P. De Benedictis 1964 25 16 Jan. On board "Golden Bear" off Southern Myrtle, got up about 6:30. A warm, humid, sunny day, scattered, low fluffy white cumulus clouds + little wind. Looks like everyone will get burned today! About 6:45 spotted 3 of the brown colored boobies flying along side the boat stayed with the boat for about 10 minutes. Uniform, princess - a little darker than the second one. About 7 or nine adult Red-billed Tropic birds showed up over the boat and stayed for a while - about 5 minutes. later a bird with a white step and all white - primaries appeared. No noose mark but black about thighs. Feet & legs black, bill white. The tailed bird cackled a few times, a short and explosive, rough, high-pitched "nyock!" Also saw a small dark petrel, square or fork tailed, which flew with a rapid low low wingbeat and much less gliding; stayed off the bow for several minutes. Ate at 7:45 about 9:30 saw 3 boobies far out and 3 close in. The rocky birds dropped their feet showing the red-socks, so they are Red-footed, all brown (black-tailed) phase. About minute later we saw 3 (2 act. + the white bird) Tropic birds together. The white bird calls a rough, insolent high pitched "urrnock" a little lower than the adults. Stayed until about 7:15 although the adults disappeared sooner. About 8:15 found a Dominique Jaeger, immature, flying fairly high along the boat, and 2 more Red- footed Boobies, brown phase. About 18:20 - 8:25. About 8:30 2 adult Red-billed Tropic birds appeared and
