Squirrels are cute and active animals belonging to the Sciuridae family, a diverse group of mammalian rodents. They are characterized by their intelligence and swift movements.
In this article from the teketrek website, we will take more about it.
About Squirrel
With their bushy tails, squirrels are found all over the world. They inhabit most forested and temperate woodland areas globally. Squirrels are an important part of the ecosystem, contributing to tree seeding and plant dispersal. There are over 200 species of squirrels, classified into three categories: tree squirrels, ground squirrels, and flying squirrels.
Squirrel appearance
- It has a slim body that allows it to move quickly in trees.
- Its body is covered with soft, dense fur that protects it from cold and harm.
- The squirrel considers its long tail an important part of its body, as it uses it for balance while jumping and moving in trees.
- It has two large ears that enable it to hear sounds clearly, helping it avoid danger and communicate with other members of the species.
- It has large eyes that enable it to see its surrounding environment well.
Squirrel specifications
- Squirrel sizes vary by species, but the general size ranges from 7 to 100 centimeters.
- Squirrel weights vary by species and region, but they usually range from 15 to 600 grams.
- Squirrel colors vary between gray, brown, white, and black, depending on the species and the region they inhabit.
Squirrel sizes
- Due to numerous species of squirrels, they vary greatly in size.
- The smallest squirrel is the African pygmy squirrel, measuring from 7 to 13 centimeters and weighing only 15 grams.
- The Indian giant squirrel holds the title of the largest known squirrel in the world, reaching a length of approximately one meter and weighing 1.8 kilograms.
- Gray squirrels, typically found in North America, are medium-sized squirrels. They measure from 38 to 50.8 centimeters in length, with tails adding an extra 15 to 25 centimeters. They usually weigh around 0.45 to 0.68 kilograms.
Weird and interesting facts about squirrels
1. Squirrels possess a strong memory that enables them to remember the locations where they bury food, with their memory lasting from several months to several years.
2. Squirrels consume a wide range of foods, including seeds, nuts, fruits, insects, and small birds.
3. Squirrels have padded feet, allowing them to jump remarkably well. Some species can jump distances of up to 20 feet between trees.
4. Squirrels have four teeth in the front of their mouths. Their teeth grow continuously throughout their lives, ensuring that they don’t wear down from gnawing on nuts and other items. To avoid excessive tooth length, they gnaw and polish their teeth by chewing on hard objects like small branches and wood pieces.
5. Squirrels use their tails as a tool, able to hang themselves from trees or enhance balance while jumping.
6. Squirrels rely on caching during seasons, storing food in the fall to consume it in the winter when food is scarce.
7. Squirrels communicate with each other through a variety of sounds, including short warning calls and long calls for inter-individual communication.
8. Their eyes are high on their heads and positioned on each side of the head, allowing them to see a large amount of their surroundings without needing to turn their heads.
9. Squirrels can run at speeds of up to 32 kilometers per hour.
- Gray squirrels come in a variety of colors, such as white, gray, brown, and black.
- These small squirrels are great tree planters. When they bury their nuts, forgotten nuts become oak trees.
- If a squirrel falls, it can safely descend from about 30 feet.
- Squirrels can recognize humans.
Where do squirrels live?
- Squirrels are found on every continent except Australia and Antarctica.
- Tree squirrels usually inhabit wooded areas because they prefer living in trees.
- Ground squirrels live on the ground, where they dig burrows, a system of tunnels underground, to live in. Some ground squirrels enter a hibernation state in burrows during winter for warmth.
- Flying squirrels make their homes in tree holes or nests built in branch crooks. To move from tree to tree or from tree to the ground, flying squirrels spread the membrane between their legs and body and glide through the air. They can glide up to 160 feet (48 meters) high, making them appear capable of flying.
Food of squirrel
- On average, squirrels consume about one pound of food per week, but what do squirrels eat?
- Many people believe that squirrels only eat nuts, but this is not true. squirrels are omnivorous animals, meaning they enjoy eating both plants and meat.
