Squirrels are (pesky) herbivores for North American gardeners at times. They dig (often in our flower pots), but also all over the garden; they scamper along fences, visit porches, and (in the bad old days, prior to the expensive gutter system, ran around in our attic).
I've been bemused by their radicchio-eating habits (at least by females), and there are current signs of interest, based on evidence, but I was amazed by this porch-visiting Eastern Gray Squirrel. We've had plenty of munching evidence in the past, but this was flagrant.
S/he was snagging leaves of a Boston fern on the porch, and sitting on the railing, as s/he enjoying eating it. A Boston fern? Who knew?
