Baby Squirrel Age Chart Pictures: Understanding Growth and Development

Baby squirrels, like many other mammals, go through distinct stages of growth and development. These stages are crucial for their survival and well-being, and understanding them can help in providing the best care for these adorable creatures. In this comprehensive guide, we will provide a detailed age chart for baby squirrels, complete with pictures and descriptions of each developmental stage.

Baby Squirrel Development

Squirrels are fascinating creatures, and their early life stages are full of rapid growth and changes. Knowing how to identify the age of a baby squirrel can be vital for anyone involved in wildlife rescue, rehabilitation, or even just observing these animals in their natural habitat. This age chart will help you understand what to expect at each stage of a baby squirrel’s development.

Newborn to One Week Old

Physical Characteristics

Newborn squirrels are born hairless, blind, and deaf. They are incredibly tiny, usually weighing between 10 to 15 grams. Their skin is pink, and their limbs are not yet fully developed. At this stage, they are entirely dependent on their mother for warmth and nutrition.

Behavior and Care

Newborns spend most of their time sleeping and nursing. They need to be kept warm as they cannot regulate their body temperature. If you find an abandoned newborn squirrel, it’s crucial to provide immediate warmth and contact a wildlife rehabilitator.

Two to Three Weeks Old

Physical Characteristics

By the second week, baby squirrels start to develop a light layer of fur. Their eyes and ears are still closed, and their skin begins to turn grayish. They typically weigh between 25 to 30 grams at this stage.

Behavior and Care

Squirrels at this age are still very dependent on their mother. They begin to wiggle more and can make soft squeaking noises. They should be fed every few hours if they are orphaned, and their environment must remain warm and secure.

Four to Five Weeks Old

Physical Characteristics

At four weeks, baby squirrels’ fur becomes more noticeable, and their eyes begin to open around the fifth week. Their ears will also start to unfold. They weigh between 35 to 50 grams. The development of their tail fur begins, giving it a bushier appearance.

Behavior and Care

With their eyes open, baby squirrels become more curious and start to explore their surroundings. They require frequent feeding, usually every 3-4 hours, and their diet can slowly be supplemented with small amounts of soft foods.

Six to Seven Weeks Old

Physical Characteristics

By six weeks, baby squirrels have a full coat of fur, and their eyes and ears are fully open. They weigh around 70 to 80 grams. Their tail becomes bushier, and they start to resemble miniature versions of adult squirrels.

Behavior and Care

At this stage, baby squirrels become more active and playful. They can start to eat solid foods like nuts and fruits but still need regular formula feedings. They also begin to practice climbing and jumping, honing their motor skills.

Eight to Nine Weeks Old

Physical Characteristics

At eight weeks, baby squirrels are significantly more robust and agile. They weigh between 100 to 150 grams. Their teeth are fully developed, and they start to shed their baby fur, replacing it with adult fur.

Behavior and Care

Squirrels at this age are very active and need plenty of space to climb and explore. They can eat a variety of solid foods but should still receive some formula. It’s essential to start preparing them for release if they are being rehabilitated.

Ten to Twelve Weeks Old

Physical Characteristics

By ten weeks, baby squirrels are nearly indistinguishable from adults, although they are still smaller. They weigh between 150 to 200 grams. Their fur is thick and glossy, and they are fully capable of independent movement and foraging.

Behavior and Care

Squirrels at this age are ready to start living independently. They should be introduced to an outdoor environment gradually to acclimate them to the weather and natural food sources. If being released, it’s best to do so near the location where they were found.

Thirteen Weeks and Beyond

Physical Characteristics

At thirteen weeks and older, squirrels are fully grown and weigh around 250 grams or more. They have fully developed teeth, fur, and claws, making them adept climbers and foragers.

Behavior and Care

These young squirrels are now capable of surviving on their own in the wild. They should be released in a safe and suitable habitat where they can find food and shelter. Continued monitoring can ensure their successful transition to independent living.

Conclusion

Understanding the growth and development of baby squirrels is crucial for their proper care and rehabilitation. By following this age chart and providing the necessary support at each stage, you can help ensure these delightful creatures grow up healthy and strong.
