The Rarest of the Rare Winter Finches, Fletcher Community Park, NC, December 10, 2020

The Fall and Winter 2020 seasons have been punctuated by irruptions of many species of northern finches.  Even as far south as here in NC!  First there were Red Crossbills nesting in white pines at lower elevations away from the higher NC mountains where they are more typically seen.  More recently there have been occasional flyover Crossbills passing over areas even farther from the mountains – I’ve been lucky enough to have one each in Polk (3rd county record) and Rutherford Counties (2nd county record).  Then came large numbers of Pine Siskins and Purple Finches, along with Red-breasted Nuthatches, pouring through the area.  Next were Evening Grosbeaks that came come through in very small numbers.  Once again luck was on my side when a pair of Grosbeaks flew over as I was doing a “Big Sit” in my yard in November. 

And finally, there is the rarest of this winter’s finches – Common Redpoll.  Early in the Fall there was a considerable Redpoll irruption in the northeast, which expanded to a few sightings in the Mid-Atlantic.  Could this northernmost of the finches make it all the way to the Carolinas?  The answer is a resounding “Yes”.  The first sighting of a Redpoll in NC came on 11/13 in the north-central part of the state.  And then there was another sighting on 11/20 in the northern NC mountains.  Just 50 miles away as the winter finch flies. 

That’s definitely one to keep an eye out for.  Or perhaps more importantly to keep an ear out for.  Redpolls have pretty characteristic calls, although they are similar to some of the calls of Siskins.  For the next several weeks my nearly daily birding efforts really focused on trying to find Redpolls.  I especially birded weedy fields that might attract finch flocks.  And then I looked in stands of birch trees and wetter smooth alder thickets.  This year both are loaded with catkins, and some seeds, which are favorite foods for Redpolls.  All the while keeping my ears open for an isolated flyover bird.  Not too surprisingly I didn’t come up with a Redpoll, or even a Siskin for that matter as it appears that most of this irrupter have already passed through.

Then on 12/10 I took a trip to the Fletcher Community Park which is part of my territory on the Henderson County Christmas Count.  The park has a nice diverse set of habitats, including woodlands, shrubby edge, and adjacent agricultural fields.  Plus one of the more unique birding spots is a small pond in the middle of the park that often hosts a surprising array of waterfowl.  The pond is surrounded by a thick stand of birch trees with smooth alder as an understory, making it quite difficult to see the waterfowl.  I’ve found the only way to try to get an accurate count of the ducks is to walk slowly around the entire circumference of the pond peering through to the water wherever there are gaps in the vegetation. 

On the 10th I was about half-way around the pond picking out good numbers of Hooded Mergansers when I heard a distinct dry “chit chit chit” call low overhead – I had my Redpoll!  It sounded as if I flushed it from the birch trees or alder thickets and it flew off toward the west.  Unfortunately it was a heard-only bird, despite efforts to re-find it in the vegetation off to the west.  I wasn’t at the park just to look for Redpolls, but in hindsight, the vegetation around the pond is about as perfect as you can get for these wayward finches.  So maybe it should have been my key target after all. 

Common Redpoll was #309 for my NC statelist, and a first eBird record for Henderson County.  NC was my 15th state for this species – 12 it in its regular range (the blue-shaded states in my statebird map below), and the 3 brown states where it’s a rarity.  I still need it in quite a number of northern tier states where it’s regular, albeit typically only in irruption years (the cross-hatched states).

A Most Unexpected SC Rarity, Lake Conestee Nature Preserve, SC, November 19, 2020

My plan for November 19th was to start the day at Dobbins Farm in Anderson County, SC in search of a recently reported flock of Snow Geese.  Given that they were foraging around a small, easily visible farm pond, I expected I would very quickly either be able to check them off or know that they had moved on.  Then after a brief stay at the farm I would head across the GA/SC stateline to work on my GA list a bit.  At least that was the plan…

I arrived at Dobbins Farm at about 8 AM and instantly spotted the flock of Snow Geese on the lower pond.  Can’t get any easier than that.  (See my previous blog post for a summary of my recent Dobbins Farm sightings.)  I birded there another couple hours, and then headed west to cross into GA.  Key targets included several waterfowl, a number of sparrows, plus a few woodland birds like Red-breasted Nuthatch and Creeper.  In other words, I had opportunities in many different habitats.  My first stop was at the dam at Lake Hartwell where I had good numbers of waterfowl and gulls, but nothing out of the ordinary.  And a slow walk through the pine forest near the dam yielded a nice collection of landbirds but none of my targets. 

