15 Jan on board the Golden Bear off central Mexico.
3 falcs. Afterwards we gratefully went up; few birds,
about boat a squall was evident. We first saw
a numm. Blue-faced Booby, like yesterday, and later
another frigate bird About 11:00 it became obvious
we were going to go through a squall, but the birds
became quite varied. Saw 1 or 2 undistinguishable
Boobs and 3 Parasites & horn-tailed Jacers,
about (1). about 15 minutes later we went
through a big group of birds, of which I managed
to miss most. About 15 Frigate birds, 4"Sooty
Terns together. Then we flushed a Wedge-tailed
Shearwater from the water. It got off with a
stiff wing beat unlike the other Buffins we have
seen. Brown phase with a conspicuous pale area
on the greater secondary coverts; tail shaped
with a booby - < > and easy to see. Most
of the birds were right along the curve where
the wind cooled and shifted as we went in to
its squall and so birds actually in the storm
area. Went for lunch when it began to rain (12:30)
and got back a little after noon. about 12:10-12:15 a ?
Frigate bird circled the boat, inflating its throat
pouch occasionally. Notting the secondary &
inner primaries & 1 tail feathers. Conspicuous tail
shaking in flight, and the un-inflated throat
pouch is easy to see in silhouette.
