As you get older you start to wonder about things like…why the hell do I have thousands upon thousands of digital photos on my computer? What’s the purpose? What’s going to happen to them when I’m gone? I certainly have an online presence in social media and my website where my photos are shown, but I wanted to start making something more tangible that perhaps my son and others could have, something more than just photos on a hard drive.
My wife always makes photobooks from our “big” yearly vacation, as well as one for family photos for a given year. Why not do the same with all the thousands of photos I have sitting around on my computer? I started to make photobooks based on themes (categories of birds). So far I’ve only gotten one back from the printer, but I really liked it so have followed up and made five more that are currently being printed. This morning I just finished #6.
I’m keeping them pretty simple, with what to me is an elegant black hard cover and background on the interior pages, with photos and a short descriptions of the species, date, and location the photo was taken. Simple, because I wanted the books to focus on the photos themselves, and not any descriptive material from me.
The six I’ve completed are:
Here are some example pages from some of the books. I’ve got a least another 8 or 10 planned. It will take me a while to get them all done, but will be a nice series to have and hold for the future.
There are some species I instantly think of as being iconic northern Great Plains species when I hear the name. Marbled Godwit. Baird’s Sparrow. Lark Bunting. Greater Prairie Chicken. When I think of driving west and north from my home in far southeastern South Dakota, and heading to the central or western part of the state, away from the mosaic of corn and soybeans that dominates my area, I think of wide open grasslands, few people, and a unique ecosystem of iconic bird species. In my mind that also includes the Chestnut-collared Longspur, a gorgeous bird with a unique dark plumage (breeding plumage males) that I almost see when I heard the name, hanging out on a barbed wire fence with nothing but grassland for miles around.
Yesterday I was processing bird photos (still a few years behind) and working on my website. I was working on a directory of photos I got last July in Hyde County, in the east-central part of the state, and got to one photo, and one photo only, of a Chestnut-collared Longspur. It’s not a great photo, and in fact, if it were another species where I had an abundance of photos, I might have thrown it out. I was shooting photos of shorebirds at a small wetland I’d stumbled across, when the lone longspur flew into my vision and plopped down to grab a quick drink. It was mid-day, the lighting was poor, but I grabbed a quick shot, surprised I’d seen one here, as I usually think of them as being a bird I’d find further to the east and north.
Then, as what tends to happen, I downloaded all the photos from that day, and they sat there unprocessed. I’d forgotten about that photo and encounter until processing photos yesterday, and knowing my collection of Chestnut-collared Longspur photos was sparse, I decided to keep the photo and work on the associated species pages on my website. As I was doing so, it brought to light just how rare an encounter the sighting was for me.
Two. TWO. That’s how many “decent” photos of the species I’ve managed to grab in South Dakota in the 21 years I’ve been birding. Despite my internal impression of the species as an iconic Northern Prairie species, both my actual sightings and photographs of the species have been extremely limited.
As I started working on my dedicated species page for the Chestnut-collared Longspur, I got to the “Conservation Status” section of the page and started doing some research, beefing up my current (very sparse) content. When I first created the page for the species some 20 years ago, there seemingly weren’t any worries about the status of the species. But when I looked at the IUCN (International Union for Conservation of Nature) web page on the conservation status of the species, it was immediately clear it was a species in trouble. The species has been downgraded in status twice in recent years as numbers have started to dwindle.
It’s wasn’t a cheery exercise reading more about the status of the species. The Breeding Bird Survey (BBS) data, the gold standard for rigorous, systematic tracking of population trends over time, indicated a startling decline in the species of almost 90% from 1966 (Sauer et al. 2016). Other data sources show equally shocking declines, with estimates of >95% species loss in the Canadian portion of the Chestnut-collared Longspur range in less than 40 years, from 1971 to 2017 (COSEWIC 2019). A species that was once a common breeding bird in Nebraska, Kansas, and Minnesota has nearly been extirpated from those states, and previously robust populations elsewhere in its historical range are now gone. Clearly, it’s a species in serious trouble.
So what’s the cause of the trouble? Most sources agree that habitat loss is the primary factor in their decline. The Northern Great Plains used to be a mosaic of natural grasslands, wetlands, and riparian corridors with woodlands. Davis (2004) studied habitat needs for the Chestnut-collared Longspur and found that they required quite large, contiguous blocks of grassland to successfully breed. They avoided even what might be considered “prime” grassland habitat if the size of that grassland patch were anything less than 100 acres. With vast swaths of former Great Plains grassland converted to agricultural land uses in the last 150 years, grassland communities have been devastated, and remaining grassland patches have been heavily fragmented. In short, Chestnut-collared Longspurs can’t find enough suitable large patches of grassland on which to breed.
