I have been in the garden a few weeks now working, and robins often come up to me and watch me work really close, bout a meter away. I held out a worm for it and it hoped onto a branch closer to me but just waited. Then it flew over to why my mother was working in the flowers and soil and sat on the floor looking at her. It is curious at how brave they are, they also hunt for worms right around us. So how can I get these birds to come and take the worms? also is there anyway of marking them so we know if it is the same one.
