It’s warbler season! This obliging Northern Parula was in the canopy surrounding the
Bradbury Mountain Hawkwatch on May 14th. You know the hawkwatching season is coming to a close when there are more species of warblers around the summit than migrant hawks tallied overhead!

My highlights over the past seven days included the following:

  • 12 species of warblers led by 40-60 Yellow-rumped Warblers and 10 Black-and-white Warblers, Florida Lake Park, Freeport, 5/8 (with Saturday Morning Birdwalk Group).
  • 17 species of warblers, led by 30+ Yellow-rumped and 9 Common Yellowthroats, Florida Lake Park, 5/11.
  • 1 Rusty Blackbird continues at Florida Lake Park through week’s end; regular in early May here.
  • 1 Warbling Vireo, our yard in Pownal, 5/14 (Yard Bird #131!)
  • 18 species of warblers led by 40+ Yellow-rumped and 19 Common Yellowthroats, Florida Lake Park, 5/14.
  • 1 Evening Grosbeak (with Noah Gibb) and 4 Lesser Yellowlegs (my 164th Patch Bird here!), Florida Lake Park, 5/14.

It’s on! My personal first-of-years and new spring arrivals included:

  • 1 Magnolia Warbler, Florida Lake Park, 5/8 (with Saturday Morning Birdwalk group).
  • 1 American Redstart, Florida Lake Park, 5/8 (with Saturday Morning Birdwalk group).
  • 1 Least Flycatcher, Florida Lake Park, 5/8 (with Saturday Morning Birdwalk group).
  • 1 Lincoln’s Sparrow, Garcelon Bog Conservation Area, Lewiston, 5/9.
  • 2 Bank Swallows, Bradbury Mountain Spring Hawkwatch, Pownal, 5/9.
  • 1 Rose-breasted Grosbeak, here at the store, 5/9.
  • 1 Great-crested Flycatcher, Florida Lake Park, 5/10.
  • 1 Solitary Sandpiper, Florida Lake Park, 5/10.
  • 14 American Pipits, Bradbury Mountain Spring Hawkwatch, 5/10.
  • 1 Eastern Kingbird, Bradbury Mountain Spring Hawkwatch, 5/10.
  • 1 Spotted Sandpiper, Florida Lake Park, 5/11.
  • 1 Wilson’s Warbler, Florida Lake Park, 5/11.
  • 1 Blackpoll Warbler, Florida Lake Park, 5/11.

Apparent “Krider’s” x “Eastern” Red-tailed Hawk, Pownal, Maine, 4/20/21

1 Reply

This stunningly pale immature Red-tailed Hawk passed over the Bradbury Mountain Spring Hawkwatch, sponsored by Freeport Wild Bird Supply, in Pownal, Maine on the afternoon of April 20, 2021.

Highly suggestive of the extremely pale “Krider’s” Red-tailed Hawk (a subspecies or quite possibly just a very pale color morph) from Central North America and with scattered vagrant records along the Eastern seaboard, we believe this individual shows features most consistent with an “intergrade” between the so-called Krider’s and our typical Eastern subspecies.

The very pale white head first brought my attention to this bird as it approached the summit from the north-northeast, and circled overhead and slightly behind the plethora of counters and observers on our biggest flight day of the season. Tova Mellen gets the award for the best photos – by far – and we appreciate her effort and willingness to share them. Thanks, Tova!

Andrew Sharp, Mathew Gilbert, and Charles Duncan also managed photos, and I was able to capture (poorly!) a few additional angles that show some helpful features.

The mostly-white head, very pale underparts, and lightly-marked underwings (especially the reduced patagium) all suggest Krider’s. However, the darker crown and fairly-dark spots on what would be the edges of the belly band are more suggestive of an intergrade.

The relatively bold white panel on the upperwings is also suggestive of Krider’s, but it’s not as bold and bright as many photos suggest. The back color is also brownish-gray. Both of these look to be more consistent with an intergrade.

The white uppertail coverts/lower rump area was more evident than this too-dark photo suggests, nonetheless, it does not seem white and broad enough to be a Krider’s. Unfortunately, the pattern of the uppertail was not decipherable.

