Squirrel Snackby Ralph S. Carlson
ABOUT THE ART
A grey squirrel snacks on the inner bark or cambium of a big cone pine in the Ranch Santa Ana Botanic Garden in Claremont, California. Internet searches brought the information that various squirrel species in North America have been observed eating the inner bark of many different species of trees, but the purpose of such feeding is still unclear. One theory is that, perhaps, female squirrels feed on the cambium to reduce abdominal cramping. Another theory is that squirrels are getting a desirable sweetness in their diet.
