30/5/38 1 Accipiter believe ♀, certainly adult hunting in tall coconuts (believe same bird as seen on 28/4/38, same area.) 4/6/38 2 adult ♀ and 1 adult ♂ Accipiter seen. ♂ hunting through low coconuts. 1 female perched watching domestic chicken, too quick off mark to shoot. 1 ♀ ad. seen soaring over tall coconuts groves. 7/6/38 2 adult ♀ and ad. ♂ seen, all hunting in tall coconuts or margins of such and swamp land. 8/6/38 1 Accipiter seen flying high over coconuts (large, believe ♀). 21/6/38 1 ♂ adult seen hunting through tall coconuts (same place as 28/4/38). 22/6/38 1 adult ♂ seen hunting through tall coconut groves.

The more open southern part of the island (salthans, tidal lagoon) is more favoured by ♀ and the ♂ favour the more forest areas nearer the central parts of the island. The signifi- cance shown of series of ♂ and then series of ♀ at certain periods does not mean any retiring of one sex for periods but merely that at such times I was working areas more favoured by the sex for some consecutive days.

Though the bird is found all over the island in reasonable numbers for the species. It is a solitary kind of bird never hunting in pairs or parties or flocking nor would it do so even if a plague of mice or some such appeared in an area, I believe it would
