Sunday September 25, 2016 Waterbird Society Charter - by Brian Patteson

After almost 70 nautical miles running out to the shelf break from Virginia for the last couple of weekends, it was a refreshing change to be back home in Hatteras, where the break is less than 25 miles out.  The short run here means we can run a lot of trips that would be impossible up north.  If we have to cut our cruising speed for a drier and more comfortable ride, it really doesn't matter much in Hatteras.  We might be a few minutes late getting out - not an hour or two.  We had a brisk north wind for the ride out, but it wasn't terribly rough, even when we reached the blue water, which was only about 15 miles from the inlet.  The first tubenose we saw was a Black-capped Petrel (photo below by Kate Sutherland) less than 16 miles out and we soon saw several more so we slowed down and started chumming.
We generally don't see any Black-capped Petrels until we get 25 or more miles out, so to see them on the shelf was exceptional.  But we had exceptional conditions.  The Gulf Stream had split and left a long tendril of pretty 85 degree water inshore.  As we worked offshore, we eventually passed through a band of cooler water - about 83 degrees Fahrenheit - before the water started warming again and getting rough about three miles past the shelf break.  We actually found more Black-capped Petrels - about 40 of them - shoreward of the break than we did offshore.  There were also a few dozen Cory's Shearwaters (photo by Kate Sutherland),
a couple of Great Shearwaters, and several Audubon's.  North wind is not very good for seeing Audubon's Shearwaters and tropical terns here, but we did have nice looks at an adult Sooty Tern and its begging youngster in an area of good seabird concentration.  There were very few storm-petrels to be found near the shelf break.  Perhaps there were more out in the deep, but it did not seem worth the beating to find out.  I was hoping for a little action at the north side of the eddy but we saw few birds there except for a handful of shearwaters.  There was a nice color change but it did not produce the hoped for phalaropes or Bridled Tern.  We did find a nice little group of Atlantic Spotted Dolphins there (photo by Kate Sutherland), however,
and because it was in less than 30 fathoms, we had just an 18 mile ride back to the inlet.  It was a great day to be out.  We had a lot of folks on the boat who had not been out on a Hatteras trip before and our star seabird, the Black-capped Petrel, put on a great show.  We ended up with almost 75 Black-caps for the day and some of the closest looks you ever get (photo by Kate Sutherland).
I would like to thank everyone from the Waterbird Society who came along and also those who helped arrange the trip but could not come.  Our charter trip followed the 40th annual meeting of the group!  Thanks also, of course, to Kate Sutherland for working the deck and making sure everything went as it should, all the while chumming, spotting birds, answering questions, and taking photos for this report!

A dark individual - note the extensive dark in the underwing.  This individual had some interesting dark spots on the some of the underwing feathers near the body (compare with the individual pictured below it).  This bird also has a very dark face and smudgy neck collar, not white.
In contrast to the bird above, this individual is a lighter bird.  Note how much white is in the underwing and also the white above the eye, nice black cap, and white collar.
The Atlantic Spotted Dolphins had a few young individuals with them too!
& the edge of the Gulf Stream on our way back in the afternoon - there was a nice temperature break and noticeable color change!

