Clapp, Roger 1964 March 14--Landed on Jarvis about 9 and set up camp in the building left by the IGY. Cats are plentiful and relatively "tame". One of their major retreats is the building. When we cleaned it out, we found many birds feathers indicating their diet. Among those feathers readily identifiable were a number of sets of wings of Sooty Tern. A young booby was found (sp.) and in later explorations under the house, we found the carcass of a young Red-tailed Tropicbird. In the afternoon Fred spent much time shooting and retrieving cats under the house. In the evening he spent most of his time chasing cats around the island getting some thirty in all (from many of which blood samples were taken. Stomachs examined were found to contain feathers. After setting up camp we ran the usual survey of the island. Boobies are very abundant (perhaps 750 Brown Booby 2500 Red-footes and 5500- 6000 Masked Boobies. The majority of Masked Boobies are pre-breeding (In pairs and territorial although few eggs have been laid.). The Red-feet are slightly more advanced in their cycle, although most ests are empty. Many Red-foot nests on the island are placed flat on the ground. Others are placed low (8 - 12") in small Sida bushes; with not even a "platform" of sticks under their nests. (Very possibly it indicates that Red-feet have colonized this island "recently"). Several nests (but by far the minority) are placed on elevated areas such as barrels, or perhaps the framework of the weather station left by the IGY. All boobies on the island (except Brown Boobies which are apparently "congenitally nervous") are much tamer than on other islands.
