Lehner, P. 1965 Feb. 6 ran mouse grid; several Sooties over the island at 0900 with several thousand off shore; Gray- backed Tern eggs total: Islet 14 total, 2 new Pier 9 total, 2 new reset mouse traps about 2200, between the frequent rain squalls which continued all night. Feb. 7 ran mouse grid traps; a few Sooties (20-30) over the island at 0930; checked Gray-backed Tern eggs: Pier 11 total, 3 new, 1 destroyed Islet 11 total, 3 destroyed Great Frigate bird eggs now appear to be down to about 4 on the islet; Chief Rossi went along and we took pictures of the Gray-backed Terns and Great Frigate birds; the Red-footed Boobies have been spending more and more time in the usual nesting area - it would be safe to say that nest building has begun, but no eggs have yet been layed; set the mouse traps in the late P.M.; Red-tailed Tropicbird chick on SW end of causeway shows pin feathers coming in on upper back.
