me too smudge. what they do when i cant see em is another thing.A moral dilemma. If you saw a Sparrow Hawk sitting on your back fence eying up some Bluetits on the feeders, would you shoo it off with the possibility the hawk or it`s youngsters would go hungry? I personally would shoo it off but is that the right thing to do? I know it has to kill, but i couldn`t stand by & watch it kill another little bird in my garden.
