Amerman, Kenneth 1964 Some Scaevola patches extend into the Ipomea almost to the lower edge of the vegetation on the east side. Two groves of palms, one at the northwest corner and the other at the southeast corner of the lagoon and one large Casuarina constitute the only land marks. Scaevola forms a secondary line behind the rim on the west side, diminishing toward the south. On the south end the Scaevola is very dense and occupies a broad area. A few Red-footed Boobies and one small colony of Browns are found in the outer rim of Scaevola on the west side. Tropicbirds nest in small concentrations (5-6) under higher, larger clumps on the west and down sides, and in larger groups (20+) under very large clumps on the east side. Most of the Frigates are scattered through the western Scaevola rim. Red-footed Boobies increase. Frigates decrease in Scaevola on the south and east. Masked Boobies found in grass (scattered individuals and pairs from Scaevola to Ipomea) and some concentrations in open areas in grass, around lagoon and on east beach. Wedgetails very numerous in grass, less so in Ipomea, fewest (breeding) on open beaches but glarge clubs scattered over beaches on north, east and south. Christmas Islands - resting under outer Scaevola rim on west; immatures just at inner edge; some in Ipomea on west side, some under rocks on west side, some under rocks on west and north beaches. Bonin Island Petrel most common in dense Eragrostis (no Sooty Terns), many at and under edge of outer Scaevola, few in Open grass among
