Oregon Inlet Departures Summer 2023 - Kate Sutherland

Ten years have passed since we last ran trips from Oregon Inlet, we had some issues with weather that caused us to head back to Hatteras to finish the set that year. We're very lucky to have two ports of departure we can use to get out to deeper waters offshore from Hatteras Island! While our trips in late summer from Hatteras are productive, the water gets really warm, and we have been itching to get back to the north where there is a nice interaction of the Gulf Stream with a cooler water current coming down from the north. The interaction of the cooler waters of the Labrador or Virginia Current meet the warm, sometimes hot, waters of the Gulf Stream and this causes nutrients carried in that cooler water to fall out creating what is called a deposition zone - and areas of high productivity. While the shelf break is a bit farther for us to the north, these temperature breaks coupled with the upwelling from the canyon areas can be a really interesting place in the late summer. In the image below you can see the inlets labelled and also the proximity to the shelf break which is the closest on the east coast!
This image from NASA shows how this warm water current travels along the southeastern US before being deflected to the northeast by the cooler current flowing from the north. 
The ecosystem created by the interaction of these water masses is incredibly dynamic and one of the reasons we run these seabirding trips from Hatteras.

Last year I began working with Duke Marine Lab doing research offshore from Oregon Inlet, covering some of these canyon areas and The Point to the east of Hatteras Island. I was pleasantly surprised how much life was up there compared to what we had been seeing south of Cape Hatteras over the past few years when the Gulf Stream comes up onto the shelf. Of note from 2022 were good numbers of both Leach's and Band-rumped Storm-Petrels plus excellent numbers of Black-capped Petrels and even a few Fea's / Deserta's Petrels and White-tailed Tropicbirds! Years ago we also ran our White-faced Storm-Petrel search trips up here, it is the best place for us to look for these charismatic little kangaroo birds. These images below are ones I captured on a trip from Hatteras in 2019, the second shows it with a Band-rumped Storm-Petrel.
East of Oregon Inlet can be a good place to see Black-capped Petrels, of course, and trips up here have also found Bermuda Petrels, Fea's / Deserta's Petrels, and Trindade Petrels. Our usual expectations for the summer should also be found here with good numbers of Cory's, Scopoli's, Great, and Audubon's Shearwaters plus some tropical terns! I just saw at least one Sooty Tern last week up there. Masked Booby is another possibility and hopefully we can turn up some jaegers and skuas as well. Tropicbirds are definitely in this area in the summer so there is the possibility to see White-tailed Tropicbirds and you never know...a Red-billed could show up as well. 

Non-avian highlights in this area include the deep diving Cuvier's Beaked Whales, or Goosebeaks as we like to call them. The males of this species have a diagnostic whitish coloration to their heads making them easy to spot at a distance and sometimes they can put on quite a show pushing out of the water before diving deeply to feed in the canyons just offshore of the shelf for over an hour! Here are a few images I captured in 2018, you can see the heavy scaring on the back which is different from the Gervais' Beaked Whales we see more often south of Hatteras (they scar dark!). 
It is always exciting to encounter them. We also could see Short-finned Pilot Whales, Offshore Bottlenose, Atlantic Spotted, and Risso's Dolphins. The temperature breaks can be good places to see Giant Manta Rays...you just never know what you'll find offshore! This is true where ever you choose to take a trip to the deep, but we hope you'll join us this summer to see what we can discover east of Oregon Inlet and Hatteras Island!

This summer we have ten departures from Oregon Inlet (August 22 to 31 daily) in addition to our regular summer trips from Hatteras (August 4, 5, 18, 19). Pricing is the same for all trips - $210 for one space with a discount offered if you join multiple trips and pay by check or money order! More information about the trips can be found on our website: https://patteson.com/ under Gulf Stream Trips and you can register for a trip by using the form on the Sign Up page. If you have questions of want to check availability please email me, Kate Sutherland, at cahow1101@gmail.com. I hope to see some of you aboard next month!

Risso's Dolphins in the Blue Desert 10 June 2023

Another day with high pressure and a high ceiling! Always tough conditions for seabirding in the Gulf Stream here offshore from Hatteras. We had light winds most of the day and sunny skies. Birds were slow to come to the slick but we finally recruited some Wilson's Storm-Petrels plus we had some Black-capped Petrels come check us out too. Band-rumpeds were not as cooperative as yesterday but we did have at least three individuals make some close passes. One highlight was participant Doug Hanna finding a small pod of Risso's Dolphins out in the deep! This is the first time we have seen them this spring and they were super cooperative giving us some great views. 

