Audubon's 23 May 2022 by Kate Sutherland

The morning began in the rain, our pre-departure briefing was given under an overhang but by the time it was over, the heaviest of the rain had moved on.  There were a few more showers as we headed offshore, but the seas were a bit calmer than the past three days so overall our ride out was quite nice.  A Pomarine Jaeger even came to check us out as we were running before moving off to the east.  There weren’t many birds around the shelf break so we kept running out to 100 fathoms (600 feet) and when we reached it we found a beautiful condition with light Gulf Stream current and scattered Sargassum.  The first bird of the day was a Black-capped Petrel, but then they were scarce until the latter part of the day (photo Kate Sutherland).
We started seeing Audubon’s Shearwaters right about there as well, on the water feeding in and around the Sargassum…likely eating some of the creatures we just viewed yesterday when we dipped some of this floating brown algae.  Little did we know they would be a feature today with over 100 tallied!  It was awesome to see so many of these small black and white shearwaters, they haven’t been around so far this spring so this was the first push we've seen up here (photo Kate Sutherland).
In the afternoon the wind shifted to the north and picked up to about 18 knots, with this the birding picked up as well.  Our slick’s customers grew in number and we were treated to the acrobatic flight of Black-cappeds, Atlantic Cory’s, Audubon’s, Wilson’s and Band-rumpeds as they came to check out the slick, then the boat, and wheeled away.  Just before reaching the shelf break we were treated to a new species for the Blitz: a gorgeous Sooty Shearwater came right up the slick and circled the boat before heading away (photo Kate Sutherland).
Tonight the winds will shift to the northeast and that is what’s forecast for tomorrow.  We’ll see if we can add some more species to the list then!

Thanks so much to everyone who joined us out there today!  And thank you to Peter Flood and Jason Denesevich for helping us lead the trip.  Today was Jason’s last trip with us, so another big thank you to him for his help over the past four days.

22 May 2022 by Kate Sutherland

The day began with more of the same wind we've been having, south west, blowing a little bit more than it was yesterday morning...maybe 16 or 17 mph.  So it was a little choppy on our ride to the shelf break.  However, we crossed two nice current edges with the second a bit harder than the first with some smoother water offshore of it.  This was where we found our only Audubon's Shearwaters of the day, plus one flyby Red-necked Phalarope.  It took some time for the Wilson's Storm-Petrels to gather in the slick and the first larger tubenose of the morning was a nice Atlantic Cory's Shearwater! (photo Peter Flood) 
We had some excellent views of them today.  Not long after that we began to see some Black-capped Petrels.  They kept their distance today except for when they were expressing displeasure (yes, I know, anthropomorphizing!) at seeing Pomarine Jaegers in the slick! (photo Peter Flood) 
We had our first Pom in the 0930 period and then had two more visit us, the third following us for close to three hours.  The first Band-rumped Storm-Petrel appeared just after 1000 and we had excellent views of them for the rest of the day in the slick! (photo Kate Sutherland) 
All of the individuals except for maybe one, were molting, indicating the winter breeding population, presumably "Grant's" type.  At the end of the day, clouds rolled in and the wind picked up to about 20 to 23 mph and became more west south west.  The slick came alive and we had our Pomarine Jaeger (photo Kate Sutherland),
Black-cappeds, a couple of Cory's types, Wilson's, and Band-rumpeds all putting on a good show as we approached the shelf break.  Pomarine Jaeger was a new species for the Blitz and it was good to see a few out there today.  Tomorrow the wind will be a bit different, so we'll see how that translates offshore - west - maybe will blow the birds out?  Or perhaps carry our scent and lure them to us - regardless, we'll be out there to see.

Thanks so much to everyone who joined us today!  And thanks to our leaders, Peter Flood and Jason Denesevich, for helping Brian and I lead the trip.

Day 2....21 May 2022 by Kate Sutherland

Well, some days we just find the usual suspects.  And that's more likely when the winds are the same for a few days in a row.  Today was day three of a south wester and while it was a bit calmer out there today than it was yesterday, the birds were not as cooperative.  We did have some attentive Black-capped Petrels which for me pretty much makes the day!  Here is one I photographed today:

Audubon's Shearwaters were out there in the Sargassum, which was nicely lined up in the Gulf Stream offshore.  They tend to be associated with this floating brown algae and will feed on small fishes and other creatures that utilize the Sargassum for cover.  Unfortunately they didn't show well, but perhaps tomorrow with some calmer conditions will be better!  We did have some nice views of Atlantic Cory's Shearwaters passing by (photo by Peter Flood) 
and the Wilson's Storm-Petrels were our faithful followers for our time beyond the shelf break!  

As we motored back inshore we found some nice patches of Sargassum and took a few minutes to dip some and see what we could find with it!  We were lucky to find at least three very small Sargassum Pipefish, a few Sargassum Swimming Crabs, and some small shrimp in the genus Leander.  Participant Chris Thomas took a few videos that you can find at the bottom of the post! *to be added in the next few days!

Thanks to everyone who joined us out there and a big thank you to Peter Flood and Jason Denesevich for helping Brian and I lead the trip today!

