Grasshopper Sparrow visits Krzyzewskiville

After watching Duke handle Winston-Salem State last night in an exhibition basketball game I was walking through Krzyzewskiville to meet my dad at the Sheffield Tennis Center when I noticed a small bird fluttering against a ground-level window.  I easily caught it by hand and brought it into the light...
Grasshopper Sparrow
...a Grasshopper Sparrow ?!?

I got my brother to snap a few iPhone photos and then let it go...
Grasshopper Sparrow
The bird was clearly trying to migrate. Perhaps it struck a window and then got against the northwest face of the building.

This was my first ever Grasshopper Sparrow on migration and an exceptionally late one at that.  There are only 3 prior eBird records of the species in North Carolina for the month of November.

Grasshopper Sparrow

Since birds are known to be portentous (Homer et al., ca. 700 BC), I'll go ahead and declare this to be a good omen for the Duke tennis teams this coming season.

American Bittern in SWAMP





 Last week I was out in the Duke University SWAMP helping lead a field trip for the Wetlands Ecology and Management class.  I had just explained to the students how we are keeping track of bird sightings in the SWAMP using ebird when not a minute later we stumbled upon a new bird to add to our site list...
American Bittern
 ...to my surprise an American Bittern was prowling around in the aquatic vegetation not 30 feet in front of the bird blind!

It's pretty rare to see one of these away from the coast. 

 And usually they do a better job staying hidden!

The bird seemed pretty unconcerned about curious birders and strolled out into the open to hunt crayfish.

 After gobbling a few small ones, it caught a huge bright red one that looked like a lobster
Blood red legs...
But it proved to be too much for this bird to handle and the bittern had to throw this one back...
a whopper!


 As of posting, this bird has been around for 8 days. It seems to be finding plenty of food and has already weathered some assaults from the resident Great Blue Heron. I wonder if it will stick around through the winter?

Top 10 birds of 2011


Yes, this is coming out 6 months late.  And it is on a much lower plane compared to my top ten from 2010 (it’s what I get for visiting Europe instead of the Neotropics).  But better late than never!

In 2011 I saw 405 bird species, of which 92 were lifers (way down from 907 with 649 lifers in 2010).  About two-thirds of these lifers I found on a couple trips to Europe, with 48 coming while exploring Greece and Croatia and 15 more from a later trip to Prague to attend a Society of Wetland Scientists conference. 

Making a top-10 list is a highly subjective (not to mention silly!) exercise.  Last year every bird I listed was a life bird from the tropics and listed by the IUCN as a species of concern. Also most were endemic and thus could only be found in a relatively small geographic area.  

This time around I didn’t see nearly enough endangered, impossible-to-find birds, so I’m mixing in some somewhat mundane birds that were significant because of where I found them.  But I’m only considering including birds that I found (or co-found); chases don’t count.  So the Allen’s Hummingbird in Catawba Co., NC and the Franklin’s Gull at Jordan Lake, for example, won’t make this list despite being fantastic birds for North Carolina.  Other people (Dwayne Martin and Thierry Besancon) did the hard work of finding and identifying these out-of-range rarities.  

Otherwise I’m making selections based on rarity, difficulty to find and/or identify, and to a lesser extent on charisma/looks.

In keeping with last year, we’ll make this a challenge.  I’m sure many folks have seen many of these birds, but has anybody seen them all?  Send me your total out of ten and whoever has the most will win a prize: an original Brown Boobies t-shirt in the size of your choice (S M L XL). 

On to the list!

* * *

10. Olive-sided Flycatcher

Olive-sided Flycatcher - Pocosin Lakes NWR

This is a declining species that is a pretty rare migrant through North Carolina.  It is especially rare in the coastal plain where there have only been a dozen or so records.  I found mine on August 11 in Pocosin Lakes National Wildlife Refuge.  

