The Bradbury Mountain Spring Hawkwatch has been running below average for the season, but the Northern Harrier count has been above average. Recently, views of harriers have also been above average as well.

While it wasn’t “warm” the weather pattern was a little more conducive to migration for the first half of the week. But things are definitely behind schedule right now, and the woods remain uncomfortably quiet. That will change with a weather pattern shift, but for now, my observations of note over the past seven days included the following:

  • 1 Rusty Blackbird Florida Lake Park, Freeport, 4/25 (with Saturday Morning Birdwalk group).
  • BOHEMIAN WAXWINGS are getting quite late now, but there are some still around the area. This week, I had 1 at the Bradbury Mountain Spring Hawkwatch on 4/26 (with Birds on Tap Roadtrip: Hawks and Hops! tour group) and 20-25 from Rte. 136 in Auburn on the 27th.
  • 1 American Oystercatcher, East Point, Biddeford Pool, Biddeford, 4/30.
  • With warbler migration in particular continuing to be quite delayed, it wasn’t until 5/1 at Morgan Meadow WMA that I saw 5 species at one location, led by 60+ Yellow-rumped Warblers and 9 Pine Warblers.

My few personal “first of years” (aka “FOYs”) this week included:

  • 1 Cliff Swallow, Florida Lake Park, Freeport, 4/25 (with Saturday Morning Birdwalk group).
  • 3 Blue-headed Vireos, Mt Apatite Park, Auburn, 4/27.
  • 1 Black-and-white Warbler, Bradbury Mountain Spring Hawkwatch, 4/28.
  • 1 PURPLE MARTIN, Bradbury Mountain Spring Hawkwatch, 4/28.
  • 3 Laughing Gulls, East Point, Biddeford Pool, 4/30.
  • 1 LOUISIANA WATERTHRUSH, Morgan Meadow WMA, 5/1.
  • 1 YELLOW-THROATED VIREO (early, which is surprising since almost nothing else is!), Morgan Meadow WMA, 5/1.
  • 9 Lesser Yellowlegs, Walsh Preserve, Freeport, 5/1.

Birds On Tap℠ – Roadtrip! Warblers and Wort

May 10, 2026; 8:00am – 2:00pm

​Portland Explorer (formerly Maine Brew Bus) and Freeport Wild Bird Supply are excited to continue our collaboration for 3 very special outings in 2026. 

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!

We’re bringing back the “Mother’s Day Special” in 2026, with a return to Portland on one of our most popular annual itineraries. May means warbler migration, and the destination for Warblers and Wort will hit two of Maine’s most famous springtime migrant traps, Portland’s Evergreen Cemetery and nearby Capisic Pond Park. Two oases in the urban jungle, featuring water sources and a mix of various habitats, help concentrate migrant birds that found themselves in or over the city come sunrise. After migrating all night, tired travelers look for refuge: food, water, and shelter, and urban greenspaces are absolutely critical for refueling.  

Warbler diversity will rapidly be increasing, over 15 species possible by the middle of May, depending on the progression of the season. Other species, such as sparrows, raptors, and other Neotropical Migrants such as orioles and tanagers are also on the move, increasing our chances of seeing a diversity of species. If the cemetery’s apples and cherries are blooming, we may be in for quite a treat as these are absolute magnets for hungry migrants.  Meanwhile, most trees have yet to fully leaf out, making them easier to spot! 

​It’s sometimes hard to leave Evergreen on a busy spring morning, but if we do, it will be for the very short trip over to Capisic Pond Park, where we’ll continue to seek migrants of all shapes and sizes.

​After about 3 hours of birding, we will be transported to two of our great local producers to sample their offerings and learn their styles. Our brewery destinations are subject to change, but the current plan is to visit Foundation and Rising Tide Brewing Company.

This Week’s Highlights, 5/17-5/22/2025.

This immature male Orchard Oriole was singing up a storm – when we wasn’t being chased by a territorial male Baltimore – at tiny, but often-productive – Lake Grove Park in Auburn on the 18th.

