A typical day on the Fort Pierre National Grasslands

Author: DakotaBirder • Discussion: 8 Comments
Fort Pierre National Grasslands - South Dakota

Two weeks off of work, winding down as I prepare to return to work tomorrow. It’s been a wonderful (and much needed!) break, with time with the family, and plenty of birding. In two weeks I managed to make it out to central South Dakota three times…more than I normally do all winter! It’s such a magical place for me in winter. Quiet…open…often harsh and unforgiving…yet very restorative for me when I need time alone to recharge.

So what’s the attraction? Central South Dakota? In the dead of winter? Here’s a photo synopsis of what it’s like, all photos from my most recent trip out there last Thursday/Friday.

Fort Pierre National Grasslands - Sunrise
Pre-dawn on the Fort Pierre National Grasslands. Normally I make a (long) day of it, leaving 3 hours before dawn so I can arrive just before the sun rises, and make the most out of short winter days (about 9 hours of sunlight at a minimum). This photo gives you a good idea of what it’s like as you await the sunrise…VAST…open…isolated…and other than barbed wire fences and a few powerlines, often not much of a sign of human habitation. An exciting time as the sun arises, as you just KNOW you’re about to have another wonderful day on the grasslands.
Pronghorn - Fort Pierre National Grasslands
It’s not ALL about birds! While winter raptors are my primary reason for coming to the region, there’s often other wildlife to catch your attention. On this trip I was thrilled to see a large herd of Pronghorn grazing on the rolling hills, just as the sun was rising. Mule Deer and White-tailed Deer are also often seen. Coyotes are certainly around, and I probably see them about every other trip to the Grasslands, but mostly at dawn. They’re extremely shy and difficult to approach.
Buteo Regalis - Ferruginous Hawk - Fort PIerre National Grasslands
There are a few private land holdings within the Grasslands boundaries, but there are more abandoned buildings than any other. In a land that’s often treeless or without any kind of high perches, these abandoned homesteads often are birding hotspots. Here a Ferruginous Hawk is perched next to an abandoned…Packard (?).
Gyrfalcon - Falco rusticolus
RAPTORS are the name of the game on the Fort Pierre National Grasslands, but there’s a definite hierarchy in terms of what I’d love to see!! The Holy Grail bird of the Fort Pierre National Grasslands…a Gyrfalcon! And not only a Gyrfalcon, but an adult Gyrfalcon. In the 20 years I’ve been birding the area, I’ve probably seen about 25 Gyrfalcons. I believe I can count on one hand how many of those have been adults, so I was thrilled to run across one on this trip. I watched from a long distance and took some photos from further away than I normally would, as I wanted to make sure I documented this bird’s presence. I’m glad I stopped so far away and grabbed some photos, because after watching it for perhaps 30 seconds, it flushed and flew away, and I never again found it on this trip.
Greater Prairie Chicken in Flight - Tympanuchus cupido
Why are there so many raptors on the Fort Pierre National Grasslands? Clearly raptors go where the food is. There undoubtedly must be a lot of voles and other small rodents, as that’s what I primarily see birds like Rough-legged Hawks catch. But another attractant to birds like the Gyrfalcon above are all the Ring-necked Pheasants, Sharp-tailed Grouse, and Greater Prairie Chickens that are around. It’s a popular hunting location for all of those species, and given that surrounding private lands often release birds (pheasants) for hunting, there’s never a shortage of any of those species. The native Sharp-tailed Grouse and Greater Prairie Chickens are VERY wary as a result of the hunting pressure, and I have few close photos of either species. On this trip I was very happy to get my first ever flight photo of a Greater Prairie Chicken. With the recent heavy snow, many of the game birds were struggling to find foraging grounds, and were concentrated along the roads more than usual.
