Decoding Squirrel Behavior: What is the 579 Rule for Squirrels?
The “579 rule for squirrels” doesn’t exist as a scientific or officially recognized term. Instead, it’s a humorous, anecdotal observation regarding their erratic and seemingly random movements: they run 5 steps, stop for 7 seconds, and then run 9 more steps.
Understanding Squirrel Behavior: Beyond the Myth
While the “579 rule for squirrels” is more of a lighthearted joke than a scientific principle, understanding the motivations behind squirrel behavior provides valuable insights into their survival strategies. Squirrels, especially in urban environments, exhibit a fascinating blend of innate instincts and learned adaptations.

The Roots of “Erratic” Movement
The “5-7-9” observation highlights what humans perceive as erratic movement in squirrels. But is it truly erratic? Consider these factors:
- Predator Avoidance: Squirrels are prey animals. Their primary concern is avoiding predators like hawks, cats, dogs, and even larger birds. Short bursts of speed followed by pauses for observation are crucial for survival. This “run-and-scan” approach allows them to assess potential threats effectively.
- Navigational Challenges: Unlike humans who rely heavily on visual landmarks and maps, squirrels navigate using a complex combination of scent, spatial memory, and learned routes. Short runs and stops allow them to recalibrate their position, especially in areas with dense foliage or urban obstacles.
- Food Security: Squirrels are constantly searching for food. Their foraging behavior involves inspecting potential food sources, burying caches (scatter hoarding), and remembering where they’ve hidden their treasures. Stops are necessary to assess the edibility of potential finds or to pinpoint the location of a buried nut.
- Communication: While less obvious to humans, squirrels communicate through vocalizations, scent marking, and body language. Short pauses may be used to listen for alarm calls from other squirrels or to signal their presence.
Adapting to Urban Environments
Urban squirrels have adapted remarkably to human presence. They’ve learned to:
- Exploit human food sources: This includes bird feeders, garbage cans, and even handouts.
- Navigate man-made structures: They use fences, power lines, and buildings as pathways.
- Tolerate human proximity: Although they remain wary, urban squirrels are generally more habituated to people than their forest-dwelling counterparts.
These adaptations contribute to the perception of their behavior as “erratic,” as they are constantly balancing the need for food and safety in a complex environment.
Common Misconceptions About Squirrels
Several misconceptions contribute to the perceived oddness of squirrel behavior:
- Squirrels are purely driven by instinct: While instinct plays a role, squirrels are also intelligent animals capable of learning and problem-solving. They can learn to open bird feeders, navigate complex mazes, and even anticipate human behavior.
- Squirrels are solitary creatures: While they don’t live in structured social groups like ants or bees, squirrels do interact with each other, especially during mating season and when defending territories.
- Squirrels forget where they bury their nuts: Studies have shown that squirrels possess exceptional spatial memory, enabling them to recover a significant portion of their buried caches. They use a combination of scent and landmarks to locate their hidden treasures.

Frequently Asked Questions About Squirrel Behavior
Why do squirrels run in short bursts and then stop?
Squirrels run in short bursts and stop primarily for predator avoidance. This “stop-and-go” technique allows them to quickly assess their surroundings, detect potential threats, and change direction if necessary, making it harder for predators to track them.
Do squirrels really remember where they bury all their nuts?
While squirrels may not remember every single nut they bury, they have an impressively strong spatial memory that helps them recover a large percentage of their caches. They use a combination of scent, landmarks, and spatial relationships to locate their hidden treasures.
Are squirrels dangerous to humans?
Generally, squirrels are not dangerous to humans, but they can bite if they feel threatened or cornered. It’s best to observe them from a distance and avoid direct contact. They can also carry diseases, although the risk of transmission is low.
Why do squirrels chatter and make other noises?
Squirrels use a variety of vocalizations, including chatters, barks, and trills, to communicate with each other. These sounds can signal alarm, attract mates, defend territory, or simply express excitement.
Are squirrels considered pests?
Whether squirrels are considered pests depends on the context. While some people enjoy watching them in their yards, others find them destructive, especially when they damage gardens, bird feeders, or even enter homes.
What is the best way to deter squirrels from my bird feeder?
There are several methods to deter squirrels from bird feeders, including using squirrel-proof feeders, baffles, or feeders with cages around them. You can also try offering them their own food source away from the bird feeder, such as corn on the cob.
Do squirrels hibernate in the winter?
Squirrels do not hibernate in the traditional sense, but they do become less active during the winter. They rely on their stored food caches to survive and may spend much of their time in their nests (dreys) to conserve energy.
What do squirrels eat besides nuts?
Squirrels have a varied diet that includes nuts, seeds, fruits, berries, fungi, insects, and even occasionally bird eggs. They are opportunistic feeders and will consume whatever food is available to them.
How long do squirrels live?
In the wild, squirrels typically live for 2-5 years. In captivity, they can live much longer, up to 10 years or more, due to a lack of predators and a consistent food supply.
Why do squirrels bury nuts in the first place?
Squirrels bury nuts and other food items as a survival strategy called scatter hoarding. This allows them to create a dispersed food supply that they can access during times of scarcity, such as winter or periods of drought.
Are all squirrels the same?
No, there are many different species of squirrels, each with its own unique characteristics and behaviors. Some common types include gray squirrels, red squirrels, fox squirrels, and flying squirrels.
What role do squirrels play in the ecosystem?
Squirrels play several important roles in the ecosystem. They help to disperse seeds, contributing to forest regeneration. They also serve as a food source for predators and can help to control insect populations. Their digging activities can also aerate the soil.
