Additional Highlights This Week, 10/16-22

Here’s the world’s worst photo of the Orange-crowned Warbler that appeared at Sandy Point on Tuesday. I drew an outline around it to (maybe) help you find it. It was my 8th ever here.

My non-Sandy Point observations of note over the past seven days included:

  • ~60 American Pipits, Mayall Road, Gray/New Gloucester, 10/16 (with Saturday Morning Birdwalk group).
  • Sabattus Pond, Sabattus, 10/19 (with Jeannette). Choppy water made a thorough count challenging.

360+ Ruddy Ducks

173+ mixed Greater and Lesser Scaup

31 Mallards

15 WHITE-WINGED SCOTERS

3 Buffleheads

2 Common Loons

  • 1 Nashville Warbler, 4 Red-throated Loons (FOF), etc, Peak’s Island, 10/22 (with Dan Nickerson).

Additional (non-Sandy Point) Highlights This Week, 10/2-8, Pelagic reminder, and Monhegan trip report.

This Savannah Sparrow contemplated walking across the channel instead of flying over the water during Morning Flight at Sandy Point.

A few observations of note away from the Morning Flight over the past seven days for me included:

  • 1 CLAY-COLORED SPARROW, Wolfe’s Neck Center, Freeport, 10/2 (with Saturday Morning Birdwalk).
  • Overall, it was a great week of sparrow migration, with a nice high count on 10/8 from Wolfe’s Neck Center of 125 Song, 100 Savannah, 75 Swamp, 25 White-throated, 2 White-crowned, and 1 Lincoln’s.
  • Sabattus Pond season is underway as well!  On 10/8, I had early-season tallies of 76 Ruddy Ducks (first of fall), 33 Lesser Scaup, 18 Greater Scaup (first of fall), 2 Ring-necked Ducks, 2 Red-breasted Mergansers (first of fall), etc.

Notes:

  • And I’ve finally posted my tour report from Monhegan, 9/24-9/28. The blog includes photos and daily checklists:

Exceptional Morning Flight at Sandy Point, 9/29/2021

The carnage of this morning’s Morning Flight.

I don’t usually post my Sandy Point Morning Flight totals here, but today was more than worthy of a little something extra.  After 8 nights with little or virtually migration (well, at least not a big flight on ideal winds), clearing skies and a light northwesterly breeze finally opened the floodgates.  Here are the 1:00am reflectivity and velocity images, for example.

I am sure Monhegan – where I just spent 5 glorious days (despite the lack of a huge flight; more on that soon!) – was great, Sandy Point was just outstanding.  In fact, it was my 3rd highest all-time flight!

Early on, clouds made everything into little black shapes as the intense flight proceeded at all levels. Wind, a cacophony of kinglets ringing in my ears, and the two loudest and most vociferous Tufted Titmice who just stayed screaming in the magic birch all conspired to further reduce my ability to identify birds. But mostly, waves of dozens at a time were simply clicked as “unidentified” as I tried to keep pace with quantifying the flight. Furthermore, there were at least 3-4 hunting Merling, a Cooper’s Hawk, and a Peregrine Falcon, which added to the swirling chaos. It was a challenge, that’s for sure. “I do this for fun?” I asked Matthew.

Here’s the scorecard from the Morning Flight of birds that passed over and through Sandy Point, Cousin’s Island, Yarmouth this am:

1 YELLOW-BILLED CUCKOO – my 7th all-time here. Made 4 “false starts” before crossing at 10:04am.

Cuckoos are such shape-shifters in flight that I feel like I could have counted each pass from the one bird as a different species each time it passed!

For a grand total of 5,487 birds, my *3rd highest all-time count.  So yes indeed, birds have very much been backed up.

Meanwhile, adding to the excitement (and chaos) this morning was a massive feeding frenzy of Double-crested Cormorants and gulls. While I am sure a few migrants snuck by overhead, I couldn’t help but take a few moments to enjoy it…and make sure there were no rarities among the gulls!   15-20 Laughing Gulls and 4 Bonaparte’s Gulls joined 75-100 Ring-billed Gulls in snatching the baitfish that the Double-crested Cormorants had pushed right up onto the sandbar as it slowly emerged from the tide.  It was quite a show!

