The Squirrels of Denver

If you’ve noticed squirrels darting through your yard, you may have wondered whether you’re spotting grey or red squirrels. While both species are common throughout the Denver area, they each have unique traits that make them fascinating to observe—and potentially challenging for homeowners. This article breaks down the key differences between these species, offering insights into their appearance, behavior, and the risks they might pose to your home. Whether you’re curious or concerned, let’s explore this red and grey squirrel comparison to help you identify and understand these bushy-tailed visitors.

Grey vs Red Squirrel Differences
When it comes to distinguishing between grey and red squirrels, their physical and behavioral differences are the first places to start. Here’s how you can identify each species:

Appearance
Grey squirrels are larger than red squirrels, weighing between 14 to 21 ounces and measuring up to 20 inches from nose to tail. Their fur is predominantly gray with white underbellies, and they often have bushier tails.
Red squirrels, on the other hand, are smaller, typically weighing 7 to 10 ounces and measuring around 12 to 14 inches in total. Their fur is a distinct reddish-brown colour with a white underbelly, and they often have tufted ears during the winter months.

Behavior
Grey squirrels are highly adaptable and thrive in urban and suburban areas like Denver. They’re bold and curious, often seen raiding bird feeders or darting across power lines.
Red squirrels are more territorial. They are likely to chase away other squirrels from their area, and you’ll find them in wooded settings where conifer trees are abundant.

Habitat
Grey squirrels are tree dwellers and make their homes in deciduous forests, parks, and residential neighbourhoods. Surrounding trees near Denver’s Cheesman Park or Washington Park are ideal habitats for them.
Red squirrels prefer coniferous forests and are less likely to venture into heavily urbanized locations, although you might spot them along the trails near Rocky Mountain National Park.
