The Two “Shorebirds and Beer” Birds on Tap – Roadtrips of 2016

1. Brew_Bus_store_from_Stacey_edited-1

“Shorebirds and Beer” was our first-ever “Birds on Tap – Roadtrip!” in partnership with our friends at The Maine Brew Bus last August. Now our 6th trip together, combining casual yet instructive birding in some of the state’s best seasonal hotspots with visits to two of our fantastic local breweries, we planned a return to Scarborough Marsh – where it all began!

And by popular demand, we added a second date. So this year, we had two “Shorebirds and Beer” departures, on August 7th and again on August 14th.  Both visited Scarborough Marsh, focusing our efforts on migratory shorebirds, but combined pairs of very different breweries.

We began the August 7th visit to Scarborough Marsh at the Eastern Road Trail.  A nice variety of birds were observed, including a couple of very cooperative singing Nelson’s Sparrows. Unfortunately, we found our destination, the salt pannes on the northern side of the marsh to be completely bone-dry due to this year’s drought. Needless to say, the numbers of shorebirds were not what we were hoping for. In fact, other than a few small groups of Least Sandpipers popping in and out of the grass, the pannes – often the most productive place in the entire marsh at this season – were completely devoid of shorebirds!

However, along the road, we had some good instructive lessons, including ultra-cooperative Least Sandpipers than began our introduction into shorebird identification. We learned how breaking shorebirds down into family by shape and size first narrows the choices, and allows you to focus on just a few species to identify. We even had a perfect example of this, when three members of the genus Tringa were standing side-by-side as a dainty Lesser Yellowlegs joined a couple of Greater Yellowlegs while a bulky Tringa-on-steroids, Willet (of the Eastern subspecies, for the record) looked on.

Heading over to Pine Point as the tide rapidly rolled in, various human disturbances in Jones Creek limited shorebird diversity, but we could not have asked for more cooperative Semipalmated Sandpipers and Semipalmated Plovers (about 200 and 100, respectively) that really allowed us to practice our plover vs. sandpiper feeding shape and style dichotomy.

We then moved on to work on specific identification.

The remainder of our birding time was spent scanning the last of the distance sandbars (adding Black-bellied Plover to the shorebird checklist), before one of the members of the group called me over to check out an odd bird she found in her scope. It was an American Avocet!

While distance and heat shimmer precluded documentation photos, everyone was treated to a look or two in the scope of this very rare-in-Maine bird that isn’t seen every year anywhere in the state. While the long, fine bill was barely discernable at the distance, the very long legs and overall tall size (compared to nearby gulls) coupled with the distinctive tri-colored appearance (buffy head and neck, white underparts, and black wing with a broad white stripe) looks like no other.

And then it was time for a celebratory beer!  After a celebratory hand-pie for lunch, of course.

First up was Barreled Souls in Saco, the only brewery in the country that is producing 100% barrel fermented beer in their Burton-Union system. Producing a mere 400 barrels a year – yet still offering 10-12 brews on tap at all times! – this time-consuming process which included two stages of fermentation, allows for the creation of some very complex beers.

Our samples today began with Half-Shilling, a very-light-bodied and low-ABV Scotch Ale as an introduction. Rosalita followed, using agave nectar in the primary fermentation and then steeped with hibiscus flowers during secondary fermentation, making for a very floral and subtly-sweet brew.  Space Gose was next, a summer refresher made with Maine sea salt, lemon zest, and coriander. By request, we then did a complete beer-wise-180 and shifted over to a heavy Barrel-aged MCAM – a very unique breakfast porter made with cinnamon, French toast, and bacon!  The spice, sweet, and smokiness were evident, as were the hints of bourbon from the bourbon barrels it was aged in. It was a potent, and very tasty, beer and a good representation of Barreled Souls’ creativity.

Our final destination of the day was Lone Pine Brewing in Portland. We began with their flagship Portland Pale Ale, using 90% Aroostook County-grown malts. This is a really great pale, with lots of flavor but incredibly smooth and lacking bitterness. Pale ales are occasionally “boring” to those who like a lot of hops, but this exceedingly well-balanced beer could be a new go-to for quite a few of us on the tour.

Their new Brightside IPA was next on our agenda, and I would put this right up there with the best IPAs in the state. Bright and citrusy, yet without that overwhelming bitterness that often pervades stronger IPAs (this one clocks in at a potent 7% alcohol), it may be way too easy-drinking. It was also a very “accessible” IPA for the non-hopheads. One member of group in particular, who normally doesn’t like IPAs at all, was actually quite a fan of this also well-balanced beer. For me, a sign of a truly great beer is one that is so good is that it appeals to those who normally don’t like that particular style.

The following weekend, we once again began our birding at Eastern Road. Despite some rain in the past few days, however, the salt pannes were still dry. But to and fro, we encountered a nice mix of shorebirds, including some unbelievable cooperative Least Sandpipers once again.

This one was phone-binned (a photo taken with an iPhone through my binoculars)!

