This Week’s Highlights 10/1 – 10/7/2025.

We were surprised to find a tarrying American Oystercatcher still hanging out on Upper Green Island (where we documented them breeding once again this summer) during our Birds of Casco Bay Boat Tour on the 6th.
  • My tour report from Monhegan, 9/26-9/30, including lots of rarity photos can now be viewed here. Sorry for the delay here, especially for those waiting for the trip list.

Then, my observations of note over the last seven days included the following:

  • Highlights from our Durham property this period included a Tennessee Warbler on 10/2, 1 Rusty Blackbird on 10/3, and 4 American Woodcocks on 10/7.
  • Sandy Point Morning Flight, 10/1.

North to north-east winds are usually not very productive for the Morning Flight at Sandy Point, but the radar images showed a huge flight overnight, so I decided to give it a try. Good thing I did! A northwesterly component inland must have “stacked” birds up against the coast, where they were then influenced by the increasing northeasterly component offshore, producing a better than expected push across the channel. The more I observe the flight here, the more I have to learn! In the end, an unexpectedly good flight passed over and through Sandy Point Beach, Cousin’s Island, Yarmouth, this morning.

Upcoming Tours with Limited Space Available:

October 19, 2025; 9:00am – 2:00pm

​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!). But this time we’re leaving the van in the garage, and hitting the water! That’s right, we’re taking a cruise, and we’re returning to the private House Island in Porland Harbor twice in 2025. 

During last year’s wildly successful outing in which we became the first birding group ever on the island, we found oodles of Yellow-rumped Wabrlers, an uncommon Field Sparrow, and other migrants. But we were truly captivated by Captain Pete, who guided us through the historic fort, sharing a wealth of historical knowledge and fascinating stories. The beer was pretty darn good too, as we sampled the history of Maine’s craft beer scene. 

Building on that success, we’re visiting the private House Island in Portland Harbor twice in 2025. We’ve been granted special permission to come ashore and scour the island here in the peak of fall migration. We’ll follow well-maintained trails through the island’s mosaic of open habitats, scrub, and young woods. These are great habitats to search for a variety of migrants, and perhaps even a rarity!  

Returning in late October, once again rarities will be on our mind. While rare birds are rare, we are still going to expect the unexpected. But more likely are regular migrants of the season such as Yellow-rumped Warblers, a variety of sparrows, and a growing diversity of waterbirds. At the very least, we’ll have resident waterbirds and several species of gulls to sort through. We are having daydreams of a rare flycatcher!

As we motor back across the harbor, we’ll continue to familiarize ourselves with some of the common waterbirds, such as Common Eiders, Common Loons, and the vanguard of our winter diving ducks while enjoying a local craft beverage produced in the city of Portland. While the exact plan is subject to change, we’ll be sure to come up with a plan to adequately celebrate our discoveries – or the one that got away! 

This Week’s Highlights and Shorebird High Counts, 8/9 – 8/18/2025

Suspected of breeding in 2022 and confirmed in 2023, a pair of American Oystercatchers has now nested annual on the tiny Upper Green Islands way up in Casco Bay off Yarmouth. On the 17th, our annual shorebird-focuses Birds of Casco Bay with Seacoast Tours collaboration documented a pair of adults with a juvenile once again. Since we discovered them on this tour in 2022, it’s been exciting to visit them each summer. Who would have thought this tiny island and ledge could support one of only a dozen or so pairs in the entire state?
Full trip report here.

Two birdwalks, two shorebird-centric tours, and two whale-watches made for a very nice, diverse array of observations of note for me over the last 10 days (see note in shorebird high counts):

  • 3 Long-tailed Ducks (2 continuing from previous week), Simpson’s Point, Brunswick, 8/9 (with Saturday Morning Birdwalk group).
  • 1 Bonaparte’s Gull and 6 Great Egrets, Sabattus Pond, 8/11 (with Jeannette).
We checked the underwing patterns of every Cory’s Shearwater we could.
  • 8/12 afternoon Puffin/Whale Combo cruise with Cap’n Fish’s Cruises out of Boothbay Harbor: 5 American Oystercatchers at Eastern Egg Rock. Offshore of EER = 104 Wilson’s Storm-Petrels,  6 Cory’s Shearwaters, 3 Great Shearwaters, 2 Northern Gannets, 1 MANX SHEARWATER.
  • 1-2+ Red Crossbills, Popham Beach State Park, Phippsburg, 8/14.
  • 1 molting adult Bay-breasted Warbler (more evidence of a limited molt-migration in Boreal birds to the southern coastal plain), Old Town House Park, North Yarmouth, 8/16 (with Saturday Morning Birdwalk group).

