Evolution and systematics

Procyonids evolved in the tropical environments of South and Central America. Their morphology and habits reveal numerous adaptations for warm climates including naked soles, long digits, diet relying heavily on fruits and berries, and tree climbing skills. Several aspects of their phylogeny (origin) remain unresolved. First, the position of the red panda, Ailurus fulgens, with the Procyonidae (but the giant panda Ailuropoda melanoleuca in the Ursidae) is not universally accepted. In the past, the red panda has been considered under a separate family Ailuridae with the giant panda. Second, the number of species of raccoons (genus Procyon) seems to vary as many previously recognized island species such as Bahaman raccoon (Procyon maynardi), Guadeloupe raccoon (Procyon minor), and the extinct Barbados raccoon (Procyon gloveralleni) have recently been reconsidered variants of the northern raccoon (Procyon lotor). Similarly, five species of olingos (genus Bassaricyon) are currently recognized, but are probably variants (subspecies) of the same species.

Physical characteristics

Procyonidae have a rounded head and ears, short snouts (genus Potos) or long snouts (generas Nasua and Procyon), most have long banded tails except kinkajous (Potos flavus), which have unbanded tails. Pelage varies from pale brown in Bassariscus to dark red in Ailurus, and is variable from yellowish to silver, brown, or even black in some color morphs of Procyon lotor. Facial markings often occur, and are most pronounced in raccoons and red pandas, yet absent in kinkajous. Limbs have five digits, with short, recurved claws. Mass ranges from 2 lbs (1 kg) in Bassariscus to close to 40 lbs (18 kg) in Procyon lotor. Males are slightly larger than females, and have a baculum (penis).

Distribution

Procyonids (except the red panda) occur throughout Central American and the northern half of South America, but the northern raccoon occurs in North America, and now in Germany following introductions. Red pandas occur in the

temperate forests of the Himalayas from Nepal through to provinces of Sichuan and Yunnan in China.

Habitat

Procyonidae are extremely adaptable and occur in all habitats except possibly desertic habitats. Most species probably occur in tropical forests except for the northern raccoon that inhabits farmland, mixed forests and urban areas throughout the United States and Canada. Red pandas inhabit bamboo forests of Asia.

Behavior

With the exception of the coatis, the procyonids are nocturnal species. All species are capable climbers. Some species

such as Bassariscus are solitary, others such as Procyon have variable degrees of sociality, and Nasua is highly gregarious. Solitary species such as Bassariscus or Nasua do not defend territories, but home ranges typically overlap more inter-sexually than intra-sexually. Only red pandas are truly territorial. Some species such as Potos flavus and Ailurus fulgens scent mark.

Feeding ecology and diet

Procyonidae are omnivorous. Some specialization occurs from the ring-tailed cats (mostly carnivores) to kinkajous (frugivore) or red pandas (mostly herbivore), but all species consume plant or animal matter, depending on season or availability.

Reproductive biology

Most species are promiscuous and breed in the spring or throughout the year in southern latitudes. Females bear young once a year after a gestation period of 60–118 days. Males do not provide care for the young.

Conservation status

Twelve species plus one subspecies are listed on the IUCN Red List of Threatened Species. However, listing of two raccoons as Endangered (Procyon minor, Procyon maynardi) and one as Extinct (Procyon gloveralleni) may be invalid as they are forms of the northern raccoon. Among extant species, five are Endangered (Ailurus fulgens, Procyon pygmaeus, Procyon insularis, Bassaricyon lasius, and Bassaricyon pauli), three are listed as Near Threatened (Bassaricyon beddardi, Bassaricyon gabbii, and Bassariscus sumichrasti), and one species as Data Deficient (Nasuella olivacea). The red panda is currently endangered because

of deforestation, killing for its pelt, illegal trade of live animals, and predation by domestic dogs. Estimates suggest that less than 2,500 animals remain. One species of raccoon,

the Cozumel Island raccoon (Procyon pygmaeus) is threatened by urbanization and persecution as pests by orchard owners.