Derek’s Birding This Week: 9/18-23, 2021

The weekend will likely start off wet, but with several days of an extensive southerly flow originating all of the way from the Gulf Coast and Deep South, vagrants – like Blue Grosbeak, Hooded Warbler, Summer Tanager, and much more will be on our minds.

As I prepare to depart for our Monhegan Fall Migration Weekend tour tomorrow, I am left to wonder where the heck the past week went!?

Similarly to last week, my birding time was woefully limited thanks to excuses including a trade show and a morning meeting. Therefore, my birding this week was mostly limited to our Saturday Morning Birdwalk and one great flight at Sandy Point.

Speaking of Sandy Point, I did not make it out for what was presumably a light flight on Monday morning, and of course a Clay-colored Sparrow – a long-overdue Patch Bird – was found. It wasn’t until Wednesday morning that I had a chance to look for it.  While I didn’t find it, I did get a consolation prize.  With a flock of about 400 Semipalmated Sandpipers in the cove on the north side of the point – the largest peep flock that I have seen here, I grabbed the scope. Among them was a single Sanderling, but also a single molting juvenile Dunlin – my 191st all-time species at Sandy Point!

There was a big movement of White-throated Sparrows this week however, augmenting productive feeder-watching. Granted, my extended period of afternoon feeder-watching on Monday was mostly limited to the entertainment of a constant dog-fight between a Sharp-shinned and Cooper’s Hawk for backyard supremacy

Now, let’s hope the forecast for the weekend is a little drier than currently called for!  That being said, the pattern that we are in looks really good for southern vagrants (see photo above), and especially after 5 days of poor winds for migration, once this mess clears, the migration could be huge!

Derek’s Birding This Week: 9/11-17, 2021

Philadelphia Vireos have been particularly conspicuous this week at Sandy Point, especially because of their propensity for stopping by the trees right next to “my office” as they contemplate crossing.

I didn’t get out birding much this week, other than at Sandy Point (see tallies here), and when I did, it was mostly just enjoying the local, regular passerine migrants.

In fact, my only observation of note was a good evening at the Walsh Preserve in Freeport on 9/14 with Jeannette, where a great late-season array of shorebirds included:
1 juv. LONG-BILLED DOWITCHER, 1 juv Dunlin (FOF), 76 Lesser Yellowlegs, etc,

Meanwhile, limiting most of my outings to local dog-walking patches and our two yards (home and the store), afforded the opportunity to enjoy lots of up-close migrants this week, including a Nashville Warbler that has been frequenting our dripper at home. Unfortunately, the LARK SPARROW that Will and Jeanne had here at the store on Monday, 9/13, has not returned.

Comparing my notes to last year, the first stages of the “super flight” of irruptives over the winter was already prevalent in these parts with many more Red-breasted Nuthatches and Purple Finches than normal, and the first Pine Siskins of the season. This year, Purple Finches have been in short supply so far, Pine Siskins have been virtually non-existent, and migrant Red-breasted Nuthatches have been limited (although it seems we had a good breeding season locally).  Also at this  time last year, a massive early flight of Dark-eyed Juncos and well-above normal numbers of White-throated Sparrows were around, likely signaling a low year of seed productivity.  This year, those species are around in more seasonable numbers so far this season

A Record-Shattering 5 Days at Sandy Point!

NOPA
Northern Parulas were certainly the “bird of the week” at Sandy Point.

It was a special five-day run at Sandy Point Beach on Cousin’s Island in Yarmouth. It was a record-shattering run in fact, in which I tallied nearly 18,000 migrants engaging in the “Morning Flight,” or “morning re-determined migration” when nocturnally-migrating passerines relocate (to drastically oversimplify things) come sunrise.
SandyPoint_sunrise,9-13-17

(To learn more about Sandy Point, check out the site entry in Birdwatching in Maine: A Site Guide, and for more on nocturnal migration, interpreting the radar, and the “morning flight” phenomena, check out Chapter 5 in my first book, How to Be a Better Birder. Whaddya mean you don’t have these two books!?)

I’ve had a handful of four-day runs, but I cannot think of a time when conditions were favorable – and I was actually present, and not leading tours on Monhegan for example – for five straight days. But I have most certainly never had five days like this!

