Winter Window Watching Part II.

1 Reply

This adult male Sharp-shinned Hawk was our fourth individual “Sharpie” identified at our feeding station this winter.

With the dreadfully slow pace of recovery following shoulder surgery, my birding these past three weeks was once again mostly outside our windows here at our home in Durham. One unseasonably mild week was followed by a week of below normal temperatures and several snow events. Then, the period finished out with spring-like feel. It was fascinating to track the ebbs and flows of feeder activity with each change in the weather and the progression of the season.

Highlights over the last 3 weeks:

  • 2 Red-winged Blackbirds (First of Year), our feeders in Durham, 2/23.
  • Continued Sharp-shinned Hawk saga at our feeders.
  • Scattered Turkey Vultures and more Red-winged Blackbirds returning the area in the second week of March.
  • 1 hen Barrow’s Goldeneye, Bernard Lown Peace Bridge, Auburn/Lewiston, 3/7 (with Jeannette).
  • 3 1st-winter Iceland Gulls, Auburn Riverwalk, 3/7 (with Jeannette).

Compared to the previous weeks –which I summarized in my last blog – unseasonably mild weather and a rapidly diminishing snowpack, activity at the feeders here in Durham continued to decrease during the week of the 2/13. The mixed-species foraging flocks had mostly broken up already, so it became harder to tell how many of each resident are around. However, a female Red-breasted Nuthatch rejoined our overwintering male, and we do have at least 12 Black-capped Chickadees now. There still seems to be two pairs of Tufted Titmice, but they no longer tolerate each other’s company.

Eastern Bluebirds (down to a pair daily) and Northern Cardinals (down to two pairs) decreased, but there was a noticeable increase in Dark-eyed Juncos this week: I saw around 20 under the feeders on 2/19 (up from 10-16), but there were more in the bushes. We have a little “evening flight” where the juncos leave our yard and scrub, fly down our driveway, and across the street into woods with thicker evergreen cover to spend their winter nights. I counted 34 that day as they departed the feeders and the woods behind it. With more bare ground, a lot of our ground feeders (also including Mourning Doves) were not frequenting the feeders as much, as expected.  We still had 5 American Tree Sparrows and 2 White-throated Sparrows, however, carrying over from last week.

Signs of spring were everywhere. I caught a pair of Mourning Doves copulation on the 19th, and I began to see daily Canada Goose flocks moving between the river and the opening nearby farm fields. Common Mergansers returned to the Androscoggin River across the street from our property the next day. Woodpeckers were drumming more this week, and birdsong noticeably increased.

Then came the snowfall on the 23rd, and the accumulation brought a renewed surge of activity to the feeders, and a return to winter. The highlight was my first two Red-winged Blackbirds of the year, adding more color to a birdy day. Northern Cardinals jumped back up to 7, American Tree Sparrows increased to 10, and a third White-throated Sparrow arrived. Mourning Doves increased to 24, Eastern Bluebirds were back up to 7, and 3 House Finches returned.

 Other than the Red-wings, these are mostly local birds that had begun to spread out, but returned to the supplemental food with the fresh snowfall. There did seem to be a legitimate increase in Dark-eyed Juncos that week, however, which may have included some early migrants. Meanwhile, 30-40 American Goldfinches continued daily, although once again we were sans winter finches except for a single female Purple Finch on the 21st.

Now, with a return to some significantly cold temperatures and more rounds of snow, I expected feeder-watching to be excellent during the week after that first storm. And sure enough, three bitter cold mornings followed by two more bouts of snow resulted in increased feeder activity overall yet again.

We continued to see 16-20 species a day at the feeders, although the wintery week pumped the breaks on new arrivals. Last week’s Red-winged Blackbirds likely turned back around when the snow began to accumulate, for example. A small bump in daily counts of Dark-eyed Juncos and American Tree Sparrows could involve some northbound migrants, but probably more likely were local birds concentrating again as snow piled up. Our 3 White-throated Sparrows continued. There was a definite uptick in American Goldfinches, however, with a high count of 46 on the 28th. 

We saw fewer Eastern Bluebirds, Northern Cardinals, and Blue Jays most days that week compared to weeks prior, likely as these birds start setting up territories and/or begin to disperse. Lots of Hairy Woodpecker drumming and Tufted Titmouse singing this week, too, despite the return to full-on winter weather. Our lone overwintering male Red-breasted Nuthatch has also become less frequent.  Unfortunately, 2-5 European Starlings became more regular – come on Sharpie, help me out here!

