So I have called him Zebedee after the magic roundabout. He has survived 2 nights of below freezing temperatures - comes to feed 3 or 4 times a day, I can hear the beep beep beep when he is on his way and he is tenacious. The sparrows have respect! Still not sure if I should do anything - but I figure he is doing pretty well looking after himself.
Anyone have any idea if I should do something - he seems so happy.
