The science behind a bird fallout…there’s an app for that!!!

Birding the Sioux Falls area in April and the first half of May was…sloooooooooooooowwwww. With the late cold weather and snow, and continued wet spring precipitation, there was certainly plenty of water around (and there still is). But shorebirds were very slow all spring near Sioux Falls (perhaps just spread out?). Sparrow migration was utterly spectacular in April, but other songbirds? Once the sparrows left, it seemed like there weren’t any other songbirds filling the void. Certainly not warblers, which were few and far between for much of May. With the South Dakota Ornithologist’s Union (SDOU) meeting in Brandon on May 17-19, and with an incredibly wet forecast, the prognosis for good birding wasn’t great.

And then a funny thing happened…songbird migration ended up being utterly spectacular that weekend. The birds seemed to have arrived overnight, with warblers galore, and plenty of other songbirds as well. I personally had a 20-warbler day that Saturday (the 18th), and that’s with me whiffing on a few species that others saw in the area. It was one of the best, if not the best, warbler and songbird days I’ve had here in the 20 years I’ve been birding.

So what happened? As a scientist, I say LET’S CHECK THE SCIENCE behind it! You know how they say “There’s an app for that?” Well there’s also typically a scientific explanation behind…everything, if you look hard enough. That’s certainly true in this case.

For one, let’s check the weather radar for the overnight period from Friday, May 17th through Saturday May 18th. The weather that Friday was cloudy and rainy, driven by a low pressure system and a slowly moving front moving northeastward out of Nebraska. With the system predicted to generally stall over our area for the weekend, the forecast was bleak.

May 17th, 2019 - Weather Map
Weather map on 6:00AM (CST) on Friday, May 17th, showing a stalled to slowly moving stationary front just to our south. The forecast was for the low pressure system in Colorado to slowly move northeastward, bring showers and thunderstorms to the region for Friday night and into the weekend.

The weather system did move northeasterly through the afternoon and evening, triggering storms both along the trailing warm front to the south through Nebraska and Kansas, as well as more unsettled weather wrapping around the low pressure system. Moderate to strong northeasterly winds were found behind the low pressure system, but in front of the low were southerly and southeasterly winds…including in the area around Sioux Falls. It took until daybreak for the low pressure system to reach the Sioux Falls area, basically sitting directly over the region. But from the previous evening through daybreak on May 18th, an area from Sioux Falls, southward into extreme eastern Nebraska and all of Iowa and Minnesota were subject to south and southeasterly winds.

Surface weather map at 6:00 AM CST, showing the low sitting almost directly over Sioux Falls. But all night long, the counter-clockwise winds around the low funneled southerly and southeasterly winds through an area from far eastern South Dakota, and eastward into Iowa and Minnesota.

Given how slow the migration had been all spring long, the birds had to be…somewhere. But where? How could science have explained the fallout of warblers and other birds that weekend? The weather map and the southeasterly winds provide one clue, but the other is provided by weather radar itself. Since the 1950s, it’s been understood that weather radar could potentially identify features in the sky other than the weather…and that includes birds. There’s even a term for it now…Radar Aeroecology. A 1956 paper by Bonham and Blake discussed the radar echoes provided by both birds and flying insects. While research continued in the decades since, it’s only recently that the information has been made available for a birder’s benefit.

The animated map below shows national-scale radar returns for the night of May 17th. The advancing low and front, and associated precipitation, can be seen as it moves out of Colorado, through Nebraska and into South Dakota. But what of the radar returns in the eastern half of the country? Those are birds…birds taking flight just after sunset to resume their spring migration northward. You can identify the “bloom” around each radar location shortly after sunset, with the blooms appearing east to west as the sun sets. Where are the heaviest migration “blooms”? Look at the radars lighting up after sunset in the Midwest…St. Louis…Des Moines…other radars in Missouri, Illinois, and Iowa depicting heavy densities of birds taking flight.

Radar loop from approximately 6:00 PM (CST) Friday, May 17th, 2019 through 6:00 AM Saturday, May 18th, 2019. The areas south and east of Sioux Falls show a clear, very strong signal representing heavy migration of birds taking flight that evening.

But how can we translate those radar echos to where the birds are moving? In recent years, Cornell University, in partnership with multiple academic institutions, have developed “BirdCast“. They have developed algorithms that use weather radar returns to quantify the density of birds, while using short-term weather forecasts to project likely movements. The resultant “BirdCast” provides a 1- to 3-day look on likely bird migration hotspots.