For my “shorebird high counts,” I prefer to visit at least one of each: high tide hotspot, low tide spot, “grasspiper spot,” and a freshwater location, and it must include a visit to local hotspots Wharton Point and the Walsh Preserve as I attempt to make these comparisons comparable week-to-week and year-to-year, which, for my own notes if nothing else, is why I put these together (but hope you find them of value, too). Just due to life and scheduling, it now often takes me more than a week to hit all of these “requirements,” so I am going to try and do every 10 days instead of weekly. Therefore, here are my high counts over these past 10 days:

  • American Oystercatcher: 5, Eastern Egg Rock, 8/12 (via Cap’n Fish’s Cruises Puffin/Whale combo trip). Plus 3 (2 ad with 1 juv), Upper Green Island, 8/17 (with Birds of Casco Bay with Seacoast Tours tour group). Photo above
  • Black-bellied Plover: 163, The Pool, Biddeford Pool, 8/18 (with Down East Adventures Shorebird Workshop group).
  • Killdeer: 13, Crystal Spring Farm, Brunswick, 8/9 (with Saturday Morning Birdwalk group).
  • Semipalmated Plover: 300+, The Pool, 8/18 (with Down East Adventures Shorebird Workshop group).
  • Piping Plover: 13, Popham Beach State Park, 8/14.
  • Ruddy Turnstone: 3, multiple locations this week.
  • Sanderling: 20, Popham Beach State Park, 8/14.
  • 1, Popham Beach State Park, 8/14 and 1 at Great Pond, Biddeford Pool, 8/18 (with Down East Adventures Shorebird Workshop group).
  • Least Sandpiper: 42, Sabattus Pond, 8/11 (with Jeannette).
  • White-rumped Sandpiper: 15, Hill’s Beach, Biddeford, 8/18 (with Down East Adventures Shorebird Workshop group).
  • Semipalmated Sandpiper: 1600, The Pool, 8/18 (with Down East Adventures Shorebird Workshop group).
  • Short-billed Dowitcher: 40, The Pool, 8/18 (with Down East Adventures Shorebird Workshop group).
  • Spotted Sandpiper: 4, Sabattus Pond, 8/11 (with Jeannette).
  • Lesser Yellowlegs: 66, Royal River, Yarmouth, 8/17 (with Birds of Casco Bay with Seacoast Tours tour group).
  • “Eastern” Willet: 24, Pine Point, Scarborough, 8/18 (with Down East Adventures Shorebird Workshop group).
  • “WESTERN” WILLET: 1 (FOY), Pine Point, 8/18 (with Down East Adventures Shorebird Workshop group).
  • Greater Yellowlegs: 22, Wharton Point, Brunswick, 8/9 (with Saturday Morning Birdwalk group).
Just including this Wilson’s Storm-Petrel photo here because it is incredible. Nice job, Bill!

Recent Highlights, 8/26 – 9/2/24

Jeannette and I spotted these four Red-necked Phalaropes from the Casco Bay Ferry Mailboat run with visiting family on the 26th.

It was a very busy week for me, but when I did get out, birding was productive – especially in the backyard which hosted at least 15 species of warblers this week. Meanwhile, shorebirding continues to be hot. My observations of note over the past 8 days included the following

  • 1 Black Scoter, 2 White-winged Scoters, and 2 Blue-winged Teal with Common Eiders, Reid State Park, Georgetown, 8/27. As scoters begin to increase in September, I’ll forgo reporting the “oversummering” groups from now on.
  • 1 TRICOLORED HERON, Mill River Park, Thomaston, 8/29 (with Jeannette).
  • 2 SANDHILL CRANES, Mayall Road, Gray/New Gloucester, 8/30.
  • 1 Northern Pintail (first of fall) and 1 juv, Little Blue Heron, etc, Eastern Road Trail, Scarborough Marsh, 8/30.
  • 3 adult Lesser Black-backed Gulls, Seawall Beach, Phippsburg, 9/2 (with Ed Hess).