Nice tuxedo jacket! A rare sight in coastal NC
*bonus point if you have seen one in the coastal plain of NC*

9. Eurasian Bee-eater

Eating bees! (I think)

Also not particularly rare, but perhaps the most colorful European bird (a relatively unimpressive accomplishment in a continent that has nearly cornered the market on Little Brown Jobs).  I saw hundreds of these (quite a spectacle!) migrating through the Greek Isles while I was Island hopping my way from Rhodes over to my brother’s wedding on Paros. 

Lot's of Bee-Eaters!

8. Greenish Warbler

Greenish Warbler and its genus–phyloscopus—are prime example of the uninspiring plumage and identification challenges that the European birder faces.  It wouldn’t even matter if I had a decent photo of it…it would still be a drab bird and there still would be lingering identification doubts.  Luckily it was singing in the Red Bog I visited on a field trip as part of my conference in the Czech Republic. This wetland we visited has relict boreal vegetation from the Pleistocene and may be one of the southernmost refuges for this high-latitude species.  

7. Anhinga
Anhinga - Durham, NC

Tom Krakauer and I found this bird at a housing development pond in Northern Durham County, which was the first record of the species for the Durham Christmas Bird Count. 

It was a mild enough winter I guess

These are trash birds in Florida, but very rare in Durham...especially so in winter. 
Anhingas in Florida are hard to miss
*bonus point if you've seen an Anhing in Durham*

6. Citrine Wagtail
Citrine Wagtail (female) in Rhodes, Greece - rare this far west

I found a female in a creek bed in Rhodes Greece in May.  It was flagged as "rare" by ebird's filters and apparently it does not frequently stray this far west on its migration.  Unfortunately it was not the colorful male, but I was lucky that it was keeping company with a couple Yellow Wagtails, which made it much easier to identify. 

*bonus point if you've seen a Citrine Wagtail west of Asia*

5. Eleonora’s Falcon
Eleonora's Falcon - light morph

This is a really cool raptor with a relatively small breeding range that covers some Mediterranean Islands.  I saw dozens on the Greek Island of Tilos, which is thought to support 10% of the world's population.  It comes in two color morphs.

Eleonora's Falcon - dark morph

4. Short-toed Eagle

I'm not sure how rare a bird this is, but a woman from the Hellenic Ornithological Society on Tilos told me that it had not been previously recorded on the island.  So it was completely unprecedented  here at least!

Short-toed Eagle - a first for Tilos, Greece

I wrote up a formal description and sent them links to my video, but never heard anything back from any ornithologists or bird records people. 

*bonus point if you've seen Short-toed Eagle on Tilos*

3. Long-billed Dowitcher

Long-billed Dowitcher - Falls Lake, NC

I saw a lot of rare shorebirds on Falls Lake at the end of last summer, but this is the only one that I "discovered."  I was surprised later when I couldn't find any previous records for Durham, so as far as I can tell, this bird was a Durham County first. 

A first for Durham (?)

Perhaps others have had 'dowitcher sp.' at Falls Lake that were suspected of being Long-billed that were never confirmed.  Mine was kind enough to vocalize so there wasn't any doubt.

*bonus point if you've seen Long-billed Dowitcher in Durham*

2. Audouin’s Gull

Audouin's Gull is the only bird on this list that is currently experiencing any sort of extinction risk according to the IUCN which declares it to be 'near-threatened.'  In the 1960s it was one of the rarest gulls on Earth with only some 1,000 remaining.  Now the population is some 10 times the level of its low point, and stable thanks, no doubt, to some diligent effort by conservationists.  Despite the recovery, Audouin's Gull is still a rare bird that is pretty strictly pelagic, so tough to see.  I saw mine from a ferry near Nissyros, Greece.

1. Yellow Rail

I actually went on two successful Yellow Rail trips in 2011. Both were in Carteret County in sections of North River Marsh, one was in January and the other in December. This is one of the most difficult to see of all breeding North American bird species. Our (now infamous) method for finding them is documented here and here.

* * *

So leave your score in the comments below (the bonus points are to break a tie) and take your shot at the prize!  