I recorded 72 species “deemed migrating” through here, not including migrants that were in the bushes, such as the Gray Catbirds and Song Sparrows that are so abundant in the brush here. It does not include species like Osprey, in which some of the many I saw this week were likely southbound, but impossible to separate from the still-locals. And this tally did not include all of the waterbirds, from Common Eiders to herds of dabbling American Black Ducks, and from Bald Eagles to hunting Great Blue Herons, as well as resident species.

I tallied 25 species of warblers, including a single Connecticut Warbler, one of the most sought-after parulids in Maine. A Northern Mockingbird was only my 5th ever noted here, and two passing Dickcissels are always a treat. But certainly the icing on the cake of this great week was the Lark Sparrow found by the group in the parking lot on the relatively quiet morning of 9/13. This was a first record for Sandy Point, and my personal 184th species here.
LASP, Becky

But it was the morning of the 11th that will go down in Sandy Point history!  8,185 migrants was not only a new record, but almost doubled the previous record (4,346 on Sept 21, 2010). It was incredible. More on that epic morning later.

A number of records for high counts for individual species were set, and I am sure even more would have been shattered if I had a higher rate of identification during the onslaught of the 11th.   Other trends, typical of the season, were evident, such as the slow but steady change in the composition of the flight. The early migrants like Magnolia Warblers were giving way to a growing percentage of Yellow-rumped Warbles and Blackpoll Warblers for example. But it sure seems like we’re not yet running our of Yellow Warblers and American Restarts, however!

Now, let’s take a look at the radar. Here are the density and velocity images from 1am (as a sample) on 9/9 and 9/10. That’s a ton of birds on the radar.
1amRadar,9-09-17
1amVelocity,9-09-17

1amRadar,9-10-17
1amVelocity,9-10-17

And even as late as 4:00am on each day, a lot of birds were visible, and a lot of birds were offshore.
4amRadar,9-09-17
4amRadar,9-10-17

The night of 9/8 through 9/9 featured light westerly winds, shifting to northwest by sunrise. And on the next night, light north winds became northwest overnight. Both, as expected, produced great flights over and through Sandy Point some dawn.

Weather patterns, especially at this time of year, rarely produce three great nights for migrants in a row. And when they do, it often results in fewer birds overnight (and therefore at Sandy Point) come sunrise; essentially, the well temporarily runs dry.

And as you can see by the 1:00am radar image from September 11th, the density was nowhere near the previous two nights, despite mostly light westerly winds overnight.
1amRadar,9-11-17
1amVelocity,9-11-17

And by 4:00am, it was rather quiet.
4amRadar,9-11-17

Light northwesterly winds in the evening slowly gave way to light north, before becoming light and variable. After midnight, they became west but didn’t really increase until after 2:00am. Coupled with a lackluster radar return, this was not a recipe for a huge flight.

Nonetheless with a light westerly wind at sunrise, I was heading to Sandy Point anyway. If only because it was a day off, and I won’t have many more chances to visit “my office” this month. A milky sunrise further clouded (sorry) my optimism for a big flight, but there were plenty of birds in the air.
Sunrise_on_big_day_atSP,9-11-17

And then all hell broke loose.

It was incredible. It was frustrating. It was beautiful. It was painful. It was amazing. It was indeed overwhelming, and at times, my only hopes at quantifying the flood was to skip attempting identification and just click my unidentified clicker as fast as I could.

And I really can’t explain it. It “shouldn’t” have been this amazing.

Come nightfall, with high pressure remaining in control, and with light westerly winds and clear skies once again, a moderate to strong flight occurred overnight. Here are the 1:00am and 4:00am radar images from the wee hours of 9/12:
1amRadar,9-12-17
1amVelocity,9-12-17

4amRadar,9-12-17

With light westerly winds come dawn, I was once again stationed at the bridge, and what was – prior to three days ago! – considered a very good flight passed over and through. It was even downright relaxing – and manageable – after the chaos of the previous morning. I had fun.