My shorebird high counts for 18 species this week were solid considering I didn’t make it to Biddeford Pool (or Pine Point) during this period. Focusing on mostly lesser-visited hotspots, I found several goodies and had a few decent high counts.

  • Black-bellied Plover: 67, Wharton Point, Brunswick, 9/2 (with Ed Hess).
  • Killdeer: 43, Colonial Acres Sod Farm, Gorham, 8/30.
  • Semipalmated Plover: 100+, Thomaston Public Landing, 8/29 (with Jeannette).
  • HUDSONIAN GODWIT: 2 adults, Wharton Point, 9/2 (with Ed Hess)
  • Ruddy Turnstone: 1, Reid State Park, Georgetown, 8/27.
  • RED KNOT: 1 juv, Wharton Point, 9/2 (with Ed Hess).
  • Sanderling: 82, Seawall Beach, Phippsburg, 9/2 (with Ed Hess).
  • BAIRD’S SANDPIPER: 1 juv, Seawall Beach, 9/2 (with Ed Hess).
  • Least Sandpiper: 92, Eastern Road Trail, Scarborough Marsh, 8/30.
  • White-rumped Sandpiper: 3, Eastern Road Trail, Scarborough Marsh, 8/30.
  • Pectoral Sandpiper: 3, Eastern Road Trail, Scarborough Marsh, 8/30.
  • Semipalmated Sandpiper: 1500, Thomaston Public Landing, 8/29 (with Jeannette).
  • Short-billed Dowitcher: 16, Walsh Preserve, Freeport, 8/31 (with Saturday Morning Birdwalk group).
  • Spotted Sandpiper: 5, Reid State Park, Georgetown, 8/27.
  • Solitary Sandpiper: 1, several locations this week.
  • Lesser Yellowlegs: 45, Walsh Preserve, Freeport, 8/31 (with Saturday Morning Birdwalk group).
  • Greater Yellowlegs: 24, Walsh Preserve, 8/31 (with Saturday Morning Birdwalk group).
  • RED-NECKED PHALAROPE: 4, Casco Bay between Little Chebeague and Cow Islands from the Casco Bay Lines Mailboat run, 8/26 (with Jeannette).

This Week’s Highlights, August 6 – August 12, 2022.

Here are three of the incredible 26 White Ibis that were found in Webhannet Marsh in Wells beginning on August 10th when one was photographed. I was able to see them in the late morning on the 11th, as the number grew. Most interestingly, we observed them eating Green Crabs (such as the one on the left)!  Well, we know we have enough of those invasive species around, so maybe we just need more White Ibis!

All. The. Shorebirds. And rare wading birds! Here are my observations of note over the past seven days:

  • 1 TRICOLORED HERON (my first pure TRHE of the year), Eastern Road Trail, Scarborough Marsh, 8/9 (with Jeannette).
  • 26 WHITE IBIS, Webhannet Marsh, Wells, 8/11. 29 were present earlier, but I had to settle for “only” 26. Either way, wow…A flock of White Ibis!  Rapidly expanding up the Eastern Seabird, this was just a matter of time.

Shorebird high counts this week, with many species now peaking:

  • AMERICAN OYSTERCATCHER: 2 ad with 1 juv, Upper Green Island, Casco Bay, 8/12 (with Seacoast Tours and private tour group). Is this a family group from Ram Island, or perhaps another pair is now breeding further up the bay?

  • “Eastern” Willet: 8, Pine Point, 8/7 (with Down East Adventures Shorebird Workshop Group).
  • “WESTERN” WILLET (FOY): 3 juv, Hill’s Beach, 8/7 (with Down East Adventures Shorebird Workshop Group).
  • Greater Yellowlegs: 24, Royal River, Yarmouth, 8/12 (with Seacoast Tours and Private Tour Group).
  • WILSON’S PHALAROPE: 1 molting juv, Eastern Road Trail, 8/8 (with client from NY). Phone-scoped video here: https://fb.watch/ePAQA03F_3/
Well, it wasn’t a rare bird, but I really liked this photo of a Ring-billed Gull from Sebago Lake Park on 8/11. In came to check out if I was going to have a snack after my weekly dip in the lake.