On Saturday the 4th, 12.5 heavy, wet inches accumulated here in Durham, burying our brush pile once again. Not surprisingly, ground-feeders didn’t appreciate that very much, especially with the continuing Sharp-shinned Hawk activity. Two “Sharpies” were present this week (see below) both an adult male and the return of a sub-adult male. Our brush pile is critical -as it often is in open areas and following new construction – for birds’ safety, and when buried under snow, it didn’t have a lot of accessibility to hide.

On the 5th, for example, the subadult male was seen for the first time in a few weeks, and after just missing a Tufted Titmouse diving off the feeders, it perched conspicuously next to the brush pile for over an hour. The next day, the adult male was staking out the feeders during my prime feeder-watching time of the morning, dramatically reducing my day’s tallies once again. There were times this week when the only bird in view out the window was a Sharp-shinned Hawk!

As the weather improved and snow began to melt rapidly as the week went on, Dark-eyed Juncos and Northern Cardinals in particular returned to previous weeks’ highs, finding safety when necessary in the brush pile once again. American Tree Sparrows had decreased to only 2 by week’s end, however, this may reflect the season more than anything; tree sparrows are among our first birds to start heading back north. Overall though, daily averages were down, but when all was said and done, the week’s high counts were very similar to previous weeks for most species.

Eastern Bluebirds have been fewer this week, likely as birds begin to disperse to breeding territories. And I have officially lost control of counting the number of Black-capped Chickadees and Tufted Titmice that are now visiting as they come randomly now instead of as a tight-nit mixed species flock(s) as they do in the winter. Another sign of the season was the arrival of 5 male Red-winged Blackbirds this morning (3/10), our first here since one on 2/23.  Now, it’s possible they are here to stay.

In addition to marked changes in the weather, daily activity and consumption ebbed and flowed with Sharp-shinned Hawk presence and activity as I mentioned above. I would say my most fascinating observations this constant feeder-watching vigil provided was the Accipiter drama. I am sure this is happening everywhere, all of the time, but my unusual observation duration and frequency offered the rare opportunity to study the predator presence.

The adult female that has been present most of the winter and has provided much of the said drama continued to be spotted in the yard through the end of February. However, much to my surprise, yet a different bird was present on a couple of days during the week of the 27th: a new adult male. This makes the fourth different Sharp-shined Hawk that we have hosted this winter.  Then, during the snowstorm on the 4th, a poor view of a Sharpie strongly suggest the subadult male that I saw only one day about three weeks prior. The saga continues! That ID was confirmed the next day, and he was seen repeatedly for the rest of the week. The adult male was also spotted a few more times through at least the 6th.

A second-winter male Sharp-shinned Hawk also returned to the scene this week.

Meanwhile, at the store in Freeport, two Red-winged Blackbirds that first appeared on the 19th increased to 7 during the snow, and a second Song Sparrow joined our single overwintering individual that week.

I have started to spend some time at the store in my continued limited-capacity, enjoying the feeder activity there was well. I was treated to the most activity that we have had there in a while on the 3rd, for example.  We need our local Cooper’s Hawk to return as the Rock Pigeon flock is building again. But unlike at home, Red-winged Blackbirds continued, with 2-3 still present from a high of 7.  We had a surge of American Goldfinches (from only 2-4 for most of the last few weeks to 12+.  Our single overwintering Song and White-throated Sparrows continue, and 4 Eastern Bluebirds are now regular.  I also welcomed back to work that day by a flock of 12 Cedar Waxwings descending on our Highbush Cranberry in the yard – a most welcome visit from one of my favorite birds!

And yes, I got out for a little birding this week, finally, as Jeannette and I visiting Auburn’s Little Andy Park and the Riverwalk, catching up with a few continuing winter birds: 1 Barrow’s Goldeneye and 3 Iceland Gulls. And when I was out and about this week (mostly being driven to and from appointments!), the renewed presence of Turkey Vultures was readily apparent.

I will be out birding a little more next week, but based on my visit with my surgeon yesterday, it looks like I’ll be forced to focus on feeder-watching for a while longer. Stay tuned!

A Month of Birding Out the Window.

Sharp-shinned Hawk drama has been keeping me entertained for the past month.

