Terry Pacey's piece about the butcherbird devouring the Noisy Miner has
reminded me of a similar observation in my back yard.
  I went outside a couple of days ago to see what had made the loud thud, 
somewhere near our door, and saw a Peaceful Dove flying away (with a 
stray feather floating on the breeze) and "our" handreared, semi-wild 
Magpie in hot pursuit.
 When I followed them into the nearby trees I found the maggie sitting on 
the now-dead dove. Magpie was in the crouching, wings out, tail and head 
up, posture, fluttering and chirping in a juvenile-type manner (She's 
over a year old). I picked her up, acertained that the dove was dead 
then decided to let nature take its course and put the maggie down 
again. When I left her she was pulling feathers out of the dove.
 Was the maggie being opportunist - chasing down an already 
stunned/injured dove and (maybe) finishing it off, or did she attack the 
dove in the first place? We'll never know, but I did find her in 
similarly compromising circumstances 3 weeks ago, perched on a fledgling 
Spiny-cheeked Honey-eater with 2 distraught parent honey-eaters 
attacking her. They flew off when I approached and I confiscated her 
(alread dead) prey on that occasion, hoping to discourage her from such 
activity, but apparently it didn't work.
 I hope I haven't reared a "rogue" magpie! At least it confirmed what I 
already knew -  she isn't dependent on us for food!!
 Several years ago I also witnessed another adult magpie chase, kill and 
eat a fledgeling House Sparrow.
