What does it mean if a squirrel stops and stares at you?

If a squirrel stops and stares at you, it is assessing you to determine whether you are a threat, a source of food, or something to ignore, and this behavior is a normal part of squirrel vigilance. Squirrels have excellent vision and are constantly scanning for predators like hawks, cats, and humans, so when they stop and stare they are freezing to get a better look and decide whether to flee, continue foraging, or approach. If you are in a park where people often feed squirrels, a squirrel that stops and stares at you likely associates humans with food and is hoping you will offer peanuts or other treats, and it may have learned that staring leads to feeding. If the squirrel is near its nest or babies, staring can be a warning that you are too close and it is keeping an eye on you to protect its drey. If the squirrel's tail is flicking rapidly and it is chattering, staring may be part of an alarm display signaling that you are perceived as a threat. Sometimes squirrels simply stare out of curiosity. In rare cases, a squirrel that stares for a very long time, appears unusually tame, lethargic, or aggressive, may be sick. Generally, a squirrel that stops and stares at you is not being aggressive but is being cautious and curious, evaluating your intentions before deciding what to do next.
