Squirrels are without a doubt diurnal creatures. You will very rarely see a common squirrel out in the open after the sun goes down unless they have reason to flee their nests (like my front yard squirrels who run for cover under my neighbor’s truck every time it begins to rain, even in the middle of the night). During the hot summer months, squirrels become very crepuscular. Wait… huh? What in the hell does that funny word mean?
Crepuscular is an adjective used to describe things associated with twilight.
Crepuscular animals are most active during dawn and dusk. So you see squirrels out and about doing their regular business very early and late in the day during the warmer months. Hey, would you want to look for acorns when it’s 95 and the sun’s beating down on your fur? Animals aren’t officially classified as crepuscular like they are “diurnal” or “nocturnal” because it’s really a very loosely applied trait that is rarely consistent within any species.
Still, it’s fun to think of squirrels running around in the murky shadows of twilight time rather than in broad daylight. Whether the sun’s just coming up, or getting ready to set, look out for those fun loving Saturday Squirrels who come out to play in the twilight time!
Have a crepuscularly great weekend everyone!
