The 2023 Zeiss Pelagic Trip Report

Leave a reply

A southerly, and rather confiding, Common Murre was one of the unexpected highlights of the Zeiss Pelagic.

On June 2nd, we ran our now-annual spring mini-pelagic with our partners Cap’n Fish’s Cruises out of Boothbay Harbor. But this wasn’t any old pelagic. Instead, it was not only a way to poke your feet into the proverbial and literal pelagic birding waters, but this was also a chance to try out a new pair of Zeiss optics. And all for a very, very special price.

Thanks to our store’s partnership with Zeiss Optics, our biannual “Zeiss Day” occurred offshore this spring. With Zeiss’s sponsorship, we were able to offer this unique trip at a special price, with extra spotters to help people see birds, and of course, with chumming.

And the weather could not be any better! In fact, we were all excited to head offshore to beat the heat on this day. Barely a puff of breeze resulted in remarkably calm seas, with the only waves caused by our boat. Thanks to the weather gods for this day offshore!

Evan Obercian, Dan Nickerson, and Jeannette helped spot birds, Noah Gibb handled the checklists, and Robby Lambert – chummer emeritus – stood at the ready as the boat’s naturalist, Kelsey, and I scanned from the wheelhouse. Our captain was amazing, and together we laid out a plan for the day. Throughout the day, Rich and Bill from Zeiss handed out binoculars to try and lots of optical questions were answered. It was a great way to test-drive a new pair of excellent binoculars, especially noting how important size and weight is when trying to hold binoculars steady on the open ocean, even without much in the way of waves.

Motoring out of Boothbay Harbor and across Muscongus Bay, we familiarized ourselves with the common denizens of Maine’s summer coast, such as Common Eiders, Black Guillemots, Common Terns, and Ospreys. Kelsey pointed out landmarks and gave a little history of the area.

Our first destination was Eastern Egg Rock, home to a thriving seabird colony thanks to the restoration efforts of Project Puffin. Leading pelagic trips in June is easy when at least some of our target birds are guaranteed!

The amazingly calm conditions and unusually warmth worked in our favor, as many of the island’s Atlantic Puffins and Black Guillemots were in the water instead of loafing on the rocks, allowing us to drift closely to many of them. One of the island’s ephemeral Razorbills was spotted near the boat, giving us long and good looks as well.

Of course there were the terns, and for a change, both Roseate and Arctic were easy to isolate for all to see. With the help of my spotters, and a cooperative pair of Roseates on an obvious rock, everyone saw each species well, as well as many hundreds of Common Terns of course.  And a thousand or so Laughing Gulls, too.

Satisfied with our views of the island’s denizens, we turned offshore and followed the Arctic Terns to deeper waters. It wasn’t too long before we started seeing scattered Wilson’s Storm-Petrels, but we slammed on the breaks when I spotted a Common Murre on the water up ahead. Captain Steve was able to circle the bird for all to see and photograph before we continued on; the murre was most obliging.  It also made for the hoped-for 4-alcid day, which is always a challenge this far south.

The lack of swell allowed us to make good progress and afforded us the chance to check three offshore hotspots. A good number of Wilson’s Storm-Petrels and a few Northern Gannets were at Murray Hole, but we motored through it.

We laid down a mile-long chum slick at The Kettle, but only a few of the many Wilson’s Storm-Petrels came in to check it out. I think it was simply too calm today – the scent wasn’t drifting, and birds – especially any shearwaters out here – were just not taking flight to forage; it’s just too inefficient without any wind for them to bother. But a fly-by from a southbound Ruby-throated Hummingbird nearly 20 miles offshore was unexpected!

We continued to tally Wilson’s when we set up a second chum slick at Mistaken Ground, but once again, little was interested, and only a few Wilson’s and gannets were to be seen.

Despite our extended time with the charter, it was soon time to head back to port, but we kept our eyes peeled throughout the trip. On the way back, we had a flock of 12 Red-necked Phalaropes buzz by and eventually land on the water, but we were going too fast and behind schedule to be able to turn around in time. Later, we passed not one, but two Basking Sharks, which was a real treat.

Harbor Porpoise and Harbor Seals were seen now and again, but overall, the offshore waters were quite slow – especially with gulls. The few gulls around didn’t even seem interested in our popcorn and suet, either.

Robby contemplates the meaning of life…and chum.

Our tally of Wilson’s Storm-Petrels was decent enough, but sadly, this would be our only tubenose of the day. Northern Gannets were in low numbers, as if often the case in early June, and whatever shearwaters may have already arrived may simply have been sitting on the water somewhere waiting for a breeze. I also felt terrible that not everyone saw the phalaropes.

Nonetheless – thanks to a perfect visit at Eastern Egg Rock and a random Common Murre floating offshore – I would call the day a smashing success! And for $40, few complaints were audible. The weather helped, too.