The animated map below provides a depiction of estimated bird migration traffic that night. Ahead of the advancing front, southerly and southeasterly winds were favorable for migration, particularly as large densities of birds were already stacked up from the previous days and weeks. Sioux Falls was on the western edge of this migration hotspot, a beneficiary of favorable weather patterns bringing in birds from Missouri, Iowa, and Minnesota.

Birdcast depiction of migration traffic rate (bird density) and directional movements, from about 6:00 pm Friday, May 17th, through 6:00 AM Saturday, May 18th. with northerly winds and lower bird densities in the western Great Plains, very little bird movement is noted. However, ahead of the advancing front, extremely high migration densities are noted from Missouri, Illinois, and Iowa radar sites, with southeasterly winds pushing them northwestward…towards Sioux Falls. The solid lines represent the advancing sunset (red) and sunrise (yellow).

The map below depicts the situation that occurred throughout much of the first half of May. Prevailing weather patterns and storms, along with the cool weather, kept birds stacked up to our south and east, with a very slow spring migration to this point in South Dakota. The week prior to the big Sioux Falls fallout, birds were so far south that the Houston area birders declared a “Lights Out” period from May 9th-12th to avoid confusing the mass of migrating birds. But they had a long ways to go to get to South Dakota.

Houston Audubon "Lights Out" for May 9-12
Image from the Houston Audubon site, calling for a “lights out” period from May 9th to 12th. Heavy migrations were predicted the week before the Sioux Falls fallout…but FAR to our south and east.

The result of the changing weather pattern…an absolutely spectacular weekend of birding in the Sioux Falls area the weekend of May 17-19, particularly as the forecast deluge mostly fizzled out. I admit that even I as a scientist was somewhat skeptical of the Cornell BirdCasts. But after the events of that weekend, count me as a firm believer!

Here are some photos of the spectacular birds of that weekend:

Unusual cold weather has birds struggling in South Dakota

Five very different birds, but five species with something very much in common. The cool, wet spring continues, with rain and wind in the eastern part of South Dakota, and a late May snowstorm in the western part of the state. It had already been an odd migration given the cool temps that don’t want to give way to spring. Until last Friday (May 17th, songbird migration was noticeably slow, with very few warblers around other than Yellow-rumped. But that seemed to have changed last weekend. On Saturday (May 18th) we had a major fall-out of migrants, with warblers of every kind (I had 20 species on Saturday), vireos, flycatchers, and other songbirds appearing seemingly out of thin air. The birding this weekend was positively SPECTACULAR, and there’s no doubt for me it was the best warbler spotting in the 20 years I’ve been birding.

That spectacular birding has come with a price, however. With cool and wet conditions continuing, you can tell birds are struggling. The problem? I just think there aren’t the usual insects out yet for this time of year. Because of that, you’re seeing species with behaviors you normally don’t see. From a bird photography perspective I guess it’s been great, as the birds have been 1) concentrated, with many birds often foraging in select locations out of the wind and rain, and in areas where a few insects might be, and 2) many species have been down lower to the ground than normal.

Here’s a pictorial of five species I’ve encountered in recent days, five species that all appear to be impacted by the cool wet weather.