Three Spotted Sandpipers – our first shorebirds of the day, actually – were encountered as we began our walk, and a decent number of Semipalmated Sandpipers were in the dried pannes. Both Lesser and Greater Yellowlegs were seen together for instructive studies. A distant hunting Northern Harrier, more singing (but this week, not seen) Nelson’s Sparrows, and lots of Cedar Waxwings and Song Sparrows foraging in the trailside scrub were among the highlights. We also took the time to watch Common Wood-Nymph butterflies, Great and Snowy Egrets, and stopped to enjoy the magnificently beautiful color of the eyes of Double-crested Cormorants.

On the walk back, with the tide just starting to recede, we had the opportunity to check out a few Semipalmated Plovers, Semipalmated Sandpipers, and a Least Sandpiper all side-by-side, just about 20 feet away.

A quick stop at the Pelreco marsh produced yet more Least Sandpipers, a better view of the details of Greater Yellowlegs, two spiffy adult Little Blue Herons, and most importantly: Patches! Arguably one of the rarest birds in the world, this Tricolored Heron x Snowy Egret hybrid that has been frequenting the marsh for the past 3 years put on quite a show for us. It could – hypothetically – be the only one of its kind!

Thanks to a change in brewery itinerary for this second run of “Shorebirds and Beer,” I was able to stall at the marsh long enough to allow enough water to flow out that mud was rapidly being exposed at Pine Point. And with it, excellent numbers of all of the expected shorebirds began to appear: 400+ Semipalmated Sandpipers, 300+ Semipalmated Plovers, 150+ Black-bellied Plovers, 22 Short-billed Dowitchers, 8 “Eastern” Willets, 6 White-rumped Sandpipers, 4 Ruddy Turnstones, a few Least Sandpipers, and 2 Greater Yellowlegs.

No American Avocet though, but a hunting Peregrine Falcon zipped through, causing quite the ruckus.

And then it was once again beer o’clock, and today we began our beer-ing tour with a visit to South Portland’s Foulmouthed Brewing. Only open for 7 weeks, it was a new destination for everyone on today’s tour – myself included – and we learned all about the owners, the fledgling (see what I did there?) brewpub (yup, they opened a restaurant too), and their wide range of beers.  We even enjoyed a not-quite-ready-for-prime-time sample of their new “Blue Balls,” a Belgian dark, strong beer with blueberries. Still a week or two from being finished, it was a great introduction to their creative brewing side.

Inside at the brewpub, we sat at the big kids’ table and sampled four of their current offerings. Beginning with Brat, a German-style session with its bright and clean Noble hop finish, we moved onto Half Wit, a “hybrid” (not of heron and egret, mind you) of a Belgian Wit and an American Pale. A favorite of many on today’s visit, it was smooth and accessible, with enough body and flavor to hold its own. Kaizen Saison was up next, with its rotating hops producing a different flavor and aroma profile with each batch. We finished up with Rhubarb de Garde, a strong amber aged on rhubarb. I found a little extra sweetness and especially just the hint of tart from the rhubarb complimented each other nicely.

Our final beer stop of the day was a return trip to Lone Pine Brewing. Tom once again took us through their methods and philosophy, and shared with us their Portland Pale Ale and Brightside IPA. The more I drink the Portland Pale, the more I love this perfectly balanced beer.

While Don, always attentive, looked like he had just spotted a Blue-footed Booby.

With our final sips of Brightside, the second installment of Shorebirds and Beer came to a close and it was time to head back home. Every day is different during the window of shorebird migration, and these two visits to Scarborough Marsh exemplified that. A wide range of shorebirds were studied, as we started to expand our identification – and appreciation – toolbox. And between Barreled Souls, Lone Pine, and Foulmouthed, we were exposed to a wide range of beer styles and methodologies.

And both are the goals of our Birds on Tap – Roadtrip! series: exposure to some of our seasonal birding highlights and our vast array of fantastic local breweries. We hope you’ll join us for our next roadtrip, on October 9th, when we head to the deep south to visit Kittery’s Fort Foster and Seapoint Beach for our birding, and Tributary and Hidden Cove Brewing for our beering. Hope to see you then!

Shorebird Pseudo-Big Day

Luke Seitz and I embarked on a semi-serious “Shorebird Big Day” on Wednesday.  I say “semi-serious” because we didn’t exactly try too hard to build our list…at least not after our first stop.  Instead, we spent more time watching shorebirds, studying, and photographing them.  We still, however, tallied 14 species of shorebirds, but instead of heading inland to pick up Killdeer, Spotted Sandpiper, Solitary Sandpiper, and Upland Sandpiper, we just splashed in the water and studied dowitchers at Hill’s Beach.  It wasn’t a bad way to spend a gorgeous summer day.

We began in the morning at high tide by scouring Scarborough Marsh from the Eastern Road Trail.  If we were to have a chance at 20 species of shorebirds on the day, we would need to add a rarity or two from the pannes.  Unfortunately, high water levels from all of the recent rain minimized habitat, and shorebirds were not as plentiful as we would have preferred.  We did, however, see 2 or 3 Stilt Sandpipers, a decent bird in the summer.  Other than Greater Yellowlegs, with about 55 individuals, numbers were relatively low: 75 Semipalmated Sandpipers, 40 Short-billed Dowitchers, 25+ Least Sandpipers, 8 Lesser Yellowlegs, 3 Black-bellied Plovers, 2 Semipalmated Plovers, and 1 Willet.