Sunday September 18, 2016 - Virginia Beach by Kate Sutherland

Saturday's weather was a little breezy from the east, so Brian postponed the trip a day and our 18 participants were at Dockside in Virginia Beach before 0400.  We were on our way by ten after 4 in the morning and passed Cape Henry into slight seas with light winds from the east.  The satellite image of the sea surface temperature showed some really nice looking water in and around Norfolk Canyon, so that is where we headed.
There were some clouds offshore when the sun came up a little before 0700 (photo by Kate Sutherland), hopefully indicating that there was some Gulf Stream influence out there.  On our 75 mile journey to the deeper water we passed some phalaropes flying by and had one nice group of six Red-neckeds sitting on the water with gorgeous reflections!  Two Loggerhead Turtles were also cooperative on our offshore trek, staying on the surface and checking us out as we photographed them (photo by Kate Sutherland).
As we approached the Norfolk Canyon, the water temperature began to increase and we passed some sargassum, typical of Gulf Stream waters, followed by some Portuguese Man o' Wars - the gorgeous stinging siphonophore that is characteristic of tropical and subtropical seas (photo by Dave Shoch).
The northern tip of the canyon welcomed us around 0930 and from there we headed southeast down its length.  We had good views of Cory's, Great, and Audubon's Shearwaters plus a few Wilson's Storm-Petrels.  A few Great Shearwaters flew right up the slick to the boat in their quest for food (photo by Dave Shoch), which they happily dove for behind us.
We passed the mouth of the canyon into deeper offshore waters over an hour later where we found some Pilot Whales, likely Short-finned, and a couple large flocks of Wilson's Storm-Petrels - unfortunately we were unable to turn up a White-faced Storm-Petrel.  We also did not find any Black-capped Petrels or jaegers like last weekend.  We were lucky to find another group of Risso's Dolphins, though, mixed in with some Pilot Whales, and they came right in to the bow of the boat to check us out!  It was an unexpected bonus to find this species out there two weeks in a row!  We picked up speed as we crossed the shelf break again in the afternoon and twenty minutes later a Bridled Tern flew in towards the boat, a really nice sighting!  While we were stopped to look at this bird, two more were spotted on a piece of wooden flotsam.  These two were an adult and juvenile (photo by Dave Shoch).
It was awesome to hear the young bird begging and watch the adult fly and pace from edge to edge of the float to get some distance from its offspring!  It was a long day offshore, but worth it to see what was out there and to get nice views of two Gulf Stream specialties, the Audubon's Shearwater and Bridled Tern.  The seas were calm so it was a gorgeous day out there.  We would like to thank everyone who joined us for this final Virginia trip of the summer, especially our group of seven birders from Finland who were traveling in the area this week.  A big thank you to our leaders, Ned Brinkley, Dave Shoch, and James Fox, they all did an excellent job spotting birds and marine life and helping people get on them!  Thank you also to Dave for letting me use some of his photos here!

Saturday September 10, 2016 - Virginia Beach by Brian Patteson

Yesterday we ran our first summer Virginia trip since 2006.  We left just after 0400 because it's a long way out to the shelf break there - 65 nautical miles from Cape Henry!  There was not much to see in the shelf waters except for a few flocks of phalaropes and a quick fly-by Long-tailed Jaeger.  A Leatherback Turtle was seen close to the boat, but briefly.
Out past the shelf break there was some activity - a few Cory's Shearwaters and Wilson's Storm-Petrels along with a couple of pods of Short-finned Pilot Whales.  Very soon after arriving we also found three Long-tailed Jaegers flying together and landing on the water for good views (photo by Kate Sutherland).
 The deeper water just offshore was almost birdless - just a few Wilson's Storm-Petrels and a distant Black-capped Petrel (photo by Kate Sutherland).
 We spent a while chumming past 500 fathoms with little to show for it, so I decided to head back inshore a couple of miles.  We had our best luck between 100 and 500 fathoms. There we found a scattering of Cory's Shearwaters and a single Great Shearwater.  Black-capped Petrel - which teased us earlier - showed well and we saw at least three more individuals which visited our slick.  Storm-petrels remained scarce and all that we saw were Wilson's.
The non-avian marine life was represented by several groups of Pilot Whales, some Ocean Sunfish, and a small group of Risso's Dolphins.  We also watched a White Marlin cruising at the surface of the water.  Increasing winds from the south and a forecast for that to continue kept us from getting as far north as the Norfolk Canyon and we started heading back to shore in the early afternoon.  Choppy seas and spray made it difficult to bird at cruising speed but we did get good looks at a couple of Loggerhead Turtles and we added Audubon's Shearwater to the day's list.  In some years we have found good numbers of Audubon's on these Virginia trips, but there was no Sargassum out there this time and that is important for them and for Bridled Tern, which we did not see.
It was a long day, but I feel like we made the best of a day with less than ideal sea conditions and sparse bird life.  It was good to see some marine life that is seldom found off Hatteras during the summer, such as Pilot Whales, Risso's Dolphins, and Sunfish.  Kate Sutherland, Ned Brinkley, Todd Day, and Ellison Orcutt did a superb job spotting, leading and chumming and I would like to thank all of our enthusiastic participants for making it possible to explore the waters off Virginia once again.  My first pelagic trips in 1986 were off Maryland and Virginia, so it's a homecoming of sorts.  Thanks also to Captain Kevin Seldon of Dockside Restaurant for providing dockage and parking for our trips here.
