It was good to be back out on the big boat with a good number of participants on two consecutive trips. The weather was quite different each day. On Friday we had light winds and slight seas for most of the day and on Saturday, it was pretty testy in the hot fast water for the six hours were spent there. Shearwaters were seen in good numbers each day and recent trends continued. We had modest numbers of Cory’s Shearwaters (photo by Kate Sutherland, individual pictured is a good candidate for Scopoli's)
and good numbers of Great and Audubon’s
Shearwaters. On Friday morning there was
a good flight of shearwaters as we headed out over the continental shelf, but
there were also many birds sitting by mid morning. On Saturday, there were more birds moving
over a very broad front for most of the morning. Storm-petrels were very scarce on Friday and
we had our first miss on Band-rumped since May.
We did better with Wilson’s on Saturday, but it took a while to chum up
a few Band-rumps. Black-capped Petrels
were very scarce on Friday, but showed up well with the wind on Saturday (photo by Kate Sutherland).
It was a great day for Black-caps and we had
several feeding close in the chum during the early afternoon. On Friday we had a nice flock of Bridled
Terns come in and feed in the slick.
That’s right- we chummed up the terns (photo by Kate Sutherland).
Sooty Terns were notably absent after being around the last couple of
weekends. We did not find any feeding
flocks of seabirds over tuna in the slope waters this weekend despite a bit of
looking. Friday was a good day for
phalaropes and we saw a few flocks, but they were all on the move. I was hoping for some jaegers with the cold
front, but our only good look was a Pomarine chasing Audubon’s Shearwaters on Friday. Mid to late August has
historically been a good time to see Trindade Petrels and tropicbirds, but they
have not been around much lately. What
have been around though are boobies and we saw two nice ones on Friday: first a flyby Brown spotted by Kate, and then a second
summer Masked Booby I picked out of a shearwater flock (photo with Cory's by Kate Sutherland).
The Brown was our third for the season and it
was our second Masked Booby for the year.
I would like to thank Kate Sutherland for doing her usual excellent job
leading and this week's guest leaders- Scott Winton (check out his blog post about the trips here) and Natalia Ocampo Penuela-
for doing an outstanding job as well.
They were particularly diligent in reporting every bird they saw for the
day’s count. We are running another trip
from Hatteras on Saturday, August 29 and
space is available. We also have space
on a small boat trip on Sept. 5. After
that, we don’t have any open trips scheduled for a while, but we are open for
charters. September is a good month for
seabirds here- usually all month long. Thank you to everyone who joined us for these trips!