In the account of the Great Crested Flycatcher on my main webpage, for “behavior” it states that Great Crested Flycatchers are “usually found high in the tree canopy, more often heard than seen”. Normally that’s true. They’re a quite vocal species, and I do hear them more than I actually see them. However, in the last week, I’ve seen a number of them, down low, foraging in areas that seem rather odd for the species. At both Newton Hills State Park and Good Earth State Park, I’ve seen multiple Great-crested Flycatchers foraging on the ground or in low grasslands. Again, my take is that insects are hard to find in the cool wet weather, leading birds like Great Crested Flycatchers to forage in areas they normally would not. Photo is from May 19th at Good Earth State Park.
While birding Newton Hills State Park Sunday, I saw three Scarlet Tanagers, all foraging within a few feet of each other. Seeing Scarlet Tanagers at Newton Hills isn’t news, as it’s one of the best places in the state to find them. To see three foraging together is unusual, however. Seeing all three ON THE GROUND, foraging as if they were Robins, is definitely unusual. It was a cornucopia of color, with a Red-headed Woodpecker low in the nearby sumac, an Indigo bunting down low, and American Robins and Scarlet Tanagers feeding together as if they were the same species. I’ve seen more Scarlet Tanagers this spring than I remember seeing before, but frankly it’s because they’re using habitats and behaviors they normally would not. Photo is from May 19th at Newton Hills State Park.
On Sunday, I spent quite a bit of time at Lake Lakota, a reservoir right next to Newton Hills State Park. Sunday morning was a nasty day…temps in the 30s, foggy, and cloudy with occasional drizzle. Again, from a photographer’s perspective it certainly played to my advantage, as birds were heavily concentrated along the lake shores of Lake Lakota. That’s been a common theme in the last week, with insect eating birds often found very near water sources. Given their behavior and concentration, presumably it’s because these insect-eating birds are going where the food is, and with the cold weather, it seems insects associated with water bodies are some of the few that are around. There have been a few times over the last 20 years where on a cold May day, I’ve found heavy concentrations of all kinds of swallow species on the ground, and Sunday was one of those days. Sitting on the beach at Lake Lakota were Tree Swallows, Barn Swallows, Cliff Swallows, Northern Rough-winged Swallows, and Bank Swallows. At any one time, it appeared that about two-thirds of the birds were perched on the beach, with a few low in nearby shrubs and trees. The other third were swooping over the lake itself, extremely close to the water’s surface as they searched for food. Those on the beach would occasionally move, but not in typical swallow fashion. Several appeared to sometimes be almost walking around looking for food, VERY strange for species that collect their insect prey in flight. It wasn’t just swallows, as other species were also concentrated on the beach, including more Baltimore Orioles and Orchard Orioles than I’ve ever seen in one location before. Given that they were seemingly struggling, I didn’t want to get too close for photos, so the photo above is of a Tree Swallow from a similar situation several years ago, on a very cold morning at Lake Thompson in South Dakota.
Speaking of shorelines along water bodies…while most warbler species were pretty much absent in the area until Saturday, that definitely wasn’t the case with Yellow-rumped Warblers. They have been THICK, but often in areas you don’t associate with warblers. While driving north of Wall Lake in western Minnehaha County last week, I saw many birds perched along a barbed wire fence, occasionally flying out to “flycatch”, capturing insects in mid-air. It was an area with a couple of shallow wetlands, areas that must have hatched some mosquitos or other flying insects despite the cool wet weather. It was an area with nary a tree in sight, yet as I got closer I saw what they were…ALL Yellow-rumped Warblers, in big numbers, hanging out here in a completely open landscape and making do with what bugs they could find. The situation was similar one day when I was looking for shorebirds at Weisensee Slough in western Minnehaha County. Weisensee is the last place I’d think of going to look for warblers, given as it’s a very large wetland/water body, with just no woodland patches on the accessible part along the road. That was a very windy day, shorebirds were almost completely absent (another blog post about shorebird migration perhaps), and with the chop on the water, it was difficult to see many birds out on the lake. Yet as I approached the ONE location along the road with a few very small willow trees, I saw a heavy concentration of Yellow-rumped Warblers, perched on the shoreline itself or low in the trees on the lee side of the wind, trying to capture insects. The photo above is one of those Yellow-rumped Warblers from Weisensee.
On Facebook I’ve been seeing many photos people have posted of their orange and jelly feeders, with big concentrations of Orioles. On the east side of the state, that means Baltimore and Orchard Orioles, while Bullock’s Orioles are also thrown into the mix in western South Dakota. that’s certainly been the case at my feeders as well, as I typically have to fill my two jelly cups every morning. The same thing happened during a cold snap last May, where very hungry, insect-starved Orioles showed up at my feeders in force…also the first time Orchard Orioles joined the Baltimore Orioles in our suburban neighborhood.

The invisible bird in plain sight – Common Nighthawk

When I bird, I nearly always am by myself. Birding is my zen time, my time to forget about all the worries of the day. It’s my time to get away from cell phones, other electronics, and yeah…I admit it…people. The last two weeks notwithstanding (I’ve done a LOT of birding during that time), normally I don’t get out all that often, and its a way for me to decompress and have some time alone. My behavior when birding also is most conducive to birding alone. For example, when I saw a very large group of Black Terns dipping and diving over Grass Lake the other night, I did what I OFTEN do…I stayed an entire hour with them. Part of it is the photography side of my hobby. Patience is the greatest attribute you can have in bird photography, and shooting a bird that flies in an erratic pattern certainly taxes that patience. But rather than trying for a few minutes, getting frustrated, and leaving…I kept at it, watching their patterns as they’d circle around for another pass along the shoreline, noting that the strong wind often put them in a near hover mode, and eventually getting quite a few nice photos.