Ring-necked Pheasant - Phasianus colchicus
Speaking of Pheasants…they are widespread in the area, but are probably less common on the Grasslands themselves than on the surrounding private lands.
Bald Eagle - Haliaeetus leucocephalus
You’ll see both Bald Eagles and Golden Eagles on the Grasslands. Golden Eagles are more often seen (they were downright common on the three recent trips I took), but even far from any open water, you will also often see Bald Eagles. I’m aware of at least 4 different nests just to the south of the Fort Pierre National Grasslands themselves, near the Presho area. This photo is along the Missouri River just to the north of the Grasslands, a stronghold of the species in the winter months.
Prairie Falcon - Falco mexicanus
A Prairie Falcon in flight. They’re definitely a larger bird than the American Kestrels you see a lot in the summer months (and to a much lesser extent, in winter). They’re larger than the Merlins you sometimes see on the Grasslands (including one I saw Friday). But they share the same “falcon” characteristic when they take flight, with much faster wingbeats than all the Buteo hawks in the region, and a more tapered wing. Couple the relatively large size and that classic falcon flight pattern, and Prairie Falcons OFTEN get my heart racing as I’m thinking that bird flying up in front of me may be a Gyrfalcon! On a typical day on the Grasslands though, I’m lucky if I see a Gyrfalcon, yet I almost always see 3 or 4 Prairie Falcons. Usually they’re pretty shy, but there’s been one hanging around County Line Road on the grasslands this winter that’s uncharacteristically curious. He’ll flush when you get anywhere close, as do nearly all Prairie Falcons. But then he has this habit of circling me one or two times before finding a different perch! It’s not often I can grab a Prairie Falcon in flight, so I’m pretty happy to have seen this guy on this past trip.
Rough-legged Hawk - Buteo lagopus
Always by FAR the most common raptor on the Fort Pierre National Grasslands in winter…a Rough-legged Hawk. I didn’t stop and record each one in eBird as I often do. But on a trip to the area the week before I saw nearly 50 of them, and I would suspect I tallied a similar number on this past trip. Gorgeous birds, and quite variable in plumage, although this is the typical plumage that you see.
Buteo jamaicensis - Red-tailed Hawk
The Fort Pierre National Grasslands are mostly treeless, and even during the summer months I’ve found Red-tailed Hawks are typically concentrated in the few wooded ravines, shelterbelts, or abandoned farmsteads in the area. In winter, those site tendencies are even more pronounced. Many Red-tailed Hawks move further south for the winter, and I find MANY more Red-tailed Hawks just south of the Grasslands (such as the Presho area) in winter than I do on the Grasslands themselves. However, over the 20+ years I’ve been birding the area, it’s quite obvious to me that more birds are overwintering in the region than used to. Similarly, 20 years ago it wasn’t common to find Western Meadowlark overwintering in any numbers, but on this past trip, there were a few spots where I stirred up a dozen or so Meadowlarks hanging out together. More Red-tailed Hawks, more Meadowlarks, fewer Gyrfalcons….that’s my impression of what’s happened over the last 20 years.
Golden Eagle - Aquila chrysaetos
The one photo here that’s not from last Thursday/Friday, as this was taken on the Grasslands 2 days before Christmas. My impression is that BOTH eagle species are getting much more common on the Grasslands. I have few if any photos of them 10 to 20 years ago, but now I typically see 6-10 each time I go out.

