Cuckoo tails

["Greg & Val Clancy" <>]

Bill,

I am 100% sure that the bird is an Australian race of the Shining 
Bronze-Cuckoo.  The purplish-brown head and nape make it the Australian 
race.  The New Zealand (nominate race) is very green on the head and nape 
and has a white line on the forehead which, if present, is narrow on the 
Australian bird.  The large amount of green on the wings and back rule out 
Horsfield's.  Also Horsfield's has a large amount of rufous in the tail.
Regards

Greg