The Beginning! 20 May 2022 by Kate Sutherland

 It was still pretty breezy as we headed offshore this morning for our first day of the Spring Blitz!  Skies were partly cloudy and the wind was blowing 15 to 20 miles per hour from the west southwest.  The ride to the Gulf Stream was a bit wet, but once we found the current edge - we could see the slick along the edge of the swift current with calmer water beyond.  When the wind and current are together, the seas are much calmer.  This gave us a nice condition to begin our fish oil slick and once we crossed the shelf break and saw our first Black-capped Petrel we put out more chum.  Surprisingly the Black-cappeds were hungry and they came in well with close to 40 individuals seen in the first hour! (feeding Black-capped by Kate Sutherland)
We had more Audubon's than we've seen so far this spring and a few were very obliging next to the boat.  Atlantic Cory's were seen as well and we had our first Sooty Shearwater of the year as we approached the shelf in the afternoon.  Wilson's Storm-Petrels were slow to gather, but we had a nice flock midday with Leach's and Band-rumped Storm-Petrels both making appearances! (Leach's photo by Kate Sutherland)  
It took awhile, but I think everyone got to see both species fairly well!  The list was rounded out by an Arctic Tern that came to check us out in the 1130 period.

Thanks to everyone who joined us out there today, we had a salty crew!  And thank you also to Peter Flood and Jason Denesevich for helping us to lead the trip.  Next report tomorrow!

Mid-May is Magical! by Kate Sutherland

Mid-May can be a great time for seabirds offshore from Hatteras, however the weather can be a bit unpredictable.  So as we approached our Friday May 13th trip date we were just finishing with a nor'easter that sat offshore here and wreaked a bit of havoc on the highway to Hatteras village...luckily the winds and seas subsided early Thursday morning and the highway was open for business by midday.  A large weather system like that can make for some interesting birding in the days that follow, if we can get out there.  We were lucky on Friday and despite dense fog on the way to the ocean, we made it offshore and conditions were excellent for birding.  As were the conditions the following day when we had some down current (an eddy in the Gulf Stream that is moving the opposite direction from the usual north easterly flow) and easterly wind.  By Sunday conditions were much calmer and skies clear - each day was unique.  For this reason we typically recommend taking more that one trip with us when you're here, availability permitting!

The definite star of the weekend was the European Storm-Petrel we had Saturday morning less than an hour after crossing the shelf break!  This bird was spotted by myself and Jamie Adams simultaneously as it darted across the stern flashing its diagnostic white bar under the wings!!  After some pandemonium as we worked through the excitement of having a look at this species that hasn't been seen offshore here since June 1, 2019, we got people situated and did our best to call out the flight direction and identification criteria as it moved in a flock of Wilson's Storm-Petrels.  Hopefully most everyone saw it during its brief visit in challenging seas - by the time I took a minute to photograph it, it was not close and also flying away...but even so, this image with the dark upper wing and thin pale margin to the secondary coverts in addition to the short legs, is enough (Kate Sutherland) to identify it!
Later that same day we had a super cooperative Fea's Petrel come to investigate the slick after being glimpsed at a distance for some time.  This is the third sighting of this species for the spring, and it looked likely to be a Deserta's Petrel, one of the species in the Fea's Petrel complex (the others being Cape Verde Petrel and Zino's Petrel) and the one we think is most likely seen offshore from Hatteras.  We had some rain on Saturday, but that didn't slow or deter this bird from coming to check out the slick!  There were excellent views for all aboard (Kate Sutherland).
Friday we were treated to a gorgeous, adult White-tailed Tropicbird who was also super cooperative and interested in our chum!  It came to the boat and flew around multiple times at close range, swooping down to investigate us in the stern.  Looking over my photos as we headed back to the dock that afternoon I realized the bird had a band on its left leg!  A quick message to Jeremy Maderios, Bermuda's senior terrestrial conservation officer and Keeper of Cahows and Longtails there, confirmed that he does band chicks fledged from Bermuda on the left leg to track that they are a known age / location individual.  This bird was banded by him as a chick and is the first we have seen offshore here with a band!  Since 2006 Jeremy has banded about 1,700 White-tailed Tropicbird (Bermuda Longtail) chicks.  (top photo Bob Fogg, lower showing band by Kate Sutherland)
To top off the three day set we had a Brown Booby on Sunday's trip that flew by, showing well, but not coming in very close.  (Bob Fogg)
In addition to these encounters we had excellent luck with our Gulf Stream specialty the Black-capped Petrel seeing multiple individuals each trip and all days had some close passes.  While we didn't find many, we did have Audubon's Shearwaters on each trip, and another species we hope to find in the warm water, Band-rumped Storm-Petrel, made an appearance each day as well (Kate Sutherland). 
Atlantic Cory's Shearwaters are starting to show up, and the storm-petrels were just incredible with hundreds of Wilson's Storm-Petrels following us each day and multiple Leach's Storm-Petrels seen with them.  Pomarine Jaegers loyally stayed with us eating bits of fish as we motored, Parasitic Jaegers were seen best on Friday but we had at least one each day, and a Long-tailed made a pass on Saturday's trip.  Arctic Terns showed well on all three trips coming in to the boat and feeding for some time on chum before moving on.  A highlight for us was seeing both species of phalarope, sometimes together, on each trip!  There are still a few Red Phalaropes around and we had excellent views of this larger species on the water each day with the more numerous Red-necked Phalaropes also showing well!  Overall it was a great time out there even with some larger seas, fog, and rain making birding a challenge!    

Thanks so much to everyone who joined us making these mid-May trips possible!  A huge thank you also to Bob Fogg for joining us as a leader on all three trips and sharing his photos with us, Matthew Withrow who also helped on all three days, Matt Jansen who joined us Saturday, and Sarah Toner who joined us Sunday.  We couldn't do it without them!  The Spring Blitz begins on Friday...these reports will be brief, but we'll keep you posted!