The poor exposure of this photo makes the bird look much darker than it appeared in the field (looked more like Tova’s photos, above), but it does accentuate where the dark markings are and are not.

As for printed references, this bird looks to be a near-perfect match for the “Juv/1st Year Eastern x Krider’s Integrade on Page 66 of The Crossley ID Guide to Raptors.

We had limited views of the upperparts, but they did suggest the presence of fairly extensive white on the scapulars, the large pale window, and the narrow pale uppertail covert band as shown on page 293 of Raptors of Eastern North America by Brian K. Wheeler.

Therefore, we reached the tentative conclusion that this bird was an Eastern x Krider’s, but as with all subspecies and especially hybrid thereof, designations of Red-tailed Hawk, absolute identification is likely impossible. Fun bird though!

I’ll add any comments and feedback I receive here:

Brunswick-Freeport Christmas Bird Count: “West Freeport Sector,” 1/3/2021

3 Replies

On Sunday, Jeannette and spent the day participating in the annual Brunswick-Freeport Christmas Bird Count. For 14 out of the past 16 years, we have covered the “West Freeport” territory, which includes all of Freeport west of I295, with a corner of Yarmouth, a sliver of Pownal, and a notch of Durham.

As I have written about before, this suburban and exurban route covers a lot of ground. We walk miles upon miles of backroads, and we sample the public open spaces of Hedgehog Mountain Park, Florida Lake Park, and Hidden Pond Preserve. Our only waterfront is the Cousin’s River marsh complex, which was mostly open today – as were almost all flowing streams, woodland drainages, and the outlet channel at Florida Lake.  This was the most open water we have had in some time.

The weather was fantastic: after a chilly start, bright sunshine and virtually no wind made for a pleasant, temperate day, and aided detection. The lovely morning even led to singing from some of our resident species, especially White-breasted Nuthatch, and territorial drumming by Hairy Woodpeckers.

By doing this route consistently year in and year out, Jeannette and I can use it to compare winter seasons. We like to compare the tallies to test our preconceived notions of the season, and we can even use it as a sample to gauge seed sales at the store for the coming months! 2019 was a good example of that.

Yesterday, we did confirm several recent trends and hypotheses that we have seen so far this winter. Native sparrows including Dark-eyed Juncos are very low, woodpeckers are above average, and “winter finches” have really cleared out. Even Pine Grosbeaks are now diminishing, but the bulk of other nomadic species have either moved through (Pine Siskin; Evening Grosbeak) or are just not around in large numbers (Common Redpoll).

Meanwhile, the very mild fall and early winter has helped “half-hardies,” like our first sector records of Hermit Thrush and – finally a – Carolina Wren survive.  The minimal snow cover and mild temperatures usually keeps a lot of ground-feeding sparrows around through the winter, but this is not the case this year – low “weed” seed crops due to our summer-long drought continues to be my hypothesis. 

Fruit crops, especially crabapples, are being rapidly depleted as Pine Grosbeaks and American Robins have moved through en masse of late. It will be slim pickings for Bohemian Waxwings if they arrive.

But perhaps most relevant was the fantastic numbers of birds that make up our “mixed-species foraging flocks.”  I was surprised to tally only our average number of Black-capped Chickadees (310 compared to an average of 307.9), but Tufted Titmouse, Red-breasted Nuthatch, White-breasted Nuthatch, and Downy Woodpeckers were well above average (see below). Blue Jays were a little above average (but that number fluctuates widely based on acorn crops), as were Northern Cardinals.  Cardinals, Red-bellied Woodpeckers, and especially Eastern Bluebirds reflected their continuing steady increase as wintering species in the region.

These are also many of the most common and conspicuous visitors to feeding stations, and our survey correlated with what we have been hearing at the store all season. We also noted that neighborhoods with well-stocked feeders had far more birds than wooded parks, neighborhoods with few or no feeders, or other less developed stretches. Clearly, feeders and their supplemental food are important to our resident birds this year. And our bird seed sales, even after the massive finch flight of the fall has moved on, reflect that as well.

