Very nice photos Bookpossum, thanks for posting them.
As you will know these birds are quite threatened so not often seen in the wild. One of the isolated places we sail to in NZ has a small population of them and we occasionally see them hunting on the open hillsides (but have not seen them hunting in forests where they also hunt).
The most common raptor here is the much bigger swamp harrier which is distributed and common most everywhere (it established itself here from Australia in the distant past). As they will eat carrion we, when kids, used to try to snare them but without success; I have no idea how we would have handled one if we had been successful
.
The only other raptor here, apart from occasional visitors from Australia, is the Morepork (an owl, also found in some parts of Australia with a different common name). While not threatened they are not often seen, both because they are nocturnal and are a forest dweller. For many years the house we had was located just into the trees of the forest adjacent to the city we lived in; we would occasionally see them but very often hear their "more pork" calls at night close by, very noisy when several of them got fired up outside the bedroom window. There are some recordings of their unusual call at

But the birdlife here just cannot compare with that in Australia both in interest and diversity.
