Detailed Report

Day 1, 24th June 2021. Arrival in Portland with some evening birding

After gathering up everyone from the airport and checking into the hotel, we decided to venture out for some first-day birding. We headed off to Crescent Beach State Park for a nice evening walk along the beach where we enjoyed several nice species including Common Eider, Laughing Gull, Common Tern, Great Black-backed Gull and Double-crested Cormorant. While these were all great, the real highlight came in the form of nesting Piping Plovers, with recently hatched chicks running around like cotton balls with legs! We enjoyed these adorable birds for a while before heading to dinner and discussing our upcoming trip. What a great way to begin!

Day 2, 25th June 2021. Kennebunk Plains, Scarborough Marsh, Gilsland Farm

The morning started off with a quick stop for coffee before heading out to Kennebunk Plains for a nice morning session of birding. Today was dubbed “sparrow day” with loads of sparrow species as targets throughout the day, and the plains got us off to a fantastic start with Eastern Towhee, Vesper, Chipping, Field, and Grasshopper Sparrows. As we walked around the loop, we enjoyed the constant song and presence of Prairie Warblers, here on the northern edge of their breeding range. From here we enjoyed a nice brunch before heading out to Scarborough Marsh, one of Maine’s premier birding destinations. This massive marsh hosts loads of flats for waders and shorebirds where we enjoyed seeing Glossy Ibis, Snowy and Great Egrets, a rare Tricolored Heron and the eastern subspecies of Willet, a possible future split. Of course, don’t forget about the two amazing sparrow species which breed in these marshes. We had great views of both Saltmarsh and Nelson’s Sparrows (Atlantic subspecies) as well as a few birds which seemed to show characteristics of both—potential hybrids.

From the marsh we headed a little further south to Pine Point Beach. During our walk along the beach to the river mouth, we saw a few more Piping Plovers with chicks, who could get tired of them? We then spotted a decent-sized feeding flock out over the water where we were able to spend some time studying the differences between Roseate and Common Terns. From here we headed north to Gilsland Farm Audubon Center where we enjoyed several new species for the trip including Tufted Titmouse, Red-bellied Woodpecker, Great Blue Heron, and House Wren. From here we were off to dinner after a great first day of birding, satisfied with our “sparrow day”, that yielded ten different species of sparrows!

Day 3, 26th June 2021. Wharton Point and Seal Island National Wildlife Refuge

Today was full of excitement as we had our first scheduled boat trip! But first, we had to cover a decent drive to reach the docks in Stonington. We made a quick stop along the way at Wharton Point, a lovely grassland right on the edge of the water. Here we had several Bobolinks and a pair of Bald Eagles circling together and they even locked talons for a brief moment! Next it was off to the docks and our exciting visit to Seal Island National Wildlife Refuge.

Weather is always a big issue when dealing with the Gulf of Maine and today was no exception. Luckily, the waters had settled down slightly by the afternoon and our captain managed to get us out on the water, although conditions were extremely foggy. That didn’t stop us from enjoying our time. On our way out to the island, we managed to spot a Wilson’s Storm Petrel and a Northern Gannet flying near the boat before quickly disappearing into the misty abyss. We finally arrived at Seal Island and were treated to some close views of the many amazing birds that nest here including Atlantic Puffin, Razorbill, Black Guillemot, Artic Tern and Great Cormorant. In addition to the birds, we saw Grey and Harbor Seals plus a few of us spotted a Harbor Porpoise. We made it back to the mainland and over to our hotel and had dinner for the evening, all of us still basking in the enjoyment of the day’s many exciting seabirds.