However, I do realize there are advantages to birding in a group that I generally miss out on. This weekend the South Dakota Ornithologist’s Union (SDOU) held their spring meeting in Brandon. On Saturday I ran into SDOU birders twice at Perry Nature Area near Sioux Falls, and joined them for a couple of hours that afternoon. Given the incredible warbler migration on Saturday, I knew I wanted to try Newton Hills State Park Sunday morning, and after birding for an hour or so, I ran into another SDOU group of birders. As I got out and greeting them, a young, very enthusiastic (and very good!) birder in the group (Peter) immediately pointed upward to the branch of a nearby tree…Common Nighthawk! Just sitting there on a horizontal branch, apparently not giving a damn about all the birders just 10 yards away.

There’s no way in hell I would have seen that bird if I’d have been birding alone. Even the group of SDOU birders said they were moving around that spot for quite some time before someone noticed it.

I greatly enjoyed the weekend, both my time birding alone, and my time with the SDOU crowd. The tradeoffs between both styles of birding…when birding alone, I ran into more Black-billed Cuckoos than I ever had in one spot, and was able to spend quite a bit of time with them and get some good photos. I didn’t get any really good photos while birding with the crowd, but I definitely saw more birds! When you have 6-8 pairs of binoculars trained on different spots, it DEFINITELY is helpful during spring migration, when little warblers, vireos, flycatchers, and other birds are often flitting about in the treetops.

Over the years, my birding style has definitely changed. I’ve been birding for 20 years now, and I’d say that for the first 15 years, I was laser-focused on the photography side of things. It seems nuts for me to say this now, but…I didn’t even OWN a pair of binoculars until 5 years ago!! All those little warblers flitting about in the tree tops? They didn’t interest me, as I knew there was no way in hell I’d ever get a photo of them! But I’ve evolved from a photographer who birds, into a birder who also takes photographs. Over the last few years, some of my favorite birding memories don’t involve the camera, but times where I’ve just sat in one spot and watched some rare or interesting bird, often for an hour or more.

My very unusual (for me!) time spent actually (GASP!) birding with other people this weekend was nice…perhaps it’s just another step as I transition from a “photography first” to “birding first” mentality.

A cuckoo kind of a day

I’ve got so many potential things to focus on from an incredible weekend of birding. The 20-species warbler day yesterday, plenty of other goodies, has my head spinning in terms of what to focus for a blog post.

One of the more curious sightings from today at Newton Hills State Park came while patrolling the beach area. It was a bit foggy yet, drizzle was falling, and it was pretty damned cold for May 19th, and there were birds galore near the beach at Lake Lakota, all foraging on the ground or close to it, in search of whatever few insects might be out. While watching all the commotion, a bird with a noticeably long tail flew past and landed in the bushes behind me. Cuckoo!! But which one? I switched my focus from the beach to the bushes by the parking, and there! A Black-billed Cuckoo! I lucked into 3 Yellow-billed Cuckoos at Newton Hills last spring, but it’s been a few years since I’ve even seen a Black-billed Cuckoo.

As I sat and tried to get a good look at cuckoo #1 through the foliage, here came another long-tailed bird…another Black-billed Cuckoo! I ended up spending half an hour near that bush, and during that time there were up to FOUR Black-billed Cuckoos frolicking about, doing some half-hearted chasing of each other, but mostly looking like they were just trying to survive until the weather warmed up and there was more for them to eat.

Another great morning despite the weather. Here are some of the Cuckoo photos, all from the one location.

Ho-hum South Dakota birding — a 20-warbler day!

Bay-breasted Warbler - Setophaga castanea

With all the birding I’ve done over the last 2 weeks, I have to say…migration had been disappointing to this point. I love my sparrows, and sparrow migration was very good, but the other two groups of migrants that I love…shorebirds and warblers…have been painfully slow in arriving. In the case of shorebirds, I don’t think any sort of migratory breakthrough is going to happen this spring. It could be they’re just spread out, given how incredibly wet it’s been and how much standing water there is over much of the upper Great Plains. But at this stage, I’m not counting on a big influx of shorebirds.

