While it is often associated with parks or forests, its life is full of fascinating details that are worth discovering. From the species' characteristics and interesting facts to its preparations for winter, this text will shed light on the secrets of these agile tree-dwellers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The common squirrel and the red squirrel \u2013 species characteristics<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In Poland, the most commonly encountered squirrel is the red squirrel, also known as the Eurasian red squirrel (Sciurus vulgaris). Its characteristic red fur, which becomes even denser in winter, protects it well from the cold. An adult squirrel measures between 20 and 24 cm, and its tail \u2013 between 17 and 20 cm \u2013 is its most recognisable feature, allowing it not only to maintain balance during leaps but also to keep warm on cold days.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Can you encounter grey squirrels in Poland?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The grey squirrel (Sciurus carolinensis) is an invasive species native to the eastern United States and southeastern Canada. It arrived in Europe through introductions, mainly in Italy, Great Britain, and Ireland, where it began to compete with the native red squirrel. The grey squirrel does not naturally occur in Poland, although there are a few instances of captive breeding and sporadic reports of its presence, mainly based on illegal releases. This species is larger and heavier than our native Eurasian red squirrel, and its fur has a characteristic greyish hue, sometimes with a mix of black or red. The grey squirrel reproduces quickly, is very opportunistic in its diet, and can inhabit a variety of environments \u2013 from deciduous forests to urban areas and gardens. Its presence in Poland poses a potential threat to the Eurasian red squirrel through competition, disease transmission (e.g., squirrel poxvirus), and damage to trees. Therefore, the breeding and trade of this species in Poland are subject to restrictions, and experts emphasise the need to monitor the situation, as natural expansion of the grey squirrel from neighbouring countries could become a reality in the near future.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara.jpg\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"521\" src=\"https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara-1024x521.jpg\" alt=\"wiewi\u00f3rka szara\" class=\"wp-image-4358\" srcset=\"https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara-1024x521.jpg 1024w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara-300x153.jpg 300w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara-768x391.jpg 768w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara-18x9.jpg 18w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara-600x306.jpg 600w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/wiewiorka-szara.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Where does it live and how does it behave?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The common squirrel is an animal that copes brilliantly in various conditions. In the wild, it inhabits deciduous and coniferous forests, and in large cities, it gladly appears in parks and gardens. It often climbs trees, using its beautiful, fluffy tail as a counterbalance and a tool for communication. Additionally, squirrels build nests, which they can move if threatened, using them as backup hiding places.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is a squirrel? The diet of squirrels is not just nuts!<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A squirrel's diet is incredibly varied. Their main food sources include seeds, hazelnuts or walnuts, acorns, tree buds, young tree shoots, mushrooms, and forest berries. During the autumn and winter months, they store extensive food reserves, burying them in various locations. This scatter-hoarding strategy, which involves spreading out their supplies, helps them survive the harshest months \u2013 thanks to it, squirrels can find food even months after hiding it. They also sometimes turn to insects, bird eggs, or bark, which demonstrates their remarkable flexibility in food selection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How do they gather provisions for winter?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In autumn, squirrels become real hoarders. They search for and store nuts, chestnuts, acorns, and mushrooms, which they hide in various places. Their spatial memory and sense of smell are so well-developed that they can find most of their caches even after a long time. Thanks to this ability, they not only survive the winter, but also contribute to the development of new plants by scattering countless seeds and nuts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Do squirrels hibernate?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The common belief about squirrel hibernation is mistaken \u2013 squirrels do not go into a full winter sleep. However, they are most active at dawn, moving around in search of hidden supplies, and afterwards they hide in their nests, which are often moved multiple times if threatened. On cold days they may warm each other by sitting together in the nest, although they usually lead a solitary life.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Squirrel as a pet \u2013 is it possible to keep one at home?