We do also have a black bear, and I have seen one syphoning food out of a bird feeder, but still have to capture on film as they are more night creatures here, moving freely under cover of dark. The reason we know they are frequent visitors is because they are often kind enough to leave a calling card. I would have a picture if it weren't for the construction crew driving over the 'sample' last summer.
This picture, (at left) takes you to the other more aesthetically pleasing four legged creatures who pass through our yards, if you click on the photo.