That downward spiral of suitable habitat continues currently, and in fact has recently intensified in parts of the Great Plains. That includes right here in South Dakota, where demand for corn and soybeans, including the uptick in demand due to biofuel use, has resulted in massive swaths of grassland and prairie land being plowed under for the first time in just the last 15-20 years. South Dakota itself is a hotspot of this habitat loss, particularly eastern and north-central South Dakota, where the rate of grassland habitat loss in recent years is actually higher than that of the well-publicized loss of tropical forest in parts of South America.
It’s not just agriculture that’s driving habitat loss in the northern Great Plains. Energy development is front and center in parts of that range, as new methods for extracting fossil fuels have been developed in the last 20 years. The image below depicts the “nighttime lights” dataset for a portion of the northern US. These data record visible light energy from the Earth’s surface at night. Larger cities are clearly visible in the data, but…what’s the massive blob of light in sparsely populated western North Dakota?
North Dakota is now the 2nd largest oil producing state in the country, thanks to fracking technology developed in the 2000s that has allowed companies to extract a difficult to access, but massive resource of oil in the region. There are hundreds upon hundreds of oil wells in the region, wells that may be spaced out across the massive prairie landscape, but…each well requires access, each well requires energy sources. None of this was there even just 15 years ago, but now the network of wells, roads, and powerlines has severely fragmented grassland habitat in the region.
As the map above shows, the Bakken formation is smack dab in the middle of the breeding range for the Chestnut-collared Longspur. The area in North Dakota was developed SO incredibly rapidly, with economic considerations overwhelming any thought for habitat or environmental considerations. But for a species such as the Chestnut-collared Longspur that’s been declining precipitously and needs large, intact grassland patches to breed, oil and gas activity in the Bakken couldn’t have come at a worse time, or in a worse place.
Two. Perhaps it’s not a surprise I only have to photos of Chestnut-collared Longspurs, a species that’s “vulnerable” and fading fast. Get out there and enjoy this species while you can, as your chances of seeing it in the future may be fading.
One of my New Year’s Resolution…less time sulking about the state of the world, more time being productive. Now when I say “productive”, I don’t necessarily mean work! No, I’m thinking more about my free time, and instead of wasting it, spending it doing things I love. Of course that includes birding, but it also includes working on my massive, out of control website, which I’ve neglected lately.
One element of my website are “Hotspots” pages, detailed information on specific birding hotspots in South Dakota. It’s been a work in progress, as it takes quite a long time to make each one of the hotspot pages! Over the last week I have completed a new one, one that was LONG overdue…for Good Earth State Park just outside of Sioux Falls.
We live across the street from the Big Sioux Recreation Area, a state park of comparable size, that also borders the Big Sioux River and has extensive, forested riparian habitat. While I do bird there, in recent years it just can’t hold a candle compared to Good Earth State Park. Much of it for me is how the parks are managed. The Big Sioux Recreation Area has a BIG focus on camping and other heavy recreational use. As a result, they’ve really disappointed me in recent years by ripping out a lot of good bird habitat to make way for camping, frisbee golf, etc. I get it…you have to manage the parks for multiple uses, but overall in South Dakota, birders and birding are the LAST priorities for park management.
That’s what’s so great about Good Earth. It’s not managed for birding, but there’s no camping. That alone makes a huge difference, as it’s less busy and there’s much more natural vegetation. The big draw of the park for me is the variety of habitats, from upland forest, to gorgeous, well-vegetated grasslands with plenty of native plants, to riparian floodplain. The trail system is incredible as well, with several miles of very well maintained trails.
I’ll save the rest for the new “Birding Hotspot” page itself! I hope you find this useful as you consider Good Earth State Park for your next birding trip. Click below to access the page:
As 2020 comes to a close, I had a great end to the year from a birding perspective yesterday! I made one last birding trip, heading up towards Brookings to try to find some Short-eared Owls that had been seen recently. I hadn’t seen any yet this year, and I thought it would be nice to add one more species to what’s been my best South Dakota “big year” yet. But not only did I find a Short-eared Owl, but the first owl I saw was a gorgeous immature female Snowy Owl! Two new 2020 species for the state, on December 30th, and with both being owl species, I couldn’t have asked for a better close to the year.
