now considered a pest in some areas due to
its propensity to cut down trees for its dams and food.
(Erethizon dorsatum) Family: Erethizontidae Description: With its arsenal of up to 30000 sharp, barbed quills on its back, side and tail, the porcupine is not likely to be mistaken for any other animal. They are about 71 to 90cm from nose to tail and wiegh about 6.5 to 9.5 kg. There are no quills on the soles of feet and few on the underside. Distribution: The porcupine can be found throughout Alberta.
Intersting Notes: Contrary to popular belief, the porcupine can not "throw" its
quills. The ends of these specialized hairs are barbed, which if touched, will pull out
of the porcupine and stick into any potential predator. The porcupine does have some
muscular control over its quills and will raise them if it feels threatened and it will
lash its tail towards any predator. Porcupines are actually very laid back animals and
move slowly throughout their environment without too much worry about predators.
(Vulpes vulpes) Family: Canidae Description: The red fox is about 94 to 110 cm long from nose to tail, stands about 35cm at the shoulder and weigh anywhere from 3.6 to 4.6 kg as adults. The fur is a rusty or orange-red but may also be black, sandy or even silver colored. The throat and underparts are generally white and the legs, feet, and back of the ears are generally black. The tip of the tail is also white - a distinguishing mark of the red fox. Distribution: The red fox may be found throughout Alberta, but is more common in southern regions of the province than in northern parts
Intersting Notes: The red fox is a very efficient predator of rabbits, mice and
other rodents. When hunting mice and ground squirrels the fox will slowly stalk the prey
and pounce up to 4m trying to pin them with its front feet. If hunting rabbits it a
pure chase. Foxes have a great ability to adapt to new environments and have succeded
quite well in human-created habitats.
(Mustela erminea) Family: Mustelidae Description: The ermine is a medium-sized member of the weasle family. Members of this family are long and slender with a small face and short ears. Male ermines are considerably larger than females. Males are about 30 to 34cm long and weigh about 135 to 170g. Females are about 22 to 26cm long and weigh about 55 to 90g. During summer ermines are chocolate brown above and white below, during winter they are all white except for the tips of their tails. Distribution: Ermines can be found in most of Alberta with the exception of the southeast portion of the province. They are more common further north in their range than in the southern reaches, and are the most common weasle in the Rocky Mountains.
Intersting Notes: The ermine is sometimes called the "Short-tailed weasle" or "stoat".
They are constantly hunting, eating as much as one-third their weight daily. They mainly
prey upon small rodents, birds, eggs, fish, frogs and insects and may even take down
prey items several times their size scuh as hares. Ermines are in turn preyed upon by
hawks, owls, and foxes. Humans are their most serious threat hunting them for their pelts.
(Mephitis mephitis) Family: Mustelidae Description: The skunk is not likely to be mistaken for any other animal (and if it is it will only happen once). The skunk has a stout body with short legs, and a small head and ears. They are black with a broad white stripe along the head which splits in two and runs either side of its back and merges again along the length of the tail. They are about 65 to 70cm long and weigh about 2.5 to 4kg. Distribution: Striped skunks may be found province-wide in a variety of different habitats
Intersting Notes: The striped skunk has made the use of chemical defense an artform.
The skunk's scientific name, Mephitis, loosely translates from Latin as "noxious
odor". The smell comes from a yellowish, oily liquid with a high sulfur content which
is secreted from two small anal glands at the base of its tail. The smell is so potent
it can be detected by humans in concentrations of less than one part per trillion. The
skunk, however, only uses this chemical weapon as a means of last resort offering any
potental predators several advance warnings including feet stomping and raising its
tail in warning.
(Felis concolor) Family: Felidae Description: The cougar is the largest member of the cat family found in Alberta. It has a compact, rounded muscular body with a small head, round eyes and small ears. Males are somewhat larger than females. They have large feet and a tawny or redish-brown coat with short thick hair. Males measure 2 to 2.3m in length and weigh 60 to 82kg. Females measure 1.8 to 2m in length and weigh 36 to 52kg. Distribution: At one time, this cat ranged over much of the Americas from parts of the Northwest Territories to Patigonia. Excessive persicution and habitat loss has reduced its range to a tiny fraction of what it once was. In Alberta cougars are basically restricted to the Rocky Mountains and foothills where there is little, if any, human contact -- although there have been rare sightings in other regions of the province
Intersting Notes: The cougar has a pletora of other common names including "mountain
lion", "puma", "panther", and "Indian devil". Its long, thick tail is used as a counterbalance
when running. It also lacks the tufted ears seen in Alberta's two other cats, the lynx and bobcat.
