Squirrels are common sights in many environments, from dense forests to suburban backyards. While their constant activity and foraging for food are readily observed, how these agile rodents fulfill their hydration needs is not always apparent. Understanding their water-seeking behaviors reveals a complex interplay between their environment, diet, and opportunistic adaptations.
Natural Water Sources
Squirrels primarily depend on naturally occurring water sources. They frequently drink from surface water bodies such as puddles, small streams, rivers, and ponds, lapping the water with their tongues. Even larger bodies of water like lakes can be accessed.
Precipitation also serves as a direct source of hydration. Squirrels will drink rainwater directly from surfaces like leaves or the ground after a shower. Additionally, they often lick dew from grass and plant leaves, especially in the early morning before it evaporates. This behavior allows them to obtain moisture without having to descend to ground level, offering a safer way to hydrate.
Some plant processes also contribute to their water intake. Squirrels may consume moisture from guttation, which are water droplets expelled from plant leaves due to root pressure. They might also chew on moist bark.
Water from Food Sources
A significant portion of a squirrel’s daily water intake comes indirectly from the food they consume. Many fruits and vegetables are rich in water content, providing hydration. Examples include berries, apples, and various mushrooms.
While nuts and seeds are generally drier, they still contain some moisture. Squirrels also chew on tree bark to access nutrient-rich sap, which provides both water and sugars, notably from maple trees. Young buds and flowers also contain moisture, serving as a supplementary water source during certain seasons.
Human-Provided Sources
In areas inhabited by humans, squirrels are opportunistic and readily utilize artificial water sources. Bird baths are a common point of hydration for squirrels, who frequently visit them for a drink. They can also be seen drinking from outdoor pet water bowls, demonstrating their adaptability to shared resources.
Leaky outdoor faucets or dripping hoses provide consistent, accessible water sources that squirrels will readily use. Similarly, runoff from irrigation systems can create puddles or wet areas where squirrels can find water. These human-made sources become especially important during dry periods when natural water might be scarce.