Not surprisingly, after four consecutive nights, the flight was much lighter overnight on the 12th into the 13th, as evidenced once again by the 1:00am and 4:00am images.
1amRadar,9-13-17
1amVelocity,9-13-17

4amRadar,9-13-17

And despite very light westerly winds in the morning, and clear skies, only a light flight was to pass through the point. Of course, that Lark Sparrow more than made up for it. It was also nice to enjoy a slower flight – and identify many more birds than not!

So almost every morning made sense: radar plus weather conditions correctly predicted the intensity of the flight. Except for one. The Big One. And I can’t explain it. But, I am OK (mostly) with that – it’s one of the fascinating and flabbergasting aspects of documenting the morning redetermined migration!

Winds turned to the south during the day on the 13th, and continued light and southerly overnight, bringing the streak of five great nights of migration to an end. Come morning, I also slept in – relatively speaking – and then went for a massage. As my therapist began to work on my aching neck, she simply uttered, “Wow” and got to work. I felt the same on Monday morning when the greatest flight I have ever recorded passed through Sandy Point.

IMG_6455-edited-edited
Species, such as this Swainson’s Thrush, that can be rather secretive in migration, are sometimes seen really well at Sandy Point!

Rarity Season is Upon Us!

I do like a good storm system. Especially as Rarity Season is now upon us! So besides our desperately-needed rain, I was anxious for this weekend’s weathah in the hopes it will set up some action for my favorite time in the birding year.

The winds turned east on Thursday (10/20), and strengthening easterly winds, scattered showers, and developing fog minimized the migration overnight into Friday morning. It was hard to tell from the radar is there was some limited, low movement, which would be indicative of the sparrows that move this time of year. Florida Lake Park was slow in the morning, though, and nothing new was under our feeders at home or at the store, however.

During the day on Friday, a shortwave moved out of the Ohio Valley, and overrunning precipitation fell during the day. By dark, however, that low was deepening and strengthening, and overnight, it tapped tropical moisture, leading to torrential rains, isolated thunderstorm, and by far our best soaker in at least 6 months: 3-6 inches of rain fell over the area! Southeasterly winds turned back to the east before going calm with thickening fog by morning.
wind-map-10-21-16

Fog and a little drizzle on Saturday morning was all that our Saturday Morning Birdwalk had to contend with on our outing to Wolfe’s Neck Farm; it does seem like there are more Laughing Gulls around later this year than I can ever remember (just the warm weather or are these related to Hurricane Mathew?).

The low slowly moved into the Canada, with an onshore flow (I had hoped for more southwesterlies) throughout the day. On the backside of the system, winds shifted to the west overnight while more rain and showers continued from the afternoon through the first half of the night. Winds were howling west by the morning, and the air definitely felt seasonable for a change.
wind-map-10-22-16

With the storm system pulling away to the north…
wind-map-10-23-16

…and the temperatures falling (and even some snowfall was seen in the mountains!) it’s time to really go birding!
surface-map-10-23-16

On Sunday, Phil McCormack and I headed over Peak’s Island, a place I really want to spend more time searching in the fall. Afterall, it’s a mere 15-minute ferry ride, there are a variety of interesting habitats, and the maritime climate tempers the onset of the seasons a little more. In other words, it looks good for rarities! (And you know I need to seek them somewhere other than Portland now!)

And with my Rarity Fever stoked, a productive morning of scouring the southern 1/3rd of the island yielded the seasonal rare-but-regular stuff that makes one keep coming back: A Clay-colored Sparrow, a Yellow-breasted Chat, and an Orange-crowned Warbler (my second of the season). Add to that single Nashville and Palm Warblers among a total of 6 species of warblers, a fly-by flock of 57 Brant, 8 lingering Red-winged Blackbirds, a good Northern Gannet flight, a Merlin, and recently arrived Red-necked Grebe and 9 Red-breasted Mergansers and you can see why I will be birding here more and more (my once a fall needs to become at least 3-4 visits each season, me thinks).

peaks_shoreline10-23-16_edited-1

There wasn’t any migration visible on the radar overnight, but there were southwesterly winds – the direction that can help facilitate the arrival of vagrants to the Northeast. But with winds once again rapidly increasing during the day on Monday, the detection of birds was limited. However, Jeannette and I enjoyed a visit to a particularly productive patch of private property in Cape Elizabeth, where a Blue Grosbeak and a Clay-colored Sparrow that I found last week continued. Dark-eyed Juncos increased to 100+ and White-throated Sparrows were up to 50. Other sparrows had decreased, as expected, but there were still 75 or so Song Sparrows, 6 Chipping, and 2 White-crowned, along with about ten each of Swamp and Savannah. Singleton Indigo Bunting and Common Yellowthroats were both getting late.