A sneaky good flight overnight Saturday into Sunday made for a tremendous day of birding: it took me over three hours to leave my yard! The rest of the week, however, was very slow by mid-May standards, with the exception of a very surprising morning At Fort Foster on Friday. My observations of note over the past six days before I head off to Monhegan with my tour group included the following:

  • 17 species of warblers, led by 38+ American Redstarts and 16 Black-throated Green Warblers, our property in Durham, 5/18.

This Ovenbird on our property paused for a moment as it enjoyed a snack it pulled from the leaf litter.

The migratory floodgates really opened this week, as expected, with the diversity of Neotropical migrants increasing dramatically. Days like the 7th and 8th are truly special, but any day birding – especially in May! – yields its own rewards. My observations of note over the past seven days also included:

  • 10 species of warblers (FOY) led by ~40 Yellow-rumped Warblers and 25+ Black-and-white Warblers, Morgan Meadow WMA, 5/6 (with Jeannette).
  • 15 species of warblers (FOY) led by 100+ Yellow-rumped Warblers and 13 Black-and-white Warblers, Florida Lake Park, Freeport, 5/7.

  • 15 species of warblers led by 50+ Yellow-rumped Warblers and 15-20 Black-throated Green Warblers, our property in Durham, 5/8.
  • 15 species of warblers led by 35+ Yellow-rumped Warblers and 20+ Black-and-white Warblers, our property in Durham, 5/10.

As is typical of early May, new arrivals were the headliners of most days of birding. Additional personal first-of-years this week also included:

  • 1 Yellow Warbler, Hidden Pond Preserve, Freeport (with Saturday Morning Birdwalk group).
  • ~40 Chimney Swifts, over downtown Portland at dusk, 5/4 (with Jeannette).

TOURS AND EVENTS:

Nothing like the splash of color from a male Rose-breasted Grosbeak at the feeding station to brighten a gray day in the backyard.

I haven’t been carrying my camera much, and with only one working arm still, my photography has not been very successful. But this Gray Catbird posed nicely for me at Hinckley Park on the 19th.

I had a very busy week of programming, with two tours and some private guiding. With limited free time in between, I made the most of it with some excellent morning outings. Highlights included lots of migrants and more new arrivals, as well as uncommon local breeding birds.

My observations of note over the past seven days included:

  • 16 species of warblers led by 15+ American Redstarts and 10+ Black-and-white Warblers, Evergreen Cemetery, 5/14 (with Down East Adventures Spring Songbird Workshop tour group).
  • Unknown number in a small group of calling Red Crossbills, Evergreen Cemetery, 5/14 (with Down East Adventures Spring Songbird Workshop tour group).

  • 19 species of warblers, led by 14 American Redstarts and 9 Black-and-white Warblers, but also including 5+ Tennessee Warblers, etc, Hinckley Park, South Portland, 5/19. My best warbler morning of the season so far.
  • 4 Red Crossbills, Hinckley Park, 5/19.

My personal FOY’s this week once again included a mix of “they’ve been around for a while but I haven’t been in the habitat,” regular and on-time arrivals, a few species that have been slow to arrive given our abnormal spring weather pattern, and even an oddly early arrival or two.

  • 4 Magnolia Warblers, Florida Lake Park, 5/13 (with Saturday Morning Birdwalk group).
  • 1 YELLOW-BELLIED FLYCATCHER, Florida Lake Park, 5/13 (with Saturday Morning Birdwalk group. Exceptionally early; likely my earliest record by at least several days if not over a week).

With my guiding season now in full swing, I have no choice but to be out in the field a lot, regardless of my shoulder situation. And with much finer weather and some good nights of especially Saturday and Thursday nights, the arrivals of migrants caught up to the date quite rapidly. Many new arrivals – as well as a lot of personal first-of-years since I had not been getting out much – resulted in a nice long list of highlights for me -and my clients – over the past 7 days.

  • 1 female Red Crossbill, Evergreen Cemetery, 5/8 (with client from Spain).
