So, how does this squirrel high up a tree come to have the remains of a zested orange in his possession you ask?
Well, turned out I left the hole open. The critters don't pull much out except to get to the new stuff on top so there hasn't been much mess to cause me to issue a cease and desist order and plug the hole.
Orange zest? Well, this particular orange was used by Amy to fix some New Year's Day-vegan-chocolate chip-oatmeal cookies - which included zesting an orange skin.
He changed his sitting limb for this second image. I made both of them through double pane glass with the tree about 10-15 feet away.
