For extinct harrier see http://nzbirdsonline.org.nz/species/eyles-harrier and the eagle http://nzbirdsonline.org.nz/species/haasts-eagle
Re NZ Falcon - It occurs in the area where I filmed this bird, and I have seen it there. Totally different, something between an Australian Hobby and a Peregrine in size and habit. I have held a tame male and female NZ falcon trained for falconry on my arm, female is much bigger, Normal food are small/medium birds. Has apparently adapted to living in the vast commercial pine plantations in this area.
Re carrion - don't forget the Moa and that Eagle. Possums can be super abundant, authorities use 1080 in industrial quantities to keep them down, often applied by helicopter over large areas, not popular with some. In forests in the central north island that I have known over the last 10 years there there seems to be less of them about now, e.g. given the level of road kill currently to be seen on the busy roads compared to previously - car numbers have not dropped! Seen the odd wallaby to and there are rabbits and big birds such as feral turkey and plenty of sheep. Possums, stoats and rats are the main mammalian threats to birds there - esp. given they can climb trees to get eggs and nestlings, which are vastly more vulnerable than the adults. Degree to which individual species can cope with these predators varies between native species, some cannot cope at all, others can cope a bit and some seem to do OK in areas where little or no pest control is undertaken.