For the most of the past four weeks, my birding has been exclusively at our feeding station at our home in Durham as I recover from shoulder surgery.  We designed our house to maximize feeder- and yard-viewing opportunities, and I am sure thankful that we did! It will come as no surprise to anyone who knows me that I don’t sit still well, so my extended feeder-watching sessions have been both mentally and physically therapeutic. It has also been quite productive! And keeping track of daily numbers has been quite elucidating.

Despite our new construction being completed (well, mostly!) in October and virtually no landscaping occurring, we have been very pleasantly surprised by the diversity and activity – a reflection of the quality of the habitat on our property (and hence why we purchased it).  Nonetheless, I did not expect to be hosting 19-22 species a day at the feeding station in our first winter!

My feeder-watching vigils began the day after my surgery, on January 19th. The ebbs and flows during that first week were quite insightful. With three storm systems and snow piling up, the daily changes were noticeable, and mostly predictable. Our feeders were busiest with 22 species on 1/23 as over 14”of snow accumulated here in Durham. Numbers of ground-feeders peaked that day, with the week’s high counts of Mourning Doves (27), American Tree Sparrows (9), Northern Cardinals (11-12), and White-throated Sparrows (3). The 22 Dark-eyed Juncos was down a bit from a high of 25 following the first snowfall on the 20th.

Despite adding a third platform feeder, some ground-feeders had moved on by week’s end: 24 Mourning Doves, 14 Dark-eyed Juncos, 10 Northern Cardinals, and only 1 White-throated Sparrow remained, although American Tree Sparrows bumped back up to 9 with the snowfall of the 25th.

Eastern Bluebirds, meanwhile, had been increasing, with 4-6 daily becoming 14 by week’s end. Two House Finches became 5; they often travel with bluebirds in winter, so their simultaneous rise is not surprising. A single European Starling on 1/24 was unwelcome.

We picked up a second Red-breasted Nuthatch by week’s end, while one each of Red-bellied Woodpecker and Carolina Wren continue.  Resident woodland birds that travel together in a mixed-species foraging flocks are notoriously hard to count, as it’s often impossible to know whether you are looking at the same flock or multiple flocks as they come and go throughout the day. Therefore, we are left to take the daily “high count” (maximum number of birds seen at one time) only as our “total,” so trends are harder to detect. My high count of Black-capped Chickadees did increase from 6 to 10 by week’s end, however, while a pair of White-breasted Nuthatches, 2 Downy Woodpeckers, 2-4 Hairy Woodpeckers, and 4 Tufted Titmice remain the same.

We also have a single American Crow that visits daily, an irregular visit from a male Pileated Woodpecker, and I’m trying to get a feel for the wide variation in daily Blue Jay high counts (between 1 and 10).

The only disappointment so far this winter had been our finch diversity so far. A single Pine Siskin 1/19-20 and female Purple Finches during the storm on the 23rd were our only non-goldfinches in that first week. However, our American Goldfinch flock has more than made up for it with between 32 and 74 (1/25).

But speaking of finches, the “birds of the week” those first seven days were 5 fly-over Pine Grosbeaks on the 25th. Bald Eagles and a Red-tailed Hawk regularly fly past the windows, as does the daily commute of Herring (and a few Great Black-backed Gulls) moving up and down the Androscoggin River; hoping to tease out a white-winged gull for the yard list. We’ve also had a small flock of American Robins (up to 18) feeding on Winterberry and Multiflora Rose in the past few days.

By the second week, a relatively deep, now-frozen snowpack, and only a couple of weak weather systems, resulted in less daily variation in the numbers at our feeders here in Durham. Fluctuations in counts had more to do with the day’s weather and the presence of a Sharp-shinned Hawk (see below), rather than the seasonal movements of species as had occurred with the onset of “real winter” the week prior.

A lot of species counts stabilized, such as the daily average of about a dozen Eastern Bluebirds and up to 46 American Goldfinches.  However, some changes were noticeable, especially the ebbs and flows of ground-feeders: 6 American Tree Sparrows increased to 9, as many as 24 Dark-eyed Juncos decreased to 14, and after entertaining a third White-throated Sparrow for a couple of days, we are back down to two.

An impressive 13 Northern Cardinals on 1/29 was a seasonal high count, but otherwise most counts of the 18-21 species each day remained about the same. I had still not confirmed the presence of a second mixed-species foraging flock, for example, and our only finches remain the aforementioned impressive number of American Goldfinches and 4 House Finches. 

