This Week in Shorebirds: 8/22-28/2015


Two juvenile Baird’s Sandpipers at Popham Beach State Park on Friday morning, “rare-but-regular” fall migrants.

August is for shorebirds. Although the “fall” southbound migration started in late June (when the first non-breeders begin to turn around to mosey back south) and continues into November when Purple Sandpipers are still filling in, August is the month of peak numbers and diversity in Maine.
Most weeks from mid-July into September of recent years, I post a weekly “shorebird high counts this week” summary to my weekly “Additional Highlights This Week” summary posts to the Maine-birds listserve. While I do hope this is interesting and of value to folks, I also do it to organize my own notes, allowing me to quickly reference the peaks and valleys of particular species with ease should I need to.

I generally only post this when I have hit at least two “primary” and at least one “secondary” site each week, to make the numbers meaningful. And I prefer at least one prime high tide location (Eastern Road Trail in Scarborough Marsh, Biddeford Pool Beach/Ocean Avenue, or Popham Beach State Park in some years) with one low or mid-tide hotspot (Pine Point, Hill’s Beach/The Pool, or Popham and nearby environs).

This week was a particularly productive week for my own shorebirding, so this week’s summary is a helpful future reference for me. I also thought it was worth going into a little more detail, since it yielded a goodly 21 species (plus one subspecies) and some excellent totals.

The inclement weather of the weekend into the middle of the week (regular rain, lots of fog, easterly or southerly winds) was perfecting for “grounding” shorebirds and allowing numbers to build. I think my only surprise was my lack of a real rarity – like Western Sandpiper (although I worked pretty hard for one!)

I hit the low-tide hotspot of Pine Point on Monday with Jeannette, followed by the Eastern Road Trail at high tide later that afternoon. Jeannette and I spent the incoming to high tide at Biddeford Pool Beach on Tuesday, and on Friday, Serena Doose and I visited Popham on the incoming to high tide. Additionally, Jeannette and I checked one of the “secondary” sites, Brunswick’s Wharton Point on Tuesday and on Thursday I visited Wells Harbor before the evening’s Scott Weidensaul talk that we co-sponsored with Birds and Beans coffee and York County Audubon.

It’s always good to hit a freshwater location for diversity and high counts of pond-preferring-migrants, so when my Poplar Hut Tour Group with Maine Huts & Trails visited the Carrabassett Valley Snowfluent Ponds on Sunday, my high counts of Spotted and Solitary Sandpipers were acquired, along with my only Wilson’s Snipe of the week.

And, as if often the case during the peak of shorebird migration, there is some other “incidental sighting” of a migrant in some weird place – but not as weird as the Whimbrel (my only of the week) foraging at 4,200 feet atop Sugarloaf Mountain that Paul Doiron, Kristen Lindquist, and I observed on Sunday afternoon. While I knew they forage on mossberry during migration, such as in the bogs Downeast, I was most definitely not expecting one up here!

Therefore, with a total of 7 shorebirding locations – plus that mountaintop Whimbrel! – “this week’s shorebird high counts” scoreboard looks like this:

Of course, it’s not just shorebirds that are on the move – there are plenty of passerines as well! A migrant Wilson’s Warbler and a whopping 14 Ruby-throated Hummingbirds were at Old Town House Park on Saturday morning when I visited it with my Saturday Morning Birdwalk group. My tour group to the Poplar Hut encountered mixed-species foraging flocks as we hiked to and from the hut, highlighted by an immature female Cape May Warbler in a little wave around the hut itself on Sunday morning.

Other highlights this week included 14 Wood Ducks and a bumper crop of juvenile Common Yellowthroats at Florida Lake Park (8/24), the whiter of the two Tricolored Heron x Snowy Egret hybrids (“Splotchy”) in the Rte 1/9 salt pannes in Scarborough Marsh with Jeannette on the same day and a drake White-winged Scoter off of Biddeford Pool Beach on 8/25.

While a diversity of shorebirds will continue for several more weeks (and there’s a better chance for Western, Baird’s, and Buff-breasted Sandpipers), I tend to spend less time focusing on them (and therefore not enough time at enough prime locations over the course of the week), and therefore only occasionally post summary totals. In fact, if the much-reduced numbers at Popham today are any indication, a lot of shorebirds departed with the passage of this recent cold front.

Instead, I spend most of my free mornings now at “my office,” the bridge at Sandy Point Beach, Cousin’s Island, Yarmouth, observing and obsessively counting migrant passerines in the “Morning Flight.” In fact, my first visit of the season there on Thursday morning yielded 438 migrants, including 17 species of warblers, 1 early Dickcissel, 1 Blue-gray Gnatcatcher (my 3rd-ever here), and 5 Prairie Warblers – my 2nd highest count.

(Much) more on that soon.

