One of the interesting parts of sitting in an office at the end of the garden (with floor to ceiling glass) is witnessing the array of garden wildlife that passes by unnoticed from the main house. For the last month the squirrels have been super busy gathering as many acorns as they can locate and hiding them in various spots around the garden. Just watched on digging into the ground, hiding the nut, covering in and then placing leaves over the hole. Genius.