Do predator control programs help gamebirds like Pheasants? (Hint…No)

Author: DakotaBirder • Discussion: 2 Comments

Ring-necked Pheasant - Phasianus colchicus

South Dakota’s favorite bird…an introduced game bird that does have an economic impact in the state. but are predator control programs like Kristi Noem’s actually beneficial to pheasant populations? Or, in fact, is it likely to WORSEN the situation? For the scads of hunters and others who evidently have found my blog…read this post. Don’t take my word for it regarding this misguided predator control program. Take the word of Sportsmen’s groups…of outdoor magazines…of conservation groups…of the SCIENCE behind bird populations, predators, and habitat. If you truly want to save your resource and stop playing political games because you’re “liberal” or “conservative”…follow the FACTS. Then petition Noem to stop this nonsense and instead focus on habitat conservation efforts.

Wow.  Traffic on my blog literally shot up ten-fold since I posted about the idiocy of Kristi Noem’s predator control program in South Dakota. And with that traffic of course comes the haters, with direct emails to me, and attempted blog replies that offered nothing more than name calling. Not surprisingly, most were from hunters.  If you can get past the four-letter words and try to make some sense of some of the emails I’ve had, the general thought is that killing skunks, opossums, red fox, and raccoons is very helpful for Ring-necked Pheasant populations. And thus, these hunters are all for Noem’s little misguided foray into “conservation”.

Let’s look at the facts. Do you like to hunt Ring-necked Pheasants? Chances are you support groups like Pheasants Forever? Here’s what Pheasants Forever has to say about predator control programs:

Stating an investment in increased habitat is FAR more effective than predator control in improving pheasant populations, they state:

Less-expensive methods to improve game bird populations and nesting success exist. Experts have focused on the amount of habitat (composition of the landscape) and the arrangement (configuration) that increase nesting success by reducing the effectiveness of predators. Well-designed habitat projects can reduce predation by up to 80 percent.

Regarding predator control, they state it’s ineffective at helping broad-scale pheasant populations…and in fact, it may INCREASE interactions among predators and pheasants:

It is important to understand that sustained trapping efforts tend to stimulate reproduction by predators (compensating for artificially low densities) and create populations with proportionately more juveniles that wander more across the landscape thereby increasing the chances of encountering pheasants.

Overall, here’s their summary statement on predator control, and where money SHOULD be spent…on habitat restoration:

While predator removal and exclusion methods can increase nesting success on small areas, these methods are too expensive for use on a landscape basis and do not significantly increase the number of nesting birds over the long term. Through the addition and management of habitat, we not only decrease the impact predators have on existing nests, but also increase the number of nests and population size in an area. Predators will continue to eat pheasants and their nests, but weather and habitat conditions will drive population fluctuations.

What’s laughable about Noem’s program is that she ignored the advice of her own people, and ignored past research in South Dakota that has focused on Ring-necked Pheasant populations. Former Governor Daugaard held a “Pheasant Habitat Summit” in 2013 and followed up by commissioning a “Governor’s Pheasant Habitat Work Group”.  You know…actually investing in RESEARCH and DISCUSSION before unilaterally making a bad decision to start a predator control program. Land owners, hunters, and government personnel participated. Regarding predator control, the working group found that “When suitable habitat is available and weather conditions warrant, pheasant populations flourish without direct predator control“. Even when a misguided bounty program like Noem’s is established, they found “Bounty systems in other states have been ineffective because the origin of the predators cannot be verified”.

More information from sportsmen’s groups.  Midwest Outdoors published a piece on the “5 widespread myths about pheasant and quail populations“. One of those 5 myths is shown below:

Myth: Predators are the main reason there are fewer pheasants and quail.

Busted: Yes, coyotes and fox will eat pheasants and quail, and raccoons and skunks are likely culprits when it comes to raided nests. But predators don’t eat habitat, which is far and away the biggest reason why pheasant populations decline. High annual losses to predators should not be misunderstood to mean that predation is responsible for long-term upland population declines. Landscapes with good habitat often have high numbers of pheasant numbers, as well as high numbers of many potential predators.

 

The impact of predators is magnified and often pinpointed as the primary problem after habitat conditions deteriorate. Confine pheasants and quail to smaller and smaller parcels of habitat, and a predator’s job gets a whole lot easier. Thankfully, well-designed habitat projects can reduce predation by up to 80 percent. Through the addition and management of habitat, not only does there tend to be a decrease in the impact predators make on existing nests, but more habitat is likely to increase the number of nests and the overall gamebird population. And habitat for pheasants and quail comes at a fraction of the cost of other intensive predator reduction methods that are cost-prohibitive across a large area.

Just like Pheasants Forever, they note it’s HABITAT that’s the key, and if you have adequate, well designed habitat, that alone decreases nest predation by predators. And just like Pheasants Forever, they note it’s a FAR bigger “bang for the buck” in using conservation dollars to promote pheasant populations.