Hopefully somebody can top Derb Carter (last year's reigning champ).  I haven't gotten him his t-shirt yet, but I'm sure he doesn't need two!

locally grown Yellow-crowned Night-Herons

Over the weekend I investigated the suspicious rumors of Yellow-crowned Night-Herons nesting in marshes around Durham and Chapel Hill.  What could these birds possibly be doing around the triangle, when they should be down at the beach?  Eating crayfish and raising young?  Likely story!

And by "rumors" I just mean great photos of nests taken by top local birders...clearly this was a mystery in need of investigation!

Luckily I was able to convince Will Cook to let me cover the highway 54 waterfowl impoundments for the Chapel Hill Spring Bird count.  I had never birded these spots before (until recently I thought they were duck prisons and I'm not into captive birds), so I wasn't sure what to expect.

But when I arrived at dawn, lo and behold the trees were filled with Yellow-crowned Night-Herons!
Yellow-crowned Night-Herons at the New Hope Creek waterfowl impoundment
Well, actually I only counted 7, but it was still a heck of a lot more Night-Heron action than I expected to find!

When I passed back by their haunt at 9 am, there wasn't a single one left to be found.  They had all gone off to roost for the day I assume.  They are Night-Herons after all, so-called because of their nocturnal (or maybe crepuscular?) behavior.


Look at those toes! How can that be comfortable?



I'm not sure whether the local population is growing or it's just that birders aren't at these little artificial highway-side marshes at dawn very often (I suspect both).  All I know is that there is a ton of habitat similar to the area I covered that is either inaccessible or virtually never checked.

A simple extrapolation leads me to believe that at least several dozen Yellow-crowned Night-Herons must breed in the area.  Yet until 5 or 6 years ago these birds were almost never detected on area spring bird counts.  The previous record high count for the Chapel Hill Spring Count was 11 individuals.  If only I could have been at two impoundments at once perhaps I could have broken the record...

Oh well, maybe next year!

Spring Sprang Sprung


It has been a whirlwind the past few weeks with birding, term papers and field work…and now I find myself finally updating this blog with the first week of May gone.  Most of the exciting spring migrants have already passed over the rapidly warming central piedmont in favor of higher latitudes and elevations. 

Blackpoll Warbler

I saw this Blackpoll Warbler out my window the other day; a harbinger of the beginning of the end of spring migration.

According to the old-timers at the Carolina Club’s 75th Anniversary meeting in Raleigh this past weekend, the rain storms just didn’t come at the right time to cause the fallout that every birder prays for in spring.  As a result many of the uncommon transient warblers were downright rare.  Nevertheless through two full days of leading area field trips for CBC participants I was able to turn up 21 warbler species.  Not bad at all!

Of course this says more about the sites I was assigned than anything else.  

On my Saturday morning trip to the ever popular birding hotspot, Mason Farm, we stumbled upon one migrant flock that had a Magnolia and Cape May Warbler—both gorgeous males!  And the entry marsh had a about a dozen sandpipers: mostly Solitary with a few Least and a Spotted. 

In the afternoon I took a smaller group to Eno River State Park where we got Rose-breasted Grosbeaks, Scarlet Tanagers and lots of Black-throated Blue Warblers.  But the coolest sighting might have been the Red-shouldered Hawk that flew by with a snake in its bill.

On Friday I led a group to Howell Woods down in Johnston County, which is thick with bottomland swamp species such as Hooded Warbler, Kentucky Warbler and Acadian Flycatcher. 

Acadian Flycatcher
It even has the elusive Swainson’s Warbler, which cooperatively sat up and sang for the group giving nearly everyone fantastic looks and me a passable photo of lifer #1553!

Swainson's Warbler!
Legendary naturalist Scott Weidensaul was in our group and even he was thrilled by this bird.  Or at least he said as much before electrifying the club and visitors with a talk about the wonders of bird migration.  Both Scott’s presentation and the venue, the recently completed North Carolina Museum of Natural Sciences, left me awestruck.  It was a fantastic way to cap the meeting.

