Fox squirrels make up the largest species of tree squirrels. They are mostly found in forests that have either less or no understory vegetation.
A female fox squirrel produces two litters in a year. Baby squirrels are blind and hairless.
Fox squirrels generally take more time than other squirrels to develop completely.
These squirrels also come under the category of tree squirrels and normally reproduce during the summer.
Abert’s squirrels were named after a military officer in America whose name was John James Abert.
Around nine subspecies of Abert’s squirrels have been recognized. These squirrels make use of ponderosa pines for their habitats, food, and shelter.
Red squirrels are also recognized as tree squirrels and are herbivores. They are usually found in coniferous forests.
On average, a female Red squirrel produces two litters in a year. One between February to March and the second between May to June. One litter contains three baby squirrels known as kits. There has been a drop in Red squirrels population in the past few years.
Pine squirrels are tree squirrels that usually comprise three subspecies: American red squirrel, Douglas squirrel, Southwestern red squirrel.
These squirrels are granivores and have seeds, nuts, and small insects for food.
Rock squirrels are found on the grounds of Colorado and are herbivores. Typically, a female rock squirrel produces two litters per year, and each litter ranges from three to nine baby squirrels.
These squirrels fall prey to raptors, snakes, and some mammals as well.
Colorado Squirrel Characteristics
Here are some characteristics of colorado squirrels.
Fox squirrels share some resemblance with American red squirrels even though their colors are different. Mostly, fox squirrels are brown with either a grayish or a yellowish shade on the upper part of their body.
In eastern areas, they are darker in color, with white bands around their face and tails. While in southern regions, they are usually plain black with no patterns or shades.
Fox squirrels have strong eyesight and a good sense of smell and hearing. In addition, they have whiskers around their eyes, chin, and nose to help them beware of the surroundings.
These squirrels are also called tassel-eared squirrels because of the tassels of hair on their ears.
During the summers, these tufts either become small in size or disappear. Abert’s squirrels have gray hair on the sides, a white stomach, and red on the back.
They are good climbers and can make long jumps from branches.
The red squirrel has fur that changes color from different shades of black and red according to location and season.
They are mostly found in red that helps them in camouflaging with the wood of pine trees. Their bellies are whitish cream, and their fur comes off two times per year.
They have long tails and sharp claws to help them make long leaps from tree to tree while maintaining their balance.
Their tails also keep them comfortable when they are asleep. Their legs are strong, and they can swim too.
American red squirrels have a red coat with a white stomach. They must find an area for themselves that suits them for living to survive. They are not very social and usually stay around their territories.
The Douglas squirrel shares physical resemblance with the American red squirrel. However, their bellies are more of a rusty shade.
Rock squirrels are usually brown with shades of gray. This gray shade morphs into a darker brown on their bellies. Around their eyes, there are rings very light in color.
Their tails are tall with thick fur and have white edges. Their ears are positioned directly above their heads and are pointed at the ends.
Colorado Squirrels Plague
Around two millenniums ago, the Bubonic plague, also called the Black Death, was discovered in Asia. Within five years, 25 million people in Europe died because of this plague.
The Colorado squirrels have been known for carrying this plague since the 1940s. Although several rodents can spread this plague, ground squirrels are the most common transmitters.
It spreads to people very rarely, just in cases where a person has infected lungs by respiratory droplets or when bitten by infected fleas or rodents. Either way, they can be prevented by taking the simplest of precautions. Also, it can be cured by antibiotics as it is caused by bacteria called Yersinia Pestis.
Ground squirrels also get infected by this plague when bitten by infected fleas. Squirrels die because of it. The infected fleas usually find hosts, generally rodents, for the spread of this disease.
Squirrel Plague California
In California, the Bubonic plague is mostly found amongst ground squirrels and chipmunks. It does not infect humans, cats or other animals. They can get infected by it only when they go to wild areas where this plague is spread.
The last case of the Bubonic plague in California was recorded in 2020. Before that, two people tested positive for this plague when they were in a park in 2015. Both were treated and they recovered.
Squirrel Plague Tahoe
The plague found in squirrels, the Bubonic plague, was also detected in Tahoe when a dead squirrel with ten fleas was found at Lake Tahoe promptly resulting in the sites being temporarily closed. This affected the beautiful spots near Lake Tahoe which were pretty famous.
After the burrows of squirrels and other rodents were sprayed with insecticide, Lake Tahoe was opened a week later.
Colorado Squirrel Plague Symptoms
The symptoms of Bubonic plague are shown around two to six days after the person has been infected. It is better to treat this disease as soon as it is diagnosed to prevent any altercations.
- The plague causes lymph nodes to swell greatly and leak puss after being developed.
- A person may suffer from fever, chills, and pain in the abdomen, legs, and arm muscles. Headaches are also one of the common symptoms.
- Patient starts becoming very weak.