Another sportsmen/hunting group, Quail Forever, states the following (hint…it ‘s similar to statements from all the other groups:

Bottom line: Through the addition and management of habitat, we not only decrease the impact predators have on existing nests, but also increase the number of nests and population size in the area. This management comes at a fraction of the cost of other predator reduction methods.

MORE HABITAT, LESS PREDATION, BEST OUTCOME
Less-expensive methods to improve game bird populations and nesting success exist. Experts have focused on the amount of habitat (composition of the landscape) and the arrangement (configuration) that increase nesting success by reducing the effectiveness of predators. Well-designed habitat projects can reduce predation by up to 80 percent.

 

Programs such as Noem’s may actually do more HARM than good for Pheasant populations. For example, red fox are noted as the most effective predators on Ring-necked Pheasants, by our own Game Fish and Parks. But red fox populations are quite low in South Dakota, as they simply cannot compete with Coyotes. There’s a direct, inverse relationship between high coyote densities and red fox densities. As this story notes, hunters wrongly blame coyotes for predation on Ring-necked Pheasants, but our own Game Fish & Parks notes Coyotes have a minimal impact on Ring-necked Pheasant populations. Human intervention in removing predators results in unpredictable impacts on other wildlife, and ironically, hunters calling for removal of Coyote should note that would likely HARM Ring-necked Pheasant populations, as Coyotes not only help keep Red Fox populations low, but also help control other small mammalian predators on Ring-necked Pheasant nests.  This isn’t just one isolated case of an unintended consequence of predator control programs. Some other studies note that predator control programs focused on creatures like red fox simply create more of an ecological niche that other predators come in and fill, such as feral cats.

The one common thread from our own GFP…from Pheasants Forever…from Quail Forever…from all groups associated with conservation and wildlife management…NOTHING has anything close to the impact on Ring-necked Pheasant populations as 1) habitat, and 2) climate. So what factors could contribute to any perceived decline of gamebirds in South Dakota. HABITAT LOSS.  Starting in the mid-2000s, the eastern Dakotas have seen an expansion in cropland that literally rivals rates of deforestation in the tropical rain forests.  Here are multiple studies that have quantified recent grassland loss in the Dakotas:

  1. Wright and Wimberly (2013) found a net loss of 1.3 million acres of grassland that resulted from conversion to corn or soybeans in five states comprising the western Corn Belt over the five years from 2006 to 2011.
  2. Johnston (2014) also used the CDL to analyze land cover trends across the eastern Dakotas and found that corn and soy agriculture expanded by 27% (3.8 million ha) during the two years from 2010 to 2012.
  3. Reitsma et al. (2015) reported a net grassland loss of 4.6 million acres resulting from cropland expansion in the state of South Dakota over the six years from 2006 to 2012.

 

I’m a scientist. I look at evidence. I look at FACTS. The FACTS couldn’t be clearer.

  1. Predators aren’t driving any broad-scale decline in gamebirds such as pheasants. 
  2. Habitat loss is far and away the biggest concern for gamebirds (and other wildlife) in the Dakotas
  3. Predator control problems are expensive and ineffective, with a miniscule impact compared to dollar-for-dollar habitat conservation efforts.

I’ll end with one more driving factor for the long term…climate change. As noted above, conservation and management groups all noted TWO factors that had the biggest impact on gamebird populations..habitat, and weather/climate. The climate is changing…whether you “believe” in it or not.  What are the potential impacts on gamebird populations in South Dakota? Let’s look at Sharp-tailed Grouse populations in the state.  They are found from the southern to northern border in South Dakota, in much of the western half to two-thirds of the state. They are found as far south as the Platte River in Nebraska. What about the future?

Using projected changes in both land use (habitat loss) and projected changes in climate, this (wonderful!!!) study found that your grandchildren aren’t going to be hunting Sharp-tailed Grouse. Not in South Dakota anyway.  The top map below shows the “current” distribution of Sharp-tailed Grouse. The areas in red in the bottom three maps? Those all show areas where Sharp-tailed Grouse will be severely impacted by climate and land use change…with a bulls-eye right on South Dakota and northern Nebraska. Three climate scenarios are shown, with “A2” being the most severe scenario, and “B1” being the least severe. REGARDLESS of scenario, this research shows that SHARP-TAILED GROUSE WILL BE EXTIRPATED FROM THE SOUTHERN TWO-THIRDS OF SOUTH DAKOTA BY 2075.