The next stop was a short distance away at the Elrod Ferry Recreation Area which is a wooded peninsula sticking out into Lake Hartwell.  Along the way I passed some blackberry thickets that looked good for sparrows – I decided I would double-back there after I birded the park.  The gate to the park was closed, so I parked at the entrance in a nice stand of pines.  Looked like a good spot for Nuthatches, and sure enough I soon heard a couple White-breasteds.  Then I spotted a Brown-headed.  And a few seconds later another Nuthatch popped into view – a Red-breasted.  Not only a new GA statebird, but that also gave me all 3 eastern Nuthatch species in just a couple minutes.  That was #234 for my GA list.  I just need this wide-ranging species in 3 more states to complete my statebird map below.


But wait – the title of this post mentioned an unexpected SC rarity, not GA.  I’m getting there…

I continued my walk in the park hoping to run into a Creeper, or maybe find some additional waterfowl species.  I was staring through the scope trying to turn a Horned Grebe into something better when my phone rang – it was Michael Robertson.  Michael recounted a bird he saw that morning while doing a regular census of an inaccessible portion of Lake Conestee Nature Preserve in Greenville, SC.  He described it as Mockingbird sized and shaped, but without the white wing patches.  Plus the bird was streaked below.  A most unlikely Bahama Mockingbird came to mind.  He said he would send me pictures to help with the ID.  While I waited for the pictures to arrive I thought about trying to re-find the mystery Grebe, and then continue to walk down the peninsula to hope for a Creeper.  But it sounded like Michael’s bird could be a really rare one, likely one that I’d want to chase after.  Plus Lake Conestee was almost directly on my route back home from GA.  So I decided to forgo additional GA possibilities, head back to my car, and start the drive toward Lake Conestee just in case.  As I drove out of the park I passed by those blackberry thickets and possible sparrow habitat – oh well, that would have to wait for a future trip.

I was well on my way toward Lake Conestee when the photos arrived.  I opened the first attachment and instantly knew Michael had found an exceptionally rare Sage Thrasher – likely a first for SC.  I called him to pass along the ID.  I was less than 30 minutes away and asked if it would be possible for me to look for this bird given that normally access is limited to his team when they do their regular censuses.  He said he might be able to get me access to the site, but it would be necessary for me to team up with one of the Conestee employees to escort me to the area where the bird was seen.  So the key hurdle was to find someone to be my escort.  I continued my drive toward the park with fingers crossed, and was just 15 minutes away when Michael called back reporting that one of the park naturalists would meet me and take me to the spot.  The stars were aligning!

I arrived at the park just a couple minutes before the naturalist, and soon we were taking the short walk to the site where Michael had the Sage Thrasher earlier.  But it was now late afternoon, several hours after he had found the bird.  Would it still be around?  The naturalist took us right to the spot of the earlier sighting.  We got a brief view of a Song Sparrow, and then a larger bird popped into view – we had the Sage Thrasher!  It was most cooperative, sitting out in the open long enough to get this phonescoped shot.


 Here is the site it was frequenting – not quite like its normal sagebrush habitat out west. 

SC was the second eastern state where I’ve seen Sage Thrasher as a rarity (the brown states in my statebird map below).  I’ve seen it in 12 western states in its regular range (the blue states) but still need it in the 4 cross-hatched states where it is regular in at least a portion of each state.

I can’t thank Michael Robertson enough for getting me access to the site, and the park naturalist for escorting me.  And although I’m very happy to have seen the bird, #281 for my SC list, I feel bad that only 1 other birder was able to see the bird later that day.  Unfortunately, the bird was not re-found the next day. 

Boy am I glad I cut my GA birding short and headed to Lake Conestee right away.  I may have passed up another statebird or 2 in GA, but will gladly trade them for a first state record in SC!

Three Rarities at Dobbins Farm, Anderson County, SC, November 2020

 

I was introduced to birding in Anderson County by my SC birding friends Michael Robertson and Gary Harbour back in November 2019.  The county has some excellent and diverse habitats including agricultural areas, woodlands, and lakes.  Some of the best birding in the ag lands is at Dobbins Farm, which features large pastures supporting a herd of cows, a feed lot, planted fields, and two large farm ponds.  The grassy fields are full of meadowlarks year-round, with occasional Brewer’s Blackbirds wintering especially near the cattle feeding troughs and feed lot.  The planted fields have Horned Larks year-round, joined by Pipit flocks in winter.  The ponds feature a surprising array of waterfowl and shorebirds.  And all these birds are kept on their toes by a nice collection of raptors that feed in the area.  The only downside is that access to these fine habitats is somewhat limited – there is just one road that passes through the farm, and although you are allowed to bird from the road, you can’t walk into the fields.

Here is a picture showing typical pasture habitat with one of the ponds in the background.


On that November 2019 trip we hoped (in fact expected) to see 2 long-staying Snow Geese at one of the ponds.  Alas, they were last seen the day before our trip.  Though Vesper and White-crowned Sparrows at nearby Prater Farm were nice additions to my SC list at the time. 

Then in November 2020 no less than 3 rarities were reported at Dobbins Farm.  Not all at once mind you, meaning that I had to make 3 separate trips to the site to chase after them.  Good thing it’s only about 90 minutes from home.  And there’s great birding at the spot even if the target rarities don’t cooperate.

November 13

On November 12, almost exactly a year after my initial trip to the area, came a report of a possible Western Meadowlark at Dobbins Farm.  When I saw a video of the singing bird there was little doubt that it was indeed a Western Meadowlark – both based on song and plumage.  It was most cooperative, not only given that it was in full song, but it was also visible quite close to the road.  Once accepted it would turn out to be only the 2nd SC record listed in eBird. 

But would it still be cooperative in the future?  After all, there were hundreds of acres of suitable habitat, with no access to areas not close to the roadway.  And with dozens of Eastern Meadowlarks singing and foraging in those fields, that meant that finding the target bird could be a needle-in-a-haystack kind of proposition, especially if it wasn’t singing.  But I decided to give it a try the next morning, hopeful that the bird would still be cooperative.

I arrived at 8 AM on Friday the 13th and there were already 8 or 9 birders on site.  One birder had heard the Western singing at about 7:30, but no one had had it since.  There were many Eastern Meadowlarks singing throughout the fields, along with good numbers of Larks and Pipits twittering from the planted fields.  Plus large flocks of Pine Siskins were feeding in the sunflower field.  Not to mention 10 or more Bald Eagles perched around the upper pond.  It was once again a great time at Dobbins Farm.  With the obvious exception that I wasn’t finding the target Western Meadowlark. 

I spent an hour or so waiting and listening around the area of the ponds with no success.  Then I noticed quite a bit of Meadowlark activity a short distance to the south as well, so I decided to take a walk down to that area.  I was by myself now so it would be a bit easier to pick out a Western song, especially if I had to separate it from the many Easterns singing in the area as well.  I listened for a while but with no luck.  Then I heard a different song not too far away.  I strained my ears and focused even more intently – and there was the song again.  It was the Western Meadowlark!  I was able to call over a couple other birders who also heard it.  And although we never saw the bird, we watched a Meadowlark fly from the general area where the song was coming from just as we stopped hearing it sing.  So perhaps we at least saw the bird in flight.  Seconds later the rest of the birders came down to that area but unfortunately we no longer heard the bird singing.  Though later that day some were able to see and hear the bird again in that general area. 

In my statebird map for Western Meadowlark below the blue-shaded states are those where I’ve seen this species in its regular range.  The cross-hatched states are those where I still need this species, generally along the eastern edge of its regular range.  And now I’ve seen it as a rarity in those 2 tan-shaded states – VT and of course SC.

