There was 2 of these in the tree outside my window this morning making a god awful noise & I could hear the snap & clash of beaks as the magpies dove in & out like stukas.
No idea what they are, but at 6:30am, I didn't really care, I just wanted them to go away & let me go back to sleep 
As for the quality of the shots, well, I make no claims about that, I've never claimed to be a wildlife photographer 
But more importantly, what are they?? Why do the maggies hate them so??
but, if you're in the top part of Australia or down the east coast it could be a Channel-billed Cuckoo - it's the nearest thing I can find.