Sharp-tailed Grouse - Tympanuchus phasianellusSo please, sportsmen…if you want to preserve your resource, do ALL of us some good. Predator control? NOBODY (other than our rather clueless governor) believe it’s an effective long-term solution. You want a big bang-for-the-buck? Petition Noem’s office for habitat conservation and preservation programs. Contribute to groups that foster habitat protection. That’s a “win” for all concerned, as it not only benefits Ring-necked Pheasants and reduces predation, but it helps non-game species as well.

And if you’re like me and have a son…and if you worry about his future…play the long game as well, and start paying attention to the long-term devastation climate change is going to have in the state.

Ring-necked Pheasant - Phasianus colchicus

A young Ring-necked Pheasant hanging out on a fence post. Do you want to preserve these birds, and also end up helping ALL wildlife in the state? Stop supporting this ridiculous predator control effort, and focus the state’s attention on habitat conservation.

Birding central South Dakota

Author: DakotaBirder • Discussion: No Comments

Bald Eagle - Haliaeetus leucocephalus

A Bald Eagle in flight, taken just north of Kennebec, South Dakota. I saw over a dozen of these guys today on the grasslands, and area far from any large water body. I’ve found multiple huge eagle nests in the area in recent years, as they’ve obviously learned that with all the pheasants, grouse, and prairie chickens in the area, it’s a GREAT place to raise (and feed!) a family!

Today was “the” day.  Once or twice a winter, I’ll get up ridiculously early, drive three hours to the central part of the state to ensure I get there right at dawn, and spend the day birding.  What could possess anyone to head to central South Dakota before dawn in the middle of winter?

Winter raptors!  As I’ve said many times, central South Dakota can be truly spectacular for raptors during the winter time.  That surprises a lot of people.  Winters can be pretty damned harsh up here…the blizzard that shut down the western half of the state for the last 2 days is a great example!  In eastern South Dakota in winter, near Brandon where I live, if I drive rural areas I’m not likely to see much for bird life.  The best I can usually hope for is to run across some flocks of Snow Buntings or Lapland Longspurs, but for the most part, all the crop land in the eastern part of the state is pretty dead in the winter.

It’s dramatically different in the central part of the state.  The reason?  Better habitat with cropland interspersed with a lot of open grassland, and more importantly, plentiful prey!  Ring-necked Pheasants, Sharp-tailed Grouse, and Greater Prairie Chickens are beyond abundant in many parts of central South Dakota, and attract raptors that can take such big prey, including many eagles (Bald and Golden), Ferruginous Hawks, Gyrfalcons, and more.  The wide-open grasslands of the region also hold many large flocks of Lapland Longspurs, Horned Larks, and Snow Buntings in the winter, smaller prey that are favorites for Merlins and Prairie Falcons.  It doesn’t seem to matter the weather, most of the time when I head out there, there are a lot of fat and happy raptors!  That was evident again today, as it was quite obvious (from the full crops on several birds) that the birds were feeding quite well!

There are two general areas I like to bird in the central part of the state: 1) The Presho/Kennebec corridor near I-90, and 2) the Fort Pierre National Grasslands to the north.  As with most of my central South Dakota trips, I timed my drive today to arrive at Presho right around dawn. My day of birding usually begins with the area just south of Presho, an area that’s been truly magical for me for winter raptors in recent years.  The big attraction for raptors are the game birds in the area.  There are a number of hunting operations in the area, many of which release pheasants for hunters.  There have been times in the winter where I’ll 100-200 Ring-necked Pheasants milling about in a field, and there are plenty of Sharp-tailed Grouse in the area as well.  Today got off to a rocky start as it was uncharacteristically slow in the Presho area. Right upon arriving, I came across a Merlin feeding on a small bird (most likely a Horned Lark), and I did find a couple of Bald Eagles south of Presho, but the Rough-legged Hawks that usually are EVERYWHERE in winter were curiously absent.  I spent more time cruising random gravel roads in Presho and Kennebec area this morning and picked up a stray raptor here or there, but it was a depressingly slow start for the day.

