In the movie “UP,” one of my favorite recurring scenes is when someone shouts “squirrels!” and all the dogs go crazy moving in every direction hoping a squirrel is nearby. Most dogs who like squirrels would not be disappointed if they visited Rocky Mountain National Park. If I do not see any animals on my forays into the park, I always see at least one squirrel. Even in the quiet of winter, I can count on seeing squirrels in the park.
In the summer, four types of squirrels thrive: pine squirrels, Wyoming ground squirrels, golden mantle ground squirrels, and Abert’s squirrels.
Pine squirrels are common. These small rodents live in coniferous forests with pine, fir, and spruce trees. I often hear their chatter if I unknowingly get too close to their storehouses. Their tail helps them balance and provides warmth when they wrap it around their bodies in chilly weather.

Wyoming ground squirrels exist at the low altitudes of the park. Most Estes Park residents do NOT like them and wish they would just stay in the park. They burrow into the ground and look like prairie dogs except that they hibernate underground in the winter.
Golden mantel squirrels often are mistaken for chipmunks although they are larger and do not have stripes on their faces. They live primarily in rocky places in mid-elevations of the park. They also spend most of the winter in hibernation.
Abert’s squirrels are the most beautiful. They are black with tufted ears. They inhabit ponderosa pines in the montane areas. I see them least often among these squirrels and delight most in their unique black appearance, especially if contrasted against winter snow.
Squirrels eat seeds, nuts, and cones. They can also eat fungi, berries, and sometimes insects. One reason I see them so often in the park is that the Pine and Abert squirrels are active year around both during the daytime and at dawn and dusk.
Everywhere I have lived has had squirrels of varying species. I thought they were all brown like in Iowa until I saw the gray ones in North Carolina. Squirrels are not one of those animals that excite people when they are seen. The sightings of Bullwinkle the Moose get more attention than Rocky the Squirrel. Nevertheless, these small mammals are a part of this diverse ecosystem, and I can count on seeing them on every hike. Their contributions are underrated in this vibrant landscape.