But yeah, our first-ever Hermit Thrush, Carolina Wren, and Pine Siskins, plus our first Ruffed Grouse in 11 years, and yeah, Pine Grosbeaks, were all nice, too!

Are There “No Birds Out There?” – A Day on a Christmas Bird Count as a Case Study.

2 Replies


It was a record year for Evening Grosbeaks in our CBC territory.

On Sunday, December 30th, Erin Walter joined me for the Freeport-Brunswick Christmas Bird Count (CBC). My annual territory covers most of Freeport west of I-295, with a small bite of Yarmouth, a sliver of Pownal, and a corner of Durham. It’s suburban and ex-urban, almost exclusively residential, and public open space is limited to Hedgehog Mountain Park and adjacent playing fields, Florida Lake Park, and Hidden Pond Preserve.

Like all of the CBCs I do, we walk…a lot. And this year was no exception. While the rest of the team abandoned me (the car was full just the day before!), Erin stuck with the deathmarch to its chilly end, and Jeannette (and Bonxie) covered the Hedgehog Mountain Park area in the early morning for us. With just a team of two for the day, Erin and I spent most of our time split up, dividing the length of roads we cover by walking mile stretches and leap-frogging each other with a car. Using that strategy, we cover a majority of the sector’s roads, and we cover it thoroughly: woodlots, fields, feeders, yards, etc, are all checked.

In the end, we walked up to 12 miles each, with a total of 17.5 miles covered by the two of us, and another 2 covered by Jeannette.  About 18 miles were covered by car. In other words, we spent most of the day outside, working each and every mixed-species foraging flock we encountered.

I have covered this sector for 13 of the past 14 years, and each year I have done it the same way. It’s nothing if not thorough as less than 8 hours of useable daylight can offer. Therefore, the 13 years of data provide an interesting little dataset, one that can be compared and dissected. That’s why I like to do this relatively unproductive (by coastal Maine standards) territory. And, this is why I am writing this blog today: because I think the consistency and standardization provides a way to contrast seasons more than just anecdotally.

With a cold – but not brutally so, it was -16F when we started last year! – and calm day, weather wouldn’t be a factor in limiting detections, so our count should be a little snapshot of “what’s going on out there.”  It’s a good way for me to collect data for my preconceived notions, or find out that I need to refute them. So what IS going on out there?

Total species were just below average for us, while total individuals were a little above average. Let’s try and break it down a bit.

After a very cold start to the winter, it’s been mostly above normal, and we’re down to just a patchy layer of icy snow. Some running fresh water is open, but most small ponds are still frozen. But our section has limited water, so waterbird numbers are uninspiring no matter what. The Cousin’s River Marsh west of the interstate was mostly frozen, and the little stretch of open water in the river was completely devoid of ducks. It’s a Sunday, so the Brunswick Landfill is closed, so we didn’t have the evening commute of gulls returning to roost on the bay to tally.

However, I know for a fact we cover the landbirds as exhaustively as anyone, and this is where the data gets interesting. Oak, beech, and White Pine nuts and seeds are virtually non-existent this year, as we all have been noticing. There’s not much spruce cone in our area either and very little Eastern Hemlock. Paper Birch and especially Yellow Birch, however, are in decent shape, as is Speckled Alder.  Ash seeds are in good supply.

With so little natural food resources overall, it was an extraordinary fall for bird feeding, augmented by the early cold and snow. Since then, however, it has felt like birds have “disappeared,” and many folks coming into the store are reporting slow feeding stations. Are there birds out there and just not coming to feeders? Or did everything move on? Or, is our perception simply wrong?  Erin and I wanted to find out.

As always, the answer differed between species. We had a record low for Blue Jays, more than 1/3 of average. Clearly, with the lack of acorns to cache, most of our Blue Jays simply moved on – those caches of Black Oil Sunflower seeds and peanuts they hoarded in the fall can only go so far. And we set a new record low for Rock Pigeons (0!) as they were all apparently at our store’s feeders outside our territory all day. And on some days of birding, you just don’t see a lot of raptors.

Woodpeckers were interesting. We were above average in Red-bellied (continuing their increasing trend in Maine) and Downy, but Hairys had their second highest tally – almost double average. They were also drumming more widely than usual for the end of the year; did that simply increase detection or are there more around this year, perhaps following a very good breeding season?