Rough-legged Hawk - Buteo lagopus

A Rough-legged Hawk just after taking flight from a telephone pole. These guys are always the undisputed “kings” of the prairie in winter, at least in terms of sheer numbers. Today’s count of 32 Rough-legged Hawks was actually a bit of a disappointment. I’ve had some winter days where the count has been more than twice that.

Given the lack of action near Presho and Kennebec, I started to drift northward towards the Fort Pierre National Grasslands.  It soon became abundantly clear that the blizzard from this weekend took a increasingly greater toll the further you moved north from I-90.  Gravel roads are usually somewhat immune to freezing rain, but the amount of freezing rain and slush from this storm was truly amazing, and even gravel roads were smooth, slick mirrors in some spots.  It was even worse for birds in the area, though.  The grasslands were coated with a thick sheet of ice and slush, and many of the game birds in the area appeared to be struggling.  On the Fort Pierre National Grasslands themselves, I came across several huge flocks of Sharp-tailed Grouse and Greater Prairie Chickens, milling about in open grassy areas, searching for clear spots in the ice so they could forage. Despite all the potential prey, however, there were very few raptors on the grasslands themselves. The day wasn’t getting any better.

Something has happened on the Fort Pierre National Grasslands over the last 5 years.  5 years ago, winter raptor birding on the Grasslands was typically spectacular.  Scanning the fence posts and telephone poles, it was often unusual if you could drive a mile WITHOUT encountering a raptor.  Over the last 5 years though, the grasslands have been curiously devoid of raptors.  That again was the case today.  As slow as the birding was around Presho in the morning, it was MUCH slower on the Grasslands further north.  There are definitely fewer pheasants and grouse on the grasslands than in the area around Presho, but  the last 5 years have made me wonder if something has also happened to the small rodent population in the area.  It just seems odd that such consistently great birding for many years could nosedive and stay low for so long.

I admit that by noon, I was a little down.  An entire day devoted to birding the area, and it was pretty slow to that point.  I decided to head back down towards Presho and Kennebec again, and it soon became clear that there were PLENTY of raptors in the area, and that they were much more active than they had been in the morning.  Driving the gravel roads just north of Presho and Kennebec, the usually plentiful Rough-legged Hawks, a species that was almost absent during my morning search, were back in force (where had they been this morning?!?). Red-tailed Hawks were present in larger numbers than normal, and I ran into the occasional Prairie Falcon or Ferruginous Hawk as well.  One thing that surprises people is how common eagles are in the area in winter, both Bald Eagles and Golden Eagles.  There are multiple active Bald Eagle nests in the Presho and Kennebec area, in the middle of the grasslands and far from any large water body, while Golden Eagles that are absent in the area in winter often show up in good numbers for the winter.

Greater Prairie Chicken - Tympanuchus cupido

A Greater Prairie Chicken, searching for food in a prairie covered by a crust of ice and snow. Despite how common these are in parts of Central South Dakota, they’re actually a species I’ve never had any luck photographing! Not the greatest photo here, but at least I finally have something.

I didn’t run across any of the “special” winter raptors today. To me, the list of “special” winter raptors includes Gyrfalcon, Snowy Owl, and Short-eared Owl.  I’d estimate that I spot one of those species in about half of the trips I take to the area, but not today.  It was still a beautiful day for birding, and the final raptor count for the day ended up being pretty good.  Honestly, the tally here is a little lower than what I’ve normally experienced in the area in recent years, but that just emphasizes how truly spectacular winter birding has been lately!  The raptor count for the day:

  • Rough-legged Hawks — 32
  • Bald Eagle — 13
  • Red-tailed Hawks – 12
  • Golden Eagles – 5
  • Ferruginous Hawks – 4
  • Merlin – 4
  • Prairie Falcon – 3

