Pavol Koval Matúš Knobloch The American beaver is one of two living species .The American beaver can reach weights in excess of 30 kg, making it the world's second largest rodent. American beavers are stocky and have a compact body and short legs. The brown bear is among the largest and most powerful of all land carnivores. They can run at a considerable clip despite their large size and are know to reach speeds of up to 56 km/h.Brown bears have a coat of black, brown or tan fur with longer outer hair often of a different color. The American moose is the largest member of the deer family. Moose have a large, heavy body and long legs. They have a long head, flexible upper lip and nose, and large ears. Their fur is dark brown (almost black) and fades during the winter months. The Arctic wolf is a subspecies of the grey wolf .Adult Arctic wolves are between 63 and 78 centimeters in height and reach weights of up to 83 kg. Females tend to be smaller and lighter than males.. Occasionally, Arctic wolves form groups of larger numbers (up to 30 individuals). The black-footed ferret is North America's most endangered mammal. Black-footed ferrets have light yellow-buff fur and a pale underside, a white face, snout and throat, and black feet. They also have a black mask around their eyes. Caribou also known commonly as reindeer, are members of the deer family that inhabit boreal forests and tundra of North America, Siberia, and Europe. There are four subspecies of caribou and each of the subspecies differs slightly in its coat color and size. Coat color of caribou may be dark brown to nearly white depending on season and subspecies. The monarch butterfly has a black body with white spots and bright orange wings with black borders and veins (some white spots are dappled in the black wing areas too). Monarchs are poisonous due to toxins in the milkweed plant (milkweed is a foodsource for the monarch caterpillar) and their bright coloration serves as a warning to potential vertebrate predators. Ruby-throated hummingbirds are tiny birds that grow to lengths of 75mm-90mm and weights between 3.4g-3.8g .Both sexes have metallic green feathers on their back and white feathers on their belly. Males have irridescent ruby colored feathers on the throat. The Tufted Titmouse is a small, gray-plumed songbird, easily recognized for the crest of gray feathers atop its head, its big black eyes, black forehead, and its rust-colored flanks. They are quite common throughout the eastern part of North America, so if you're in that geographical region and want to catch a glimpse of a Tufted Titmouse, it may not be that difficult to find. The nine-banded armadillo is an intriguing creature with bony armor and leathery skin covering its body.. This armadillo species is about the size of a small dog, reaching lengths of 35 to 55 centimeters and wieghts of 2 to 6 kg. The armadillo has a tail that can grow to a length of about 45 centimeters.