33 European Starlings was a new record high count for the territory. American Crows, Brown Creepers, Eastern Bluebirds, Northern Cardinals, and House Finches were all above average. The measly 5 American Tree Sparrows were a new record low, however, perhaps due to that early snowfall. Then again, Dark-eyed Juncos were well above average, so who knows?

Considering birch and alder are the only good tree seed crops around, we were not surprised to find an above-average number of American Goldfinches. Common Redpolls aren’t here yet, and the good numbers of Purple Finches and Pine Siskins from the fall have clearly moved on. However, the best winter for Evening Grosbeaks in at least 20 years continues – we had a new record high for the territory, with 2 in a yard on Hunter Road and 1 loner on Merrill Road in Freeport, and an impressive group of 26 on Webster Road, which Erin was able to extensively photograph.

But of most interest to me are the core members (joined by the woodpeckers and to a lesser extent some of the finches) of the mixed-species foraging flocks that travel our woods and pass through our yards. The “feeder birds and allies” if you will. The insect-eating Brown Creepers were above average, but Golden-crowned Kinglets were extremely low. I don’t have an explanation here, so I’ll concentrate on the seed-eating members of the flock.

We were interested to find that Black-capped Chickadees were just about average; they seemed low of late, making me wonder if they too moved further south this winter. Yet surprisingly, we had a new record high count for Tufted Titmice, more than doubling our 13-year average. Good breeding season, or do these resident birds not clear out when food resources are slim?  Both nuthatches were above average, but I was really surprised to find Red-breasted Nuthatches so common. I thought they too had continued on, but there was 1-2 with almost every flock we encountered.

But where we saw these birds was definitely telling. In an hour at Hedghog Mountain, Jeannette has all of 3 Black-capped Chickadees, 2 White-breasted Nuthatches, and 1 Red-breasted Nuthatch. Erin and I had absolutely nothing at Florida Lake Park.  Other stretches of mostly wooded habitat was very quiet. But in neighborhoods with well-stocked bird feeders? Lots of birds!  Although we didn’t necessarily see as many birds at feeders themselves as in and around yards that have them, I t’s clear that the supplemental food resources offered by people increases the number of birds in the area in winter. And on a relatively mild and benign day, they were mostly out feeding elsewhere – but we know where they’ll go as the pressure starts to drop this afternoon with the approaching storm.  And in contrast, while we had some goldfinches at feeders, we had most of them in birches and alders, even weedy areas –all natural food which is readily available at the moment, as opposed to many of the other tree crops.

So what does this all mean? Well, good question! And I don’t really know!  But clearly it’s not quite as “slow” out there as many bird watchers are reporting. While Evening Grosbeaks were rightly the star of the show today, I learned a lot about the current status of our “feeder birds.”  More questions and answers, as always, but I enjoyed the exercise of analyzing and postulating (i.e. pretending I am still a scientist). This small section of the state, on only one day, covered by only 2 people, can only tell us so much, but after 13 years of doing this essentially the same way, the numbers are easy to compare and contrast. And perhaps, after a handful of more years, we might even have a little fun with some trend analysis.

Until then, here’s our annotated checklist for the day (and yes, the taxonomy of my spreadsheet is woefully outdated). Averages are in parentheses.

Begin: 7:17am. 19F, mostly cloudy, very light NW.

My February Birding Re-Cap (2/16/15)

Leave a reply

I know it’s been a while since I’ve blogged, but I sure hope you have taken that to mean that I have not been out birding! Quite the contrary in fact.

Yeah, it’s been bitter cold – we’ve yet to rise above freezing in February! And if you hadn’t noticed, we’ve had quite a bit of snow recently. Of course, strong winds with dangerous windchills (like yesterday) and heavy snow precluded birding on some days -well, except for feeder-watching, which has been truly excellent.

