For the past couple months, Ian Davies and I had been eyeing this week for a little summer Cape Cod birding adventure. The feasibility of this plan would depend largely on the weather, as I wanted to trailer the boat to the Cape for access to pelagic waters and Monomoy NWR. After a rather uncertain and oft-changing forecast thanks to a stationary front passage, a brief weather window opened for the second half of the week. Julian Hough was free to join me for the mini vacation, so we left CT on Tuesday evening. Wednesday was spent shorebirding; Ian had to work that day, but Pete Trimble and Phil Rusch filled out the boat. Thursday found us rained out, but we regrouped for a full Friday on the water.
At sunrise on Friday the 12th, Ian, Julian, and Pete & Jeremiah Trimble and I left the harbor and headed around the tip of Monomoy to the productive waters east of Chatham. I had been out there a handful of times prior between my boat and a friend's, and there has always been at least something to see between pelagic birds and cetaceans. At their best, these waters are teeming with marine life. Friday's experience was very bird-centric. Hundreds of shearwaters, storm-petrels, gulls and terns were scattered over a broad piece of water about 3-5 miles offshore. There were no massive tight flocks. Rather, the tubenoses were following scattered topwater feeding fish. Based on what I was seeing, I suspected most of the predatory fish were Striped Bass, though I did see a schoolie Bluefin Tuna leap out of the water at one point. The calm waters were perfect for spotting whales, dolphins, or sharks, but surprisingly we had none of those. Just one Mola Mola.
As we were pulling out of the harbor earlier that morning, we threw together a wish list of rarities we could find out there. Some more outrageous than others, though all were incredibly unlikely. Jeremiah's request for the day was Cape Verde Shearwater - a lofty goal! Well wouldn't you know it if Jeremiah didn't point out a small, dark Cory's-type shearwater with a dull bill around 7:20 am. Wow. That's double points for calling your own shot.
The fun part about observing pelagics from a small boat is that you can get quite close to the birds, as the spectre of a 20-foot boat is nothing compared to the large vessels we charter for typical pelagic trips. We were already quite close to this individual, which was in a loosely scattered line of Great Shearwaters.
Once Jeremiah pointed it out, bins and cameras were raised. Unfortunately our time with the bird was all too brief. One by one the Great Shearwaters and the Cape Verde Shearwater lifted off the water and flew dead away. We gunned the boat in pursuit as best we could, but the birds effortlessly motored away from us, which is saying something since we were doing 30mph.
Following a group huddle and back-of-camera photo sharing, we quickly came to a consensus on the ID, though it did take a few moments to shake off the shock. Cape Verde Shearwater is a species that has been recorded off the East Coast at least once before (a well-documented August 2004 record by Patteson et al. off Hatteras, NC), so we had all been geared up for this ID for years. Despite nobody on board having field experience with the species, this bird clearly checked all the boxes in textbook fashion with good views and photos to boot. A life bird for everyone on board.
Initially seen sitting on the water near a few scattered Great Shearwaters, naked eye this bird appeared small and dark for a Cory's type. Similar in size to the nearby GRSH. After changing the path of the boat slightly to put the bird more broadly on the port side, I got bins on it briefly, and a thin, anemic grayish bill with a darker tip was apparent; certainly not the clear yellow bill you see on Cory's/Scopoli's. Then pulling up the camera, I got only two frames with the bird on the water before it picked up, started towards us, then turned away and continued in this fashion until out of view while we pursued. Its flight style seemed much less deliberate/lumbering than Cory's to me, not surprising given the bird's apparent size and narrow wings. Photo review revealed a lack of any white bleeding onto the under-primaries. Thin white eye arcs stood out against a subtly dark face/cap.

Cape Cod is well-known as a seabirder's paradise, and this bird's occurrence only reinforces that fact. Given how many birds work this area on a regular basis, perhaps it should come as no real surprise that a mega rarity like this would pop up just a few miles offshore.

Just an awesome day on the water with great people among one of the region's finest wildlife spectacles. It is tough to beat late summer birding on Cape Cod!

After three years of trying, Dave Provencher and I finally made it to Madeira in search of Zino's Petrel. The pandemic had postponed our 2020 and 2021 bookings, but we were not denied this time around. We spent about 5 days on the island, three afternoons of which were at sea. The rest of the time was spent casually exploring from sea level to 6,000+ ft peaks. We connected reasonably easily with the island's few endemic species and subspecies, plus a few other target birds.
Madeira is a small island whose jagged peaks jut out of the ocean like the tip of an iceberg. Information about the island is readily available online, so I will spare the repetition here. Though I will add one thing that surprised me...Madeira is very affordable. Cheap, even. At least once you get there. Flights seemed to run $650-800 return from the northeast US, but once on-island, our stay did not set us back much. The rental car cost $215 for the duration, our downtown Machico hotel room was $55/night, and dining ran cheaper than back home. Our getaway was brief, and there was more island to explore for sure, but I do recommend Madeira as a destination if you like yourself some rare Pterodromas.

The stars of the show...ZINO'S PETREL. We encountered at least 7 individuals over our three afternoons at sea.