Last weekend I covered Quail Roost with Tom Krakauer for the Durham spring bird count again and we crushed our total from last year by about 10 species.  We had Natalia Ocampo-Penuela partially to thank for this; she came along to get a few life birds and ended up spotting one of the better birds of the count: a gorgeous male Blackburnian Warbler!  But the best bird for me was a flock of about 120 Bobolinks we found in a field of alfalfa. 
Bobolinks! Durham bird #204

Since the count was in late April, it was the first chance to see many of the returning breeding birds singing away on territory, such as this Blue Grosbeak…

…or this Yellow-breasted Chat.

We also saw a nice male Orchard Oriole.

There’s still time for some late-moving migrants, but once June rolls around and the summer heat really fires up I recommend visiting the beach or the coast...and to bring a bathing suit as well as binoculars!

Deja vu? Western Tanager! (again)

When I heard from Ali that there was a Western Tanager visiting a feeder in Durham, I couldn't resist going to see it.
Western Tanager in Durham!
This one was a female, so not quite as pretty as the one down in Pinehurst from last month, but it is the first one documented in Durham County.  Pretty Cool!
motion blur

These birds don't linger on the feeder and shooting through a window on a low-light cloudy morning makes it tough to get a crisp photo.
Cloaca!
See you later!

I wonder when it might migrate west?

A big thanks to Della Zimmerman and her mother for hosting!

A big year for Durham?


After the crazy streak of rare shorebirds on upper Falls Lake this fall I realized I had a pretty decent Durham County list going for the year.  And with Nate Swick of the Drinking Bird doing his Triangle Big Year, John Vanderpoel on the brink of setting an ABA record, and with that awesome, star-studded, money-losing movie coming out, I figured why not jump on this band wagon?

Merry Christmas Bird Count!



I joined Tom Krakauer and Ken (whose last name I can’t recall) in Quail Roost up in northern Durham County to help with the Durham Christmas Bird Count.  I already commented on the beauty of this part of Durham in my post about the spring count here.

A xenophilic day in Durham

I started off by going to the Eno River to chase the Great "White" Heron that had been reported.
White morph Great Blue Heron

Sure enough.  This thing was no Egret!

y(Y?)ellow-bellied flycatcher

There have been quite a few recent local reports of Yellow-bellied Flycatcher, a rather rare migrant to North Carolina.  It seems that this is either a great fall to see the species or a great fall to see another of the confusing Empidonax flycatchers, such as a first-year Acadian with yellow-washed belly, and report it as a Yellow-bellied.  

Without hearing birds of this genus vocalize, identification can be quite tricky, and many a cautious birder will stick with Empidonax sp. Even under ideal viewing conditions.  

Take this bird I photographed at Brickhouse Road over the weekend…
 Not a great look, but definitely some sort of empid.  

Moments later I came upon another empid. that may or may not have been the same individual.  This one clearly had a yellow belly, green back and even a yellowish-looking throat. 

I followed it for several salleys along the path and it spent time along the forest edge on both the more mature side as well as the denser, younger wet side.
After a while it took a break from foraging and settled cooperatively for a few minutes in this tree.
What's it doing eating a caterpillar?  I thought these things were supposed to catch flies!
So this post has turned into an ID quiz for which I have no answer key.  Can anybody tell me what this bird is?

Previously I had never seen an immature Acadian nor a Yellow-bellied Flycatcher.  Surely this bird is one or the other… but which?  

If the photos aren’t enough… Check out this video… 

No it doesn't vocalize or do anything super-exciting.  It just looks around, and more importantly stays in focus  (I have several other clips in which my camera decided that a twig was far more interesting.)

I'll admit I'm not flycatcher expert, but I'm starting to lean toward Sierran Elaenia =P

Update 10/14/11:

After consulting carolinabirds and frontiers in bird identification listservs there was no consensus among expert opinion.  I think I got a total of 5 votes for Yellow-bellied and 4 votes for Acadian.  In general folks in the Acadian camp were more confident in their ID.

Jeff Pippen's advice was probably best: go get Ken Kaufman's book and figure it out yourself.  


