Nuts to You, Says Abert's Squirrel

Abert's squirrel in ponderosa pine.
Everyone thinks of squirrels as caching nuts (thus inadvertently planting trees), but not the Abert's squirrel of the Southern Rockies and Colorado Plateau.

They just eat their favorite tree, ponderosa pine, which happens to be my favorite tree too, although I rarely eat any parts. (The pollen is a tonic, though.) Colorado Parks and Wildlife says, "Abert’s squirrel does not hoard food, but eats whatever part of its host tree, ponderosa pine, is available in season: cones and inner bark of twigs."

Many are a sort of salt-and-pepper grey (like these), but in southern Colorado they are mostly black. I think I have seen one grey one near the house in twenty years.

This degenerate squirrel has abandoned its healthy wild lifestyle
to eat sunflower seeds under the bird feeder.
Its name is one of those 19th-century "Westward the course of empire" relics, for it is named after James William Abert—explorer (Corps of Topographical Engineers), artist, and Civil War staff officer.

James William Abert
As Lieutenant Abert roamed the West in the 1840s, his proud father wrote to John James Audubon, "My son, Lieut. A., has some taste for Natural History. He has just returned from Santa Fe, having been on General Kearney's expedition. . . "

Together with collecting specimens, he also discoursed in the 19th-century manner on color theory for artists interested in natural history.

You can see Lt. Abert's reconstructed room and sketchbook at Bent's Old Fort, where he (and Everyone who was Anyone) stayed c. 1846.

Having lived in Texas all my life I had never seen one of these until we got a cabin near Howard. First time I saw a BLACK squirrel I stopped the car, backed up to follow it, stared, tried to get my picture by it and then drove straight into Salida to the bookstore for a flora and fauna book. I think it may have been the animal that surprised me the most. The bears are a treat to see, mountain lions on the game camera are creepy but expected, the fox are cute but a black squirrel? I'd never heard of such a thing.

They are a little startling, the first time you see one!