- Squirrels primarily eat fungi, seeds, nuts, and fruits, but they also consume eggs, small insects, larvae, small animals, and even small snakes.
- In preparation for colder months, squirrels bury their food. During winter months, they have a food stash they can consume when supplies are scarce.
Baby squirrels life
- Females carry their young for a period ranging from 29 to 65 days, depending on the species; smaller squirrels have shorter gestation periods, according to the University of Michigan’s Animal Diversity Web.e
- Mothers give birth to two to eight offspring at a time. The offspring, called “kits,” are born blind and rely on their mothers for approximately two to three months.
- After seven to eight weeks, the kits are weaned. When they leave the nest, they do not travel more than two miles from home.
- Some squirrel species give birth to a new litter every few months or twice a year.
Lifestyle of squirrel
- Instead of hibernating, tree squirrels hide in nests or dens in trees during winter and feed for warmth. Most tree squirrel nests are called dreys, consisting of compact clusters of leaves, branches, bark, algae, and other compressed materials with tree foliage.
- These nests are visible from the ground, making the creature vulnerable to predators that could raid and snatch the inhabitant. Typically, adult tree squirrels live alone but occasionally nest in groups.
- Flying squirrels cannot fly in the same way as birds or bats but glide from one tree to another aided by the patagium, a furry membrane resembling a parachute that extends from the wrist to the ankle.
- It’s easy to distinguish between different squirrel groups: when a tree squirrel is alarmed, it usually climbs to the tree’s top, whereas a ground squirrel typically retreats to an underground burrow.
- Throughout the day, squirrels engage in activities such as running to find nuts and navigating up and down trees.
- Rodents have a natural appetite for various fruits, flowers, vegetables, fungi, nuts, trees, plants, and local insects.
- Before winter arrives, squirrels gather nuts, berries, buds, and tree bark and store them in shallow holes near trees.
- They also spend much of their time during the day gathering nest materials. The night is reserved for sleeping, and they can be found underground, in burrows, or atop trees.
- squirrels have various calls, including territorial barking or even “chuck” sounds. However, they primarily communicate through their tails, using them as a signaling device; they flick their tails if they’re uncomfortable or suspicious. Like dogs, they mark their territories with urine.
- Another interesting way squirrels recognize each other is through food and scent.
The most famous species of squirrel
1. Gray :
They are entirely gray except for brown touches on their face, feet, and tail. Gray squirrels are particularly acrobatic and can be seen anywhere from the ground to the treetops in deciduous and mixed forests.
2. fox squirrels :
Among the largest squirrel species, weighing about 2 pounds. Their colors vary from region to region, but most squirrels of this type have distinctive orange trimmings on their sides and tails. These squirrels live on the ground as they are not as agile as gray squirrels.
3. red squirrels :
Small in size but the most active, noisy, and colorful group of tree squirrels. They have large patches of red color and are found in pine forests feeding on cone seeds.
4. flying squirrels :
Their large eyes aid them in seeing in the dark, and the excess skin allows them to glide from one tree to another. They are among the most beautiful squirrel species. Although common, people do not see flying squirrels as often as other tree squirrels because they are primarily nocturnal.
5. ground squirrels:
Generally, they outnumber tree squirrels, and some have much shorter tails. When threatened, these squirrels rush to their burrows (or to a tree if they’re in a pinch). Ground squirrels tend to live in small underground colonies and are active during the day.
Finally
The biggest threat to squirrels is a virus called squirrel pox. Interestingly, the virus affects gray and red squirrels differently. While it is lethal to red squirrels, gray squirrels have developed immunity to the disease after years of exposure. Grays are primarily carriers and can spread the disease to red squirrels. The virus can spread through contact with infected lesions or contaminated scabs. Road traffic accidents pose another threat to squirrels. Of course, predators pose a danger to these younglings. For example, in North America, snakes, raccoons, red foxes, gray foxes, cats, and birds of prey are predators of gray squirrels.
