Band-rumped Storm-petrel - Gulf stream waters, SE of Hatteras Inlet, North Carolina - May 26th, 2011. Flight style often compared to a small shearwater and somewhat evident in this shot. Overall quite warm brown, not so black-brown as Wilson's Storm-petrel. Digi-bin shot, along with all the other images in this post, taken using Canon Powershot A560 and Leica 8 x 42 binoculars.______________________________________________________________________________________________
*NB. There are still some spaces available on the forthcoming BBC Extreme Pelagic departing from Hyannis, MA at 4am on Saturday July 16th, 2011. The trip will target core eddies of warm water at the edge of the Continental Shelf which may attract rare species typically associated with the Gulf Stream. Band-rumped Storm-petrels will be high on the list of possible species, along with Audubon's Shearwaters, Bridled Terns and perhaps White-faced Storm-petrels. Rarities are being detected with increasing frequency on these trips and a rare pterodroma, such as the Black-capped Petrel we found July 2009, will be high on the 'wish list' for many.

Yet another dedicated offshore pelagic with the Brookline Bird Club is fast approaching, departing on Saturday July 16th. It seems like as good a time as any for a quick review of the Band-rumped Storm-petrels images I collected in North Carolina in late May.
Aside from Black-capped Petrels and the reasonable possibility of rarities, one of the species that I really hoped to see well on the North Carolina pelagics was Band-rumped Storm-petrel. My previous experience of Band-rumpeds was limited to just a handful of individuals seen rather fleetingly on the BBC extreme pelagics. Two days of pelagics off Cape Hatteras on May 25th and 26th produced about half a dozen Band-rumpeds on each day. They were often shy, rarely coming close to the boat and usually passed through the chum-slick without really hanging around (unlike the many tens of Wilson's Storm-petrels). It did, however, provide the opportunity I was looking for to get a firmer grasp of key identification features compared to Wilson's and Leach's Storm-petrels. My level of comfort increased with each and every observation and, once again, I was reminded that there is absolutely no substitute for field experience!
The photographers on board spoke of this species as being notoriously difficult to capture in images, something with which I'd agree. Even so, despite the distance and speed with which these birds worked around the boat, I was quite happy to come away with a handful of digi-bin images. Impressively, the crew of the Stormy Petrel II worked really hard to ensure that everyone on board had acceptable views of Band-rumped Storm-petrels. Thanks to Brian and his crew for announcing every individual bird!
Band-rumped Storm-petrel - Gulf stream waters, SE of Hatteras Inlet, North Carolina - May 25th, 2011. This bird shows a chunky impression, with fairly 'muted' carpal bars and a fairly long, broad 'arm' compared to Wilson's SP. The tail of this bird is also slightly notched.
Band-rumped Storm-petrel - Gulf stream waters, SE of Hatteras Inlet, North Carolina - May 25th, 2011. This bird shows similar features to the bird above, with dull, sullied carpal bars and looking rather long-winged and heavy-billed, and with a narrow band of white across the rump.

Band-rumped Storm-petrel - Gulf stream waters, off Hatteras Inlet, North Carolina - May 25th, 2011. Always looking longer winged and warmer brown compared to the many Wilson's Storm-petrels present.
