A Field Guides Birding Tours Report

Maine in Fall: Seabirds & Coastal Migrants 2022

September 8-17, 2022 with Eric Hynes guiding

The number of incredible looks we enjoyed at South Polar Skuas, all showing heavy wing molt, was unprecedented on this tour. Photo by guide Eric Hynes.

Throughout this tour, I kept saying that one of you must have a lucky rabbit's foot in your pocket. Everything seemed to fall into place for us on the 2022 run of Maine in Fall with Field Guides. The hurricane stayed far enough out in the Atlantic Ocean to not impact the pelagic trip, it was warm and sunny for most of the tour, we got NW winds overnight while we were out on Monhegan Island and many exciting species allowed excellent looks. Most important to me as the guide was how wonderful you all were to each other and what a pleasure it was for me to go birding with you -- thanks!

The tour began in the southern coastal area and we enjoyed some exciting salt marsh, mud flat and beach birding. Species highlighting our visit to Scarborough Marsh, Pine Point and Biddeford Pool included: a handsome juvenile Baird's Sandpiper, a molting adult White-rumped Sandpiper, crisp juvenile Short-billed Dowitchers, a curious hybrid wader presumed to be a Snowy Egret x Tricolored Heron, our first of many Merlins, plus Saltmarsh and Nelson's sparrows.

Our time based out of Bar Harbor was particularly rewarding. This year's Maine Audubon pelagic was one of the best anyone could remember. Red-necked Phalaropes were sprinkled across the surface, there was a clean sweep of the four Alcids including Atlantic Puffin, dozens of Pomarine Jaegers were around, plus a Parasitic, Great Shearwaters by the thousands with a fair amount of Sooty Shearwaters mixed in and several unexpected Cory's Shearwaters. Did I mention the ten South Polar Skuas?! Our boat cruise on Passamaquoddy Bay was spectacular in its own right. We had excellent looks at Great Cormorants right from the start. Old Sow was really churning -- "piglets" and upwellings all over the place. Bald Eagles were cooperative and we picked through Bonaparte's Gulls by the hundreds. Eventually we came upon an adult Little Gull that gratefully held its perch on a rock. We spotted several Black-legged Kittiwakes on the rocks below East Quoddy Lighthouse. Motoring back in turned up point blank Common Loon, Gray Seals, Razorbills and Common Murres. Acadia National Park offered stunning landscapes and a variety of bird species but it is hard to remember any of them except the abundance of Red-breasted Nuthatches and Red Crossbills. Clearly, both species are irrupting into Maine this fall.

The final leg of our journey was spent on the enchanting Monhegan Island. While the vegetation held a number of songbird species, it was the raptors overhead that kept drawing our attention. Merlin ended up the bird of the tour thanks to the countless dramatic sightings of birds in flight and perched.

One final morning at Scarborough Marsh cleaned up Nelson's and Saltmarsh sparrows for some people and we added Bobolink, Pectoral Sandpiper and Spotted Sandpiper to the list.

Thanks again for choosing Field Guides and I hope to bird with all of you again, sooner than later!

Cheers,

Eric

The default sandpiper in Maine in fall migration; predominately juveniles at this date

Field Guides Birding Tours
This Common Loon looked as startled to see us as we were to see it when it popped up on the surface only a few feet off the port side of the boat during our Passamaquoddy Bay cruise. Photo by guide Eric Hynes.

Beautiful looks at juveniles at Dunstan Landing

Plenty

It is always thrilling to catch up to a Little Gull -- the smallest gull in the world. Photo by guide Eric Hynes.

LESSER BLACK-BACKED GULL (Larus fuscus)

This rarity isn't so rare anymore

GREAT BLACK-BACKED GULL (Larus marinus)

By far the most memorable one was the juvenile that needed a lot of help untangling all that fishing line. I hope it recovered.

COMMON TERN (Sterna hirundo)

Good looks on multiple occasions

ARCTIC TERN (Sterna paradisaea)

Most have left the breeding colonies by the time we run the tour but we caught up to several during the Maine Audubon pelagic, including a crisp juvenile that stayed in the wake for several moments as we returned to Frenchman Bay

Gaviidae (Loons)

COMMON LOON (Gavia immer)

The calling bird(s) at Long Pond was unforgettable but don't forget the unbelievable look we enjoyed at Head Harbor Passage

So many great looks at these pelagic wanderers

Procellariidae (Shearwaters and Petrels)

CORY'S SHEARWATER (Calonectris diomedea)

In the 23 years that Maine Audubon has been running this trip, this species has only been recorded a couple of times and the previous high count was just one. A species typically in warmer waters, the fact that we saw several is an indication of climate change.

Field Guides Birding Tours
It was fun playing "Where's Waldo" whenever we came across a big flock of Great Shearwaters on the water. Its yellow bill made it easier to spot the regional rare Cory's Shearwater among them.

GREAT SHEARWATER (Ardenna gravis)

Seeing thousands so well was a real treat

SOOTY SHEARWATER (Ardenna grisea)

It seemed like every time we encountered a large flock of Great Shearwaters, we were able to tease out a few Sooty Shearwaters

Sulidae (Boobies and Gannets)

NORTHERN GANNET (Morus bassanus)

These dynamic seabirds are always such a thrill to watch

Phalacrocoracidae (Cormorants and Shags)

GREAT CORMORANT (Phalacrocorax carbo)

Most were spotted while driving

BALD EAGLE (Haliaeetus leucocephalus)

It is wonderful to see how much this species has recovered

RED-SHOULDERED HAWK (Buteo lineatus)

This species is few and far between in Maine so it was a real surprise to spot an adult perched roadside on our drive to Bar Harbor. Unfortunately, it was not in a very good spot to pull over for a better view.

BROAD-WINGED HAWK (Buteo platypterus)

The most frequently sighted raptor while we were on the mainland

RED-TAILED HAWK (Buteo jamaicensis)

A few here and there

The group finally caught up to one during the gull rescue

DOWNY WOODPECKER (Dryobates pubescens)

Several individuals seemed oblivious to our presence

HAIRY WOODPECKER (Dryobates villosus)

They are not asking, they are telling when they call. Our first good look was at Sieur de Monts Spring

PILEATED WOODPECKER (Dryocopus pileatus)

What a dramatic beast; exciting enough to merit turning around, though we saw plenty by the end

NORTHERN FLICKER (YELLOW-SHAFTED) (Colaptes auratus luteus)

A conspicuous migration was underway while we were on Monhegan

Falconidae (Falcons and Caracaras)

AMERICAN KESTREL (Falco sparverius)

Not nearly as aggressive as the next species

MERLIN (Falco columbarius)

Voted the bird of the tour thanks to the countless good looks while on Monhegan: perched, chasing prey, chasing each other, harassing larger raptors...the works

PEREGRINE FALCON (Falco peregrinus)

Surprised it took us to the last morning on Monhegan to catch up to this amazing predator

GOLDEN-CROWNED KINGLET (Regulus satrapa)

Heard more than seen

Sittidae (Nuthatches)

RED-BREASTED NUTHATCH (Sitta canadensis)

Wow - quite an irruption underway! The concentrations on MDI were remarkable. The chorus of their little, nasal "yanks" was a welcomed soundtrack throughout

WHITE-BREASTED NUTHATCH (EASTERN) (Sitta carolinensis carolinensis)

It will be interesting to see if the birds in eastern North America get split from the noticeably different-sounding birds in the West

Certhiidae (Treecreepers)

BROWN CREEPER (Certhia americana)

We had to work for this one. Eventually, we scored a really good but neck-straining look on the Ship Harbor Trail in Acadia National Park

AMERICAN GOLDFINCH (Spinus tristis)

Nearly an every day species

DARK-EYED JUNCO (SLATE-COLORED) (Junco hyemalis hyemalis)

Seen well on the Valley Cove Trail

WHITE-THROATED SPARROW (Zonotrichia albicollis)

Materialized in the community garden right in front of us on Monhegan

NELSON'S SPARROW (ATLANTIC COAST) (Ammospiza nelsoni subvirgata)

A couple of birds held their perch in the Spartina at the beginning of the tour but were quite obstructed by vegetation. The looks during our last stop (literally) of the tour were way more satisfying

SALTMARSH SPARROW (Ammospiza caudacuta caudacuta)

This crisper plumaged cousin to the previous species showed very well for us at Dunstan Landing the last morning

SAVANNAH SPARROW (Passerculus sandwichensis)

Seen well near the beach in Biddeford

Dozens on Monhegan

Plenty of good looks

AMERICAN REDSTART (Setophaga ruticilla)

More days than not
