For generations, raccoons have been stereotyped as the cunning thief or trickster character in literature because of the black marks that fall across their eyes. But in addition to giving them the appearance of cute outlaws, their well-known black masks also provide them the ability to see perfectly. Dark to the black stickers that athletes wear beneath their eyes, the black fur works by absorbing light that would otherwise bounce into the athlete's eyes and impair vision. Less peripheral light during the night, when raccoons are most active, makes it simpler for them to detect contrast in the objects of their focus, which is crucial for seeing in the dark.

Can humans get raccoon roundworm? Raccoons are the primary host of Baylisascaris procyonis, a roundworm that can be harmful to people. Roundworm eggs are passed in the feces of infected raccoons, and people become infected by ingesting eggs. Anyone who is exposed to environments where raccoons frequent is potentially at risk.

Do raccoons die from rabies? Raccoons—along with foxes (red and gray), skunks, and bats—are considered a primary carrier of the rabies virus in the United States. While any warm-blooded animal can carry rabies, these are the ones we call “rabies vector species.”

Do raccoons come out in the winter time? During cold spells they will curl up in a ball or lay on their backs, covering their eyes with their front paws and sleeping for days at a time. But if the cold weather snaps, it is not unusual for the nocturnal raccoons to come out in search of food.

Do raccoons come out during the day? While it is true that a rabid raccoon will exhibit a variety of unusual behaviors, activity during daytime is most definitely not a guaranteed indicator of rabies. You see, although raccoons are primarily nocturnal, they do often get some stuff done during the day.

Raccoons are one of the few extinct species that have profited from the spread of humans. Despite the devastation of much of the creatures' natural habitat over the past few decades, populations in North America have skyrocketed. Raccoons are versatile enough to thrive successfully in suburban, urban, and rural settings. Raccoons scavenge for trash and pet food in residential areas while eating birds, insects, fruits, nuts, and seeds in woodlands. Some raccoons forage in areas where people live and then spend the day sleeping in the woods. Others live in buildings, both occupied and unoccupied.

In the early 20th century, raccoons were poised to become the go-to model for animal experiments. They were some of the most curious and intelligent animals available, scientists believed, so that meant they were an obvious choice for comparative psychology studies. Though raccoons were the subject of several psychology experiments at the turn of the century, they didn't stick around in labs for long. Unlike rats, they were hard to breed and maintain in large numbers. They also had the pesky tendencies to chew through their cages, pickpocket researchers, and hide out in air vents. Despite one researcher's plan to breed a tamer strain of raccoon, the creature's future in the lab never took off.
