A pair of boobies off Hatteras


This weekend was Natalia's first time officially spotting on a pelagic.  While she performed admirably for a couple days out in the Gulf Stream aboard the Stormy Petrel II, a sexier pair of boobies ended up stealing the show. 

You never know what to expect when rolling the dice on a pelagic trip, or hell, in birding anywhere, but on Friday's trip we encountered something unprecedented.  We first spotted a distant sulid--a young Brown Booby, which uncooperatively picked up and flew away from the boat. Not 15 minutes later as we were creeping up on a flock of sitting shearwaters I heard Brian's voice over the radio urging us to look at the "big white bird in the middle."

This booby was far more friendly than its Brown cousin and seemed content to preen with its shearwater friends while we ogled from close range.

It looked like it was molting into its first set of adult or near-adult feathers, giving it a bit of a mud-spattered look.

The mud-spattered thoughts were too offensive and off it flew.

With two boobies around and the hot, still weather, it was feeling like the Caribbean out there, so not surprising that Bridled Terns also put in a good showing.

Otherwise, the weekend provided the usual summer pelagic species found off Hatteras.

A north wind turned the ocean into a roller coaster on Saturday which brought a lot more Black-capped Petrels in close to the boat.

I rate myself a pretty lousy sea bird photographer and this pic captures my lack of skill, while at the same time the Black-capped Petrel essence.  They're so fast it's all I can do to keep one in frame!

The Saturday trip also offered some good looks at Band-rumped Storm-Petrel, which we missed entirely on Friday.

Thanks to Brian Patteson and Kate Sutherland for organizing the trips and making it a fun weekend.

Spotting for Bee Hives on the Gulf Stream

 I gaze over Gulf Stream waters from the bow of the Stormy Petrel II and see nothing but endless blue swells.  In the calm there are no birds nor creatures of any type to be seen.

As a spotter charged with finding birds for paying customers these famines can seem interminable.  There's nothing to do but keep scanning the horizons hoping to spot a distant feast.

Brian Patteson calls such bird swarms "Bee Hives."  Schools of tuna force baitfish to the surface, which attract ravenous flocks of shearwaters.  The arcing and swirling tubenoses on a distant horizon recall bees at a hive.

With one spotted, Brian slams the boat into gear and we race toward the action, stumbling upon straggling, loafing, satiated shearwaters that allow close approach.

Cory's Shearwater

Over the two trips last weekend we found three "bee hives" of shearwaters some 35 miles from shore, and in one we found a ferocious hive queen.

The South Polar Skua is a kleptoparasite, making its living by stealing fish from seabirds. Brian said he has even seen them kill shearwaters.

While we didn't witness a murder at sea, the bulky pirate was causing utter pandemonium among the flocks and committed countless larcenies.

Check out this video of the action.


The skua was my favorite bird of the weekend (now I just need to find a Brown Skua, and I'll have seen all the world's Stercorariidae), but there were many other highlights.

On Saturday's trip we had, per Brian Patteson, one of the top 10 Leach's Storm-Petrel trips of all time.

Leach's Storm-Petrel
Yeah, storm-petrels are tough to photograph.  They just don't hold still.  But for those with the proper combination of equipment, skill, and patience, this was an excellent trip for storm-petrel photo ops.

My Band-rumped Storm-Petrel photos are even worse than the Leach's shot above, but I got some decent Wilson's Storm-Petrel captures.

Check out those long legs!

A fortuitous find was a young Bridled Tern resting on a float on Saturday.

We saw one or two Bridleds on Sunday as well, plus a Sooty Tern.  These tropical pelagic terns are not very common off of Hatteras until August.

Finally, the smooth ocean made for some excellent marine mammal spotting conditions.  We had Bottlenose Dolphins riding the bow, several good sightings of Gervais' Beaked Whales, and saw four Sperm Whales!

The one we saw on Sunday was particularly friendly!

It was a fantastic weekend of pelagic birding.  Brian's spring trips are more popular because of the chance of better diversity, but in the summer the numbers of birds seen are generally much higher. The trend held true this weekend and we had plenty of space on the boat and hundreds of birds to see. 

Thanks again to Brian and Kate for having me along and to Kyle Kittelberger, who did a great job in his spotting debut. More info about these trips and the official counts and species list can be found on the Seabirding Blog; and additional (better than mine) photos here. 

Brian says there's room on most of the trips this summer; see www.seabirding.com/ for the schedule and booking information.