Day 4, 27th June 2021. Acadia National Park and Cadillac Mountain

This morning we started off with some great breakfast in Bar Harbor and a hopeful spirit about our second boat trip, this time out to Petit Manan Island. Unfortunately, midway through breakfast I got the dreaded phone call to say that the winds were just far too high this morning and the trip was cancelled. We wouldn’t let that stop us from enjoying a nice day of birding though, so we quickly regrouped and headed out to Sieur de Monts Spring in Acadia National Park. Here we enjoyed several good species including Pileated Woodpecker, Brown Creeper, and American Redstart before Carly made an incredible find of a Barred Owl tucked deep in the canopy. We continued our exploration of the park stopping at the Precipice Trail where we scanned the cliffs and bagged a pair of Peregrine Falcons. We eventually made our way up to the top of Cadillac Mountain, enjoying the amazing views along the way. The summit was insanely windy with gusts easily approaching 50-60 mph, however we still managed to see a few species such as Hairy Woodpecker and a Myrtle (Yellow-rumped) Warbler feeding young. What started as an unfortunate cancellation turned into a great day birding Mount Desert Island and taking in all the many scenic viewpoints on offer here.

Day 5, 28th June 2021. Mount Desert Island and transfer to Machias

Today we started off back at Sieur de Monts Springs as this destination offers some of the best birding opportunities in Acadia National Park. The morning’s birding netted us several species that we had missed the day before including Ovenbird, Wood Thrush, and Northern Parula. The top highlight was probably a Red-eyed Vireo nest with at least four chicks being fed by mom. From here we headed around the scenic island and ventured over to the eastern side at Seal Cove. A short walk along the edge of the water produced Chestnut-sided Warbler, Western Osprey, and Common Yellowthroat. We then cruised along Seal Cove Road which produced a couple of magnificent species such as Blue-headed Vireo and Blackburnian Warbler. After this we started our drive to Machias where we would be spending the evening.

Day 6, 29th June 2021. Boot Head Preserve and Messalonskee Lake

This morning we headed off for some exploration of Boot Head Preserve which features some incredible, mossy-covered bog habitat. Along the way we encountered a few species including American Black Duck and Broad-winged Hawk. Once we arrived, we enjoyed a pleasant walk through the eerie, misty bog encountering such species as Golden-crowned Kinglet, Black-throated Green Warbler, Hermit Thrush, Lincoln’s Sparrow and Palm Warbler. In addition to the birds, the local flora here really stood out as unique with the flowering Purple Pitcher Plants a real highlight. From here, we were off to some breakfast before starting our long journey across the state towards the northwestern portion of Maine.

To break up the drive a bit, we had a planned stop at Messalonskee Lake, an interesting freshwater habitat which hosts several species difficult to find elsewhere in the state. We enjoyed some stellar views of breeding-plumaged Black Tern as well as other species including American Yellow Warbler, Warbling Vireo, Purple Martin, and a Common Loon with a chick following close behind. Eventually we ended up at our hotel and enjoyed a nice dinner. After dinner, we decided to check out a nearby area in hopes of a Moose sighting around dusk and while we had no luck with the giant mammal, we did enjoy some hearty laughs while out looking and great fun was had by all.

Day 7, 30th June 2021. Maine, New Hampshire, and Vermont birding

Today we had a very full schedule of birding planned across three different states. We started off the morning by heading towards the Boy Scouts Road. Along the way, we had our eyes peeled for our large mammal target. While slowing down in an attempt to get nice looks at a Northern (Common) Raven along the roadside, Devon spotted an amazing young bull Moose back along the brush line! What a serendipitous stop. This amazing animal paused and looked at us for a few moments before retreating back into the bushes and out of sight. An amazing start to the day but our roadside vigilance wasn’t over quite yet. As we continued up the road a few miles further, there was a bird-shaped blob on the side of the road which turned out to be a Ruffed Grouse! We quickly and safely got out and were able to track it as it wandered to the edge of the forest. Eventually we made it to the Boy Scouts Road where our morning hike yielded several nice birds such as Yellow-bellied Sapsucker and Red-breasted Nuthatch. We decided to carry on and leave Maine behind us as we ventured into neighboring New Hampshire.