The trip report can be found here: 


And a big thank you to Ed Corey and Mario Balitbit for helping us lead the trip today! ~Kate Sutherland

A few images of the Risso's Dolphins I took today. Older individuals are paler than younger ones, and this species has tall, falcate dorsal fins. We had some young and old today! As they age they also have more scaring from other individuals and also from prey species like squid.

This image is actually several moments later than the one above! Interesting to see how some of these younger animals stayed close together.
It was also a good day for flyingfish...!

A Day in the Blue Desert - 9 June 2023

If you have been offshore with us in the past, you have heard me likely explaining the habitat in the Gulf Stream offshore from Hatteras! This water is hot and has just pockets of life with mostly a vast expanse of blue water, blue because it is lacking phytoplankton and other creatures to intercept the light as it moves down into the depths. So it is like a desert - a vast, blue desert. Today we felt that as we searched the horizon for birds as we moved out past the shelf break. Like yesterday we kept searching for some concentrations of birds in the morning and ended up in over 7,800 feet of water!! Our patience and watchful eyes paid off and we ended up with a nice collection of birds and some really incredible views of the usual visitors. 

Check out the trip report here:
And remember to click on the photos tab to see images from the day!

Thanks to everyone who joined us and thank you as well to Ed Corey and Jesse Anderson, some of our faithful NC leaders, for helping Brian and me lead the trip today!

Here are a few images I captured today

Not every day you can capture a Band-rumped with a diving Great Shearwater!
A couple more images of one of the molting Band-rumpeds we had out there near the end of the day.
A Black-capped Petrel, likely a darker individual.
Some of the Atlantic Cory's we're seeing have super worn outer primaries! You can see these look very blunt due to the wear.
Our faithful Wilson's dancing for us as they fed in the slick!

Hungry Birds - 8 June 2023

We were lucky that the rain moved through before we had to be at the dock this morning, and that it wasn't waiting just offshore for us...but it did push some birds farther offshore. Luckily we made it out there in some nice conditions, all the way out the 1,300 fathoms (7,800 feet)! And we did pick up some birds once we started chumming. While we didn't find anything unexpected we did have really great views of both forms of Black-capped Petrel, excellent views of both Cory's and Scopoli's Shearwaters, and really cooperative Band-rumped Storm-Petrels both molting (presumed Grant's type) and not molting. 

You can find the trip report for the day here: 
and remember to click on the tab for photos to see images from myself and leader Jesse Anderson!

Thanks so much to everyone who joined us out there today and to Jesse for helping Brian and me lead the trip. ~Kate Sutherland

It was really cool to see some of our usual suspects diving for chum out there today! Here are a couple - Great Shearwater (top two) and Wilson's Storm-Petrel (bottom two), from my images today.
Here are a couple of the non molting Band-rumped - top two over a flock of Wilson's feeding and bottom one a dorsal view.
We also saw this gorgeous (but to be admired from afar...) Portuguese Man of War out there today!

White-tailed Tropicbird and Trindade Petrel!! 3 June 2023

The final day of our Spring Blitz was another good one! We've been really lucky on the days we've been able to make it offshore, if only the weather had been a bit more cooperative...but we'll take 8 out of 15! More fog and northerly wind, but not quite as much current as previous days so it was actually quite nice out there. We had nicer Gulf Stream water too and the skies cleared up once we were offshore of the shelf. Within an hour we had really nice views of both a White-tailed Tropicbird and a dark morph Trindade Petrel - WOW! Shearwaters are also here so we had great views of Cory's, Scopoli's, Great, Sooty, and Audubon's in the slick. And Band-rumped Storm-Petrels have also begun to show well so everyone on board practiced their identification skills in the stern and hopefully had them down by the end!

The trip report from eBird can be found here - reminder to click the tab for photos to see those taken by us.


Thank you so much to Steve Howell and Liam Waters for contributing photos and for helping Brian and me lead the trip today! - Kate Sutherland

The White-tailed Tropicbird stayed with us for awhile giving everyone ample opportunity to photograph it with camera or even cell phones!! (K. Sutherland)
Liam spotted this Trindade Petrel coming in on the bow while we were on a slick - here is one of the images he captured! (Liam Waters)
He also got a couple of photos of the Scopoli's Shearwater that came in at the same time as the tropicbird - here are ventral and dorsal views - note the extensive white in the under primaries! (Liam Waters)
A couple of presumed Grant's type Band-rumped Storm-Petrels (Liam Waters) each with at least a couple of old primaries.
