11-4-63 Up today to observe again in the Radar tower. After banding a plover, got aloft at 0800, and after lunch again at 1310. In general there was little activity today except for frigates which were enjoying soaring on the strength of a very steady 8 - 18 Kt. SE breeze that was being deflected by the East beach. A few Red-foot joined this activity. But today the big news was the first big return of Black-feet and the first Laysan. From the Radar tower I saw five land, seven in air (Black-feet). Other birds seemed to be just sitting, preen- ing and regenerating feathers. At 1600 we set th rat traps again and just before dinner repaired and reset the mist nets to new locations in the hopes of improving our shorebird catch. While up in the tower I got a good long look at the monkey who is doing fine. He was apparently feeding on the fruits of the Seaveola bushes and seemed in good pelage. In the evening we went banding goonays and got over 40 and one Laysan albatross as well as several Frigates and 10 Red-feet. I weighed one Red-foot Adult ( 1435 grams ) and one Black-foot ( 3542 ± 20 grams ). The Black-feet are roosting deep in the cuts of the seaveola, often as far back as the scales, and today I watched two birds billing, but the display went no further. Tonight I noted for the first time some birds with seemingly very thing lines of white on the forehead ( ?'s ? ), and perhaps things will pick up in this area. I have also seen several Black-feet sitting beside well constructed scrapes: In one case the scrape was made in the morning as I checked the bird before going on the radar tower and then before lunch. Most of the albatross arrived here today between 1500 and 1900. Concerning the boobys in the antenna fields: Moulting in the Masked and Browns has now become very pronounced. All adults of the Masked except the one pair with eggs are moulting heavily. One Red-foot caught tonight in immature plumage ( apparently in its first complete moult was found to be greyish-white where as a Juvenal he was grey, and others caught in another stage where the scapulars and some of the back feathers and upper-wing coverts retain the grey suggest that three years are required before the birds attain a complete adult plumage. However, only specimens of banded, known age birds, birds will give us that in- formation. Wirtz wants the typewriter.
