Crack for birds, that's what peanut butter is! Many times lately this nuthatch won't even wait for me to deposit the peanut butter. I think it's trying to get some before the woodpeckers and blue jays grab it all. It will fly down and land on the knife, or my wrist, or as in this case, hover for a moment, and grab a bite right off the knife!! This time I had a camera with me. This bird has absolutely no fear of me at all. I guess that's what an addiction can do to one. lol!