Warblers have been very similar. If you like Yellow-rumped, this has been your spring! They have been absolutely thick, particularly last week when they were not only in woodland and forest edges, but many were hanging out on shorelines, fencelines, or other seemingly uncharacteristic locations. But other than Yellow-rumped Warblers? To say “not much” would be a disservice to the term “not much”, as for most species, they’ve been non-existent.

That changed today. HOLY…COW…did that change today!! I’ve been birding 20 years now. That’s 20 spring migrations where I’ve put in a LOT of effort, hoping to find migratory warblers and other songbirds. In those 20 years, I must say that today was THE best warbler day I have ever had, hands down. It wasn’t just numbers, although numbers were quite good. It was the jaw-dropping variety of warbler species that are moving through the area right now. They weren’t necessarily “dripping off the trees”…a favorite term for some folks when there’s a warbler “fall-out”. But they were certainly around in very good numbers, and at times it seemed that every bird you looked at was a different species.

There were some that were quite abundant. Tennessee and Yellow-rumped Warblers were common, although Tennessee were scattered everywhere, while most of the Yellow-rumped I saw were along the Big Sioux River at Good Earth State Park. Given how intense the birding was and how often I tried to keep my focus on the treetops, I have no doubt my count below is low for those two species, and I KNOW it’s quite low for Yellow Warbler, as they are also extremely abundant right now. When I saw one of those “common” species, I often didn’t pause to enter into eBird. And why was that?

Because there were SO many “good” warbler species, including species I haven’t seen in years. I haven’t seen Blackburnian Warblers very often in South Dakota, and I have zero photos of the species. In fact, there are only two occasions where I even remember seeing a Blackburnian Warbler. Today? FOUR gorgeous Blackburnians, with 2 at Perry Nature Area, and 2 at Good Earth State Park. It’s been 14 years since I’ve seen a Bay-breasted Warbler, but I found one at Good Earth. Mourning Warbler? I have ZERO photos of the species and don’t see them all that often, but I found a pair in close proximity this afternoon. Chestnut-sided are a species I probably see every other year or so, and always one at at time. Today? I saw six, with five spotted from one location at Good Earth!! Magnolia numbered 9 on the day, Blackpoll were at 4, while most of the others were single sightings.

20 species of warbler in one day! 19 of those were from two locations (Perry Nature Area and Good Earth State Park), while 1 was from Ditch Road just north of Sioux Falls (Northern Waterthrush). Here’s the list of warblers on a birding day I will always remember:

  1. Ovenbird – 3 (2 singing and not seen, one seen and not heard)
  2. Golden-winged Warbler – Seen and heard twice, in two visits to Perry Nature Area today (same bird I’m sure…count of 1)
  3. Tennessee Warbler – 47 — I have no doubt this is a big undercount, as many times I didn’t stop to enter them in eBird
  4. Orange-crowned Warbler – 4
  5. Nashville Warbler – 1
  6. Mourning Warbler – 2 – And now I do have photos of the species! Crappy photos, but I had none before today!
  7. Common Yellowthroat – 7 – If I’d taken the time to properly account for all those singing along the Big Sioux River in the northern end of Good Earth State Park, this number would be a lot higher
  8. American Redstart – 9 –
  9. Magnolia – 9 – Definitely the most I’ve seen in one day
  10. Bay-breasted Warbler – A REAL treat as I haven’t seen one in over a decade
  11. Blackburnian Warbler – 4 – TWICE the number I’ve seen in my other 20 springs of birding in South Dakota
  12. Yellow Warbler – 16 – That’s what I had taken the time to enter in eBird. But particularly if I would have paid close attention and recorded every time I heard a Yellow Warbler, the number would be double or triple this.
  13. Chestnut-sided Warbler – 6 – All at Good Earth State park, with an astounding 5 observed while standing near one giant burr oak
  14. Blackpoll Warbler – 4
  15. Yellow-rumped Warbler – 25 – As they’ve been all spring, nearly all were near water, with them flycatching along the banks of the Big Sioux River in Good Earth State Park
  16. Black-throated Green Warbler – 1 – One of my faves, good to see one
  17. Canada Warbler – 1 – I’ll need to check my records but I don’t see these often at all.
  18. Northern Waterthrush – 1 – The only one not at Good Earth or Perry Nature Area, found while doing a short check of Ditch Road north of Sioux Falls.
  19. Black-and-White Warbler – 1 – Usually one of the most common migrants, and I have seen plenty this spring, but only one today.
  20. Wilson’s Warbler – 1 – Also one I typically see every year, but it’s been pretty slow for them this year.
Magnolia Warbler - Setophaga magnolia
I would kill for more warbler photos like this. Magnolia Warblers though sometimes do forage quite low in the canopy, or along a woodland edge, and thus I do have more photos of them than I do most warblers. Unfortunately, it’s SO hard to get photos like this of many warblers, as birds like Blackburnian, Black-throated Green, and many others seem to always stay quite high in the canopy.