 

While raptors are definitely the attraction for birding the area in winter, there have been some other trends in recent years that are certainly interesting.  I started birding 16 years ago, and during those first few winters when I would bird this area, it was always surprising to run across a stray Western Meadowlark here or there.  In recent years, it seems like more and more Meadowlarks stay in the area all winter long, and today, I came across literally hundreds and hundreds.  I also came across two large flocks of American Robins, a species that does sometimes overwinter in the area in small numbers, but there were probably at least 100 Robins in each flock I saw today.  Southeast of Presho, there also have been large numbers of Red-winged Blackbirds that have been overwintering in recent years.

Three different species of birds, each of which is found in ever-increasing numbers in winter over the last several years…hmmm…I wonder what the cause could be?  It’s almost as if there’s some kind of “warming” effect that’s enabling them to overwinter.  Perhaps someday scientists will discover what’s behind such a change in climate.  🙂

It’s a bird-eat-bird world

Merlin (Falco columbarius) with prey (Horned Lark)

A Merlin munching on a freshly caught Horned Lark

It’s Saturday.  I went birding on Monday.  But as is typical, I didn’t even download or start to look at the photos until this morning.  Heck, this is actually FAST for me! I have folders upon folders of bird photos that await.  It’s a lot more fun to take photos than to process them and get them up on a website.  What I’ll often do is just process a few of the best ones and leave the rest for a “later” time period that often seems to never come!  Some day I’ll start my own personal digital birding adventure, where I’ll revisit all my old photos and rediscover ones I never knew I had.

But in the meantime, here’s a few from Monday.  As I like to do a couple of times I winter, I got up early Monday and made the long drive to the central part of the state.  It was a LOVELY day for birding, at a slightly crisp -17 degrees when I arrived at dawn.  One of my favorite birding locations and times in South Dakota is the area around Presho in the dead of winter.  There are many pheasant hunting operations in the region, and a fair amount of land managed for pheasants and grouse.  With literally hundreds of pheasants and grouse sometimes milling about, winter raptors are attracted to the area.  The density and diversity is usually spectacular.  It’s a guarantee you’ll find Golden Eagles, Bald Eagles, Northern Harriers, Red-tailed Hawks and Rough-legged Hawks, you’ll usually find Ferruginous Hawks and Prairie Falcons, and you’ll often find some of the more “fun” species, including Gyrfalcon, Merlin, Snowy Owl, or Short-eared Owl.

Northern Harrier - Circus cyaneus

A female Northern Harrier, feeding on the scant remains of a pheasant

By “Presho standards”, Monday wasn’t the greatest, as I “only” came across 75 or so raptors over the course of 7 hours.  No rarities, but I did get some very nice looks at nature in action.  Merlins are a species I don’t see very often, at least not in my part of eastern South Dakota.  But for some reason I often have luck finding them around Presho in the winter. It’s not just all the pheasants and grouse that attract raptors, ti’s also Horned Larks, Lapland Longspurs, and other small birds that often frequent the area.  The photo here is a Merlin munching on a freshly caught Horned Lark (they seem to be a favorite prey species).

The second photo is a female Northern Harrier. I came across her feeding on the remains of a pheasant carcass on the side of the road.  I’m not sure if Harriers take down full-grown pheasants or not…it seems like they’d be a handful.  But I have seen Harriers on carrion, so perhaps this one was feeding on the remains of a bird caught or killed by something else.  It was nice to get relatively close looks at her though, as Harriers around here are typically quite skittish.  For as many as I’ve seen, I don’t have all that great of photos of them.

It’s a rough world out there!  Eat or be eaten!

Difficulty finding grassland birds in (former) grasslands

Author: DakotaBirder • Discussion: No Comments

Blue Grosbeak - Male - Passerina caerulea

Male Blue Grosbeak. These guys are scattered around in southern South Dakota, but it’s always a bit of a surprise when you run across one. Yesterday west of Lake Thompson I saw three in one small area.