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">More and more wildlife enthusiasts are considering keeping squirrels as pets. However, such a decision requires great responsibility and knowledge of the animal's needs. A pet squirrel is lively, curious about the world, and requires secured space to prevent damage to furniture or escape. They feed mainly on grains, nuts, fruits, vegetables, and even small insects and bird eggs. In Poland, keeping such animals is only legal under specific conditions, and caring for them requires specialist knowledge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A domestic squirrel is usually an animal from breeding or a species accustomed to living in residential conditions, for example, the Siberian chipmunk, also known as a chipmunk, which differs from the common European squirrel in appearance (it has a different fur colour, a striped back) and character traits. A domestic squirrel is more tame, although still lively and curious, requires a lot of space, and caring for it is similar to looking after other rodents. It lives for about 5-7 years and can be active during the day.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the common grey squirrel, which lives in the wild, leads a solitary life, is more cautious, is not domesticated, and should not be taken from the wild, as it can carry diseases. Its appearance is most often red fur and a bushy tail that tapers to a point. A wild squirrel is not adapted to living in a house and is difficult to tame.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek.jpg\"><img decoding=\"async\" width=\"1024\" height=\"578\" src=\"https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek-1024x578.jpg\" alt=\"\" class=\"wp-image-4359\" srcset=\"https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek-1024x578.jpg 1024w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek-300x169.jpg 300w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek-768x433.jpg 768w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek-18x10.jpg 18w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek-600x339.jpg 600w, https:\/\/turdus.pl\/wp-content\/uploads\/2026\/01\/gniazdo-wiewiorek.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Squirrel nests in Poland \u2013 habitat<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Squirrels build their nests (called \u201edreys\u201d) mainly in trees, using branches, leaves, mosses, and grasses. These are often spherical structures well hidden in the treetops, providing them with shelter from wind and rain. In Poland, common squirrels favour deciduous and coniferous trees where they can find suitable building materials. These nests serve not only as resting places but also as safe havens for young during the breeding season. Squirrels take great care of their nests' condition and can rebuild or relocate them if necessary.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>10 fascinating facts about squirrels<\/strong><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>There are over 265 species of squirrels in the world, and in Poland, the common or Eurasian red squirrel can be found, easily recognisable by its reddish colour and bushy tail.<\/li>\n\n\n\n<li>Squirrels have only four toes on their front paws, and together with five toes on their hind paws, they are excellent at gripping branches and food.<\/li>\n\n\n\n<li>Incisors grow by a few millimetres a week on average throughout their lives and are extremely hard, making them ideal for cracking nuts.<\/li>\n\n\n\n<li>Squirrels can jump distances of up to 6 metres, using their strong hind legs and agility, which allows them to perform spectacular acrobatics in the treetops.<\/li>\n\n\n\n<li>A squirrel's tail has various functions \u2013 it helps maintain balance, is used for communication, and in winter, it keeps the animal warm when the squirrel curls up into a ball, covering its body with its tail.<\/li>\n\n\n\n<li>Contrary to popular myth, squirrels do not hibernate but actively forage for food all year round, utilising their dried stores.<\/li>\n\n\n\n<li>Squirrels are so clever that they can learn the most efficient routes to food, bypassing obstacles and using various shortcuts.<\/li>\n\n\n\n<li>Male squirrels can detect a female in heat from a distance of up to one kilometre, which is important in their reproductive lives.<\/li>\n\n\n\n<li>Squirrels have the ability to rotate their ankles 180 degrees, which allows them to climb down trees headfirst, a unique ability among mammals.<\/li>\n\n\n\n<li>Squirrels sometimes gnaw on the bones of other animals to supplement their calcium intake, which is unusual for rodents.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FAQ \u2013 Frequently asked questions<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">How long does a squirrel live?<br>The average lifespan is around 3-4 years, although in natural conditions they can live up to 6 years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A squirrel.<br>Mainly seeds, nuts, buds, fruits, fungi, and sometimes insects and bird eggs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Does a squirrel sleep in winter?<br>No, it doesn't hibernate, but it is less active and spends time in its nest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The red squirrel can be recognised by its reddish-brown fur, which can vary in shade, and a bushy tail. It also typically has ear tufts, especially noticeable in winter, and a white belly.<br>This is the most common species with reddish-brown fur, which becomes denser in winter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Can you keep a squirrel in your home?<br>Yes, but it requires a lot of knowledge and the right conditions, as they are very active animals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Squirrels are fascinating animals with clever habits, and their role in the natural environment is incredibly important. By gathering provisions, they not only survive the winter but also support the development of forests. Learning about their habits and needs allows for a better understanding of these agile rodents and an appreciation of their unique position in nature.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By caring for the natural environment of squirrels, we help preserve the biological diversity and beauty of our forests for future generations.<\/p>","protected":false},"excerpt":{"rendered":"<p>Wiewi\u00f3rka to jedno z najbardziej rozpoznawalnych dzikich zwierz\u0105t w Polsce.
