A Field Guides Birding Tours Report

Maine in Fall: Seabirds & Coastal Migrants 2021

September 9-18, 2021 with Eric Hynes guiding

Thanks so much for getting fully vaccinated and choosing to travel again with Field Guides in these wildest of times! Your attitudes and understanding were greatly appreciated. Any tour in Maine is a homecoming for me so it is always a treat to share some of my favorite birding locations and adventures. The fact that you were all such a respectful and harmonious bunch made it extra special.

Hurricane Larry stayed way out to sea but its slow progress and massive size managed to impact our itinerary right from the start. Once I was informed that the Maine Audubon pelagic trip was canceled, Tour Manager Ruth Kuhl and I scrambled to put Plan B in place. In the end, in some ways, the shuffling of the itinerary might have been a blessing.

Our adventure began on a rainy evening in the Portland area. We headed to Scarborough Marsh and tallied our first species from observation points behind the Pelreco Building, at the Lobsterman's Co-op at Pine Point and at Pine Point Beach. We enjoyed a direct comparison of Lesser versus Greater yellowlegs in the same scope view and a diversity of herons and egrets. Shorebirds such as Black-bellied and Semipalmated plovers made the list but the fog really limited the quality of our first looks. A flock of Wild Turkeys were spotted, as well as several Belted Kingfishers, which proved to be nearly a daily occurrence for both species.

Day two began under more pleasant weather conditions with a walk at Timber Point in Kennebunkport, followed by a visit to Goose Rocks Beach. Broad-winged, Red-tailed and Cooper's hawks were noted but the state endangered Piping Plovers had already departed toward their wintering grounds. The lunar cycle, combined with the swell Hurricane Larry was generating, made for a magical shorebird experience while we enjoyed our lunch at Biddeford Beach. Hundreds of shorebirds were pushed right up to the dune edge. We sat quiet and still on our stools marveling at the frantic foraging of the more numerous Semipalmated Sandpipers and Sanderlings. Our patient approach was rewarded with an outstanding study of Dunlin, Ruddy Turnstone, Least, White-rumped and Western sandpipers as well. A pair of American Oystercatchers, rare breeders in Maine, flew by and we were able to catch up to them roosting on some rocks near East Point. Our only Black-crowned Night-Herons of the tour were snoozing the day away on the back side of Great Pond. Always observant Rita surprised us with her discovery of a bright Dickcissel at Kettle Cove and we finished the day at Dyer Point with lobster rolls, while spectacular waves crashed against the rocks.

Saturday was our transition day up to Bar Harbor, but before we left the southern coast, we improved our views of Common Eider, Short-billed Dowitcher, and Least Sandpiper, heard a flushed Wilson's Snipe, plus a surprisingly good view of a Nelson's Sparrow. Species nearing the northern edge of their range like Red-bellied Woodpecker, Carolina Wren and Northern Mockingbird were noted. An odd wading bird, possibly a Snowy Egret x Tricolored Heron hybrid was studied behind the Pelreco Building. My brother's place in Augusta, Cushnoc, was a hit for lunch and we followed this up with a visit to Messalonskee Lake in Belgrade where we observed our only Sandhill Cranes and Pied-billed Grebe of the tour.

Acadia National Park has so many wonderful sites but I always like starting at Sieur du Monts Spring. A mixed flock greeted us right in the parking lot with super views of Red-eyed Vireo, Black-and-white Warbler, Northern Parula, and Black-throated Green Warbler. A majestic Pileated Woodpecker chiseled away at a snag while we discussed the various pronunciations of its name. Our only Blackburnian Warbler of the tour and hard-to-spot Brown Creepers were eventually found. The ponds behind Mount Desert High School attracted handsome Wood Ducks and keen-eyed Rita once again brought our attention to an exciting phenomenon. Watching newly hatched Snapping Turtles emerge on the surface was a nature moment I think we will all remember forever. Our first good looks at Lesser Black-backed Gulls were enjoyed during our lunch break at Seawall. Kinglets, warblers and scope views of Common Loon and Black Guillemot highlighted our afternoon stroll around the Ship Harbor loop trail.

Monday began with an out and back walk at Valley Cove before retreating to Bar Harbor to board the Friendship V. Bar Harbor Whale Watch Company hadn't offered a trip in three days because of the hurricane so our adventure was more crowded than any of us would have liked. Despite the capacity crowd, a number of noteworthy species were encountered that made the trip more than worthwhile. Our best look at Atlantic Puffin came in part because we had slowed down for a large shark (Great White?). Northern Gannets and Wilson's Storm-Petrels were present during much of the cruise and multiple flocks of Red-necked Phalaropes were observed. Presumedly, the complete absence of jaegers, skuas, shearwaters and fulmars was the influence of Larry.

On the 14th, we headed all the way Downeast for a walk at Boot Head Preserve followed by a visit to the easternmost point in the United States at West Quoddy Head Light. Our first Black-legged Kittiwakes and Great Cormorants were on the large rock just off-shore. The only Surf Scoters of the tour we scoped during the picnic lunch we enjoyed at the South Lubec Flats. In the afternoon, we made our way around to Eastport and joined Captain Butch of Eastport Windjammers to cruise the nutrient-rich waters of Passamaquoddy Bay as far out as Head Harbor Passage. The rarest bird of the trip, an adult Little Gull, was seen well shortly after leaving the dock while we were mesmerized by the swirling waters of Old Sow, the largest natural whirlpool in the Western Hemisphere. At least four Minke Whales were seen well, plus dozens of Harbor Porpoise. Most remarkable on this journey were the incredible looks we had at Razorbill and Common Murre!

When we departed Bar Harbor, we headed up to the boreal forest outside Milford and picked up Swamp Sparrow, Palm Warbler and a fantastic look at an Ovenbird walking along a branch. The rest of the day was spent getting out to Monhegan Island. On the ferry ride across, aboard the Elizabeth Ann out of Port Clyde, we witnessed one of the more dramatic moments of the tour: a Peregrine Falcon chasing a Ruddy Turnstone in the wake of the boat.

Our tour concluded with several lovely days exploring the always enchanting and relaxing Monhegan Island. Our best looks at Merlin and Sharp-shinned Hawk occurred there as well as additions to the list of Hermit Thrush, Mourning Warbler, Baltimore Oriole, Eastern Kingbird, Rose-breasted Grosbeak, and Bobolink.

Thanks again for choosing Field Guides and I look forward to our next adventure in the field together!

Cheers and good birding,

—Eric
