This Week’s (Plus) Highlights and Shorebird High Counts, 8/19 – 8/28/2025

For the last 13 summers now, hybrid herons have occurred in Scarborough Marsh, with one individual continuing this summer. Likely also present last summer, this bird is significantly darker on the neck and back than the only bird present from about 2021 to 2023, possibly suggesting yet another backcross (Gen 4?) with Tricolored Heron (especially when observed with its breeding plumes earlier in the summer). It does appear quite similar to my proposed 2nd or 3erd generation Tricolored Heron x Snowy Egret x Little Egret that was present from 2016 to at least 2020, so it could possibly by the same bird (Labeled 3A in my article Hybrid Herons of Maine from my North American Birds article in 2021, Volume 72, Number 3. At this point, I believe the hybrids are best described as “Tricolored Heron x small white Egretta species,” or, “Patches” as I dubbed it and most birders refer to it now. Whatever it is, this year’s individual cooperated for me along the Eastern Road Trail on the 26th.

It was another busy period for me, with most of my mornings spent only birding our property before work. Luckily, the yard has been fantastic as it turns out to be this time of year, with a nice variety of migrants, and lots of local breeders fattening up on our plentiful Black Cherry trees. Some of the migrants detected this week included a Prairie Warbler on 8/19, a Swainson’s Thrush on 8/20, Canada Warbler on 8/21, Cape May Warbler 8/24-25, a single Common Nighthawk at dusk on 8/26, and a BLUE-GRAY GNATCATCHER on 8/27.

Otherwise, it was a weekend trip to Bar Harbor and a shorebird little-big day on the 26th that kept me going, with the following observations of note over the past 10 days.

  • 1 continuing COMMON GALLINULE, Essex Marsh, Bangor, 8/22 (with Bill Thompson).
  • The big adventure this week was the 12-hour pelagic/whale watch out of Bar Harbor with Flukes and Bar Harbor Whale Watch Co to Cashes Ledge in the Gulf of Maine. I’ll leave the complete checklist to others, but my highlights from the trip were the total of 33* Leach’s Storm-Petrels, repeated great view of a total of 15* Pomarine Jaegers, the feeding frenzy of Wilson’s Storm-Petrels (day total of 1,573*) at Ammen Ledge, and the scattered flocks of Red-necked Phalaropes.

  • 2 FORSTER’S TERNS, The Pool, Biddeford Pool, 8/26.
  • 2-3 continuing adult RED-NECKED GREBES, Ocean Avenue, Biddeford Pool, 8/26.

*Official trip tallies kept by others, although my personal numbers would likely have been similar.

This Week’s Highlights and Shorebird High Counts, 7/28 – 8/8/2025

One of two Baird’s Sandpipers that were in the salt pannes of the Eastern Road Trail through Scarborough Marsh on the 7th, it was one of an estimated 3500+ shorebirds present that day. Low water conditions are currently ideal, but they are drying out fast, and without some rain in the next week, this hotspot might just become too dry to hold many birds.  

With a busy few days of catching up, my birding was limited immediately upon our return from our summer vacation. However, I made up for it this week with a couple of tours and two birding outings with friends. There is a surprising number and quality of summertime rarities around the state right now, but I stayed fairly local and tried to find my own rare shorebird or two! Here are my observations of note over the past 12 days here in Maine.

  • A vocal Yellow-billed Cuckoo continues daily in our yard all week.
  • 1 Great Egret, flying over downtown Waterville at dusk, 7/28 (with Jeannette).
  • 2 Long-tailed Ducks, Simpson’s Point, Brunswick, 8/1.
  • 1 TRICOLORED HERON (FOY), Pelreco Marsh, Scarborough Marsh, 8/3 (with Birds on Tap – Roadtrip! Tour Group). Photo in trip report here.
  • 3 adult RED-NECKED GREBES, 1 White-winged Scoter, and 1 Black Scoter, Ocean Avenue-Biddeford Pool Beach, Biddeford, 8/5 (with Bill Thompson)
  • 1 female PURPLE MARTIN, Timber Point, Biddeford, 8/5 (with Bill Thompson). Confirmed breeding as it entered a powerline visual marker ball with food and exited with a fecal sac!
  • PATCHES! Perhaps Patches the IVth? Presumed TRICOLORED HERON X SNOWY EGRET X LITTLE EGRET HYBRID that now may be a fourth-generation bird that’s a backcross again with a TRICOLORED HERON as this year’s bird has significantly more bluish color than previous years, and in all the right places for a Tricolored. In other words, “Tricolored Heron x Small White Egretta SPP”, or, “Patches.” But the hybrid heron was in the salt pannes of the Eastern Road Trail on 8/7 (with Ian Doherty). My phone-scoped photos in the heat shimmer don’t do it justice!
  • 7 Bonaparte’s Gulls, Sabattus Pond, 8/8.

