Squirrels require water for survival. While often seen foraging for nuts and seeds, their need for hydration is constant. Understanding how these agile creatures meet their water needs highlights their adaptability.
Why Water is Essential for Squirrels
Water plays many roles in a squirrel’s biological processes. It is involved in regulating their body temperature, especially during warmer periods. Squirrels do not sweat like humans, making internal temperature regulation even more dependent on water intake.
Water helps in the digestion of food, breaking down nutrients from their varied diet. It facilitates the absorption of these nutrients into their bloodstream. Beyond digestion, water is also involved in the elimination of waste products, maintaining kidney function. A squirrel’s kidneys are efficient at extracting moisture, enabling them to conserve water.
How Squirrels Obtain Water Naturally
Squirrels find water sources in their natural habitats. They commonly drink from natural bodies of water. Rainwater collected in leaves, tree hollows, or small puddles also serves as a source. In the early morning, squirrels can often be observed licking dew drops from leaves and blades of grass. This morning dew can contribute a notable amount to their daily water intake.
Much of a squirrel’s hydration comes from the food they consume. Fruits, vegetables, and other plant matter contain considerable moisture. Acorns can be over 50% water, and fungi like mushrooms have high moisture. During colder months, squirrels can obtain water by eating snow or licking ice. However, melting snow internally requires energy, making it a less efficient source compared to liquid water.
Supporting Squirrel Hydration
Providing a reliable water source can significantly benefit local squirrel populations, particularly during dry spells, heatwaves, or freezing conditions when natural sources become scarce. A shallow dish filled with fresh, clean water is a simple and effective method. Ceramic or heavy plastic bowls are suitable, and adding rocks or pebbles can create shallow areas, making it safer for smaller animals and insects to access the water and prevent accidental drowning.
Placement of the water source is also important; it should be in a safe, easily accessible location, preferably near trees or shrubs. This allows squirrels a quick escape route from potential predators.
Regular cleaning of the water dish is necessary to prevent the growth of bacteria and algae, which can be harmful. Changing the water daily, or more frequently in hot weather, ensures it remains fresh and appealing.
During winter, a heated birdbath or a de-icer can keep water from freezing, offering a continuous supply. While squirrels are adept at finding water, human assistance can be a valuable supplement to their hydration needs.
