Mammals are the smallest groups of animals with only about 5,000 species of mammals. They range in size from the huge blue whale which can reach a size of up to 80 feet long to tiny rodents. Most of the mammals that we commonly see live on the ground but they also live in the trees and in the water. They also live in many different environments including underground, on the land, in caves, in the ocean and some can even fly (bats).
Most of the mammals that we commonly see are mammals that have been domesticated like cows, horses, dogs and cats however there are some wild mammals that live near humans. Some of the mammals that can possibly be seen in city parks and neighborhoods are squirrels, rabbits, rodents, raccoons, opossums and armadillos.
Seeing wild mammals in their natural environment typically requires a little more effort. Most truly wild mammals live in heavily wooded area with thick underbrush and they are very fearful of humans. To see these mammals we need to get off the beaten paths, move very quietly and have a lot of patience but when I have seen these mammals, the reward was worth the effort.
