Kahu, the Harrier Hawk is the species and they patrol relentlessly in search of Food. I have a very large old Tree Stump that stands 8 foot high.
On top of this I plan to build a Birds Nest, along with Rhea and Ostrich Eggs ... perhaps some Opossum Fur (like roadkill) in a bid to entice them near ... Eggs, Chicks, Piglets and Roadkill are the most popular diet for the Kahu.