The section on empids is really helpful for determining which attributes are most useful (i.e. bill size/shape, primary projection) and which are not (i.e. color, tail flicking).  

The main problem with the pictures I posted is that they show more of the less-useful indicators.  I captured the bill from several different angles, but it's size seems to change from one photo to the next.  

The result was a crazy juxtaposition of comments, such as...

Expert A: "...the smaller bill...seems to point towards Yellow-bellied."
Expert B: "The bill is clearly broader at the base, longer, and pointier than Yellow-bellied, Least, or Willow/Alder Flycatchers."

So I went back to my original photos and videos and found that some of my "bad" pictures actually illustrate the important field marks better than the "good" photos above. 

In these photos (of the same individual) the bird here is in direct sunlight and the color is washed out...



...BUT the primary projection is shown much more clearly

...AND it is easier to see the width of the base of the bill.  

The apparently broad bill seems to fit much better with Acadian than Yellow-bellied. 

The primary projection also looks to be long...perhaps not too long to rule out Yellow-bellied on its own, but I think it also favors Acadian.  

So after chasing my tail all over the place and being pulled apart by conflicting opinions, I'm right about where I started with my best guess for the ID.  

Big thanks to everybody who has commented and emailed me about this bird...especially to those who voted for Yellow-bellied Flycatcher!  Unfortunately I don't think I can, in good faith, mark it down as such (especially since it would be a life tick).  

I've certainly learned a lot and hope others have as well.  Also, further comment and discussion is more than welcome.

More Falls Lake absurdity

Since classes resumed up birding opportunities have been woefully few and far between for me. The coincidence of the fall semester and fall migration, I suspect, is frustrating for many an academic birder.

So many odd birds have appeared at nearby Falls Lake in the past month it seems that every weekend it just has to be my birding destination.

There was the dark morph Parasitic Jaeger that Jeff Pippen found a couple weekends ago… perhaps the fourth record of the species in the North Carolina Piedmont. It was almost surely a relic from the recent passage of Hurricane Irene.

Here is my awful phone-scoped photo from about a mile away at Hickory Hills boat ramp. The white lump on the right is a Ring-billed Gull and the dark lump on the left is the jaeger.
Parasitic Jaeger with Ring-billed Gull (use your imagination)
Since the species relies on pilfering fish from other seabirds and there were just a few Caspian Terns around to compliment the lone gull as potential targets, I suspect this poor bird was exhausted and starved.  And likely doomed.

Then there was the American Oystercatcher that Steve Shultz stumbled upon. I didn’t bother to try phone-scoping this one, but it is apparently only the third record for the North Carolina piedmont.
American Oystercatcher
This picture is actually from Carteret County; I just figured I should include an Oystercatcher photo.  

All these trips to Falls Lake have kept me out of the woods hunting for warblers and other migrant passerines, which have been moving through in decent numbers over the past week. This is a bit of a tragedy since some really great birds have been turning up in the triangle, such as Yellow-bellied Flycatcher, Wilson’s Warbler and Philadelphia Vireo, to name a few.

A silver lining to missing out on warblers was a large swallow flock at Ellerbe Creek that yielded my first Bank Swallow for North Carolina (#276).


Another was the gorgeous pair of American Avocets that has been be hanging around pools near the mouth of Ellerbe Creek.
American Avocet with prey
I had seen avocets before at Pea Island National Wildlife Refuge at the coast, but never this close and never doing their characteristic sweep feeding!
Check out the video!


Oh and I had promised a photo of a confusing fall warbler.  Check out this one I saw at Ellerbe Creek. 
Confusing fall warbler!
What warbler shows a white eye ring, yellow lores, bold white wing bars and a bright yellow chest?

None of the warblers in my Sibley do.  A creative combination of different plumages of Pine Warbler could fit the description, but Pines don't generally hang out in low willow trees with Common Yellowthroats.  There also were no pine trees in the vicinity. 

Anyone have a suggestion?

What a silly ending to a post about not seeing warblers.  Even when I see them it's not like I can identify them anyway! =P
