still hunt singly, even though its numbers in such an area would increase considerably. It is a silent, lone hunter and very very seldom makes any call at all, even when wounded. At the mating season it might hunt in pairs but even that I doubt. Birds, though not exactly birds of territory, defini- tely favour certain areas for hunting and when once seen in an area hunting (not soaring or playing high on the wing above the tree tops) it is always worth remembering when later in that area and keep a good look out and the bird will often be seen there again. Probably it has a more or less regular routing round each day it hunts till it gets its fill, as it is noticeably it is generally seen in the same place about the same time on different days. Of course if it gets a kill early on the round the rest of the round is upset. After a kill it generally makes for a secluded spot near at hand, perches for 10 or 15 minutes, then flies off and commences playing on updrafts of air and soaring about sometimes for 2 hours and more at a stretch and generally over 1 hour, sometimes taking short rests. It then recommences hunting and if successful does the same again. I have never seen the bird over the sea nor does it hunt very close to the sea, (seldom if ever closer than 150 yards from tide mark) but it will cross inland small sheets of water, tidal lagoon arms etc. and hunts right along the water's edge of such places. Possibly the movement of small waves alarms it, most movement does, and only where waters are calm and still in such places as these lagoon arms will it approach it. The species breeds on the island but was not breed- ing during my time on the island. July, August, September are