The two owls put me at 262 species seen in South Dakota in 2020…breaking my own personal high of 256 from last year. It was certainly a terrific year in many aspects, with not only a great variety of species, but some life species, both South Dakota lifers, and overall lifers! Highlights for the year:
We live in interesting times. “Interesting” often being downright disheartening, as we have a society in the US that seems to be embracing the future depicted in the movie Idiocracy. The same US that used to lead the world in innovation and science now has about 40% of the population who shows outright disdain, if not hatred, of “experts”, including science. I could go on…and on…and on…and on…on this topic. But I’ll turn that conversation to how science has benefits in so many aspects of life.
That includes birding! As someone who has been a birder and a bird photographer for 20+ years now, I realize that technical photography skills are a very small part of successful bird photography. The big challenge is getting close enough to a bird! That means knowing when, and where birds will be, and how that species normally behaves. Science can help with all three of these!
I had an absolutely, incredible, spectacular day birding today. It was a drippy, gloomy, dreary day, a day where normally I may not have even left the house. However…SCIENCE told me to leave the house!! Two days ago…Cornell University’s “Birdcast” predicted that the night of May 15th/16th would be a heavy migration night with birds arriving in eastern South Dakota in high numbers. I’ve learned to really trust the Birdcast predictions, particularly after a few events last year where the forecast immediately preceded some absolutely spectacular birding. So what did the forecast predict?
I headed out this morning before dawn, arriving at Newton Hills State Park in search of warblers and other migrating birds. Unfortunately, the rain arrived shortly after I did! It was extremely frustrating, as I could SEE many birds moving about in the forest canopy, but with the early hour, the clouds, and rain…it was difficult to see them well enough to identify them. I did bird for an hour or so, and did have a good time, identifying over 50 species. Normally a great time, but with the slight rain continuing and making photography difficult, I started to head home.
As I drove back home, the rain started to lighten, and eventually stopped. As I got within a couple of blocks from my house, I thought…SCIENCE! By god, that BirdCast hadn’t let me down in the past! I thought I’d try one more place while the rain held off, and ended up at Beaver Creek Nature Area, just 3-4 miles from our home. It’s a place where I’ve had decent luck before, but it’s never been as “hot” as Newton Hills.
That changed this morning! THANK YOU science, and thank you BirdCast! There’s one trail I normally take at Beaver Creek, which takes perhaps half an hour at most. Instead, I ended up walking around for nearly 2 1/2 hours. Almost one hour of that was sitting in one spot! There’s a ridge with a steep bank, where you can walk along canopy or mid-story of the trees growing in the ravine below. It’s been a place where I’ve had good luck before, but nothing like this! As I watched, wave after wave of birds were moving through the forest canopy, including…Warblers! The highlight of spring migration!
In 20 years of birding, I had yet to get a good photo of a Blackburnian Warbler. That ended today! I saw two here, both of whom were uncharacteristically cooperative for the camera. In total, in that 2+ hours, I saw 16 different Warbler species! A terrific day, and one that would have turned out very differently if I’d just looked out the window in the morning, had seen the rain and gloom, and stayed home.
One last trip to the Fort Pierre National Grasslands! It’s been a couple of weeks…just have had zero time to post photos…but I had a wonderful day trip to the Grasslands. After some rather slow years on the Grasslands, this was a good winter, although the birds were curiously concentrated on the eastern side, mostly in and around some very large prairie dog towns towards Highway 1806.
As always…Rough-legged Hawks predominated, but there were higher numbers of Ferruginous Hawks than I ever remember seeing in one day. Plenty of other “goodies” as well! With that, some photos from my trip a couple of weeks ago…
I never was really a “lister” as a birder until eBird came along. eBird makes it so ridiculously easy to track your sightings, and the tools they have to categorize your sightings by date…geography…comparison to other birders…certainly bring out the competitive side that many birders seem to have! However, even after I started using eBird, I never really set any yearly goals, such as a “big year”. The closest I ever came was a number of years ago when a birding friend at work and I had a very low-key competition to see who could see the most birds in South Dakota during the year.
I ended up at 212 that year, a very similar number to my friend. I’ve gotten close to that a few times since according to eBird, but never really had a “South Dakota Big Year” as a driving goal for my birding in a year. Going into this year though, my birding time had been declining and I seemed to be losing some interest. I thought setting a goal to break my yearly South Dakota record might re spark some of that enthusiasm.
