Tree squirrel

Tree squirrels live in trees.

They are very good at climbing. Most live in trees, but some live in holes in the ground.

These animals like to chew on things. Their teeth never stop growing. Chewing helps keep their teeth short.

They often hide food in the dirt. They use their noses to find it later. This can make a mess in a garden.

Some squirrels live in cities. They can even live in our yards. They like to visit bird feeders for a snack.

Squirrels are very busy and smart animals.

Tree squirrels are part of the squirrel family.

There are more than 100 types of tree squirrels. They live on every continent except Antarctica and Oceania. These animals are called arboreal. This means they live mostly in trees.

Some squirrels, like flying squirrels, have special skin. This skin works like glider wings.

Squirrels are very busy and smart. They like to chew on many things. This helps their teeth stay sharp. Their teeth grow all the time.

Squirrels also hide food in the ground. They use their strong sense of smell to find it later.

Many squirrels live in cities and parks.

They can learn to find food from people. Some people even keep them as pets. In the past, people in Europe kept them on leashes. Squirrels can also be a problem for homes. They might build a nest, called a drey, in an attic. They might even chew on wires. This can cause fires or power outages. In some places, people hunt squirrels for food. Some people even use their fur for fishing.

Tree squirrels are members of the squirrel family called Sciuridae.

There are more than 100 different species that live in trees. These animals live on every continent except Antarctica and Oceania. They are not one single group of relatives. Instead, they are related to ground squirrels, chipmunks, and marmots. We call them tree squirrels because they live in trees rather than in holes in the ground.

One special type is the flying squirrel. It has flaps of skin called patagia. These act like glider wings to help it fly through the air.

Squirrels have a very busy way of living. They are known for being inquisitive and persistent. One important thing they do is gnaw on objects.

This chewing is not just for fun. A squirrel's teeth grow all the time. Gnawing helps keep their teeth from growing too long. They also like to bury food in the ground. They use a keen sense of smell to find these hidden snacks later. Sometimes, they might even chew through metal or plastic to reach food.

People have lived alongside squirrels for a very long time. In Western society, people kept them as pets until at least the 19th century.

Because they are small and tame, they were popular with women and the clergy. In the Middle Ages, people even hunted red squirrels for their blue-gray winter coats. This special fur was called vair. Today, many species have moved into human areas. They live in suburban backyards, rural farms, and busy urban parks.

There are many different groups of tree squirrels in the world.

Scientists use genetic data to sort them into subfamilies. One group is the Sciurinae, which includes mostly American tree squirrels. Another group is the Callosciurinae, which contains Asian tree squirrels. Some species, like the Asian palm squirrel, were moved to Australia in the 1920s. The Eastern gray squirrel is another famous type. It was brought to Great Britain in the 1870s. These different groups help us understand how squirrels spread across the globe.

Squirrels can sometimes cause big problems for people. They build nests called dreys in attics or sheds.

Squirrels might chew on power cables like they are tree branches. This can cause short circuits or even fires. They have even caused issues with the NASDAQ stock market. In some places, people hunt them for food. In the Southern US, squirrel meat was used in Brunswick stew.

In the UK, people are now cooking the invasive gray squirrel as a fashionable meat. Even though they can be pests, they are a fascinating part of our world.

Tree squirrels are members of the squirrel family known as Sciuridae.

While they are often just called "squirrels," they do not form a single natural group. Instead, they are related to various other animals like chipmunks, marmots, and ground squirrels. The term "tree squirrel" is based on their habitat rather than their physical traits. These animals live mostly among trees rather than in burrows in the ground or among rocks. There are more than 100 arboreal species found on every continent except Antarctica and Oceania.

One fascinating exception to the standard tree squirrel body plan is the flying squirrel. Although it lives in trees, it possesses a unique physiological feature called patagia. These are special flaps of skin that act like glider wings. This allows the animal to perform gliding flight between trees. Most other tree squirrels rely on expert climbing skills to move through their environments. Many species have also adapted to live in human-altered areas like suburban backyards and urban parks.

Scientists use genetic data to classify tree squirrels into several distinct subfamilies. One major group is the subfamily Sciurinae, which includes the genus Sciurus. This genus contains well-known animals like the North American fox squirrel and the Eurasian red squirrel. Another group is the subfamily Callosciurinae, which consists of Asian tree squirrels. This group includes the genus Funambulus, such as the Asian palm squirrel. The Asian palm squirrel was introduced to Australia in the 1920s.

Other subfamilies include Ratufinae, which contains the Asian giant squirrels, and Xerinae, which includes African tree squirrels.

Squirrels have a very specific way of interacting with their environment through gnawing. Their teeth grow continuously throughout their lives. Because of this, they must chew on objects to prevent their teeth from over-growing. This characteristic trait means they will gnaw on many different things to keep their teeth sharp. They may chew on tree branches, plastic, or even metal to reach food. This persistent behavior can sometimes make them a nuisance to humans.

For example, they may chew through bird feeders or garden items to find snacks.

In residential areas, squirrels can cause significant property damage and safety concerns. They build nests, which are called dreys, in places like attics, basements, and sheds. These nests can cause unpleasant odors, noise, and structural damage to a home. A serious risk involves electrical systems. Squirrels often treat exposed power cables like tree branches and gnaw on the insulation. This can lead to short circuits, power outages, or even fires. In fact, squirrels have been responsible for shutting down the NASDAQ stock market twice.

Humans have had a long and varied relationship with squirrels. In Western society, squirrels were kept as pets until at least the 19th century. They were especially popular with the clergy and women due to their small size. Historically, squirrels have also been hunted for food and fur. In the Middle Ages, the red squirrel was hunted for its blue-gray winter coat, known as vair. In the Southern United States, squirrel meat was a traditional ingredient in Brunswick stew.

Today, some people in the UK eat the invasive gray squirrel as a fashionable meat option.

While squirrels are often seen as pests, they are also part of the urban landscape. In many cities, squirrels have become desensitized to humans and can be hand-fed in parks. However, wildlife experts note that feeding them improper foods can be harmful. For instance, sunflower seeds and peanuts can lead to metabolic bone disease because they lack essential nutrients. In some areas, people even build special structures like the Nutty Narrows Bridge in Washington to help squirrels cross busy streets safely.
