I was home sick from work when i heard something hit my window. I got up to investigate and found a mother squirrel standing on her hind legs peering in to my window! I had seen the squirrel earlier in the week eating out of my bird feeder. I snapped the photo and she ran up the tree next to my feeder and i realized the feeder was now empty! I can take a hint! i realized she was probably trying to tell me to fill the feeder back up! I guess i should buy squirrel feed next time!