With the low pressure system still spinning over the Maritimes, and another shortwave disturbance rotating through, winds remained gusty through the night. Despite the preferred northwest wind (slowly becoming west through the night) there were just not a lot of migrants willing to deal with the winds and likely resultant turbulence overnight. And the winds were gusty and increasing by dawn once again.

I was in Harpswell for the morning, leading a birdwalk for the Curtis Library as part of their fall reading series. Mitchell Field, a true hotspot at this time of year, was our destination, but it was anything but hot from a temperature perspective! However, there were a bunch of Yellow-rumped Warblers and a few flocks of migrant Common Grackles easily eclipsed 1,000 – a sign that it wasn’t just the birders who were thinking that it’s finally starting to feel like winter is approachintg! Migrant Turkey Vultures (10), Sharp-shinned Hawks (4), and a trickle of Northern Flickers were also winging it south.

Despite the wind, I poked around a couple of other spots on the peninsula since I was down there, with Stover’s Point yielding a 3 Horned Larks, a “Yellow” Palm Warbler, and 9 Black-bellied Plovers among others. But it was windy!
stoverscove10-25-16

Winds died down a little overnight, finally, and with it, some birds took to the air. For the first time in seven days, there was at least a moderate flight underway. Here’s the 10pm radar image for example, which shows a strong flight underway:
10pm-radar10-25-16

But by 1:00am, the flight was already rather light, suggestive of the short-distance migrants of the season making a little bit of progress, but for the most part, more birds departing than arriving:
1am-radar10-25-16

And therefore, Sandy Point wasn’t as great as I had hoped for on Wednesday morning. However, I still enjoyed a respectable morning flight for this time of year. A total of 444 individuals of 22 species were led by 262 American Robins and 82 Common Grackles, but also included my first Fox Sparrow of fall, my 3rd Orange-crowned Warbler of the season (and only the 6th Sandy Point record), and this very tardy (or perhaps, “reverse” or 180-misoriented) migrant Prairie Warbler.
prawsandypoint10-26-16_edited-1

Strong northwest to northerly winds continued through the day, but they are finally expected to lighten up overnight. The current forecast looks good for a big flight tonight, and, if the winds stay more northwest – or at least north – than northeast by morning, I might get a “big one” at Sandy Point.
10-27_wind_forecast
wind-map-10-26-16

I sure hope so, as I haven’t had a lot of great mornings there this year, between all of my time on Monhegan, our recent quick trip to Cape May, and the overall lack of cold fronts this entire fall. The good news is that it seems to be changing now, and at the very least, a more active weather pattern should not only bring some more rainfall, but some good winds for producing good birding. While weather doesn’t necessarily cause vagrancy of fall migrants, winds certainly facilitate their arrival in far-off places.

Hopefully, the onset of cooler weather and more north and northwesterly winds will usher them to the coast and concentrate them in those seasonal hotspots that I will be hitting hard in the coming weeks. Also, this series of strong low pressure systems could in fact displace some birds, or at least get birds that are still on the move a littler further northeast (I am of course, drastically over-simplifying the mechanisms of vagrancy here). At the very least, the little bit of snow to our north and west, colder nights, and the end of our growing season – and resultant greatly diminished numbers of insects and other food sources – should help those patches that get better when the weather turns towards winter.

You know I’ll be out looking! So stay tuned to our store’s Facebook feed and other resources, all of which are available at our website, for the latest news. And go birding! Rarity Season is upon us!

Excellent Morning Flight at Sandy Point, 9/16/2015

Over 2,000 migrants. 45 species, including 17 species of warblers. Yeah, it was a good morning to be at Sandy Point!

L1030171_CMWA,SandyPt,9-1-15_edited-1
Cape May Warbler, male.

I arrived, as usual, a few minutes before sunrise, but unlike most mornings, birds had already begun to cross. And once the sun crested the horizon, the floodgates open. OK, so it wasn’t “Warblergeddon” at Cape May, but it was fun for me and it was an excellent flight for here.

