2018 Monhegan Spring Migration Weekend

IMG_9667-edited-edited
The most abundant songbird throughout the weekend, a flock of 125 Cedar Waxwings would ball up each morning and then spread out through the island to feed.

My annual “Monhegan Spring Migration Weekend” battled highs seas (seriously, it was rough and we were all thankful it was only a 1-hr ride!) to arrive on the wonderful island of Monhegan on Friday, May 25th. Five days later, I had two new birds for my Monhegan list, a total of 97 species including 18 species of warblers, and way too much of the best pizza in Maine.

After regaining our legs and equilibrium, we hit the ground running as always, birding our way to and from our hotel, lunch, and eventually dinner. No daylight was spared, and in doing so, we caught up with a few things, including the flock of 30 or so Red Crossbills, three of which perched nearby by close studies. Personally, however, I was most excited about 2 Eastern Bluebirds (at least one had been present for a while), my 210th species on Monhegan!  We had our first sighting of Warbling Vireo, which, like the 1-2 Field Sparrows – we saw everyday; both very uncommon on the island in spring. Apparently, I either started coming after – or perhaps only took better notes after – they last bred on the island. An island bird is a great way to start off the trip!\

Friday calmly eased us into the weekend, but Saturday blew us away. It was just one of those great days, with birds seemingly everywhere, and many of them low and easy to see. Following a moderate flight overnight on light westerly winds, there were a lot of new arrivals. Five Tennessee Warblers heard singing from one spot while tarrying at the Trailing Yew awaiting the coffee pot were a sign of things to come.

As is often the case on such flight days, we didn’t have to cover a lot of ground, as waves of birds were passing through the island and around town, pausing at just about every apple tree. It was hard to estimate the number of birds around, but there was a consistent south to north flow on the island, and several relatively-large flocks of the most common migrants of the day. I finally settled on 80 Red-eyed Vireos, 50 Blackpoll Warblers, and 20 Tennessee Warblers – impressive numbers of birds normally relegated to the tops of the highest oak trees, but today, more often than not, in low brush and short apple
trees.

While it wasn’t the kind of day that Monhegan legends are made of, it was one of the “good ol’ days” where migrants were plenty, views were crippling, and birding was easy.  And all of that was punctuated by a few goodies, including an immature male Orchard Oriole, three Eastern Bluebirds together (two appeared to leave the island shortly thereafter), a lingering immature Great Cormorant, my first Common Nighthawk of the year fluttering off the high cliffs of White Head, 14 species of warblers including 4 Cape May and 2 Bay-breasted, and much more. And the day ended with two American Woodcocks heard calling and twittering from the lawn chairs of the Trailing Yew.  That’s what Monhegan in migration is all about!

On Monhegan and elsewhere, a good birding rule of thumb is that if you see a blooming apple tree, you should look in it.

Not surprisingly, Sunday was slower, as light northeasterly winds precluded much in the way of overnight migration. And while it seemed that a lot of yesterday’s migrants had departed or melted into the woodlands, there were plenty of birds around, with a slight improvement in diversity, still plenty of Blackpoll Warblers, and a few highlights including a cooperative Green Heron, more Red Crossbills, a fly-by Black-billed Cuckoo, a Carolina Wren (finally; good to know one is here again), and a Northern Mockingbird (uncommon to rare out here) that we witnessed fly onto the island from behind, or perhaps over, Manana.

The afternoon was rather slow overall, but we just kept seeing birds well: the Warbling Vireo at eye level, a Lincoln’s Sparrow in the garden, and continued good views of Tennessee Warblers.

Monday the 28th was the last day of the tour, and with a smaller group in tow, we covered a lot of ground. While there was virtually no visible migration on the radar overnight on very light easterly winds once again, there were clearly a lot of new birds around (or at least, birds not seen the previous days) and we ended up with the best diversity of the trip – 71 species by day’s end.
Sunday am

In fact, by days’ end, we added 14 new species to our cumulative weekend list – not bad for a “slow” day and the end of a tour. And there was some quality to it, too: a continuing very late drake Long-tailed Duck that we finally caught up with…
IMG_9570-edited-edited

…a Brown Thrasher, a Red-bellied Woodpecker, Sharp-shinned Hawk, and especially the Brant that we found on Nigh Duck – my 211th all-time bird on Monhegan, and a new “island bird” for just about every birder on the island.

