If you give raccoons a problem, they'll typically figure out how to solve it as long as there's food involved. They have repeatedly demonstrated this in labs in addition to yards and campsites. Early in the 20th century, ethologist H.B. Davis presented 12 raccoons with a set of locks to pick. They had to negotiate hooks, bolts, buttons, latches, and levers to get to the rewards inside the boxes; some of the boxes had multiple locks. The raccoons eventually managed to bypass 11 of the 13 defenses.
Are the raccoons dangerous? Raccoons can carry several dangerous diseases including rabies. While incidents of rabid raccoons attacking humans are rare, it's not something you want to risk.Raccoons carry two other diseases, roundworm and leptospirosis, that can also be transmitted to humans and pets.
In order to stock fur farms, the first raccoons were sent to Europe in the 1920s. Many raccoons escaped and started a new population in the wild thanks to an unintentional bombing and some bored farmers looking to spice up the local wildlife. Raccoons are now regarded as an invasive species in Europe.
The animals were even sent to Japan. Their journey there began more virtuously: Rascal the Raccoon, the wholesome star of the anime animation, was a childhood idol among Japanese kids in the 1970s. Children clamored for their own pet raccoons, and at one time Japan was importing almost 1500 of them each month. When these pets became too large for families to properly care for them, many of them naturally ended up back in the wild.
Can raccoons climb up and down vinyl siding? Raccoons are excellent climbers, so it's fairly difficult to keep them from climbing on the roof. They can ascend the corners of most houses, and easily climb up and down downspouts. Raccoons can tear open eaves, and even shingled roof, so beware of the damage they are capable of.
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.
More recently, scientists gave the Aesop's Fable test to some raccoons. Researchers have adopted the well-known parable of a crow throwing stones into a pitcher to cause the water level to rise as a benchmark for animal intelligence. Raccoons were put in a space with a water cylinder, marshmallows floating on top, and stones strewn about it. They had to raise the water level first by dumping the stones before they could get to the sweet treats. Two of the eight raccoons imitated the action after being shown how to do it, but a third approached the issue differently and knocked the entire structure over.
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.