Making up for the low shorebird totals, however, were the high wading bird totals: 85 Snowy Egrets, 60 Great Egrets, 40 Glossy Ibis, 39 Little Blue Herons, and 9 Great Blue Herons.  In addition to teasing out one of the continuing White-faced Ibises and spotting the continuing full Tricolored Heron, we also saw BOTH of the presumed Tricolored Heron x Snowy Egret hybrids.  Yup, there are two of these beasties out there!

The first is the bird that has been present all summer, with a ghostly cast to an otherwise Tricolored-like pattern.  Pure white is confined to the belly, the throat, and a thin line in the foreneck.

However, recently, a second bird has appeared, which is very reminiscent of the first, but has some splotchy areas of white, including mostly white wingtips.  I believe I saw this bird on July 18th when I was out with a client and sans camera; I remember commenting (and my field notes confirm) that I didn’t remember so much white in the wing

Meanwhile, it was nice to see that at least one of the White-faced Ibises continue, although at this stage of molt, it was impossible to age.  It was also not very close.  Here’s Luke’s best shot (mine were not passable at all).

After spending more time with waders and a little time of sparrows, such as this Nelson’s Sparrow…
NESP,EasternRd,7-31-13_edited-1

…we attempted to regain our shorebird focus over at Pine Point, as the tide was rolling out.  The mudflats had plenty of birds, including a few birds that would be important for a Shorebird Big Day, such as the pair – now, featuring two fledglings! – of American Oystercatchers (the only breeding pair in the state!).  We also had four Whimbrel, along with 296 Semipalmated Sandpipers, 124 Semipalmated Plovers, 25 Willets, 25 Short-billed Dowitchers, 19 Black-bellied Plovers, 3 Ruddy Turnstones, and 2 each of Lesser and Greater Yellowlegs.

But with a morning total of a mere 11 species of shorebirds, we elected for a leisurely lunch at Saco Island Deli instead of heading inland to work on our shorebird list – it is really too early in the season for a true Shorebird Big Day, but I am not sure if I have ever hit 20 in July, and since this was a day we both had a chance to get out all day together, we figured it was at least worth considering.  Anyway, on the incoming tide, we visited Hill’s Beach, where once again, we elected to forego shorebird listing for shorebird “quality” time, and therefore just spent close to three hours playing in the sand.

While the two Red Knots…
DSC_0175_REKN1,HillsBeach,7-31-13_edited-1

…4 Piping Plovers (a pair fledged two young here for the first time in recent memory), and 8 Sanderlings brought our count to 14 species on the day, we became distracted by photographing terns and studying dowitchers.  While our goodly count of 155 Semipalmated Plovers were augmented by about 65 Semipalmated Sandpipers, 8 Black-bellied Plovers, 4 Ruddy Turnstones, and 1 Least Sandpiper, it was the 120 or so Short-billed Dowitchers that kept our attention.

We were looking for individuals of the interior subspecies hendersonii, as I did on Sunday with Phil. (See blog and photos here:

https://mebirdingfieldnotes.wordpress.com/2013/07/28/biddeford-in-shorebird-season/).  We had what was possibly the same bright bird as Sunday (see above) fly-by, it was the paler birds that had us intrigued.
Luke on Hills, 7-31-13_edited-2

We thought the combination of a bright orange chest, and a fair amount of orange between the legs and on the undertail coverts, compared with the paler face and lightly, but distinctly spotted flanks and side (especially the side of the breast) of this bird made it look “good.”
DSC_0234_HendersoniiSBDO-pale,HillsBeach,7-31-13_edited-1

But we were pondering how extensive of color a hendersonii “needs” to have, as most of the individuals of the expected Eastern subspecies griseus, also were showing at least a touch of peachy-orange color in the undertail, etc.
DSC_0254_SBDOs,HillsBeach,7-31-13_edited-1

Here are some typical, and typically variable, griseus for comparison.

In the end, we simply said, “who knows!?”  and went back to photographing other fun stuff, such as this Bonaparte’s Gull…
DSC_0228_BOGU_HillsBeach,7-31-13_edited-1

And this juvenile Roseate Tern…which was actually one of my targets to photograph today.
DSC_0218_ROST-juv1,HillsBeach,7-31-13_edited-1

Ok, so we really quit on the Big Day attempt by about 10:33 in the morning, but 14 species of shorebirds included Stilt Sandpiper, American Oystercatcher, and two hendersonii Short-billed Dowitcher, along with two Tricolored Heron x Snowy Egret hybrids, White-faced Ibis, Tricolored Heron, a mid-summer marsh Merlin (these birds have simply got to be breeding in coastal Cumberland County!), it was hardly a bad day of birding.  In fact, it was actually a spectacular day!