In fact, the feeder-watching has been so good of late, that Saturday’s birdwalk outing was mostly spent watching feeders. 50+ Common Redpolls, Pine Siskins, Purple Finches, a Carolina Wren, and more were enjoyed from a sheltered yard, or from the inside of our house. Yup, we went indoors for the birdwalk this week, defrosting for about a half hour – our feeders are only visible from inside the house, afterall.

And with several snow days and work-from-home writing days of late, I have been enjoying our feeder activity: a large number of American Goldfinches have been joined by varying small numbers of Pine Siskin, Purple Finch, and Common Redpolls. Still waiting for a big flock, however. And the second-ever, and first long-staying, Carolina Wren in the yard has been a treat – we’re pumping him full of mealworms to keep him around, and healthy.
IMG_9420_edited-3

The feeders at the store have been active, as well, although non-goldfinch finch numbers have not been as good or as consistent at home. But, for mid-winter with this much snow on the ground, the diversity has been surprisingly good. (Weekly totals are posted to our store’s website).

Snowy Owls are around, and on 1/31 we finally added one to our all-time Saturday Morning Birdwalk list with a visit to Brunswick Landing: species #236. Meanwhile, our birdwalk to Winslow Park on 2/7 had Barred Owl, the continuing (despite all the ice) over-wintering Dunlin (12), and the 4 Barrow’s Goldeneyes (3 drakes and 1 hen) that had been present.

But the impressive ice cover in Casco Bay has greatly reduced the amount of waterfowl in the immediate vicinity over the last couple of weeks. The end of Winslow remains clear (barely) and the duck concentrations there are quite good, but as of today, however, the much-reduced area of open water now held only two drake Barrow’s Goldeneyes. Meanwhile, the small hole of open water at the base of the Lower Falls in Yarmouth is still somehow still hosting the merganser “hat-trick” (with varying numbers of all three species) as it does every winter – they’re running out of room though!

IMG_4852_MALLs,RiverbankPark,2-10-15_edited-1

IMG_4862_edited-1
Not all ducks are quite as concentrated as these hungry Mallards (with a few American Black Ducks) at Riverbank Park in Westbrook.

While the field trip portion of my Gull Identification Workshop has been postponed for the last two Sundays, gull-watching is pretty good right now, especially in and around Portland Harbor. Hatch Hill Landfill in Augusta on the 12th, however, had only about 100 Herring Gulls – gull numbers are drastically reduced here when there is little open water on the Kennebec River in downtown. The Bath Landfill is hosting a few Iceland and a couple of Glaucous Gulls, however.

Frugivores have been common, with large flocks of American Robins and goodly numbers of Cedar Waxwings stripping all available, palatable fruit. Bohemian Waxwings have been scattered about – although I have yet to catch up with any – but so far Pine Grosbeaks have mostly remained to our north. The rapidly diminishing fruit crop locally will likely concentrate these birds further, or push them southward.

My two best days of birding this month, however, were on Feb 1 and just this past Friday. On the 1st, a snowshoe at the Waterboro Barrens Preserve was awesome. I went there to refind the Red Crossbills that a friend and I had there in December, as my recordings from that visit were inconclusive as to “type.”

Not only did I find 14 crossbills, but many were in full song, and one male was apparently carrying nesting material! A light wind, and my huffing-and-puffing from snowshoeing in waist-deep snow drifts off trail, impeded the clarity of my recordings, unfortunately. However, one of the call types (as analyzed by Matt Young over at Cornell) was suggestive of the Type 8 Red Crossbill from Newfoundland, which has yet to be definitively recorded outside of that province. Intriguing -yup, I need to find time to go back and improve the recording.

The icing on the cake that day was a Hoary Redpoll teased out from a flock of about 40 Commons as they alighted in fed in the Pitch Pines with the crossbills. This was my first Hoary in Maine away from a feeder.

With all of these storms, and two “nice” days of northeasterly winds, I had alcids on my mind as Lois Gerke and I spent the morning in Cape Elizabeth on Friday (2/13). Apparently, my hunch was correct – we scored 4 species of alcids! This is not an easy feet in winter in Maine, although I have hit the total several times (not yet hit 5, however). Black Guillemots were scattered about, as usual, but the fun started with a fly-by Dovekie at Dyer Point.

