Amerson, B. 1963 C.G. LORAN Station, Sand I., Johnston Is. Atoll (2 under-Scaevola and 1 under fuel tank ). Banded all 3 young and 2 adults - also 1 nomesting adult. Before starting banding program, photos (color and B and W) were made of the island, its plants and birds. During the afternoon Boobies were banded and nest data taken. Nineteen Brown Boobies were banded (8 chicks, 5 immatures, and 8 adults). Two of the adults were oneegs. The adults from other nests became jumpy and will have to be banded later. Two banded Brown Boobies were recovered: (697--69607 on 2 eggs) and 697-69606- with lg. chick. These are probably birds Ashmole banded when he was here. Five Red- footed Boobies are nesting. We were able to band 3 adults and 2 1/2 grown chicks. Three of the nests contain eggs. Another Red-tailed Tropicbird nest (with large chicks) was found under a concrete slab on the east end. The chick was banded. During the afternoon I sent a message to D.T.C. giving estimates of bird species numbers as requested by them. This was to have been made by July 5 but we arrived of course on the 7th. The Derlese Funnel was set up in a work area provided in the pump house and a litter sample from the Sooty Tern colony was run. Wilz opened 400 no. 5 bands for use tonight. After supper 12 mouse traps were set to sample the small mammals. Only Mus musculus is expected. Those were set on the east end of the island around the garbage dump. After dark (after 9 pm) we banded 400 Sooty Terns (all adults).
