Amerson, B. 1963 C.G. LORAN Station, Sand I., Johnston I. Atoll rock just off shore. About 25 Gray-back Terns were found but not nesting. Approx. 50 Frigate Birds (very few immatures) were roosting. Four Brown Boobies had nests (3 Locals and 1 nestling). What appeared to be a Masked Booby was seen but it had a few black feathers on it's back. It did not have red feet. Several hundred Common Noddies were present with some having eggs, chicks and locals. An old concrete bunker is in the center of the spit and Wedge-tailed Shearwater were nesting down inside under the edges. We waded back to the main island and I obtained a litter sample from Common Noddy nests. This was placed in the Berlese Funnel upon our return to the C. G. Barracks. Ken Wilz opened 4:00 no. 3 bonds during the early part of the afternoon four use on the immature Sooty Terns. After dark (9 pm.) we put these on immatures in the same area as the adults last night. We were through by 10:30. July 10, 1963 This morning Ken pointed indentication numbers on the stakes and put them aside today. I wrote a letter to Dr. Humphrey, which took most of the morning . Ken made a listing of banded Frigates and Boobies so we could number nests and record pairs. After lunch we placed stakes at the proper nests. Five more Brown Boobies were banded, 2 more Red-footed Boobies, 4 more Frigates and 2 more Red Tailed Tropic- birds.