A continuing (and apparently not very healthy) Thick-billed Murre was at nearby Kettle Cove.
L1010192_TBMU,Kettle_Cove,2-13-15_edited-1

Our presence likely saved its life for now, as a 4th-cycle Bald Eagle had its eye on it – but also, us, apparently. The eagle even landed on the rocks a few inches from the murre, which, instead of diving to escape as a healthy alcid would, was apparently resigned to simply tucking itself into a corner of the rock.

L1010189_BAEA2_4thCycle,Kettle_Cove,2-13-15_edited-1

After checking for frugivores at Village Crossings (just a few American Robins on what was left of the crabapple, but we did enjoy a flock of 22 Common Redpolls), we decided to try for a Razorbill for our fourth alcid of the day. Lois’s time was limited, so instead of heading back down to Dyer Point (where the wind was also brutal), we rolled the dice and tried Portland Head Light. And sure enough, a Razorbill was offshore, feeding at the mouth of Casco Bay on the changing tide!

After lunch, I decided to procrastinate a little longer and slowly bird my way to the store, checking for open water on the Falmouth Foreside coastline. Although I was looking for duck concentrations, once again, alcids stole the show: a Thick-billed Murre flew into the cove on the south side of the Mackworth Island causeway. Perfectly strong and healthy, this bird was likely following some small fish into the bay on the incoming tide.

Even more surprising was another Thick-billed Murre in Falmouth, even further up the bay off of the Town Landing. This bird also looked fine, swimming steadily upstream with the tide, “snorkeling” to look for food.
L1010236_TBMU,FalmouthTownLanding,2-13-15_edited-1

L1010218_TBMU_wBUFF,FalmouthTownLanding,2-13-15_edited-1
These Buffleheads looked just as surprised as I was.

So yeah, a 4-alcid day, with three different Thick-billed Murres in quite a day, and probably one of my best birding days of the winter. It just goes to show you what winter birding can bring in Maine, even during an impressive deep-freeze. So yeah, I’ll be out birding as much as I can, and signs of spring are certainly in the air: woodpeckers are drumming actively, Tufted Titmice and White-breasted Nuthatches are singing frequently now, and Great Horned Owls are already nesting. Bald Eagles are probably starting some house-keeping, Common Ravens are reaffirming territories, and in only a month, the Bradbury Mountain Spring Hawkwatch gets underway!

Until then, it’s finches, ducks, white-winged gulls, frugivores, and alcids. I’ll be out in the field, and I hope you will be too. (And don’t forget, you can check out what I have been seeing in near-daily posts to our store’s Facebook page).

2014-15 Freeport-Brunswick CBC: West Freeport Territory.

1 Reply

The Freeport-Brunswick Christmas Bird Count (CBC) was conducted on Saturday, January 3rd. With the exception of the last two winters in which we were away visiting family during the count, Jeannette and I have taken part in the count since 2004.

In our first year, as newcomers to the count, we were assigned the least-popular “West Freeport” territory, which includes all of Freeport west of I-295, a corner of Yarmouth and Durham, and a sliver of Pownal. With open water (in some winters) limited to a small stretch of the Cousin’s River and Pratt’s Brook and adjacent brackish marsh, the territory doesn’t get the diversity of the other sections, that include productive places like Cousin’s Island, Winslow Park, and Harpswell.

While Hedgehog Mountain Park and Florida Lake Park are included, these are not usually very productive places in the middle of winter. But I still enjoy being able to cover two of my favorite patches, plus our own backyard (which makes for a good excuse to take a mid-day break for a hot lunch while counting at our feeding station). But in order to adequately sample this large area, with lots of yards, woodlots, and scattered fields, adequately, Jeannette and I spend a lot of time walking.

And whether it’s a CBC or any other birding, I always prefer more time walking than driving. So instead of driving all of these suburban and exurban roads, we walk them. And we walk a lot. Leap-frogging each other with the car, walking one mile stretches at a time, we walk about 20 miles (about 11-12 miles each) in all, and drive only 18-20. In doing so, we pass by a lot of feeders, and encounter mixed species foraging flocks that we would most likely never detect by just driving around.