And as expected for the season, shorebird migration is now in full swing and that was the focus of my birding attention, resulting in a solid 21 species. Here were my high counts over these past 12 days:

  • American Oystercatcher: 7 (4 ad, 3 juv), Hill’s Beach, Biddeford, 8/5 (with Bill Thompson).
  • Black-bellied Plover: 60+, The Pool, Biddeford Pool, 8/5 (with Bill Thompson).
  • Killdeer: 11, Sabattus Pond, 8/8.
  • Semipalmated Plover: 375, Hill’s Beach, 8/5 (with Bill Thompson).
  • Whimbrel: 3, Pine Point, Scarborough, 8/3 (with Birds on Tap – Roadtrip! Tour Group).
  • Ruddy Turnstone: 5, Ocean Avenue, Biddeford Pool, 8/5 (with Bill Thompson).
  • Red Knot (FOF): 1 ad, Hill’s Beach, 8/5 (with Bill Thompson).
  • Sanderling: 2, Hill’s Beach, Biddeford, 8/5 (with Bill Thompson).
  • BAIRD’S SANDPIPER (FOY): 2, Eastern Road Trail Scarborough Marsh, 8/7 (with Ian Doherty). Photo above.
  • Least Sandpiper: 350+, Eastern Road Trail, Scarborough Marsh, 8/7 (with Ian Doherty).
  • White-rumped Sandpiper: 75+ (wow! Great count!), Eastern Road Trail, 8/7 (with Ian Doherty).
  • Pectoral Sandpiper: 1, Eastern Road Trail, 8/7 (with Ian Doherty).
  • Semipalmated Sandpiper: Incredible concentration of 2750-3000+ at Eastern Road Trail, 8/7 (with Ian Doherty), but an honorable mention of 2500+ at Pine Point, Scarborough, 8/3 (with Birds on Tap – Roadtrip! Tour Group).
  • WESTERN SANDPIPER (FOY): 1 ad, Eastern Road Trail, 8/7 (with Ian Doherty).
  • Short-billed Dowitcher: 58, Hill’s Beach, 8/5 (with Bill Thompson).
  • American Woodcock: 2, our property in Durham, 8/1.
  • Spotted Sandpiper: 2, several locations this week.
  • Solitary Sandpiper: 1, Moosehorn NWR – Baring Division, 7/28 (with Jeannette) and Sabattus Pond, 8/8.
  • Lesser Yellowlegs: 104, Walsh Preserve, Freeport, 8/2 (with Saturday Morning Birdwalk group).
  • “Eastern” Willet: 22, The Pool, Biddeford, 8/5 (with Bill Thompson).
  • Greater Yellowlegs: 12, Wharton Point, Brunswick, 8/1.

UPCOMING TOURS w/ Space Available:

Shorebird Workshop with Down East Adventures, August 18th, 8:00am to 4:00pm.

 Recent Highlights, 7/10 – 7/21/2024

This Tropical Kingbird, a long-overdue third state record, was discovered at the Skelton Dam Boat Launch in Dayton. Many of us saw it on the morning of 7/18, but it may have been present for nearly three weeks before being identified!

It’s been a busy 12 days, with a weekend in Quebec City and summertime human visitors. Of course, the last day in Quebec City was when the Ferruginous Hawk was 20 minutes from our home. Oh well…brunch was absolutely fantastic. Sadly, life and work minimized my birding during this period, despite a suite of rarities now appearing around the Northeast.  Luckily, I did have a couple of good mornings in the field before we head out on our summer vacation, including hours of quality time with a Tropical Kingbird in Dayton that was happily identified while I was around and somehow free of responsibilities for the morning!  I wonder what will show up while we are gone this time!?

  • Both Yellow-billed and Black-billed Cuckoos have been calling on our Durham property all week.
  • 1+ WHITE-WINGED CROSSBILL, Moore’s Pond, Bradstreet Twp, 7/12 (with Jeannette).
  • 2-3 Grasshopper Sparrows, Auburn-Lewiston Municipal Airport, Auburn, 7/15 (with Doug Hitchcox et all).
  • 1 continuing TROPICAL KINGBIRD, Skelton Dam Boat Launch, Dayton, 7/18 (with m’obs). Third state record, first chase-able. Long overdue state bird for me! After years of expecting, predicting, and looking for one, in my frustration, I pulled it off my “Next 25 Predictions List” and so I don’t get any credit for this one. I still enjoyed it though. Photo above, and video here: https://www.facebook.com/share/v/4qyGf1VSmw1wpSon/
  • The salt pannes along the Eastern Road Trail in Scarborough Marsh are exceptional right now due to low water levels. On the morning of the 19th, a few of the tallies included 125+ Snowy and 50+ Great Egrets; 50+ Glossy Ibis; and 20+ Great Blue Herons. Shorebird numbers included a nice number of Least and Semipalmated Sandpipers; 50+ Greater and 30+ Lesser Yellowlegs; 16 Short-billed Dowitchers; and 2 Pectoral Sandpipers (FOF). Of course the highlight for me, however, was “Patches Jr, Jr” – the proposed HYBRID TRICOLORED HERON x SMALL WHITE EGRET(S) SPP back for another year. In fact, it’s already year 12 of this complex here. Unfortunately, it was too far for photos today.  For more information, see: North American Birds, Volume 72: No 2, pp 28-40.
  • 1 Yellow-throated Vireo, our property in Durham, 7/21. Yard Bird #153!

Tours and Events:

  • There will not be a Saturday Morning Birdwalk on 7/27.

This Week’s Highlights, 6/16-23, 2023

It’s always exciting to show a tour a one-of-a-kind bird that is found no where else in the world (that we know of!). And “Patches III” the proposed Tricolored Heron x Snowy Egret x Snowy Egret hybrid (I think…maybe) put on quite a show for us on the third day of the tour.

I just finished up a whirlwind 9-day tour with my good friend Scott Barnes for New Jersey Audubon. I’ll be sorting photos for a while and will post more later, but our unexpected observations of note while traveling around Maine (with about 24 hours in New Hampshire and a few hours in New Brunswick) besides all of our wonderful breeding birds, included the following:

  • 1 Yellow-billed Cuckoo (FOY, surprisingly), Brownfield Bog, Brownfield, 6/16.
  • 1 White-rumped Sandpiper, Eastern Road Trail, Scarborough Marsh, 6/18.
  • 1 continuing proposed TRICOLORED HERON X SNOWY EGRET X SNOWY EGRET hybrid (aka “Patches III”), Pelreco Marsh, Scarborough Marsh, 6/18 (photo above).
  • 1 drake Northern Pintail, Pelreco Marsh, 6/18.
  • 1 continuing drake KING EIDER, 3 adult RED-NECKED GREBES (including a pair doing a little light courting), and an impressive 72 Black Scoters, Ocean Avenue, Biddeford Pool, 6/18.
  • 1 pair ORCHARD ORIOLES and one late singing Wilson’s Warbler, Capisic Pond Park, 6/19.
  • 1 pair Sandhill Cranes, Messalonskee Lake, 6/19.
  • 1 Yellow-bellied Flycatcher, 1 Red-breasted Nuthatch, and 1 Indigo Bunting, Machias Seal Island, 6/20.
  • 1 MANX SHEARWATER, between Machias Seal Island and Cutler Harbor, 6/20.
  • Scattered Red Crossbills around Washington County.
  • 80+ Razorbills and 12 Surf Scoters, Quoddy Head State Park, 6/21.
  • 1 family group of CANADA JAYS, Wesley Township, 6/22.
  • 4 Black-bellied Plovers, Petit Manan NWR – Hollingsworth Trail, 6/22.
  • 2 American Oystercatchers, Egg Rock, Frenchman Bay, 6/23 (with Bar Harbor Whale Watch Co).
  • 2 American Oystercatchers and 2 Common Murres, Petit Manan Island, 6/23 (with Bar Harbor Whale Watch Company).
  • 1 LEACH’S STORM-PETREL, 1 BLACK-LEGGED KITTIWAKE, 1 Sooty Shearwater (FOY), 25+ Great Shearwaters, etc, off Bar Harbor with Bar Harbor Whale Watch Co).
  • 5+ Black Terns, Plymouth Pond, 6/24.

