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