Thanks to Zeiss for making this idea of mine come to fruition, and thanks to Cap’n Fish’s for letting us charter the boat to make this all happen. And most importantly, thanks to everyone who signed up and helped us explore the Gulf of Maine at this woefully under-birded time of year. Every day is different offshore, and you never know what you will or will not see. Excitingly, I am pleased to announce that Rich said, “let’s do this again next year!”  Hope to see you aboard!

Boothbay Mini-Pelagic with Cap’n Fish’s, June 6, 2022.

2 Replies

The first of our pelagic birding opportunities for the year took place on Monday, June 6th, as I joined the good folks from Cap’n Fish’s Cruises in Boothbay Harbor for a special ½ day mini-pelagic. 

We motored our way east to Eastern Egg Rock, looking at Common Eiders, Black Guillemots, Ospreys, and many other inshore denizens. Once we got to Eastern Egg Rock, however, the fun really started!  The cacophony of the colony was evident on this gloriously calm day, and it was not hard to find plenty of Atlantic Puffins in the water near the boat. 

We worked the masses of Common Terns to isolate a few great views of Roseate and Arctic Terns. The bright sunny day was a delight except for when trying to judge grayscale. That made tern identification a little more challenging, but we worked our way through it before departing the island for deeper waters. We had a good total of 7 Razorbills on and around the island, which is no guarantee on a visit here, and while we didn’t have the one Common Murre that has been lingering on the rock, we did have one fly-by later in the trip.

With seas barely 1-2 feet, just a puff of wind, and abundant sunshine, it was just a gorgeous day offshore. We cruised through a wide stretch of uneventful, flat bottom, but once we hit deeper waters, we began to see a number of Wilson’s Storm-Petrels. There were a lot more at our first deeper hole, but then when we got to our primary destination, it was clear how abundant they were.

We laid down a 4-mile long chum slick, and then slowly cruised back through it.  With the calm seas, it held together perfectly, and boy did it work!  It was actually incredible.  Unfortunately, other than a few Herring and Great Black-backed Gulls, it was 100% Wilson’s Storm-Petrels!

One of the ways to find other storm-petrels among masses is to look for the lack of obvious wing molt. This bird caught Jeannette’s eye because the wing is so clean and not showing any signs of flight feather molt. It’s a Wilson’s though, but could it possibly be another subspecies? Individual variation? Age?
Or, just something slightly different to look at?

But what a show they put on! Dan, Jeannette, and I did our best to estimate the abundance, as this was truly a special event. Our estimate of a trip total of 2,600 birds included an estimate of 2,000 in our chum line! 

We spotted the occasional Northern Gannet throughout the trip, but we desperately awaited another tubenose. Checking flight style, foot extension, wing bars, and underwing patterns, but yup, pretty darn homogenous.  As a leader, I tried to check every bird. But the sight was impressive, and I couldn’t help but utter superlatives and occasionally just sit back and enjoy the show.

We had to increase speed to make it back to the dock on time, but we continued to tally Wilson’s Storm-Petrels on the ride in. And Jeannette, Dan, and I worked hard to find something – anything! – else pelagic!  We don’t have a lot of data on what is out here in June, and it’s likely different every year depending on water temperature and breeding success and/or failure of these “winter” visitors from the sub-Antarctic waters. In fact, one some June whale watches I have been on, I haven’t had a single species of tubenose – let alone 2600 of them.

After last June’s adult Pacific Loon, I did have to have Captain Nick slam on the breaks when I spotted a decidedly gray-naped loon. When it surfaced, it was evident it was just a young Common Loon with an unusual amount of wear or bleaching on its head. It was worth a try though!

While our species list wasn’t legendary by any means, I’ve never seen this many Wilson’s Storm-Petrels in one, relatively short boat trip. In fact, this is by far the most I have ever seen together in Maine waters. Additionally, we had great looks at some of the Gulf of Maine’s most sought-after breeding seabirds to kick off the day at the birthplace of the Project Puffin.  And the weather, wow, the weather – what a day to be on the water!  And a great introduction to pelagic birding: the most exciting (and yes, at times frustrating) part of pelagic birding is every day, every trip, is so different, and it takes a lot of trips to appreciate the best of them.

We have two more trips planned with Cap’n Fish’s this summer. On July 15th, I’ll be joining the on-board naturalist for a visit to Eastern Egg Rock followed by a little birding-while-whale-watching. Then, on October 11th, it will be the second of our dedicated half-day pelagics, including chumming. Since we won’t have activity at Eastern Egg Rock at that time of year, all our time will be dedicated to finding birds offshore.  Information and registration for these two trips – and our summer tours to Seal Island as well – can be found on the Pelagics Page of our website.

Here is our complete trip list, from the time the horn blew as the boat pulled out of the dock until we returned to the slip. Our estimates at Eastern Egg Rock are very conservative, and likely dreadfully low. Offshore, we worked hard at estimating individual groups of storm-petrels and tallying exact numbers of other birds offshore. There were also likely many more eiders, guillemots, and cormorants on the outer islands, but our focus was on finding more seabirds!