Well, mostly fun. A lot of birds were high, especially as the wind went calm. Big pockets of birds were just too high to identify. I did my best to just keep count. Birds were dropping into the trees on both sides of the road, others were zipping through underneath. As I focused on something in the elm, I am sure I missed birds overhead. It was tough to keep track, but I did my best.

Black-throated Blue Warbler, male. Look at how the “pocket hankercheif” is blown out by the low sun angle.

Several counts were noteworthy, including the two record highs. Tree Swallows usually don’t bother crossing from the island to the mainland via Sandy Point, but more often continue on to the south, crossing the bay with little trouble. Plus, most swallows are probably moving through after I depart in the morning. These birds, mostly in one large and a couple of small groups, were funneling over the bridge along with the rest of the typical Morning Flight migrants. Meanwhile, the 5 White-breasted Nuthatches were noteworthy as I usually see no more than a couple all fall here. The previous record for a single morning was two.

As for the higher counts, I was surprised by how large of a percentage of identified migrants were American Redstarts compared to Blackpoll Warblers. However, I think this is an “identification bias.” Redstarts are the easiest warbler to ID for me in flight, and few pass through at almost any height without being identified. I doubt many of the overwhelming “unidentified” count were redstarts. However, I would wager that a sizeable percentage of them were Blackpoll Warblers. Based on the date and what I’m seeing in the woods these days, there should have been a lot more blackpolls. However, these strong fliers are often very high overhead on light winds, and my guess is that the diminishing westerly this morning was of little consequence for them, and that a lot of those little dots overhead were blackpolls.

Yesterday, I was lamenting not being at Sandy Point. The conditions were great in the morning, and the radar was quite good overnight. However, I was guiding in the Camden area, and at least a little morning flight (ca 100 birds) flew over and through Merryspring Nature Center Park in town. It was a tease to think what might have been going on at “my office” however.

But last night’s radar was even better! Here are the very active 10pm, 12am, 2am, and 4am radar and velocity images from the overnight. See how much was offshore, even as of 4am?

And come dawn, the winds aloft were perfect for a good Morning Flight at Sandy Point.

In other words, that’s what produced 2,000 birds at Sandy Point, and with a busy schedule this fall, I was quite pleased to catch one of the big ones.

Morning Flight Fail

Following yesterday’s cold front, a huge flight was underway come nightfall. It was by far the biggest of the season to date, and one of the stronger (by density) flights as you can see around here.

Here are the midnight radar and velocity images, for example:
12am_radar

Even as of 4:00am, with the eastern sky likely showing a little light, the flight was still strong:

So of course I was up early to go to Sandy Point. However, the winds were forecasted to be out of the northeast, becoming easterly in the morning. And, the local weather stations I looked at (and my windometer at home ) were all reading north or northeast when I awoke a little before 5:00 this am. The 6:00am Intellicast “Wind cast” image shows this coastal northeasterly wind very well:
6amWIND_map

After almost any night in the fall with a little migration, there will be a few birds at Sandy Point. And after a migration as strong as last night’s, there were bound to be some birds. However, due to a combination of geography and the instinct to fly into the wind to compensate for overnight drift (to oversimplify things a bit), there are just never a lot of birds at Sandy Point on northeasterly winds.

On the other hand, on both north and northeast winds, I have witnessed good morning flights (aka Morning Re-determined Migration” or “Morning Reorientation”) in the south-facing peninsulas that reach into Casco Bay, including the dual peninsulas of Harpswell.  What I have not figured out yet, however, is which point is best, how, and when. This is mostly because I can’t tear myself away from Sandy Point long enough to find out!

But this morning, as I reached I-295, something made me turn north instead of south. With what was supposed to be an increasing northeasterly wind and a huge flight, this should have been a perfect morning to test my hypotheses at the tip of Harpswell.  So, with no small feeling of impending regret, I drove down to Pott’s Point at the end of Rte 24 for the dawn.

