Understanding what a newborn squirrel looks like can be helpful for identification. These small mammals undergo significant changes from birth to independence, making their early appearance quite distinct from their adult counterparts.
Physical Appearance at Birth
At birth, squirrels present a very specific appearance. They are small, typically weighing around one ounce and measuring about one to two inches in length, sometimes described as being about the size of a human thumb.
Their skin is pink and translucent, completely hairless. The eyes of a newborn squirrel are fused shut, appearing as small bumps, and their ears are flat against their head, not yet open.
Their tails are short and stubby, lacking the bushy fur characteristic of adult squirrels. They are entirely helpless, unable to move much on their own, and are dependent on their mother for warmth and care.
Early Growth and Development
As a newborn squirrel progresses through its first few weeks, its appearance begins to change. During the first two weeks, the skin may start to darken, transitioning from pink to a grayish hue as the initial fur begins to develop beneath the surface. While still largely hairless, faint whiskers may emerge, and their eyes and ears remain closed.
By the third week, a fine, downy fur starts to appear across their body, and the ears will typically begin to open. Between four and five weeks of age, their fur becomes thicker and more widespread, and their eyes will start to open. The tail also begins to lengthen and develop slight fluffiness during this period.
What to Do If You Find One
Should you encounter a seemingly abandoned newborn squirrel, initial assessment is important to determine if intervention is needed. Observe from a distance to see if the mother might return to retrieve her young, especially if the baby appears uninjured and the weather is mild. If the baby is cold, the mother will likely not retrieve it, so providing warmth can be crucial for reunification efforts.
If the squirrel is truly orphaned or injured, handle it with care, preferably wearing gloves to protect both yourself and the animal. Place the baby in a small box or container lined with a soft cloth and provide a temporary heat source, such as a warm water bottle wrapped in a towel or a sock filled with warm, uncooked rice.
Avoid giving the squirrel any food or water, as improper feeding can cause harm. Promptly contact a licensed wildlife rehabilitator in your area, as they possess the expertise and resources for proper care.