Ruddy Turnstones – Madison Waterfowl Production Area

Another night, another rarity for South Dakota! Last night it was a White-eyed Vireo from Newton Hills State Park. Tonight I went looking for shorebirds up around Madison. It was actually pretty slow for shorebirds, except for one spot…the west side of the Madison Waterfowl Production Area, just southeast of Madison. The highlight…22 Ruddy Turnstones! If I do see them in South Dakota, which isn’t very often, it’s almost always one or two birds, so seeing 22 in one spot was a treat.

A couple of quick photos from tonight. After doing some really hardcore birding over the last week…I’m beat! Just want bed, no more photo processing!

A lifer! White-eyed Vireo

White-eyed Vireo -Vireo griseus

About a week and a half ago, I was birding in Newton Hills State Park, along Sergeant Creek. It’s a well-known area for birding, and seems to be a bit of a migrant trap, with a number of unusual (for South Dakota) birds seen there. As I was walking up the trail along the creek, I heard a bird singing in a clump of flowering bushes. The song was…a mess…all over the place, variable, with some harsh notes thrown in. For a second I thought it was a weird Gray Catbird song, but it didn’t seem right. I stopped and paused, and it wasn’t long before I found the culprit…White-eyed Vireo!! A lifer!!

White-eyed Vireos are normally found as summer breeding birds in the Southeastern United States, making it as far north as Pennsylvania and Massachusetts in the Northeast, and as far west as the southeastern quarter of Iowa. The map at the bottom shows eBird sightings for White-eyed Vireo in South Dakota. There’s not many! EBird has two sightings in the Sioux Falls Area…one that was banded up in Aberdeen…one seen in the Black Hills…one at Union Grove State Park…and now this bird at Newton Hills. I also seem to remember Bridget J. seeing one at Newton Hills last spring (?) but I don’t see it in eBird. This past weekend, a group of Sioux Falls birders also found the bird, in the same location where it was seen the week before.

The problem though with my first sighting…I couldn’t get a photo! He was a vocal little sucker, singing his heart out and flitting through the foliage, but I never got any good photo chances. Tonight I went back, not really looking for the White-eyed Vireo but walking the same trail. I was only about 10 yards further down the trail than last time when I heard the same unique song. He was still there! This time I was determined to get a photo. He was still foraging in the same general area, actively moving through the bushes and nearby trees, flying out a few times to flycatch. But like last time, he would always land back in the foliage. It took a while, but I was finally able to find a little opening in the twigs and foliage to get a few shots of him while he paused for a moment.

After 20 years of birding, it’s getting harder and harder to get a lifer in South Dakota…it’s always great when you find one! I hope this one beats the odds, sticks around, and somehow finds a mate to join him on his lil’ South Dakota vacation.

Bonanza of Bitterns

It’s been a weird spring. As it was last year, it’s been cool and wet, and migration has been slow or delayed. Two groups of birds I live for in spring are shorebirds and warblers, but migration has been incredibly slow for both, with few warblers other than the ubiquitous Yellow-rumped showing up, and very few shorebirds other than yellowlegs. Other songbirds have also been slow to arrive, as even the ever present Eastern Kingbird has been extremely scarce to date.

However, like last year, one bird has been making itself quite visible…American Bittern. It’s odd, because I went several years without seeing an American Bittern, and now in the past two years, I’ve seen many. I went birding this weekend west of Sioux Falls, and in the span of one mile, came across three American Bitterns, including one doing the classic unk-a-lunk-a song while his buddy watched from nearby.