November 19

And then on the 16th, while the Western Meadowlark was still being seen, came a report of a flock of Snow Geese at the lower pond.  I wouldn’t have thought that a flock of Snows would visit these little ponds, let alone hang out there for a while.  But of course I remembered those Snow Geese that stayed there in November 2019 for a week or more – moving on just before my trip there.  So maybe these birds would hang on for a while also.  But not wanting to tempt fate two Novembers in a row, I decided to head there as soon as I had the chance.  I met Gary Harbour there the morning of the 19th and the first thing we spotted was the flock of 9 Snow Geese on the lower pond – 5 white phase and 4 dark phase birds.  I got these passable phonescoped photos of the flock.



 Since they were so cooperative I had time to head across the stateline into GA for a bit of birding there.  As well as another stop back in SC.  But that’s for my next blog post. 

SC was my 43rd state for this wide-ranging Goose, including Maine where it’s a rarity.  And although it’s a rarity in the upstate of SC, it’s more expected in coastal SC so it’s not quite a rarity statewide.


November 24

All my earlier winter trips to Dobbins Farm and nearby spots have featured large numbers of Pipits and Horned Larks in the appropriate habitats.  That made me think that an occasional Lapland Longspur could be a possibility mixed in with those other “prairie birds”.  But with a bit of eBird research I found only a few records from the area, most recently in 2014 from Dobbins Farm and 2016 from Prater Farm.  It is a bit surprising that Lapland Longspur is such a rarity in the area, given that they are regular in the mid-South (AR, TN, MS), at even lower latitudes.  I remember seeing good-sized Longspur flocks in that area, including in AR where Lapland Longspur was my 10,000th total tick (sum of my state lists) back in December 2003.

Then on November 23 came a report on the Greenville County Bird Club listserve of a Lapland Longspur at Dobbins Farm.  The bird was seen in the planted fields, where the Larks and Pipits feed.  Plus another birder had a pair of Brewer’s Blackbirds there later in the day, out in the pasture with the cows.  Those were two key targets for me - it was time for yet another November trip to Dobbins Farm!

I arrived at Dobbins Farm at 8 AM the next morning, parking near the lower pond.  My plan was to listen intently for the unique rattling flight calls of a Longspur likely mixed in with Pipits or Larks, while scanning the pastures for blackbirds.  I started with a quick scan of the pasture, easily picking up the Snow Goose flock (I guess I didn’t need to make that last trip on the 19th after all).  Then I heard several blackbird call notes nearby.  It took me a while, but I eventually tracked down the calls and spotted a blackbird flying away from one of the feeding troughs.  I watched it in flight until it disappeared near the feed lot.  I couldn’t get enough on the bird to get an ID, but both the trough and the feedlot are excellent locations for a Brewer’s.  One that got away I’m afraid. 

Then I started my focus on the prairie birds.  I was hearing a few Horned Larks singing and calling, and an occasional Pipit, but had few birds in flight.  Over the next hour it was more of the same, though I did have a pair of birds fly overhead that gave a single call note that was different than the Larks and Pipits – reminiscent of a Longspur but not enough for me to figure out for sure.  A bit later a birder pulled up in a car and was asking what I was seeing.  While his car was running right next to me I spotted my first larger flock of Pipits overhead.  I desperately needed to listen to the call notes from this flock but couldn’t hear them over the engine noise.  This was getting frustrating…

It had now been about 90 minutes since I arrived and I still hadn’t come up with either of my targets.  Though I had had possibilities for both.  I was feeling pretty defeated, though I said to myself that just a few seconds of Longspur flight calls would turn it all around.  And just then I heard calls overhead and spotted a pair of birds flying from the planted fields.  The calls were dry rattles very different from the higher-pitched and more musical Lark and Pipit calls.  I had a pair of Longspurs!  They passed directly overhead and disappeared out in the pastures.  Then a couple minutes later I heard the calls again, and this time picked up 2 Longspurs flying low from the soybean field and landing far out in the sunflower field.  Although the birds were too far to ID visually, their call notes were unique, just like most other prairie birds.

SC was my 29th state for Lapland Longspur – still a lot of states to look for it in its regular range.  Though I now have it on my SC and WV lists as rarities.


 Quite a month for Dobbins Farm!
