Johnston, D. W. 1964 13 16 Apr Wake Island by droughts and typhoons; also Wake was nearly totally devastated by military activity between 1941 and 1945. Where the salinity is too high, Pemphis and Sesuvium form the normal vegetation. Tournefortia woodland is a fairly stable stage: undisturbed it may give rise to Pisonia or Pisonia-Cordia forest. Tournefortia colonizes successfully bare sand and gravel, so it may immediately succeed itself if destroyed by storms. Some plants: sand spurs, Bermuda endcrab grass; Pisonia (Puke-tree with greenish flowers); Sesuvium portulacastrum (seaside purslane); dwarf poinsettia; Pemphis acidula (tree or shrub with white flower); 17 Apr In morning we went out to Kuku Point. Partly cloudy and intermittent rain later on until early afternoon. Went into Tournefortia woodland looking for Red-footed Booby and Great Frigate-bird nests. There were 15 of the booby nests in 6-8 trees, some trees containing as many as 3 nests. Each nest was a simple platform of sticks which you could see through from below. Evidently each occupied nest contained an egg--adults were sitting tightly. In one nest there was a large, white downy young--differed from Brown Booby young by having blackish bill. On adult instead of being essentially blackand white, was of the dusty plumaged color phase. These boobies generally sat closer than did the frigate-birds but were less prone to return once they had flown off. The adult came in and regurgitated a fish for the yng. booby. All nine of the frigate-bird nests were in 2 trees, 10-12 feet off the ground. These trees were also occupied by st
