Ontario: Nature and Prosperity in Harmony

Ontario, Canada’s second-largest province after Quebec, offers a fascinating interplay between its diverse wildlife and robust economic prowess, all within its vast territory. The province’s climate and geography determine its unique animal inhabitants, while its status as the most populous province, home to over a third of Canada’s population, showcases its cultural vibrancy. Ontario’s wealth, driven by abundant natural resources and a thriving industrial economy, makes it Canada’s economic powerhouse and a significant player in national politics. The province is geographically divided into Northern Ontario, known for its expansive forests and crucial hydroelectric projects, and Southern Ontario, characterized by a picturesque landscape filled with lakes and gentle relief land, providing a remarkable blend of natural beauty and economic vitality.

White-tailed Deer

The white-tailed deer is the first member of our list of animals in Ontario. It is also known as Virginia deer, is medium-sized and native to North America, Central America, and South America. White-tailed deer got its name due to the white hairs under the tail and rump. White-tailed deer have different sizes. Its body is found to be more significant in cold climates and agricultural soil but more petite in deserts and tropics.

It has a reddish-brown to grayish-brown body and large ears. They love to live in open areas and forests. During summer, white-tailed deer are found in forest areas where the food is present more, and in winter, they live in yards where they get proper nutrition and protection from cold winds. They reproduce quickly and are capable of doubling their number in a year.

White-tailed deer are herbivores or vegetarians as they feed on grasses and herbs, leafy material from plants and wood. As in the winter season, there is a shortage of food; they change their diet to buds and twigs.

American black bears are medium-sized in North America, including some parts of Mexico. White markings are found on their chest sometimes. American black bear consists of single species, and They differ in color. Black bears are native to western North America.

The black bear is more enormous and ranges from five to six feet long. Male black bears weigh 70% heavier than female black bears and have small heads further supported by solid necks. American black bears are classified as carnivores but have an omnivorous diet.

They mostly live in forests and hence need a forest habitat to survive. Their body is adapted so that they can easily climb trees or even dig for food. These black bears can even travel a long distance of up to around 200km and can even come back to the place from where they started.

Winter time is rest or hibernation time for black bears, so they spend most of their time in the den. These dens have a lot of variety, as hollow in a log, open under tree roots, or even a digger placed in the ground, which they cover with leaves later on.

They start to mate or reproduce in early summer, June- July. Most diet comes from plant material.

It is among the most found among the other nineteen species of bats in Canada. They weigh only seven to fourteen grams. Little brown bats are closely linked with humans as they make residence on buildings. Little brown bats do not move out from Canada but can carry up to 1000 km from summer start to winter end. They are true hibernators, and so hibernate in winter. They use tree cavities or building tops to lay eggs.

Little brown bats feed on different varieties of insects. They are so sharp and active as they can catch up to 1000 insects in an hour. They do feed mainly on insects having an aquatic larval start. The myth is that bats are blind, but little brown bats have powerful vision.

These bats have a long life compared to other small mammals and can live up to 10 years. They use echo to fly and find food. These also play an essential role as a predator of insects those fly at night. As we all know, bats are nocturnal and can be found at the top of budlings or trees hanging downwards—a notable entry for this list of animals in Ontario.

It cannot tolerate high temperatures, which is also why it is found in southern Ontario.

They make nests or live in abandoned buildings. It also lives in cavities and trees. It lives in its central nest for a year, then to hunting rodents in fields, meadows, orchards, grasslands, etc. Due to urbanization, these owls are getting endangered. Their hearing sense is sharp, so they get their food by hunting small animals on land. They have a high metabolic rate and consume a lot of rodents, depending on their size.

They save food at roosting sites so they can feed on them when food is scarce. This is also why these owls are the most economically valuable animals. Another worthy mention in our list of animals in Ontario.

Say hello to our next entry for this list of animals in Ontario. The loggerhead shrike is a robin-sized bird that hunts small insects, animals, and birds. Two of the 11 subspecies of long-head shrike are found in Canada. Subspecies have a similar appearance:: the wings are black and white, the back is greyish, the chest and belly area is white, and the tail is black with white stripes on the sides. These birds have a heavy and extended head compared to the entire-body, so their name comes out to be loggerhead shrike.

Trumpeter Swan

Trumpeter swans are enormous, as the average male weighs 26 pounds. They need open water to run across. When they are three to four years old, they form pair-bonding; this pair stays together throughout the year, even while moving in migratory populations. It is found that trumpeter swan mates for life and those who lost their partner do not mate again. Trumpeter swan takes a different approach towards incubation as they warm their eggs by covering them under their webbed feet. Its scientific name is Cygnus buccinator. It is the heaviest bird native to North America.

These birds primarily breed in pristine wetlands, slow rivers, lakes, and shallow ponds. Their preference is for wide, undisturbed areas with unpolluted water, abundant food accessibility, and minimal human disturbance. During migration, they form V-shaped flocks, and while swimming in water, they feed or may even dive for submerged food.

The central part of their diet includes aquatic plants.

Trumpeter swans will eat both leaves and stems of submerged and visible vegetation. In winter, they are also found eating grasses and grains. They prepare for the spring breeding season, so their feeding activity and weight change. Male trumpeter swans are called cobs; juvenile are called cygnets, and female swans are called pens. Male trumpeter swan weighs 9 to 14kg and is generally more prominent than 9-12kg but has no color difference.

It is the most common and abundant bat in North America and is among the 18 species found in Canada. They have brown fur on them, measurements 9 to 14 centimeters in length, weighing 11 to 25 grams. The big brown bat can be found in Southern Canada, Colombia, and Venezuela.

This species can be found in different habitats but mainly in deciduous forests. This species is very well adapted to human beings, and it is commonly found in large and small cities. In the winter, it hibernates in churches, houses, mines, etc., while some big brown cats hibernate in tree cavities and rock crevices.

It is not at risk of extinction, so its conservation is not much concern or focus. But these species face severe clashes with humans as they live in budlings or, we can say, in artificial structures. The big brown bat is insectivorous as they eat many insects, including stone flies, mayflies, true bugs, beetles, scorpion flies, cockroaches, etc.

They are widely spread over southern parts of Ontario. Their antibodies are used to cure rabies as these species of bats provide immunity, so farmers in Ontario use bat boxes to attract them to their lands. A human being’s baby weighs about 6 percent of their mother’s weight, but surprisingly, a newborn little brown bat weighs 25 percent of their mother’s weight. They are prone to white-nose syndrome.
