The raccoon (Procyon lotor) is a highly resourceful mammal recognized by its distinctive black facial mask and ringed tail. This species is native to North America and is noted for its exceptional dexterity, utilizing its front paws to manipulate objects. The raccoon’s most defining characteristic is its remarkable ability to adapt, which has allowed it to successfully colonize a vast range of environments, from dense wilderness to highly developed urban centers. This success is directly tied to its flexible behaviors and omnivorous diet, enabling it to exploit resources across dramatically different landscapes.
Geographic Distribution of Raccoons
The native range of the raccoon spans across North and Central America, extending from southern Canada through most of the United States and into Mexico. Historically, the species was less common in the high elevations of the Rocky Mountains and the arid regions of the Southwest. However, agricultural irrigation and urbanization have allowed the raccoon to expand its range into these previously unsuitable areas, such as Utah and Nevada, over the past century. The total estimated geographic range in North America increased significantly from the 1920s to the 1980s, in part due to conservation efforts. The species is now found in nearly all of the lower 48 states and has been introduced to parts of Europe and Japan where it is considered an invasive species.
Natural Micro-Habitats
In non-urban settings, raccoons demonstrate a strong preference for habitats near water sources. They are frequently found in riparian zones, which are areas along the banks of rivers, streams, ponds, and marshes. These moist environments provide a reliable source of water and a diverse food supply, including crayfish, frogs, and other aquatic invertebrates that raccoons actively forage for.
For daytime rest and shelter, raccoons establish multiple den sites and rotate between them to avoid disturbance. In forested areas, their preferred den locations are natural cavities, such as hollow trees and logs, which offer protection from predators and weather. They will also utilize rock crevices, dense brush piles, and abandoned burrows dug by other animals.
Urban and Suburban Adaptation
Raccoons thrive in human-dominated areas due to the abundance of shelter and readily available food, often reaching higher population densities in cities than in the wild. They repurpose human-made structures as den sites, seeking out warm, dry, and secure locations that mimic their natural tree hollows. Common residential den locations include attics, where they may tear up insulation to create nests, and uncapped chimneys, which provide protected shafts for resting.
The spaces beneath decks, sheds, and porches also serve as frequent den sites, offering quiet, sheltered areas close to the ground. Raccoons may even exploit storm drains and sewers for travel and temporary shelter, using the subterranean network to navigate urban environments. The primary attractants drawing raccoons into these human spaces are anthropogenic food sources, particularly unsecured garbage, outdoor pet food, and bird feeders.
Behavioral Clues for Observation
Raccoons are primarily nocturnal, meaning they conduct most of their activity, particularly foraging, between dusk and dawn. They often exhibit crepuscular behavior, with peak activity occurring during the twilight hours. While an occasional daytime sighting does not necessarily indicate illness, persistent daylight activity may suggest a readily available food source or a disturbed den site.
The presence of raccoons can often be detected through specific physical signs. Their tracks are distinct, featuring five toes on both the front and hind feet, often described as resembling tiny human hands, which can be found in mud or soft soil near foraging areas.
Raccoon scat is often found in communal “latrines,” usually near a den entrance or a vertical structure they climb. Scat can be identified by its blunt ends and varied contents reflecting their omnivorous diet. Noises are also a clue, with chattering, growling, and purring used for communication. Distinct sounds like “thumping” or rustling in an attic or chimney can indicate a den site.