(Lynx canadensis) Family: Felidae Description: The Canada Lynx is a long-legged, short-tailed cat with large feet, very conspicuous black-tipped ear tufts. It has a large ruff of fur surounding its face and a short, bobbed, black-tipped tail. They are light gray in winter and brownish in summer. Males are slightly larger than females. The Canada Lynx is about 80 to 100cm long and weighs about 8 to 11kg. Distribution: The Canada Lynx is fairly common and can be found in the western foothills and mountians, and northern forested areas of Alberta. They are rare to uncommon in the prairies and grasslands of the south and eastern portions of the province.
Intersting Notes: Lynx have very large paws which are well developed for foraging in
snow. The paw, which is sometimes 10cm in diameter, has fur which grows between its toes and
acts like a snowshoe. Showshoe hares make up about 75% of the Canada Lynx's diet and numerous
studies have been done doucumenting fluctations in populations of both Canada Lynx and the
Snowshoe hare. Other prey includes gouse and small rodents.
(Odocoileus hemionus) Family: Cervidae Description: Like most members of the deer family, the Mule deer is relatively large. Males, or bucks, are considerably larger than females, or does. Males are between 150 and 190cm long, 90 to 110cm at the shoulder and weigh 90 to 130kg. Mature males also sport a pair of branching antlers which are grown and shed annually. The smaller female is about 145 to 175cm long and weigh up to 80kg. Mule deer have large ears, a distinguishing characteristic that gives them their name -- its ears were compared to that of a mule's by explorers Lewis and Clark. The mule deer also has a white tail with a black tip which it holds either horizontal or down when it is alarmed and moving. Distribution: The Mule deer is common throughout most of Alberta south of about 57°N latitude.
Intersting Notes: Mule deer have a unique way of getting around. They can bounce away
by pushing off and landing on all four legs at once and when frightened can jump 2m high and
a distance of 6m. They can be found in a variety of habitats including coniferous forests,
aspen parklands, meadows, and wooded areas. They eat a variety of vegitation including grasses,
forbs, leaves and twigs.
(Odocoileus virginianus) Family: Cervidae Description: A White-tail buck is about 160 to 210cm long, 90 to 105cm high at the shoulder and may weigh as much as 135kg. Females are smaller measuring 150 to 195cm long and weigh up to 80kg. In summer the upper body is redish brown and greyish brown in winter. The undersides of the belly and tail, and insides of the legs are white. There is no black tip to the tail as seen in the Mule deer. Antlers on a buck are a single beam with multiple tines branching off of it. Distribution: The White-tailed deer is common to most areas in the southern half of Alberta.
Intersting Notes: Like the Mule deer, White-tailed deer are capable of great leaps --
reaching 2m high and 8m long -- although they tend run in a smooth flowing gallop. The white-tailed
deer also has a very wide diet and can dine over 1000 different plants depending on availabilty.
They tend to prefer buds, twigs, leaves and fruit from plants such as aspen, chokecherry and many
other shrubs.
(Alces alces) Family: Cervidae Description: The Moose is the largest member of the deer family. Bulls may weigh up to 500kg, measure 1.9m at the shoulder and 3.1m long. The rack of antlers is quite large often measuring 120 to 150cm, sometimes as much as 190cm, across wieghing 25 to 35 kg. The main beam broadens into a wide shovel-like "palm" with numerous spikes fringing it. Males also have a large flap of skin called a dewlap which hang from their throat. The dewlap may be as much as 25cm long or more, but seems to serve no known purpose. Cows are smaller measuring 230 to 270cm long and weigh in at 270 to 435kg. Colour varies from grayish-brown to nearly black. Distribution: Moose are found thoughout the Rocky Mountains and Foothills, and in the northern half of Alberta in forested regions of the province.
Intersting Notes: The moose gets its name from the Algonquin Indian
name for the animal - mongswa - meaning "eater of twigs". This huge
deer also feeds on grasses, aquatic plants, lillies and other pond vegitation
in shallow lakes and marshes. Bulls grow an enormous set of antlers each year
which are shed around December or January. The antlers become more masive each
year as the bull matures reaching their maximum size when the bull has reached
the peak of sexual maturity at around seven to ten years of age. Bulls fight
vigorously during the rut, repeated crashing into each other often wounding one
another. A bull may lose up to 20 percent of his body wieght during mating season.