“Birds on Tap – Roadtrip: Shorebirds and Beers!” Trip report, 8/2/15

It’s pretty clear that I am not the only birder who loves beer. And based on the success of the “Birds, Books, and Beers” series at Maine Beer Company, the first of hopefully many “Birds on Tap!” lectures at Rising Tide Brewing, and the fact that many of my tours finish the day at a brewery (e.g. Monhegan Brewing), I was looking for a way to build on these events.

Enter the “Birds on Tap – Roadtrip!” series with our friends at the Maine Brew Bus. And the first of what we hope will be a regular schedule of unique birding and beer-ing outings took place on Sunday.

Combining three hours of birding with visits to two of our great local breweries, we strive to showcase some of Maine’s best birding, and best craft brewers. Beginning in August, there’s no better place to bird in southern Maine than Scarborough Marsh.

After two convenient pick-ups, one at the store and one in Portland, it was down the marsh, starting at Pine Point on the incoming tide. Common Terns were feeding in the channel, and we took a moment to check out the truly beautiful turquoise eye of a nearby Double-crested Cormorant.

Out on the mudflats, 150+ Semipalmated Plovers were joined by at least 75 Semipalmated Sandpipers, 30 or so Short-billed Dowitchers, 15 “Eastern” Willets, and a few Black-bellied Plovers. As the ride rolled in, many of these birds flew closer, landing on the last strip of mud and sand right in front of us, offering detailed study of plumage details to complement the “general impression of size and shape” methodology of identifying birds afar.

Some birds, like this Semipalmated Plover, were incredibly close and offered great studies of plumage detail.

Our next stop, with the tide approaching high, was the Eastern Road Trail. The wide, raised trail crossing the marsh provided convenient access and easy viewing of the many hundreds of shorebirds out in the salt pannes. 300+ Semipalmated Sandpipers, 100-150 Semipalmated Plovers, 100+ Short-billed Dowitchers, 50+ Least Sandpipers, 20+ Greater and 6 Lesser Yellowlegs, 2 “Eastern” Willets, 2 White-rumped Sandpipers, and a single Spotted Sandpiper.

Joining the shorebirds in the pannes were a variety of wading birds, with 40+ Snowy and 25 Great Egrets, 8 Glossy Ibis, 4 Great Blue Herons, 3 Little Blue Herons, and “Patches:” the ultra-rare Tricolored Heron x Snowy Egret hybrid that has been frequenting the marsh for at least three summers now.
There were a lot of birds in the pannes today, with shorebirds covering all of the exposed mud and wading birds standing guard at the edges.

Several singing Nelson’s Sparrows, including a couple of birds that offered unusually prolonged scope-views, a soaring Bald Eagle, and a hunting Northern Harrier added to the diversity of the day.

As we enjoyed some scrumptious vegetable hand-pies, Josh took over the show, and escorted us down to Saco’s Barreled Souls. While several birders got a life bird or two today, everyone in the group had their “life beers” from Barreled Souls. All of Barreled Souls’ beers are fermented in oak barrels using a version of the Burton Union system, a method developed in England in the 1800’s. Unique ingredients coupled with this system that offer subtle flavor additions and changes to the beer, provides a healthy growing environment for the yeast that does the dirty work of making the sugar into alcohol, and allows for the capture the healthiest yeast crops for the next batch of brew.

We received a tour of the facility, before being invited in the cozy tasting room. All the while, four unique and very flavorful beers, all very different in taste and body, were sampled, including Half-Nelson, an IPA with 100% Nelson Sauvin hops and Space Gose, a tart German style beer with coriander, Maine sea salt, and lemon zest. Mixing things up a bit, the fruity Eat a Peach and the finale, the malty and nutty – and potent – Quaker State Heavyweight.

Conversations about birds during the first half of the tour rapidly turned to conversations about beer, often spurred on by discussions about the samples, and several people remarked how these beers were outside of their usual comfort zone, broadening their horizons and challenging their pallets. One could say there is a parallel to our discussions about the finer point of “peep” identification while out in the marsh!

It seemed most appropriate that our second brewery of the tour would be Rising Tide Brewing in Portland – our partner in the Birds on Tap! lecture series. Refreshing Daymark, a clean and classic APA; Ishmael, the rich and malty American copper ale; Zephyr, Rising Tide’s hoppy but incredibly well-balanced IPA; and of course, the venerable Maine Island Trail Ale the citrusy, hoppy, and summertime-perfect American Ale that is one of the favorite beers of many a Maine beer drinker, myself included.


While many of the Maine residents in the group – we also had guests from Kansas and folks who share Maine with another home state – were more familiar with the offerings of this favorite brewery, Alex did a great job explaining the philosophy of the brewery and the methods they use to produce so many quality, unique, – and in many cases, exceedingly approachable – brews.

As we wrapped things up and Josh transported us back to our respective drop-offs, the bus was filled with chatter about birds, beers, and more than one question for when the next Birds on Tap – Roadtrip! from Freeport Wild Bird Supply and the Maine Brew Bus will be taking place…stay tuned!