As birds that were over and beyond Casco Bay at sunrise begin to work their way inland and compensate for that drift, island-hopping to the north and northeast deposits birds in the long fingers of the Mid-Coast. Unlike Sandy Point on Cousin’s Island, however, there isn’t a single leading line, perfectly-pointing peninsula, narrow crossing, and raised bridge (for visibility) that combine to offer a perfect morning flight observation location.

So I thought today would have been a perfect morning to see if Pott’s Point was the answer on a northeasterly wind, even if it meant missing a few birds at Sandy Point.

I was wrong.

I arrived at the end of Pott’s Point at 6:27, 20 minutes after sunrise, but found the wind to not be northeast, or even north, but to be north-northwest. Uh-oh, I thought.

But since I have yet to find a way to be in two places at once, I settled in for the next hour at Pott’s Point (it would have taken at least 45 minutes to get from Pott’s Point to Sandy Point), and counted…very, very little:
16 Cedar Waxwings
11 American Goldfinches
5 American Redstarts
5 Unidentified
2 Yellow-rumped Warblers
1 Pileated Woodpecker

Now, all of those birds were doing the “right” thing, flying from over the bay or from Haskell Island just to the south, then over Pott’s Point and northward up the peninsula.  There were just so few of them!

CousinsIslandPowerPlant
If I only had a boat…

The view of the top of the power plant at the other end of Cousin’s Island was a reminder of what could have been, as Sandy Point is excellent in a NNW wind. Was I missing a huge flight? Or, were the winds northeasterly on the other side of the bay, and only a light flight was passing through there (although it would have undoubtably been better than the “flight” at Pott’s, I will convince myself of the latter!)?

In other words, I was here:
PottsPointMap

But should have been here:

Besides, it’s a peaceful spot to spend the morning, with the only traffic being a few lobster boats.

And the narrow peninsula does have a Monhegan-esque feel to it and its birding (sometimes).

So if the migrants were not at Sandy Point, where was the Morning Flight concentration this morning?  Looking back at the radar images, there was not a ton of offshore drift (due to the lack of a westerly component throughout the night), so maybe there just weren’t a lot of birds offshore come sunrise.  But there still looks like more than enough for a good reorientation flight at sunrise.

Bascially, I am not only left without an answer to my pursuit of a good Mid-Coast morning flight spot, but now I will no doubt spend the rest of the season being over-cautious about missing a flight at Sandy Point and therefore miss the next huge flight through Pott’s Point on a northeasterly wind!

There wasn’t much else left to do but go birding, so I poked my way up the peninsula and into Brunswick, checking a few of the hotspots. Some day I will find a rarity at Stover’s Point, but today wasn’t the day for that either. However, I did have some pretty good birding at Mitchell Field, including a trickle of warblers overhead. A Yellow-bellied Flycatcher and a Lincoln’s Sparrow were highlights, and other migrants present included seven species of warblers. OK, it was small consolation, but at least there were some migrants around Harpswell today!

Unfortunately, the wind and weather forecasts for the coming days hardly look good for Sandy Point, so it might be as much as a week before I am back to spending the sunrise at “my office” where I should be!

P.S. It’s not too late to sign up for my “Morning Flight Phenomenon on Cousin’s Island” workshop for RSU5 Recreation and Community Education next week. More information and registration details are here.

9/5 UPDATE: I received an email this morning from Bill Hancock who was at Sandy Point on Friday and reported it was “dead” and did in fact have a northeasterly wind. Phew!  Meanwhile, I tallied 110 migrants on calm conditions on Saturday morning – a very light flight, as expected this time.

This Week in Shorebirds: 8/22-28/2015

L1030121_BASA1_edited-1
Two juvenile Baird’s Sandpipers at Popham Beach State Park on Friday morning, “rare-but-regular” fall migrants.

August is for shorebirds. Although the “fall” southbound migration started in late June (when the first non-breeders begin to turn around to mosey back south) and continues into November when Purple Sandpipers are still filling in, August is the month of peak numbers and diversity in Maine.
Most weeks from mid-July into September of recent years, I post a weekly “shorebird high counts this week” summary to my weekly “Additional Highlights This Week” summary posts to the Maine-birds listserve. While I do hope this is interesting and of value to folks, I also do it to organize my own notes, allowing me to quickly reference the peaks and valleys of particular species with ease should I need to.

