for me, a squirrel eating leaves. Watched this squirrel, sat on the fence, deliberately pull down a branch of the Maple and tear off some new growth with new leaves, and then methodically eat it all. Carole Googled and asked the following question "Do squirrels eat leaf?" and the answer we got back was "Known for nibbling nuts and gobbling birdseed, squirrels also like feasting on garden seedlings, fruits, berries, flowers, leaves, and tree buds"