It did!! I started early in January this year…a tough time to start building a bird list in South Dakota! Particularly in a very cold, snowy winter, getting up to just 100 birds by mid-April was doing very well! When spring migration rolled around, I spent more time birding than I have in years. As the year progressed, I never made it to spots like far northwestern South Dakota to tick off species like Baird’s Sparrow, but I made my usual trips to the central part of the state, the Missouri River dams, and a very rare (for me) dedicated birding trip to the Black Hills.
By mid-December, I’d easily passed my highest yearly total, with 248 species. With travel and family commitments in the latter half of the month, I wasn’t expecting to get any more, but when a White-winged Crossbill was seen in Sioux Falls the week before Christmas, I did make the short trip and checked of #249. One short of a nice round number!! I told my wife (notably NOT a birder, and not too invested in the number chase!) that the only way I’d get to 250 is if something unexpected showed up in the yard. Well, on Christmas Day I got a nice surprise present, when a Sharp-shinned Hawk nailed a House Sparrow in mid-flight in the back yard, and then proceeded to consume it right outside our sunroom window. Not that rare of a species around here in winter, but when entering the sighting into eBird, I was surprised that I hadn’t recorded that species yet in 2019, and it was indeed #250!
250 species for the year…a nice number to end with! Not as nice a number as the rather miraculous 303 found by Kenny Miller this year (WOW…considering we’ve only had about 420 species total that have ever been seen in the state), but it was enough for me to end up tied for 6th in the state this year. Something I never thought I’d do as a birder…comparing my year in such a manner…but again, that’s what the wonderful eBird tools do to even a pretty non-competitive birder!!
Sprinkled in those #250 are some definite highlights for the year…new life birds (7 new birds never sighted before anywhere), or new life birds for the state of South Dakota (an additional 9 new South Dakota lifers). Here are some of those 2019 highlights….including some from a major 2019 (and lifetime) birding highlight that’s definitely NOT South Dakota focused.
After being given a new role at work a month ago, I’ve been traveling and quite busy. I was determined to do something today I haven’t done in quite a while…take a whole day and just go birding. I wasn’t exactly optimistic when the day started. I wanted to see if raptors were starting to show up in the central part of the state, but thought it was probably a little too early.
I needn’t have worried! There were still a lot of Red-tailed Hawks around, probably more than the Rough-legged Hawks I saw. That’s one sign it’s still early in the winter raptor season, as pretty soon Rough-legged Hawks will greatly outnumber Red-tailed Hawks in that part of the state. It’s also early for any Gyrfalcon to be around on the grasslands, as it seems they typically don’t do so until most of the water freezes (I assume they hunt waterfowl around open water). But overall, I had great weather and a boatload of raptors today.
I did my “usual” route…starting out around the Presho and Kennebec area near dawn, working my way west, then heading up towards Pierre, including a stop on the Fort Pierre National Grasslands. For the day I ended up seeing at least 75 individual raptors, including ~10 Golden Eagles, ~10 Bald Eagles, ~25 Red-tailed Hawks, ~20 Rough-legged Hawks, plus 3 Ferruginous Hawks, 2 Prairie Falcons, several Northern Harriers, and even a Merlin.
Even better, I got a lifer below Oahe dam! A “photographic lifer”, a White-winged Scoter that was diving right next to shore and gobbling up crawfish. It’s a species I hadn’t seen before in South Dakota until about a week and a half ago, and today I was able to get some very close range photos.
A great day! And given how many raptors were around so early in the winter season, here’s hoping it’s an utterly spectacular winter for raptors in South Dakota. Some pics from the day:
I just haven’t had much time to take the new Canon 90D for a whirl, but went out to Good Earth State Park this morning at dawn. I LOVE birding this time of year, particularly for migrating sparrows. We get such an incredible variety that move through.
The star of the morning though was a rather lost Rock Wren. There aren’t any records of Rock Wren in eastern South Dakota in eBird, but a birder found one at Good Earth yesterday. Not really expecting to find him this morning, I was pleasantly surprised to see him sitting on a curb in the parking lot right as I got out of the car! He was an extremely tame little dude, at one point letting me sit about 6 feet away from him on the curb while we both warmed up in the morning sun.
Great morning, including for pics! And when shooting fall sparrows, it’s always wonderful to get some beautiful LeConte’s Sparrows in the mix.
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.
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.
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.
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.
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.
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:
