 This Week’s Highlights 8/3– 8/12/2026.

The last of the locally-breeding Roseate Terns have been been putting on quite a show around Pine Point, including this one that still showed a mostly all-black bill.

Jeannette and I returned from our summer vacation on the 3rd, and with shorebird migration in full swing, so I went right back to work, both personally and professionally! Here are my observations of note over the past 10 days:

  • 1 Blue-gray Gnatcatcher has been present in our Durham yard since 8/8.
  • 3 Gadwall, Walsh Preserve, Freeport, 8/4.
  • 1 Louisiana Waterthrush, River Winds Farm and Estate (Private), Saco, 8/5.
  • 1 juvenile Little Blue Heron, Walsh Preserve, Freeport, 8/8 (with Saturday Morning Birdwalk group).
  • 3 continuing FORSTER’S TERNS, Great Pond, Biddeford Pool, 8/9 (with Down East Magazine Shorebird Workshop tour group).
  • 1 continuing THICK-BILLED MURRE, Ferry/Western Beach, Scarborough, 8/10 (with Jeannette). Present since 7/18, this first summer bird is in heavy wing molt, but otherwise appears healthy, actively diving, and surviving just fine. Please, just give it some room! We have been monitoring its health in consultation with Avian Haven, but even though it is well south of normal summertime range and it’s standing on the beach, it appears absolutely fine. Murres cannot take off from flat land, plus it’s in heavy molt, so perceptions of it being “sick” are just well-intentioned misunderstanding. It is being monitored, however!

  • 1 continuing TRICOLORED HERON, Eastern Road Trail, Scarborough Marsh, 8/10 (with Jeannette).
  • 1 continuing “PATCHES!” the proposed TRICOLORED HERON X SMALL WHITE EGRETTA(S) HYBIRD. This seems to be the same individual present since at least 2023. Discussion and great photos from Bill Thompson can be seen here.

Prior to our trip, I had a couple of notable observations in the two days after my last post before we departed :

  • 1 Yellow-billed Cuckoo (FOY, finally) and 1 Blue-gray Gnatcatcher, Old Town House Park, 7/25 (with Saturday Morning Birdwalk group).
  • Highlights from my 7/26 “Whale Watch and Puffin Combo” birder’s special tour with Cap’n Fish’s Cruises out of Boothbay Harbor included: 206 Wilson’s Storm-Petrels, 16 RED-NECKED PHALAROPES, 3-4 RED PHALAROPES (upon photo review), a mere one Great Shearwater, 1 Northern Gannet, and of course all three terns and a great Atlantic Puffin show (especially for the date) at Eastern Egg Rock.

And here are my shorebird high counts over the past 10 days (see previous blog for an explanation of the “data” included here):

  • AMERICAN OYSTERCATCHER: 8, Hill’s Beach, Biddeford, 8/9 (with Down East Magazine Shorebird Workshop tour group).

Upcoming Tours (that have space):

Birds on Tap℠ – Roadtrip! Shorebirds and Steins

August 16, 2026; 9:00am – 3:00pm​

These unique, relaxed birding and beer-ing adventures that you have come to love combine great local birding at seasonal hotspots with visits to sample the delicious creations of some of our favorite local breweries. These tours are a perfect introduction to birding and/or craft beer, and a great opportunity to travel with significant others, friends, and family that have interest in one topic, while your interest is primarily in the other (for now!). Seasonal birding hotspots and great local beer – a perfect combination, and we’ll even do all of the driving!

The original BoT Roadtrip! Way back in 2015, our most popular tour returns to Scarborough Marsh at prime time for a good variety of migrant shorebirds. We’ll learn how to identify our common species, and search for the rare. Up to 20 species of shorebirds are possible! We’ll practice identifying our “peeps” (Least, Semipalmated, and White-rumped Sandpipers) and attempt to tease out a rare Western or even a Baird’s among the masses. We’ll look for local breeding American Oystercatchers and Willets, while searching for migrants such as Red Knots on their way from the high Arctic to the southern tip of Argentina.

Juvenile Little Blue Heron, Scarborough Marsh, 8/10.

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.

Pomarine Jaeger (above) and Great Shearwater (below)

  • 2 Horned Grebes (oversummering or really early?) and 2 Red Crossbills, Hollingsworth Trail, Petit Manan NWR, Steuben, 8/24 (with Bill Thompson).
  • 2 FORSTER’S TERNS, The Pool, Biddeford Pool, 8/26.
  • 2-3 continuing adult RED-NECKED GREBES, Ocean Avenue, Biddeford Pool, 8/26.
  • 1 continuing postulated TRICOLORED HERON X SMALL WHITE EGRETTA SPP, aka “Patches,” Eastern Road Trail, Scarborough Marsh, 8/26. Photo and notes above.

Fueled by a 19 shorebird species day on the 26th, I tallied 22 species of shorebirds this week, with my high counts over these past 10 days (see last week’s post for explanation) being the following:

  • American Oystercatcher: 7 (4 ad, 3 juv), Hill’s Beach, Biddeford, 8/26 (with Noah Gibb and Stacey Huth).
  • Black-bellied Plover: 156, The Pool, Biddeford Pool, 8/26.
  • Killdeer: 46, Crystal Spring Farm, Brunswick, 8/25.
  • Semipalmated Plover: 150+, Eastern Road Trail, Scarborough Marsh, 8/26.
  • Piping Plover: 15, Hill’s Beach, Biddeford, 8/26 (With Noah Gibb and Stacey Huth).

  • Ruddy Turnstone: 12*, Mt Desert Rock via Cashes Ledge boat trip, 8/23.
  • Red Knot: 8, The Pool, 8/26 and 3, Wharton Point, Brunswick, 8/25.
  • Sanderling: 5, Hill’s Beach, 8/26.
  • Dunlin: 1 adult, Wharton Point, 8/25 (early).
  • Least Sandpiper: 98, Eastern Road Trail, 8/26.

  • Solitary Sandpiper: 1, Rte 136, Durham, 8/26.
  • Lesser Yellowlegs: 19, Eastern Road Trail, 8/26.
  • “Eastern” Willet: 8, The Pool, 8/26.
  • Greater Yellowlegs: 41, Wharton Point, 8/25.
  • RED-NECKED PHALAROPE: 218*, Cashes Ledge boat trip, 8/23.
  • RED PHALAROPE: 1* but I had at least 3 more, Cash’s Ledge boat trip, 8/23.

*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).

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!

Three Days at Florida Lake Park

IMG_4214-edited-edited
Northern Parula

One of my favorite aspects of May is that there are “new” birds every day. Constant turnover as the flow of migratory songbirds, especially the long-distance Neotropical migrants, reaches its peak means “first-of-years” can be found almost every day. Even better, is the constant turnover and new arrivals almost anywhere we go birding.

…Including at local patches. And for me, there are few places I’d rather be than staying near home at Florida Lake Park in Freeport. I can get in several hours of birding and still make it to work in time, which is important in one of our store’s two busiest months. We’re luck to have this park only 12 minutes from our house, which makes for a perfect birding “patch.”

Blackburnian Warbler

With an exceptionally busy week, my birding time was limited to the early mornings, but Florida Lake did not let me down. In fact, it was a lot of fun. With good diversity each day, and new birds arriving each night, there was always something new to look at. And, as is the case with loyal patch-working, the consistency of visitation makes for a nice education on the ebbs and flows of seasonal migrants.

Check out the scorecard of warblers (and a few other personal first-of-years) that I had each day this week, and note the subtle change in diversity and species dominance as the season advances. Numbers of individuals have not been huge, but numbers of species have been great for the second week of May.

Folks in Portland have been rewarded with daily visits to Evergreen Cemetery and/or Capisic Pond Park, while those closer to Biddeford have headed to Timber Point, for example. But regardless of where you are, there’s a local “patch” to be “worked,” or perhaps to be discovered. And there’s no better time than now!
