of its time being spent in and about palms (10 per cent in bushes and shrubs growing between palms and near trees) it does not roost for the night in palms. At dusk one may observe birds in purely coconut and grass areas making all hast for the nearest large dense tree or patch of tall scrub, often at considerable distances. It is an early and late caller and leaves in the first grey dawn for areas again well within purely coconut cultivation. I made many efforts to find birds in palms at night even in low dense coconuts a few years old but all showed negative results. The only reasons I could see for this was that palms did not offer sufficient cover from natural enemies, owls and snakes to a small degree. By the excited behaviour of this bird when they see a rat I believe these also possibly are natural enemies, certainly to eggs and young but possibly also to adults at night. Rats frequent the palm tops at night, not to feed on green nuts as do ships' rats, but to feed on flowers and very young nuts and obtain water in some dry areas. Merely their presence would be frightening to birds. Movement:- It is noticeable that this species also shows a tidelike movement in the other direction (i.e., from coconuts into forest) but to a very sharp boundary line only a short dis- tance within forest areas, but within such areas numbers increase enormously for a day or two. These waves did not coincide with waves of other birds, though occasionally they did so. They definitely did not coincide with Myzomelas outwards movements in a single instance. When returning across the lagoon from one of the out- lying islands on the western reef on which we had to land and shelter from bad weather, in a small 15 ft. sailing dinghy, I saw an example of the exploring and inquisitive and spreading
