Raccoons have a yearly life cycle with breeding in late winter and early spring, growth in summer and fall, and winter denning in colder climates, although they do not hibernate. Dens are found in natural structures and human-made buildings, with males typically denning alone and families staying together.

The species is native to North and Central America, with its range expanding northward in Canada and introduced populations in Europe. Raccoons are omnivores with a varied diet that shifts seasonally. They eat animal matter like invertebrates and insects in spring, and more plant material, such as fruits and nuts, in summer. Corn and other crops dominate their fall diet, which is crucial for fat accumulation to sustain them through winter. Raccoons can be problematic for humans, raiding garbage and preying on farm animals and crops.

Summarize the the following text:

Description. The common raccoon (Procyon lotor) is probably best known for its mischievous-looking black face mask. Raccoons are usually a grizzled grey in colour with a tail marked by five to 10 alternating black and brown rings. Body coloration can vary from albino, (white) to melanistic (black) or brown. An annual moult, or shedding, of the fur begins in the spring and lasts about three months.The head is broad with a pointed snout and short rounded ears measuring 4 to 6 cm. The eyes are black. Total body and tail length for adults averages 80 cm; males are generally 25 percent larger than females. Raccoons in northern latitudes tend to be heavier (6 to 8 kg) than their southern counterparts (4 kg). However, fall weights for adults have reached 28 kg in some areas. Habitat and Habits. Raccoons are able to live in a wide range of habitats. The only apparent requirements are a source of water, food, and a protected area for denning. The best habitats are hardwood swamps, floodplain forests, fresh- and saltwater marshes, and farmland, both cultivated and abandoned. On the prairies, raccoons are most abundant in woodlot and wetland areas. This highly adaptable animal is also very common in many cities of North America. Movements and home ranges of raccoons vary greatly depending on habitat, population density, and food supply. The home range is the area used by an animal for food, water, and shelter in its normal, day-to-day movements. In rural agricultural areas of eastern North America, home ranges between 1 and 4 km2 are common, whereas in prairie habitat, raccoons have used areas as large as 50 km2. At the other extreme, the area used by urban raccoons has been documented at less than 0.1 km2. Generally, home ranges of individual raccoons overlap, and there is little evidence of territoriality, especially in urban areas. As with home ranges, raccoon densities vary significantly depending on the type of habitat. Estimates of five to 10 raccoons per square kilometre are common in rural agricultural areas. In urban areas, exceptional numbers of raccoons, as high as 100 per square kilometre, have been recorded. However, densities as low as one per square kilometre may occur in prairie habitat.In the northern United States and southern Canada, the annual life cycle of raccoons consists of a breeding period during late winter and early spring, a growth and fattening period during the summer and fall, and a winter denning period. In more southern latitudes, winter denning occurs only during periods of poor weather. Winter denning allows the raccoon to conserve energy in the form of fat reserves when food is not available. This is not hibernation, but a period of inactivity. The body temperature does not drop, and the animal's activity appears to be governed by the air temperature. Preferred denning sites include hollow trees, stumps, logs, caves, vacant groundhog or fox burrows, and buildings such as barns. In city areas, denning sites include residential chimneys, sewers, garages, attics, trees, and culverts. Adult males usually den alone, but the family unit often dens together during the first winter. Communal dens containing as many as 23 raccoons have been reported; however, four to five is more common. Although usually one den is used during the winter, several different dens provide sanctuary during other seasons. Range. Six species of raccoons occur in North, Central, and South America as well as on some of the Caribbean Islands. However, Procyon lotor is found only in southern Canada, portions of the United States, and Central America. The species inhabits all provinces of Canada except Newfoundland and Labrador and is gradually expanding its range northward as land is cleared for agricultural purposes. During the 1930s the raccoon was successfully introduced into Germany and the Soviet Union. Today, its range has expanded to include Luxembourg, West Germany, the Netherlands, and France. Feeding. Raccoons are omnivorous and will consume practically any food item, plant or animal. They prefer corn, crayfish, fruits, and nuts, but there is a seasonal shift in diet depending on availability of food items. During the spring, animal matter, including invertebrates, or small animals without backbones, and insects, makes up the major portion of the diet. While they prefer crayfish, raccoons also consume muskrats, squirrels, rabbits, waterfowl eggs, and freshwater clams. In the summer, plant material, including fruits and nuts, becomes more important. Wild cherries, gooseberries, elderberries, wild grapes, strawberries, and garden items such as potatoes and sweet corn are relished. They also eat frogs, small fish, turtles, beetle grubs, grasshoppers, earthworms, crickets, and snails during the summer. Corn is the mainstay of the fall diet in most areas where it is available; however, acorns, beechnuts, hazelnuts, and grapes are also consumed. Raccoons raid the nests of insects, including hornets, bumblebees, termites, and ants, mainly for the larvae, or immature stage. The raccoon's thick fall and winter coat protects it from the stings of irate adult hornets or bees. The fall diet is extremely important for raccoons in northern latitudes because they must accumulate sufficient fat reserves to sustain them during winter denning. The raccoon builds up fat over its entire body, even around the tail bone. It may be 2.5 cm thick on the back. In fact, by late fall about half of the animal's total body weight may be fat. In northern areas the raccoon lives on its stored body fat during the winter, but farther south where nuts and corn are plentiful it continues to hunt for food year-round. In suburban areas, raccoons often raid garbage bins or hunt for earthworms, beetles, and grubs on residential lawns. Raccoons can also be a menace to farmers because they may eat domestic fowl and eggs.

The common raccoon (Procyon lotor) is a grey-colored animal with a distinctive black mask and ringed tail, varying in size and weight depending on the region. It undergoes an annual fur molt and has a broad head, pointed snout, and short ears. Raccoons are highly adaptable, thriving in various habitats provided there's water, food, and denning areas. Preferred environments include forests, marshes, farmlands, and urban areas. Their home ranges can vary widely, with rural individuals ranging between 1 and 4 km², while urban raccoons may occupy areas less than 0.1 km². Population densities fluctuate with habitat types, with urban areas seeing higher concentrations than rural or prairie regions.
