Common Raccoon

<em>Procyon lotor</em>, the common raccoon, is a medium-sized mammal in the family Procyonidae, order Carnivora. Native to North America, it has been introduced across parts of Europe and Asia, making it one of the most geographically widespread non-domestic mammals in temperate regions. Raccoons typically inhabit deciduous and mixed forests, wetlands, urban parks, and suburban neighborhoods, demonstrating remarkable adaptability to human-modified landscapes. Their geographic range spans from Canada south through the continental United States into Panama, with introduced populations established in Germany, France, Japan, and parts of Russia. The species is listed as Least Concern on the IUCN Red List, with populations stable or increasing across much of its range. Raccoons are omnivorous, typically consuming invertebrates, small vertebrates, fish, fruits, nuts, and human refuse depending on seasonal availability. Their distinctive black facial mask and ringed tail make them immediately recognizable. They are primarily nocturnal and are known for their dexterous forepaws, which they use to manipulate food and open containers. Raccoons do not hibernate in most of their range but may enter extended periods of torpor during harsh winters.
