Interesting facts:
Porcupine's babies are called pups.
Porcupines have an odor that gets stronger when they are agitated.
Porcupines are the only North American animal with antibiotics in their skin.
Porcupines have quills that are easily detachable and are toxic.
Diet and predators
The north American porcupine is a herbivore. It’s main food source is different types of wood, but it eats berries and springtime flower buds. It has large front teeth that help it eat wood. A porcupine is usually preyed on by wolves, but they use their quills and odor to ward off prey.
Range and habitat
Porcupines live in the forests of North America. They can also live in grasslands and deserts of Europe and Asia. There are many predators that share the same habitat with porcupines, so they use their quills as defense.
Reproduction
A porcupine reproduces sexually, and has one pup at a time. The mating season of a porcupine is once a year during the months of October and November. When the pup is born for six weeks the mother stays close to it. After a month the mother will start to leave the pup alone until winter when she leaves the pup forever.

Origin - The Maine Coon is a natural breed, however currently the actual origin of the Main Coon is still underway. The "myth" of the Maine Coon coming about from the mating of raccoon and domestic cat is amongst the most popular. Although this is genetically and scientifically impossible to achieve, it first came about to be believed due to its unique brown raccoon-like markings and big bushy tail. "Maine Shags" were the name given to those that had markings any other color besides the brown coat. Theory of Maine Coons coming about from Viking's bringing these animals over into North America has been one of many popular theories. However, the most common theory is that of Marie Antoinette. Many believe when she tried to escape to North America, but did not succeed, she had left her long-haired cat on board, which then came to North America and bred
The tar pits were surrounded by grasslands, shrubby areas and pine forests. Sabertooth cats fed off of herbivores so they often times lived in areas like this because many of the plant-eating animals sabertooth cats relied on lived in these areas. Smilodons also preferred to live in closed habitats so that it was easy to ambush it’s prey while hiding in bushes. Fossils show some evidence that Sabertooths were social, perhaps even living in groups to care for one another. Fossil records also suggest that they lived in icy lands, as they lived during the end of the Dinosaurs and during the Ice Age.
The population of the whooping cranes most definitely gets affected from precipitation, because the population gets affected negatively with high precipitation levels present, while positively with low precipitation levels. The population of the whooping cranes gets affected this way because if there were high precipitation levels for a year, the hatching success rate drastically decreases from the precipitation, who damages the eggs laid by the cranes. By either breaking the eggs, making the cranes not be present to incubate their eggs, or actually destroying the birds’ nests. Also, the high precipitation levels may even cause a few fatalities, which is a very serious problem involving this particular endangered species. While with low precipitation
They use their large wings to fly around and spot carcasses below. “There are about 435 California condors in the world today, in which 237 are living in the southwestern part of California. They live in California, Arizona, and Baja California, Mexico.” (Defenders of Wildlife, 2013) They’re as north as Big Sur to Ventura County and as east as the Sierra Nevada Mountain range, with other populations inhabiting the Grand Canyon in Arizona.
During the warm season (summer), piping plovers usually lives and nest on the sandy beaches, shores of the Great Lakes, major rivers, or the prairies. They usually breed on dry sandy beaches and in the winter, they settle along the shores of southeastern United States.
Duck Hunting has been around since the 17th century and waterfowlers have been passing down the great tradition of waterfowl. Waterfowl or also known as duck hunting has been a growing sport and more and more people are starting to duck hunt around America.
If puffins are disturbed by humans they will leave their nests and will not come back. This has led to the extinction of puffin colonies in parts of the European coastline.
physical characteristics of the platypus are quite interesting. It is the size of a normal cat,
Ocelots are the miniature leopards of the jungle. The hundreds of thousands that populate the southern region of North America and South America are domesticated and wild. These active travelers have moved more into Central America and barely any remain in North America. Their blotched black and tan spots resemble those of a leopards which is another reason why people want to buy them. Even though there are large numbers of them, they are not well known.
peregrines range across the treeless regions of Alaska and Canada. They are also found in
Modern wildlife management technicians use humane cages to capture destructive pests and easily remove them to greener pastures. A 32-42 inch rust-resistant steel cage will safely trap and hold a groundhog or woodchuck until it is relocated.
What it looks like: Siberian tiger is the largest and most rare of all members of the cat family. This cat is 8-10 feet long, excluding their 25-38 inch rattling tail. This species of tiger weighs 400-700 pounds. Like all members of the tiger family, males are significantly larger than females.
...s. They have similar behavioural characteristics and habitats as tigers (they roam around rivers). Panthera pardus (leopards) do not however live in Latin America, this species can only be found in parts of Africa (e.g.:sub-Saharan part) , tropical, South and West Asia or Siberia . Both jaguars and leopards have rosette spots whereas cheetahs have round black spots. They are also slender looking and inhabit most of Africa and parts of the Middle East. Cheetahs are also by far the fastest cats of the Felidae family; they can run as fast as 120 km/h ( up to 75 mph) .Tigers are the largest of all cat species with a total body length of up to 3.3 metres. Its most recognisable feature is a pattern of dark vertical stripes on an orange fur with a lighter underside.They once ranged across Asia, from Turkey to Russia but are now in pocket areas in Asia, Malaysia and Russia.
They Hyena mostly live in Africa, south of the Sahara, but except in the Congo Basin. Also large numbers of Hyenas live in Ethiopia, British Somalialand, and Ngrongoro Crater. Their habitat is usually a flat grassland. It is mostly dry and sometimes rocky area. There are few trees or plants. Mostly there are shrubs. There are also some mountains in the region.