Since my “observation week” begins on Saturdays, Week 3 began the morning of February 4th with some extreme cold weather. And, wow, that was some cold!  Wind chill records (e.g. -45F in Portland and an astounding -108 at Mount Washington) Friday night into Saturday were thankfully short-lived. Here at our home, our windchill was “only” -21 on a low of -16F, as our anemometer was not receiving the full force of the wind.

The short duration of the cold snap – as extreme as it was – didn’t seem to have much impact on feeder birds, especially as the rest of the week’s weather was rather benign. Our Carolina Wren made it through, and overall activity and diversity was similar to last week (scroll down for previous posts). 

American Goldfinches slowly declined at our feeders this (from 46 to a low of 22), likely as our birch crop is being picked clean. Sparrows were up again, however, with 15 American Tree Sparrows now after starting the week with 6.  Dark-eyed Juncos spiked again to 20 on 2/5-6 before settling back down to 18; three more than we started the week with.

A female Purple Finch returned, and a Brown Creeper was now spotted daily in the trees immediately behind the feeding station. And a single Wild Turkey has returned to the feeders after being absent since early winter. Unfortunately, a pair of European Starlings were now present.

Two noticeable declines this week were in Northern Cardinals (from 11 to 7) and Mourning Doves (from 28 to 14). Meanwhile, Eastern Bluebirds have been far less frequent at our feeders as the week went on. This is all likely the result of direct and indirect (disturbance) effects of the continuing Accipiter saga. Daily high counts of other species were similarly affected by the presence of two different Sharp-shinned Hawks this week (see below).

Not surprisingly, the spring-like weather (including two days of record warmth) and very little precipitation reduced overall activity at the feeding station during Week 4, beginning on 2/11. We now have some bare spots on a slope now, where birds have been foraging, and the snowpack is much reduced in the woods. There’s more natural food available and less calories burned, so there’s less need for supplemental food – it’s long past time to put the “dependency on feeders” myth to bed!

Nonetheless, this week saw another uptick in Mourning Doves (high of 27) and American Tree Sparrows (of 10). Dark-eyed Juncos returned to a high of 21, but they have been spending as much time on the bare slope of our berm then at the feeders.

Eastern Bluebirds have been much less frequent this week, with a high of only 3 and they’re not visiting everyday. Same for the House Finches they usually travel with in winter –it’s just a sporadic pair now. American Goldfinches, however, remain strong, with a high of 32 this week. Our latest singleton Purple Finch has apparently moved on.

Winter flocks are breaking up, and that’s likely why the bluebirds have been less frequent; they might be spreading out already. The mixed-species foraging flock of residents are breaking up as well, and “bickering” is increasing among them, especially the Black-capped Chickadees. Meanwhile, Hairy Woodpeckers are courting now, and territorial drumming is frequent.

And then, with temperatures spiking to over 50 degrees on the 16th, Jeannette had the first Red-winged Blackbird of the year flying north overhead!  Already. I expect diversity and daily counts to change more often in the coming weeks now.

Meanwhile, birdwatching is not just about counting, so I kept notes of interesting observations and behaviors through the duration of my time stationed in front of the window (and short walks up and down the driveway, weather and ice permitting). I enjoyed seeing the slow but sure progression of the season, as Downy and especially Hairy Woodpeckers became more territorial, and male Hairys especially began drumming, accelerating this week. A pair of Common Ravens was regularly observed, with pair-bonding flight displays increasing. Tufted Titmice and Black-capped Chickadees began singing more, too.

I’ve also conducted an experiment with some suet products that we may bring into the mix at the store. None of which, however, has come close to being as popular as our current offerings, however.

A few of my most interesting behavioral and natural history observations were:

1. 1/28: I watched a Dark-eyed Junco that was foraging along our foundation grab a large cutworm-like-caterpillar and smack it on the snow. As it began to eat it, a bluebird flew down and grabbed the caterpillar. I had not observed kleptoparasitism in bluebirds before!

2. 2/2:  The male Sharp-shinned Hawk that has been hanging around was pursued and killed by a second accipiter that had been undetected by us. The brutal end to the chase took place within 10 feet of me. It was quick, I was in shock, neither a camera nor binoculars was within reach of my working arm, and I was afraid to move as I didn’t want to disrupt the proceedings – it’s the worst feeling to flush a predator from its hard-earned prey and see that prey item suffer and go to waste. 