And so we count a lot of birds. We sift through hundreds of Black-capped Chickadees as we pick out the other members of the winter flock. We listen for finches, check out feeders, and otherwise just go birding! This is how I like to CBC!

One of the other things I particular enjoy about covering this territory is that I am able to quantify some of my impressions of the winter’s birding that I have been noting walking Sasha at the ‘Hog, or watching my own feeders, and just while birding in general.

This year, a lack of snowcover made for easy walking, but reduced concentrations of birds, especially at edges and feeders. Some of the impressions that I have had turned out to be true: although feeders are often a little slower than usual, there are plenty of birds around. Red-breasted Nuthatches are abundant, but Golden-crowned Kinglets are nearly absent. Irruptive finches are still in short supply, but I expect them to now increase as winter returns. There also seem to be a lot of Red-tailed Hawks around, Wild Turkeys and Red-bellied Woodpeckers continue to increase, and the daily “commute” of gulls overhead (which I often note from the yard and Florida Lake Park in particular) no longer occurs following the closing of a feed lot in Auburn (gulls used to travel from Casco Bay to and from this and other Lewiston-Auburn feeding locations).

Dan Nickerson joined us this year, also welcoming the opportunity to bird his neighborhood as well, and making sure his feeder birds get counted. And we really lucked out with the weather. It was indeed the calm before the storm, with light winds all day and the first flurries not falling until we were at the wrap-up in the evening. It was cold though: 10F to start, with a high of only 21F. Increasing humidity and cloud cover made for a very raw afternoon, and a bone-chilling day. That lunch break at our feeders was a necessary respite today, as was some hot chai.

Due to the complex geography of the circle, we actually have two compilers, and two compilations, splitting the long peninsulas of the eastern edge off from the rest of the circle. Therefore, we usually speak of the western half of the circle (nicknamed “The Bean Count”) when comparing our numbers. Of the western half teams, we tallied 9 high counts, and had the only Common Redpolls, White-winged Crossbills, and Northern Shrike of the parties in our area.

The bird of the day was definitely the four White-winged Crossbills that Dan and I had departing a feeder on Beech Hill Road in Freeport. Jeannette and I were very excited to find a shrike at Hidden Pond Preserve where we also hope to see one, and hopefully the two Common Redpolls that flew over us on Granite Road in Yarmouth are a sign of things to come.

But my highlight was the Red-bellied Woodpecker that Dan and I found along Hunter Road. As we were coming up onto the Hunter Road Fields, the Red-bellied called and we spotted it at the edge of the road. I greatly amused Dan, apparently, as I sprinted across the road, got my feet onto the Hunter Road Fields property – which is part of my Hedgehog Mountain Patch List area – and logged the Red-belly for my 148th Patch Bird! …A long overdue, border-line nemesis patch bird at that!

Good conversation throughout the day, and Stella’s chili at the wrap-up at the store, were icing on today’s frosty cake. While our crossbills were one of the best birds of “The Bean Count” area, one could argue the Snowy Owl found at Brunswick Landing would take the crown. 31 Northern Pintails in the “Winter of the Pintail” at Simpson’s Point may have been the most unexpected, along with a Common Grackle in Brunswick, and two Barrow’s Goldeneyes were other highlights.

Because Jeannette and I conduct the CBC with such a consistent route and methodology, I find it unusually valuable to compare data from year to year. Therefore, as I offer the list of this year’s sightings, in parenthesis, I also offer the average for our territory. An *asterix signifies a new record high for our territory.

The “West Freeport” section of the Freeport-Brunswick CBC doesn’t offer the rarities of the “Moody” section that I annually cover on the York County CBC, nor does it offer the intrigue and surprises when I cover the Portland Peninsula on the Greater Portland CBC. However, this is our “home field” CBC, and with thorough coverage, we quantify a nice sample of what occurs away from the shorelines in the winter. I look forward to learning more, counting lots of chickadees, and getting my exercise on next year’s CBC.

Three Days of Migration Watching in May -Day and Night.

In my blog last Wednesday, I made some prognostications about what we might expect for birds in the coming days. Let’s see how I did so far.