Our first planned visit in this new state was East Inlet Road, a 12-mile-long stretch ending incredibly close to the Canadian border. Our first stop along the road was at a small lake hosting a pair of Common Loons. We made several further stops along this stretch, letting our eyes and ears guide us, which helped us locate several fantastic species including Yellow-bellied Flycatcher, Swainson’s Thrush and Boreal Chickadee! It was soon time to move on to Vermont and our final birding destination for the day, Moose Bog.

Again, we enjoyed another quiet bog, although noticeably different from the one at Boot Head. Pretty early on, Carly managed to spot a female Spruce Grouse deep in the dense woods but unfortunately it disappeared before anyone else managed a look, which is the name of the game in the birding world sometimes. We continued on searching for more grouse but overall, the bog was rather quiet. We did manage some lovely sightings however including a female Hooded Merganser with several chicks, a pair of Black-throated Blue Warblers, a Cape May Warbler and two American Beavers swimming out in the bog. Much to our chagrin, the grouse never made another appearance for us. We wrapped up and headed back to New Hampshire where we would spend the evening.

Day 8, 1st July 2021. Mount Washington and Wells Preserve

This morning we began our adventure up Mount Washington, the tallest peak in the northeastern US at 1,916m (6,288 feet). Down at the base of the mountain, there is a more open grassland-type area with a small body of water and some flowers where we spotted species such as Ruby-throated Hummingbird, Belted Kingfisher, and Eastern Bluebird. From here we slowly began our journey up the mountain, taking note of the four distinct habitat types as we climbed in elevation. We wanted to quickly reach the third zone, consisting of stunted-growth trees, to maximize our time searching for the top target bird. It was a very windy morning with some fog/clouds creeping onto the mountain but luckily it didn’t take long to find an accommodating Bicknell’s Thrush at approximately 1,250m (4,100 feet) in elevation. We continued on towards the top but quickly realized the fog was going to make any views futile, so we made a stop just before the view was inhibited where we enjoyed another Bicknell’s Thrush as well as a Myrtle (Yellow-rumped) Warbler and Dark-eyed Junco. As we birded slightly lower, it appeared the wind was calming down and the fog and clouds had lifted from the summit, so we climbed the rest of the way to the alpine zone at the top. Here we enjoyed the scenic views and managed to find a beautiful (American) Buff-bellied Pipit which called this rocky alpine area home. We slowly began our descent of the mountain, stopping about halfway down for lunch and some birding where we finally scored views of a Blackpoll Warbler. From here it was back to the Portland area for a final afternoon of birding.

We arrived at Wells Preserve at Laudholm Farm in the afternoon and found it to be quite birdy with Brown Thrasher, Brown-headed Cowbird, Veery, Northern Flicker, and House Finch, all showing for us. Eventually we made it to the saltmarsh here and had several Snowy and Great Egrets foraging in the shallow waters with more dropping in every so often. We decided to stay here a while in the hopes of a true rarity popping in, that had been seen in the area recently. Everything felt right and things seemed almost too perfect as more and more egrets were piling in until all of a sudden, we spotted a mid-sized egret with two very noticeable, long head plumes in flight… Little Egret! A true rarity for North America, we enjoyed watching this bird fish for quite a while and had absolutely stellar comparison views with nearby Snowy and Great Egrets, noting the size differences, grey lores and two head plumes. What an incredible sighting enjoyed by all. On our way out, we spotted a young North American Porcupine along one of the trails, an extremely exciting mammal encounter. This was the perfect finish to our final full day of birding in the northeastern US.

Day 9, 2nd July 2021. Departure day

On our final day, Marjorie and I went out for a final walk at Capisic Pond Park where we enjoyed several species including American Redstart and most importantly, we kept Marjorie’s eBird checklist streak alive! After this, our group (minus Carly) enjoyed one final breakfast together where we discussed all the fun moments of the trip. The favorites on this trip consisted of Atlantic Puffin, Little Egret, Bicknell’s Thrush, Barred Owl, and Saltmarsh Sparrow. We all said our goodbyes and wrapped up a great trip to the Northeastern United States.