The thing is, I think the only-marginally larger predator was actually an adult female Sharp-shinned Hawk as opposed to the far more likely adult male Cooper’s Hawk. Cooper’s Hawks are known to kill Sharpies, but I am unaware of published accounts of cannibalistic Sharpies. It all happened too quickly, and accipters are much easier to identify in flight three miles away than when they are sitting in front of your face (at least as adults). Apparently I was too traumatized by the event (and/or slowed mentally by painkillers) to look at details of face pattern. But the relative size and the paler chest and less steely-back were highly suggestive of an adult female Sharp-shinned.  Hopefully, it will take up the territory and I will be able to confirm its ID circumstantially.  But it was a rather violent end to my feeder-watching week!

Although only circumstantial evidence, an unequivocal female Sharp-shinned Hawk was spotted (and positively identified!) the next day thereafter, leading credence to the rare cannibalism theory. It’s only circumstantial evidence, but I have little doubt this is the bird that took the male the prior day. Furthermore, I have not seen a Cooper’s Hawk here all winter. Absolutely fascinating, and I wish I had photos to document the gruesome event.

The plot thickened even further on the 8th, when I spotted (and photographed this time) a second-winter male (subadult) Sharp-shinned Hawk hunting the feeders in the morning.  He better be careful out there! The woods of Durham are unforgiving!

The next week, I didn’t see him as only the adult female was around.

3. I’ve been sorting through as many of the daily commuting gulls as possible, and finally on the 15th, I picked out an Iceland Gull for our 122nd Yard Bird!  Interestingly, it was an adult or near-adult, different from the 1st winter birds that have been frequenting the Lewiston-Auburn riverfront a few miles upriver.

For almost three weeks, I left the house or driveway exactly three times (a follow-up appointment, a field trip to see Avatar, and a successful chase of the Common Ringed Plover at Timber Point in Biddeford on 1/31. Jeannette dumped me in the car and we drove down – me fully reclined and with an icepack strapped on. The bird was present as we arrived, and since the word was just getting out, we even had a parking spot. She set me up behind the scope (I had to ask a fellow birder for assistance in moving it!) and then took some photos.  I was pretty uncomfortable on the way home – to put it lightly – but it was absolutely worth it!

It wasn’t until Monday, February 6th (just under three weeks since my surgery) that I went out for a little birdwalk with Jeannette at the Auburn Riverwalk. It was a lovely day, and it was fantastically birdy!  We found a hen Northern Pintail amongst nearly 500 Mallards, and had three 1st-winter Iceland Gulls – the most I have had here in several years.  The overall bird activity was quite a bit above average, as the cold snap finally put some ice on the river and helped to concentrate birds here. Unfortunately, we did not see the Harris’s Sparrow in Turner before my body had enough of being upright.

The next day’s outing, however, was for an easy twitch.  I only had to get out of the car and find some open space along the railing of the Arrowsic-Georgetown bridge over the Back River.

So yeah, the Steller’s Sea-Eagle is back, and it was in full (albeit fairly distant) view in our first visit with it of the year. I’ll get out of my recliner for a Steller’s Sea-Eagle any day!  It was also good to catch up with a friend and get out of the house for the second day in a row.

A few days later, Jeannette and I took a walk at Winslow Park in Freeport (2/9) where we were thrilled to find 7 Barrow’s Goldeneyes (3 drakes and 4 hens), the second highest count that I have had here in nearly a decade. They put on a great show, too.

A visit to the Auburn Riverwalk on the 13th yielded only one 1st-winter Iceland Gull, while a walk along Brown’s Point Road in Bowdoinham the next day produced a couple of pioneering Northern Flickers.

So there ya have it…my last month of birdwatching. With slow progress on my recovery, I expect feeder-watching will dominate my activity for a few more weeks, but temperature swings will make that interesting…and hopefully another snowstorm or two. I need to be out and about with few limitations by the time spring is here to stay!

Why There are so Many Warblers at Feeders in Maine Right Now (5/3/19).

IMG_4182-edited-edited
On another damp and dreary morning at Florida Lake Park in Freeport on Thursday, I encountered 25-30 Yellow-rumped Warblers and 15 or so Palm Warblers. That was my best total of the season there so far, but in the last week of April through first week of May, I often see tallies of each into the triple digits.