Rain began to fall Wednesday evening, and continued, heavy at times, through Thursday morning. With a persistent easterly wind, overnight migration was non-existent. In the rain on Thursday morning, Katrina and I checked out Florida Lake Park, but found only about 20 Yellow-rumped and 10 Palm warblers – fewer than in recent days. The local River Otter pair, however, put on a great show. Nothing new under the feeders at home (or at the store), either.

Afterwards, I took a spin through the local farms and fields, but found nothing out of the ordinary; it’s too early for most shorebirds anyway. Admittedly, however, I had vagrants on my mind (and still do! As usual). Although the southerly winds conducive to southern overshoots (as I discussed in the aforementioned blog) had yet to kick in, the deep easterly flow that we have been ensconced within could offer up its own surprises. With reports of the “largest incursion of Icelandic/European birds to Newfoundland in recent memory,” including amazing tallies of European Golden-Plovers, 9 Black-tailed Godwits, North America’s 4th (or so) Common Redhank…yeah, the “Rarity Fever” in me can’t help but kick up. Perhaps something will ride one of those Iceland-Portland cargo ships that are in service these days!

Light rain continued through Thursday morning, diminishing to drizzle and fog until the afternoon, when a shift to westerly winds began to clear things out. Overnight, light and variable winds suggested a good migration should occur, but the radar wasn’t showing more than a light flight.
1am radar, 5-2-14  1am velocity, 5-2-14

However, it was foggy for much of the night, and fog can obscure the image of birds on the radar, especially if they are flying low. “Birding by radar” is not infallible, and I had a feeling it might have been a little misleading this morning. A steady trickle of Yellow-rumped Warblers moving over the yard at dawn confirmed this. The weather was just too-not-terrible for there not to be a lot of birds on the go.

So off to Florida Lake I went.  And, for a change this spring, I was not disappointed.  100+ Yellow-rumped Warblers, 20+ Palm Warblers, my first Northern Waterthrush and Black-throated Green Warbler (finally!) of the year, a singing migrant Greater Yellowlegs, and much, much more. I caught the lingering pair of Green-winged Teal copulating; are they going to breed here? Ring-necked Ducks had increased to 16 and there is still a pair of Common Mergansers here.

As the fog burned off, the sun shone brightly, and heat began to rise in swirling thermals, hawks took to the skies on the light westerly wind. I had to pull myself away from the hawkwatch kicking and screaming at 12:30, but by then we had eclipsed (at 10:35) our all-time record count of 4,474 birds when a Merlin streaked by. 388 Broad-winged Hawks and 22 Sharp-shinned Hawks were included in the total of 429 migrant raptors when I departed.

Last night’s passerine migration – yup, the fog on the radar definitely obscured the intensity of the flight! – was still evident well past noon, as Yellow-rumped Warblers were still on the go, reorienting inland after last night’s flight. Well over 200 had passed the summit by the time I departed, as did my first two Chimney Swifts and Eastern Kingbirds (also 2) of the year. And by day’s end, 705 raptors led by 583 Broad-wings were tallied, adding to our record totals. Around 4:00pm, our 5000th raptor had passed – a milestone we never thought we would reach.

Come nightfall, the radar was active once again.  Here are the 1am reflectivity and velocity images for example:
1am radar, 5-3-141am velocity, 5-3-14

Notice the dark greens in the center of the return, but overall the rather narrow diameter of the image?  My guess is that mostly overcast skies and a light westerly winds, perhaps including some turbulence from the passing cold front, kept birds low once again.  But, without fog around, it was certain that this was birds – confirmed by the distance SW-NE pattern of the velocity image, and its speed. I think it was actually a lot of birds.

And come morning, Yellow-rumped Warblers were overhead as I stood on the back porch at dawn, and the Saturday Morning Birdwalk group and I headed over to Florida Lake.  Yeah, it was good.  Very good.

In the past few days, we’ve also finally had the first couple of reports of Ruby-throated Hummingbirds and Baltimore Orioles, so that those have just begun to arrive.  As I mentioned the other day, food is in short supply for these backyard favorites, so feeders are going to be important for the first arrivals.

But no vagrants from the south, or East …yet!