This Week’s Highlights, 1/29-2/6, 2022

While not the rarest bird this week, I have been thoroughly entertained by this Brown Creeper who has taken to picking up bits of seed from under a feeder at our home in Pownal. The horizontal position makes the bird look so different! Sorry for the lousy photos though…they were taken through a screen during the ice/snow storm on 2/4.

The Blizzard of 2022 provided some great opportunities for cross-country skiing and snowshoeing locally for the first time this winter, so I took full advantage of that, even if it did further limit my dedicated birding during this busy week plus.  Interestingly, my most “serious” birding was a half day (post-snowblowing and shoveling) on Sunday searching Portland through Cape Elizabeth for storm-related birds, but that effort turned up nothing at all of note! Here are my observations of note over the past 9 days:

  • 5 WHITE-WINGED CROSSBILLS, 2 COMMON REDPOLLS (FOY), 6 Pine Siskins (FOY), and 1 Purple Finch, Long Falls Dam Road area of Carrying Place Township, 1/31 (with Jeannette).
  • The Androscoggin River between the downtowns of Lewiston and Auburn remain a surprisingly productive mid-winter hotspot. On 2/1, Jeannette and I discovered an incredible (especially for the interior of Maine) five species of dabblers from the Auburn Riverwalk!  Amongst the Mallards and a couple of American Black Ducks, there were single female GREEN-WINGED TEAL, AMERICAN WIGEON, and NORTHERN PINTAIL.  Making this even more interesting is the fact that it’s usually the drakes that we find overwintering in Maine.  Additionally, the drake RING-NECKED DUCK continues, and we had a single 1st-winter Iceland Gull. Two Bufflehead and 5 Hooded Mergansers joined the usual Common Goldeneyes and Common Mergansers for a goodly inland total of 10 species of waterfowl. A unusually conspicuous Beaver continues to amuse here as well.
  • 3 drake and 1 hen BARROW’S GOLDENEYES and 8 Dunlin (FOW here), Winslow Park, Freeport, 2/13.

Other Notes:

  • My article – a 13-page photo salon – on the Hybrid Herons of Scarborough Marsh (Patches!) has finally been published in the most recent issue of North American Birds. In it, I lay out the theory that at least 5 different individuals have been seen in Scarborough Marsh since I first found an odd juvenile heron in July of 2012 that we now believe is a hybrid between a Snowy Egret and a Tricolored Heron.

I made the case that the two current birds are backcrosses, one with a Snowy Egret (SNEG X TRHE X SNEG) and the other with a Little Egret (SNEG X TRHE X LIEG). I’ll be watching them carefully for the potential of a developing hybrid swarm.

Unfortunately, at this time, the journal is only available online to members of the ABA. However, digital e-memberships (with access to all of the ABA publications) are only $30 a year, and you can purchase issues of the magazine directly from the ABA by emailing info@aba.org. Also, if you wanted to take a peek at the article, I do have a couple of extra copies here at the store for you to peruse.

Believe it or not, a hybrid heron is much rarer than a Steller’s Sea-Eagle, at least from a world perspective…in fact, it’s possible these birds are one of a kind!

Derek’s Birding This Week: 8/28-9/3, 2021

  • “Eastern” Willet: 8, Pine Point, 8/29.
  • Greater Yellowlegs: 11, Eastern Road Trail, 9/3.

Derek’s Birding This Week, 5/15-21/2021

 

In an article to be published this fall in the journal North American Birds, I propose this bird as a Tricolored Heron x Snowy Egret hybrid backcrossed with a Little Egret (TRHE x SNEG x LIEG). This individual has been present since 2014 and seems to visit marshes between Hampton, NH and Cape Elizabeth. Note the two long neck plumes and the greenish lores.

My highlights over the past seven days included the following:

  • 58 White-winged Scoters, Bradbury Mountain Hawkwatch, 5/15.

This Saltmarsh Sparrow posed for a quick photo this morning along the Eastern Road Trail. My first of the year were today, although at least a few have likely been present for a week to 10 days in and around Scarborough Marsh.

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!

3. EasternRoadTrail_group

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!