On Tuesday, it was just Jeannette and I on a one-day vacation, mostly on our own, but meandering in and out of contact with several friends on the island. We awoke to dense fog, but that rapidly lifted, and the strong (for the date) flight overnight produced another new arrival of birds. It sure wasn’t Saturday, but there were plenty more Blackpoll Warblers around, and warbler diversity overall was the best of the weekend with a total of 16 species, highlighted by the Mourning Warbler we found by the Mooring Chain, and an impressive 15 Blackburnian Warblers.

John and Terez found a (or relocated a brief late-last-week fly-by) Summer Tanager…
IMG_9833-edited-editedIMG_9844-edited-edited

…and we added a few new birds for the trip list including Great-crested Flycatcher, Northern Flicker, and had more species of butterflies today than total butterfly individuals all weekend, including an early Monarch. It was also a really, really nice day!
last-day_view

The afternoon was slower, and Jeannette and I winded down our visit with good conversation, one last slice (or two) of Novelty pizza and another pint (or two) of Monhegan Brewing beer, and caught up with some good friends who had just arrived with tours of their own. It was a relaxing finish to a great weekend, and the gentle boat ride home was more relaxing than we really needed before driving – just a little different than our outbound trip!

So yeah, it was a good trip. And, after one day at work, I am definitely ready to go back!  At least I have two tours out here this fall. First, I have a full week with my WINGS tour, space on which is still available.

And there’s a little room left on our store’s annual Monhegan Fall Migration Weekend tour, which is only four months away!

beets
I forgot to take a photo of the pizza – I ate it too quickly as usual – so here are some beautiful beets from the Island Inn.


And as migrants were passing through, many of the island’s breeding species were well underway, such as this Song Sparrow gathering food for its nestlings.

The Rarity Fever Juices are Flowing – It must be November, and There was a Storm…

Rarity season is upon us, and there’s no better time for a big ol’ storm. Especially with an impressive southerly flow before and during the storm, and a strong cold front clearing things out behind it, my “Rarity Fever” symptoms got fired up.

Just look at those extensive southerly winds on Friday and Sunday, for example…
wind map,10-28-15

…following Thursday’s storm system.
surface map, 10-29-15

Heavy rain Wednesday night into Thursday gave way to a few hours of well-above normal temperatures and mostly sunny skies before winds and rain began to pick up in the late afternoon ahead of the cold front. I was able to squeeze in a visit to Sabattus Pond in the early afternoon, hoping for storm-grounded waterbirds.

While it was simply gorgeous out, the waterbird numbers remained below seasonal-norms here. A continuing pair of Redheads was the highlight, and a pair of White-winged Scoters was just the type of rare-inland migrant seaduck I hope to find after some weathah’. Otherwise, waterbird counts were modest: 219 Ruddy Ducks (well, modest for Sabattus – this is an epic count for anywhere else in the state!), 164 Lesser Scaup, 75+ Ring-billed Gulls, 62 Mallards (not sure where the masses were today), 41 Bufflehead, 39 Greater Scaup, 36 Ring-necked Ducks, 16 American Coots, 13 American Black Ducks, 11 Canada Geese, 2 Common Loons, 1 Mallard x black duck hybrid, and 1 Double-crested Cormorant.

On Friday, with southwesterly winds (more rarity wind!) gusting ahead of a secondary cold front, I spent the morning in Cape Elizabeth. While I had Cave Swallow on my mind, I settled for a nice mix of late migrants, including four species of warblers (Orange-crowned at Kettle Cove, my 4th of the year; Blackpoll and “Western” Palm at Pond Cove, and scattered Yellow-rumps), a Gray Catbird at Kettle Cove, and an Indigo Bunting on private property.
BLPW,PondCove, 10-30-15_edited-1

With a light (but decent-for-the-date) migration overnight, I started at sunrise at “My Office” at Sandy Point to take in what’s left of the Morning Flight. Calm winds seemed to preclude as many birds from reorienting here as I would have expected based on the decent-for-the-date radar image overnight. However, it was a very pleasant morning with nice little flight featuring good late-season diversity. I tallied a total of 247 migrants, led by an even 100 American Robins, 66 Dark-eyed Juncos, and a nice total of 14 Snow Buntings. “Tardy” birds included 3 “Yellow” Palm Warblers, an Eastern Phoebe, 2 Hermit Thrushes, a Red-winged Blackbird, and best of all, a late Black-and-white Warbler that I found in the trees after my Saturday Morning Birdwalk group had joined me.