On Friday it was drier, but still cool and raw at Morgan Meadow WMA. I finally hit 5 species of warblers on a morning with my first-of-year (finally) Black-and-white Warbler.  About 20-25 Yellow-rumped and about 15 Palm Warblers were present. For perspective, on 5/3 last year, I hit 10 species of warblers at Florida Lake.

These are two of my favorite mid-spring migration patches, and in most years, I am at Florida Lake Park nearly every day. But this “spring”, it has been lackluster at best; worthless at worst. There just aren’t many birds around.

But it is definitely the spring for warblers at feeders!  After our Facebook post on Wednesday garnered lots of attention and feedback, I thought I would expand a little, as clearly this is a very unusual – perhaps even unprecedented – event.

While Pine Warblers are regular at feeders, especially in early spring – and quite a few of us see some Yellow-rumped Warblers at feeders every year – we cannot recall a spring in which so many people are reporting so many of each at feeders throughout southern Maine.  In fact, many folks are reporting Yellow-rumped Warblers at their feeders for the “first time ever.”  Even more unusual, we’ve had reports of Palm Warblers at feeders, too – something that is almost never seen.

Pine Warbler is our only regular, wide-spread “feeder warbler” in most seasons

At home in Pownal, we’re up to 20 Yellow-rumped (and our usual pair of Pines), with as many as 8 Yellow-rumps frequenting the feeders at the store this week. We see them annually on our feeders at home, especially on damp and cold mornings, but this year the flock has been slowly but steadily building and has been consistently present for almost 3 weeks. In both locales, a diversity of food is being consumed by this normally-insectivorous (at least in spring and summer) species. In rough order of popularity, they are eating: live mealworms, dried mealworms, insect suet, Nutsie and Mr. Bird nut blocks (especially the Bugs, Nuts,&Fruit block), peanut splits, Birdberry jelly, and even some seed. While a little hulled sunflower isn’t surprising, at home, we even have them gobbling up white proso millet from our tray feeder!

In fact, until Thursday, I’ve had more Yellow-rumps at our feeders than on any morning at Florida Lake Park! And this is instructive.

Midges are not yet emerging from the pond there, and even through some Red Maples are finally blooming, insect activity has been minimal or even non-existent at this important early-flowering tree. The phenology (to put it simply, the timing of things in nature over the course of the year) is off –way off – this spring. Food resources are not keeping up with the calendar.
Red_Maple

The jet stream is stuck to our south, resulting in unseasonable cool and very unsettled weather, with a steady progression of storm systems and disturbances crossing our area. This pattern is impeding the progress of our spring, and of migrants arriving from the south (I have yet to even see a Black-and-white Warbler this year, for example!). But the cool and wet weather is resulting in natural food sources being well behind schedule, so the birds that are here – on time in many cases – are searching for alternative food sources. And therefore: warblers at feeders.
Jet stream, 4-30-19

This diagram of the jet stream from 4/30 shows the tight gradient and zonal flow that has been dominating our weather pattern and is preventing the arrival of warm temperatures and “spring.”

Or, as better explained by the National Weather Service office in Gray:

April_weather

Meanwhile, cherries, apples, crabapples, Serviceberry, and other important early-season flowering trees aren’t even close to blooming. Nectar, pollen, and even the petals and new buds are consumed, but more importantly for most of our migrants, those flowers attract insects that are then eaten by birds. The forecast is for some better conditions for migration in the coming days, and that will start to deliver us newly returning migrants, but those birds will also have fewer food sources than normal.

In seasons like this, the supplemental food from well-stocked feeding stations becomes more important than usual. Ruby-throated Hummingbirds are already being reported; what would those birds do without a nectar feeder (no red dye!!!!) right now? And of course, who knows what kind of condition all of these hungry Yellow-rumped Warblers would be in right now without feeders.
IMG_5941_edited-2

Soon, other migrants such as orioles, tanagers, catbirds, and a wide array of warblers (or Neotropical migrants) will be arriving, and they need food after their long journeys. Especially until spring catches up (those long-distance migrants have no idea how delayed our season is up here), feeders will continue to be important for migrants – and unexpectedly productive birding hotspots.
IMG_9042-edited-2-edited

There are a lot of hungry birds out there right now, and without a doubt, many of us will get to enjoy species we don’t usually get to see, or at least no so closely. So put your jacket on, come by the store for some high-quality foodstuffs (our insect suet is flying off the shelves right now!) and keep that feeding station well-stocked.  Our migrants thank you.

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.
