If there ever was a koekoeā heaven on earth this would be it.
Tall trees where the birds can keep an eye out for attackers.
This makes for an ideal calling ground.
When we took this image there was about 5-6 birds all calling to each other.
Every now and again one would fly to a tree where another was calling from.
more often than not that move cuased a screaming match with all the other birds screeching their approval.
