Cock Robin's return.

I have not seen my regular Robin for a while.It is still picking up food and flying off with it! 
   I think it may have a 2nd nest somewhere as I think the Magpies and Jays got at the last one?
  The small birds have had a hard time of it this year.But of course we have an abundance of Maggies and Jays!  It is nature's way I suppose?