Warm weather finally arrives today, with a high near 76. Hopefully with the warm weather warblers and other migrants arrive as well, but I’m thankful that the bitterns have taken up a little bit of the slack this spring! A few photos of the bitterns from the weekend:

American Bittern - Botaurus lentiginosus
American Bittern May 11th, 2019 Near Grass Lake, Minnehaha County, South Dakota. This one was EXTREMELY close to the road and allowed as good of looks at an American Bittern as I’ve ever had.
American Bittern - Botaurus lentiginosus
American Bittern May 11th, 2019 Near Grass Lake, Minnehaha County, South Dakota. A lot further out than the first, and not in nearly as good a hiding spot! Bitterns usually can be hard to spot, but this guy didn’t get the message on how Bitterns are supposed to act. I think the fact that he isn’t even bothering to stretch his neck out and act like brown cattails shows that he knew he blew it. 🙂
American Bittern - Botaurus lentiginosus
An instant favorite and the cover shot of my main website page, this American Bittern had a buddy! I watched this one for about 5 minutes while the Yellow-headed Blackbird flitted around the general area where he was “hiding”, hoping to get a shot like this with both birds.

Solved! One of life’s 3 big mysteries

Orange-crowned Warbler - Vermivora celata

When I woke this morning, I had no idea that by the end of the day, I would have solved one of life’s three biggest mysteries. These are questions of profound importance that have bedeviled mankind ever since we pulled ourselves out of the muck, learned to walk upright, and started pointing binoculars at birds. Of course I’m talking about the “Big 3”:

  1. Does a Ring-necked Duck have a ringed neck?
  2. Where’s the red on a Red-bellied Woodpecker’s belly? and,
  3. What color crown does an Orange-crowned Warbler have?
Yellow-rumped Warbler - Setophaga coronata
Yellow-rumped Warblers and Orange-crowned Warblers seem to be best buds in migration, often hanging out together. One big difference between the two…Yellow-rumped Warblers are PROPERLY NAMED, with an obvious yellow rump.

Now, Orange-crowned Warblers are one of the most common migrant warblers we have in the state, just behind the Yellow-rumped Warbler. But you know what my friends? YELLOW-RUMPED WARBLERS ACTUALLY HAVE, like, you know…YELLOW RUMPS!!! So where does that leave us with Orange-crowned Warblers?

I always thought the naming of Orange-crowned Warblers was kind of a cosmic joke. Someone saw a rather plain bird with a touch of color but really no contrasting features whatsoever, and said…HEY! Let’s have some fun with this! Instead of something like “Drab Olive Warbler”, let’s call it an Orange-crowned Warbler!

After seeing a number of Orange-crowned Warblers, tonight I’d had enough. When one started flitting around the crabapple tree right outside my sunroom window, I decided to get down to the bottom of it all. Now, my wife knows I talk to birds. Hell, I do it all the time, particularly when I really get excited! You can be DAMNED sure that when I saw that Whooping Crane a week and a half ago that we had one of the longer, more fulfilling conversations I’ve ever had in life. Usually I just say whatever pops into my head, with deep, thoughtful conversational elements such as “hey sweetie!!”? Or “You’re a pretty bird!” When a bird is extremely cooperative and has allowed a number of good photos, it’s not unusual for me to toss out a “Thank you sweetie” as I depart. (If you’re wondering…sadly for me…every word of this is true).

Now, I admit those conversations are usually very one sided, so today when I started talking to the Orange-crowned Warbler in my crabapple, I wasn’t expecting the bird to engage. However, much to my surprise, when I softly muttered “now where’s that supposed orange crown of yours?”, the bird paused, gave me a thoughtful stare, and then proceeded to dip his head and hold a pose for several seconds, as if to say “Hey, dumbass…I’ve got your orange crown right here”.

And that, as they say, is that! A few clicks of the camera shutter, some evidence of orange feathering on the crown, and one of life’s greatest mysteries is solved.

Whooping Crane Video

Ah-HA!! Just when you thought I was over myself seeing a Whooping Crane last Friday, more imagery emerges! But this time it’s video. I…RARELY…ever take video. I don’t know why. Perhaps it’s the fact that I never really walk around with a tripod. It’s one thing to shoot a still with a long lens while hand-holding, as you can get sharp individual frames. It’s another to hand-hold a long lens and try to take anything close to stable video. This is watching the Whooping Crane in Buffalo County, South Dakota, while using a fence post as a temporary tripod. Just 26 seconds of video, but shows perhaps a bit more of the behavior of this guy. He was pretty relaxed the whole time I watched him (about 2 hours), and didn’t care about the guy with the camera or all the passing cars on the highway.