Significance to humans

Procyonids are hunted for their meat and fur, or killed as pests. The northern raccoon has the greatest importance to humans, either as a furbearer, for meat, as a carrier of rabies, or as a pest. Other procyonids such as coatis or kinkajous may also be harvested for their meat or fur, although none to the extent of the northern raccoon.

Northern raccoon

Procyon lotor

subfamily

Procyoninae

taxonomy

Ursus lotor (Linnaeus, 1758), Americae maritimis (Pennsylvania).

other common names

English: Raccoon, coon; French: Raton laveur; German: Waschbär; Spanish: Mapache.

physical characteristics

Body length 18–25 in (50–65 cm), tail 8–12 in (20–30 cm), mass 10–35 lb (4–16 kg). Large rounded head, round ears, black mask across face, long digits and naked feet, long, thick fur, and long tail with numerous concentric dark bands.

distribution

Southern Panama north to the fringe of the boreal forests in Canada. Introduced into Russia and Germany.

habitat

Raccoons thrive in a variety of habitats including forests to mixed forests, prairies, and urban areas.

behavior

Nocturnal, raccoons spend the day sheltered in abandoned houses, barns, culverts, hollow trees, brush piles, or dens of other animals. Home ranges vary according to food abundance, and range from 12 to 6,000 acres (0.5–25 km2). Densities range

from one to 600 individuals per mi2 (0.5–300 per km2), and highest densities occur in urban areas. In northern environments, raccoons accumulate large amounts of fat during late summer and autumn in preparation for an extended period of sleep (up to six months) during winter. Longevity up to 17 years in captivity, but rarely reaches five years in the wild. Main predators are coyotes, bobcats, and alligators.

feeding ecology and diet

Raccoons are opportunistic and consume whatever foods they encounter. Most often, diet consists of fruits, berries, cereal grains, hard mast, crayfish, frogs, and bird eggs. Although historically believed to wash their food before eating, this habit is a myth and simply the result of raccoons often searching for and handling aquatic food with their dexterous forepaws.

reproductive biology

Promiscuous. Mating in February or March. Gestation 63 days, litter size is one to seven. Males do not provide care for the young.

conservation status

Not threatened.

significance to humans

The raccoon is important to humans for meat, fur, as a pest and as a carrier of rabies. The meat is consumed mostly in southern United States and Central America. The raccoon is also an important furbearer across the United States and Canada. Raccoons are sometimes killed as pests, especially for damage caused to crops (corn), for consuming and spreading garbage in urban areas, or for perceived threats to domestic animals (chicken) or wild game birds, especially ducks. In the eastern United States, the raccoon is of significant concern as a carrier of rabies. The ability of raccoons to thrive in the presence of humans is a major factor leading to its importance as a pest: currently, the highest densities of raccoons anywhere are found in large cities such as Chicago (USA), Cincinnati (USA), and Toronto (Canada).

subfamily

Potosinae

taxonomy

Lemur flavus (Schreber, 1774), Surinam.

physical characteristics

Body length 16–30 in (40–75 cm), tail 16–24 in (40–60 cm), mass 3–10 lb (1.4–4.6 kg). Tawny olive pelage with large rounded head and ears, short snout, prehensile tail, and large protruding eyes.

distribution

Southeast Mexico through Central America into Brazil.

habitat

Southern tropical forests.

behavior

Solitary and arboreal, kinkajous rest in hollow trees during the day. They scent mark, possibly to communicate or advertise sexual status. Kinkajous are not territorial, and animals may aggregate near good food sources. Density may reach 30–75/mi2 (12–30/km2). Longevity may reach 23 years in captivity.

feeding ecology and diet

Fruits, honey, insects, bird eggs and nestlings, and rarely small mammals.

reproductive biology

Promiscuous. Breeding throughout the year. Gestation 112–118 days, litter size typically one, but rarely two.

conservation status

Not threatened.

significance to humans

May be eaten in some localities.

Procyoninae

taxonomy

Viverra narica (Linnaeus, 1766), America (Vera Cruz).

other common names

English: Coatimundi; French: Coati à nez blanc; German: Nasenbär; Spanish: Tejón.

physical characteristics