Eastern South Dakota was once >95% grassland and scattered wetlands.  Trees were limited to riparian areas or pockets where the landscape was protected from the tree-killing effects of fire, and of course, there used to be no agriculture or urban land use.  Now of course the story is completely reversed, as pockets of unbroken grassland are rare in many parts of the state, as cropland has become the dominant land use.  In an area where grassland used to be king, it can now be quite difficult to find some of the traditional grassland bird species.

For some species, such as Sharp-tailed Grouse, they’re forever gone from most of eastern South Dakota. For other bird species, they’re found scattered in pockets of remaining suitable habitat.  Right around Sioux Falls, there simply isn’t a lot of grassland.  The Conservation Reserve Program (CRP) does provide farmer payments in multi-year contracts in return for keeping the land in a grassland cover, but in recent years, CRP has sharply declined in the Dakotas, with the demand for corn and soy driving extensive expansion of cropland at the expense of what pockets of grassland remain.  For birds like Bobolinks, Grasshopper Sparrows, and Upland Sandpipers, you’ll occasionally find one in a small remaining pocket of grassland, but there’s very little in the way of a “go-to” for place for birds, with extensive grassland, right around Sioux Falls.

Bobolink - Male - Dolichonyx oryzivorus

Male Bobolink. Kind of a scruffy looking dude, but nice to get so close to one as they’re normally shy for me. These guys were numerous where I went birding yesterday.

In South Dakota, the three counties where I bird the most are Minnehaha (where I live), Lincoln (just a few miles south), and…Kingsbury County.  Kingsbury County isn’t even adjacent to Minnehaha or Lincoln county…in fact it’s well over an hour drive to even get to the edge of Kingsbury County.  The attraction of Kingsbury County for me is two-fold. Lake Thompson is the largest natural lake in South Dakota,and the region has extensive open water, shallow water habitats, mudflats, and wetlands.  The other attraction for me is the west side of Lake Thompson.  There are some very large cattle operations in the area, and instead of cropland, much of the land is kept as grassland and pasture.  There are also large areas of alfalfa fields.  Unlike many pastures around here that are overgrazed to the point of erosion becoming a problem, the land in this area seems pretty well managed, with a mix of taller grasslands and (seemingly) responsibly grazed grasslands.

The result is one of the best areas I know in the general vicinity for finding grassland birds.  I drove the area yesterday on a GORGEOUS, sunny, cool day, and was just reveling in the sounds and sights.  There’s one particular road that’s now closed due to fluctuating water levels on Lake Thompson itself. The road gets no traffic and isn’t maintained much anymore, but it’s no problem for my little pickup.  No people, some very nice grassland habitat, and some wonderful birds.  This is one of the few places around here where I can reliably find Upland Sandpipers.  If you go to the central part of the state, Upland Sandpipers are seemingly on every other fence post in the big grassland areas.  You just don’t see them all that often in much of eastern South Dakota, so it’s always a treat to find them here.

Orchard Oriole - Icterus spurius

Orchard Oriole male. Never have I seen such a concentration of Orchard Orioles as I do in this area west of Lake Thompson. Such beautiful little birds, an oriole many folks may not even know are around here.

Singing Bobolinks are another big attraction for me for this area.  I sometimes see (and hear) Bobolinks right around Sioux Falls, but it’s nearly always a single bird, trying to utilize a small remaining piece of pasture or an alfalfa field.  On the west side of Lake Thompson you hear them singing everywhere…one of my favorite sounds in the world, with their long, tinkly songs.  Both Eastern and Western Kingbirds are numerous, seemingly always fighting for fenceline foraging and perching rights.  It’s a place where I see Orchard Orioles in numbers I’ve never seen elsewhere.  The bug-like calls of Grasshopper Sparrows sound out from their hidden perches, as do the buzzy songs of Clay-colored Sparrows.  It’s the same kind of experience you sometimes find in areas of extensive grasslands in the central part of the state, such as on the Fort Pierre National Grasslands, but it’s so much closer to home.

A wonderful day! I just hope the land in that area continues to be managed as it is right now, and that it too doesn’t succumb to the ever expanding cropland in the area.