But on Sunday, vagrant-hunting was the name of the game. Although I did not organize a South Coast-wide “Rarity Roundup” this year for the first time in a decade, Kristen Lindquist, Evan Obercian, Jeannette and I ran my usual Portland Rarity Roundup itinerary, scouring the Portland peninsula for vagrants, “lingering” migrants, and other surprises. It was not exactly the birdiest of days on the Portland Pen’ but the Eastern Promenade was fairly productive, led by 2 Orange-crowned Warblers, a Palm Warbler, a Field Sparrow, and three Hermit Thrushes.
OCWA,EasternProm,11-1-15_edited-1
Here’s a terrible shot in the dawn dark and drizzle of one of the two Orange-crowns.

Elsewhere in the East End, we turned up a Hermit Thrush on Anderson Street, and a Gray Catbird on Sheridan Street, but then the passerines really dried up. The usually-productive stretch of woods on either side of West Commercial Street has been rendered useless, and was essentially devoid of birds.

On the riverside, there’s development, clearing a great stand of birch and scattered crabapples that once resided here:
IMG_6478_edited-1

But it’s a city, and development occurs, and there are lot worse places for trees to be cleared. The abandoned railyard and old docks along this stretch of degraded river is hardly habitat worth conserving. “There are more important places to protect,” as Evan stated. However, it was at least some habitat for tired and disoriented migrants that found themselves in the city and looking for food and shelter.

But degraded urban “brownfields” are exactly where development should occur. More frustrating – and rather perplexing – however, is the continued ravaging of quality habitat throughout the city by the City of Portland. From incredibly valuable parkland habitat at the Eastern Promenade to scattered thickets on undeveloped hillsides, it’s as if Portland doesn’t want birds to find refuge in the city. Of course, there are “other considerations” for this land mis-management, but that’s a blog for another day. But the misguided efforts to do whatever it is the city thinks it’s going to accomplish by clear-cutting what was the best strip of woods on the peninsula, reduced habitat for migrants – and resident species from Black-capped Chickadees to Hairy Woodpeckers, to Barred and Great Horned Owls (breeding) to this:
WestCommercialSt1,11-1-15

What a mess, and what an abomination! And what a waste. So yeah, there weren’t any birds here, either.

So after lunch, we gave up on the city (and crossed off several birding hotspots from the list…don’t get me started about what they have done to the Fore River Parkway Trail area!) and headed to Cape Elizabeth.

Unfortunately – especially with an increasing southerly wind in the afternoon – it wasn’t overly productive here. In fact, several of the best hotspots were incredibly slow – as slow as I have ever seen them at this time of year. However, we did hit some hotspots, led by a great amount of activity at Trundy Point. The five Snow Buntings on the beach were nice (photo below), but a feeding frenzy of 40+ Common and 6 Red-throated Loons, a single Red-necked Grebe, 1 Bonaparte’s Gull, and a goodly amount of Herring and Great Black-backed Gulls made for a fun visit. Northern Gannets were diving further offshore as well.
SNBU, 11-1-15

Maxwell’s Farm was productive, too: 17 Eastern Bluebirds, 5 American Pipits, and a Wilson’s Snipe led the way, and we had another snipe flying over little Joe’s Pond Park in South Portland. Mill Creek Park might have been the birdiest stop of the day – even if it was almost all Mallards and Ring-billed Gulls, however!

We then finished up the day, with the sun setting, at Portland’s Back Cove, with arguably the bird of the day – a late American Golden-Plover going to sleep with 9 Black-bellied Plovers and 5 Dunlin at the edge of the marsh. It was a nice way to cap an enjoyable day of birding with good friends, with the senseless optimism of Rarity Season keeping us going through nearly 14 miles of walking and searching.

No major rarities were to be found at Reid State Park on Monday morning, either, but Jeannette and I enjoyed a lovely, birdy walk on a beautiful morning. 8 late Semipalmated Plovers joined 151 Sanderlings on the beach, along with 8 American Pipits and 18 Snow Buntings. A lingering Nelson’s Sparrow (subvirgatus) was in the saltmarsh, and we spotted a Northern Harrier flying south, low over the water offshore. In the water, winter ducks and waterbirds are rapidly increasing: 31 Red-necked Grebes, 15+ Red-throated Loons, all three scoters, and a whole bunch of Long-tailed Ducks were among the growing legions today.

And then, I came into the store for a couple of hours of work this afternoon and was distracted by a Dickcissel at our feeders!
DICK,storefeeders,11-2-15_edited-1

After spending so much time sifting through urban House Sparrow flocks yesterday, of course one would show up right in front of me. It was a long overdue addition to our store’s yard list – #114! And it was my 5th mainland Dickcissel of the fall.

While the appearance of a vagrant after a storm could simply be coincidence, storms can facilitate the departure of already-wayward strays (to oversimplify things a bit). It’s hard to pin any one bird down to any particular weather event, but the appearance of a Swainson’s Hawk (about 6 or 7 state records) that was nicely photographed at the Cadillac Mountain Hawkwatch in Acadia on Friday, only served to further flare my Rarity Fever Symptoms. However, despite my best efforts, I didn’t turn anything of great significance up this weekend, and nor did anyone else in Maine.

From the lack of birdlife in many Portland spots (the ones that still have vegetation that is!) and especially in the warm Cape Elizabeth microclimates that I have been checking, it’s possible that the mild weather (remember we’ve only had that once cold snap so far) has simply not yet concentrated lingering/pioneering individuals and wayward vagrants in the little nooks and crannies that we seek them in at this time of year. And with a very mild week in store, perhaps it will be a little longer before we see them concentrate.

But there is one thing we can be sure of: there will be a “Mega” rarity soon. How do I know? Because I am going away during Rarity Season!

South Coastal Maine Rarity Roundup TEN!

BLPW,SheridanStreet,Portland,11-3-14
This Blackpoll Warbler was one of the record 9 species of warblers tallied on the day, and one of the top birds in my Portland territory. It was only the third time that this species was spotted by Rarity Roundup teams.

Each year on the first weekend of November, a group of us get together to scour the Southern Maine coast for vagrants, lingering migrants, pioneers, irruptive, and other seasonal highlights.  Coinciding with the peak of “Rarity Season,” we set out to use the geography of the Maine coast, coupled with knowledge of the best habitats and vagrant traps in order to find as many “good” birds as possible.  While this year failed to produce any “Megas,” we once again had a great day in the field, found lots of fun stuff, and enjoyed good food and beer at the Great Lost Bear at the end of the day (the real reason we all get together for this event!)

119 species were tallied by the 8 teams of the TENTH Annual South Coastal Maine Rarity Roundup, six species above our 10-year average, despite somewhat more limited coverage than in the past few years. The continuing “Audubon’s” Yellow-rumped Warbler was added to the cumulative checklist, while we also had our second-ever Snowy Egret, Prairie Warbler, and Nelson’s Sparrow.  Blackpoll Warbler and Clay-colored Sparrow appeared for the third time.

Most teams experienced a decidedly “birdy” day, especially from Portland through Scarborough.  A fallout of Dark-eyed Juncos, White-throated Sparrows, and Hermit Thrushes occurred with overnight northwesterly winds and a line of pre-dawn showers, with the fallout especially evident on the Portland Peninsula.  I’ll have more about the fallout on a blog entry later today.

Record high tallies were set for Pectoral Sandpiper (13), Northern Flicker (10), Carolina Wren (11), Hermit Thrush (52: the 26 in Portland alone was only one short of the previous all-time high), “Western” Palm Warbler (3), Chipping Sparrow (12), Field Sparrow (3; tie), and Lapland Longspur (37).  9 species of warblers was a new record as well, and Painted Turtle was added to our non-feather species list.  All but the longspurs can likely be explained by the unusually warm season to date.

Territory Highlights were as follows:

– Area 1, Kittery-York: Davis Finch.
1 NASHVILLE WARBLER, Legion Pond, Kittery.
1 Pine Warbler, Fort Foster.
1 PRAIRIE WARBLER, Fort Foster.
1 “AUDUBON’S” YELLOW-RUMPED WARBLER, Fort Foster.

– Area 2, Ogunquit/Kennebunport: Turk Duddy.
2 American Wigeon, Phillip’s Cove, Ogunquit.
1 Northern Pintail, Phillip’s Cove, Ogunquit.
1 Lesser Yellowlegs, Goose Rocks Beach.

– Area 3, Wells/Kennebunk: Doug Suitor, David Ladd, and Slade Moore.
2 Semipalmated Sandpipers, Webhannet Marsh
2 Gray Catbirds, Laudholm Farm.

– Area 4, Biddeford-Saco: Pat Moynahan, Marian Zimmerman, Joanne Stevens, et al.
1 NASHVILLE WARBLER, Saco Yacht Club.
1 CLAY-COLORED SPARROW, Timber Point.
1 NELSON’S SPARROW, Day’s Landing.
2 Lapland Longspurs, Day’s Landing.

– Area 5, Scarborough: Ed Hess, Noah Gibb, and Leon Mooney.
8 Great Egrets
1 SNOWY EGRET, Pelreco marsh
12 American Coots, Prout’s Pond.
8 LONG-BILLED DOWITCHERS, Eastern Road.
35 Lapland Longspurs

– Area 6, Cape Elizabeth: International Man of Mystery, Claudia, Robby Lambert.
2 “Western” Palm Warblers, private property
1 “Yellow” Palm Warbler, private property
1 DICKCISSEL, Higgin’s Beach.

– Area 7, South   Portland: John Berry and Gordon Smith.
1 Ring-necked Pheasant, Fort Williams Park.
1 Yellow-bellied Sapsucker, Calvary Cemetery.
1 Pine Warbler, Bug Light Park

– Area 8, Portland: Derek Lovitch and Kristen Lindquist; Jeannette Lovitch (Capisic and Evergreen); and a cameo by Doug Hitchcox.
2 Eastern Phoebes, Eastern Promenade.
1 BLUE-HEADED VIREO, Mercy Pond.
1 ORANGE-CROWNED WARBLER, Eastern Promenade.
1 BLACKPOLL WARBLER, Sheridan Street.
1 White-crowned Sparrow, West Commercial Street.

As usual, I exhaustively cover the Portland Peninsula and once again the most urban block in the state produced some great birds.  Kristen joined me for the second year in a row, while Jeannette (and Sasha) helped out with a few outlying patches.  Doug joined us just long enough to find the only White-crowned Sparrow of the entire day.  In addition to the goodies listed above, Kristen and I amassed 9 species of sparrows.

The fallout that I mentioned above was very evident in the morning, as we birded Portland’s East End. 150+ White-throated Sparrows and 100+ Song Sparrows littered the Eastern Promenade.  While Dark-eyed Juncos were fewer there, we encountered some big groups elsewhere, such as 60+ behind the East End School and 50+ in the lot on Sheridan Street, with 70+ later in the day in Western Cemetery. White-throats were everywhere: 50+ on Sheridan   Street for example.  And once again there was a decidedly disproportionate number of White-throated Sparrows in gardens and landscaping of downtown Portland.  A short loop from One City Center through Monument Square, behind Portland High, and back through Post Office Park yielded 35 White-throats, with the only other native migrant being 7 Hermit Thrushes.  Like the sparrow, Hermit Thrushes appear in a wildly disproportionate number to other migrants – especially all other thrushes – in downtown Portland.  I’m convinced that something causes White-throated Sparrows and Hermit Thrushes to either a) become disoriented by urban lights more often/more readily, especially under low ceilings (it was cloudy for most of the night and morning) or perhaps b) they simply don’t leave these lots in a morning flight as species such as Dark-eyed Juncos might.  In fact, I just read in an article in the Brown Alumni Magazine that a friend of the store dropped off about collisions in New York City that since 1997, more White-throated Sparrows have been found dead than any other species.  Coincidence?

Our sum of 26 Hermit Thrushes was truly amazing, as was our overall diversity on the day.  While the mild weather certainly has a lot to do with the number of lingering/pioneering birds that we, and other teams, encountered, the late-season fallout earlier in the morning certainly helped our cause.

Here are the overnight reflectivity and velocity images, with 10pm, 1am, and 4am once again used as an example.

At 10pm, there’s mostly rain in the area, but birds are mixed in.  By 1:00am, birds are on the move, as the rain has mostly moved into the Mid-Coast and offshore.  Birds were still on the go at 4:00am, as a narrow line of showers moved through the coast.  About an hour later, a steady rain developed (not shown) that continued until a short time before the 6:20 sunrise.  I believe this is why there were so many sparrows in and around the city come dawn.

In other words, it was another great day of birding in urban Portland in the heart of “Rarity Season!”