I generally only post this when I have hit at least two “primary” and at least one “secondary” site each week, to make the numbers meaningful. And I prefer at least one prime high tide location (Eastern Road Trail in Scarborough Marsh, Biddeford Pool Beach/Ocean Avenue, or Popham Beach State Park in some years) with one low or mid-tide hotspot (Pine Point, Hill’s Beach/The Pool, or Popham and nearby environs).

This week was a particularly productive week for my own shorebirding, so this week’s summary is a helpful future reference for me. I also thought it was worth going into a little more detail, since it yielded a goodly 21 species (plus one subspecies) and some excellent totals.

The inclement weather of the weekend into the middle of the week (regular rain, lots of fog, easterly or southerly winds) was perfecting for “grounding” shorebirds and allowing numbers to build. I think my only surprise was my lack of a real rarity – like Western Sandpiper (although I worked pretty hard for one!)

I hit the low-tide hotspot of Pine Point on Monday with Jeannette, followed by the Eastern Road Trail at high tide later that afternoon. Jeannette and I spent the incoming to high tide at Biddeford Pool Beach on Tuesday, and on Friday, Serena Doose and I visited Popham on the incoming to high tide. Additionally, Jeannette and I checked one of the “secondary” sites, Brunswick’s Wharton Point on Tuesday and on Thursday I visited Wells Harbor before the evening’s Scott Weidensaul talk that we co-sponsored with Birds and Beans coffee and York County Audubon.

It’s always good to hit a freshwater location for diversity and high counts of pond-preferring-migrants, so when my Poplar Hut Tour Group with Maine Huts & Trails visited the Carrabassett Valley Snowfluent Ponds on Sunday, my high counts of Spotted and Solitary Sandpipers were acquired, along with my only Wilson’s Snipe of the week.

And, as if often the case during the peak of shorebird migration, there is some other “incidental sighting” of a migrant in some weird place – but not as weird as the Whimbrel (my only of the week) foraging at 4,200 feet atop Sugarloaf Mountain that Paul Doiron, Kristen Lindquist, and I observed on Sunday afternoon. While I knew they forage on mossberry during migration, such as in the bogs Downeast, I was most definitely not expecting one up here!

Therefore, with a total of 7 shorebirding locations – plus that mountaintop Whimbrel! – “this week’s shorebird high counts” scoreboard looks like this:

AMERICAN GOLDEN-PLOVER: 1 ad, Eastern Road Trail, Scarborough, 8/24 (with Jeannette).

Jeannette in Marsh_edited-1

Of course, it’s not just shorebirds that are on the move – there are plenty of passerines as well! A migrant Wilson’s Warbler and a whopping 14 Ruby-throated Hummingbirds were at Old Town House Park on Saturday morning when I visited it with my Saturday Morning Birdwalk group. My tour group to the Poplar Hut encountered mixed-species foraging flocks as we hiked to and from the hut, highlighted by an immature female Cape May Warbler in a little wave around the hut itself on Sunday morning.

Other highlights this week included 14 Wood Ducks and a bumper crop of juvenile Common Yellowthroats at Florida Lake Park (8/24), the whiter of the two Tricolored Heron x Snowy Egret hybrids (“Splotchy”) in the Rte 1/9 salt pannes in Scarborough Marsh with Jeannette on the same day and a drake White-winged Scoter off of Biddeford Pool Beach on 8/25.

While a diversity of shorebirds will continue for several more weeks (and there’s a better chance for Western, Baird’s, and Buff-breasted Sandpipers), I tend to spend less time focusing on them (and therefore not enough time at enough prime locations over the course of the week), and therefore only occasionally post summary totals. In fact, if the much-reduced numbers at Popham today are any indication, a lot of shorebirds departed with the passage of this recent cold front.

Instead, I spend most of my free mornings now at “my office,” the bridge at Sandy Point Beach, Cousin’s Island, Yarmouth, observing and obsessively counting migrant passerines in the “Morning Flight.” In fact, my first visit of the season there on Thursday morning yielded 438 migrants, including 17 species of warblers, 1 early Dickcissel, 1 Blue-gray Gnatcatcher (my 3rd-ever here), and 5 Prairie Warblers – my 2nd highest count.

(Much) more on that soon.
