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:

Scarlet Tanager - Piranga olivacea
Scarlet Tanager – May 18th, 2019 Good Earth State Park, South Dakota
Magnolia Warbler - Setophaga magnolia
Magnolia Warbler – May 18th, 2019 – Good Earth State Park, South Dakota
Henslow's Sparrow - Ammodramus henslowii
Henslow’s Sparrow – May 19th, 2019 – Newton Hills State Park, South Dakota. Great weekend of birding overall, AND a lifer? I’ll take it.
Great Crested Flycatcher - Myiarchus crinitus
Great Crested Flycatcher – May 18th, 2019 – Good Earth State Park, South Dakota. Flycatchers in general seemed almost non-existent, prior to this weekend.
Mourning Warbler May 18th, 2019 Good Earth State Park, South Dakota. Not a great photo, but Mourning Warblers are a species I see occasionally, some springs. On May 18th, I ran into probably a dozen at Good Earth State Park.

Eagle Convention at Splitrock Creek

After 17 or so years of using one lens for bird photography (a Canon 400mm 5.6L), I ordered a new lens that arrived Monday…the Canon 100-400mm 4.5/5.6L IS II that I’ve mentioned previously.  The timing was fortuitous, as late this week we’ve had something rather unprecedented happen for the area around our little town. We’ve had severe flooding, flooding which is actually supposed to get worse early next week as all the snow pack north of us melts. Splitrock Creek runs through our little town of Brandon, and in the wake of the flooding it has left massive ice chunks all along banks and roads near the river. But it also left scads of dead Asian Carp and other fish.

Seemingly overnight, the area around our town has been inundated with Bald Eagles. We actually have an active Bald Eagle nest less than a mile from our house, a nest that’s been used continuously for about the last 6-7 years.  It’s not rare to see one or sometimes even two Bald Eagles while out and about near our town. Today however, I was on a bridge over Splitrock Creek, and from that one spot I counted 29 Bald Eagles. In…one…spot.  There have been eagles in varying concentrations all along a 10-mile stretch of Splitrock Creek that I’ve checked out this week.

When I started birding 20 years ago, I still remember seeing my first Bald Eagle along the Big Sioux River near Canton. I remember the excitement of seeing such a majestic bird. It’s amazing how rapidly their numbers have increased in the last few decades, as I can now be in any part of South Dakota, in any season, and it’s not a surprise to see one or more Bald Eagles. Even when I visit the grasslands in the central part of the state, an area that is far from any significant river or lake, I find Bald Eagles, sometimes in big numbers. A true success story for American conservation!  But even on a night like tonight where eagles are seemingly everywhere, it’s still a thrill to see and photograph these birds.  Some photos from today:

Young Bald Eagle - Haliaeetus leucocephalus

Young (3rd year?) Bald Eagle, flying over Splitrock Creek near Corson, South Dakota. However, it’s not just young birds that are in our area right now. In fact, a majority of the Bald Eagles I’ve seen in the last few days have been fully mature birds.

Bald Eagle - Haliaeetus leucocephalus

A mature Bald Eagle flying over the trees near Brandon. There were plenty of mature Bald Eagles around, but they were seemingly shyer than the young birds.

Bald Eagle - Haliaeetus leucocephalus

Another young Bald Eagle sitting on a tree stump northeast of Corson. While most birds are along Splitrock Creek, there are so many birds around that they seem to have spilled out onto the surrounding farmland as well.

Bald Eagle - Haliaeetus leucocephalus

A mature Bald Eagle hanging out on a chunk of ice left behind by the flooding at Splitrock Creek north of Brandon. This is perhaps the most common “perch” for these guys right now, as most of them that I’ve seen have been among the ice flows, where the dead fish are concentrated.

Bald Eagle - Haliaeetus leucocephalus

A long-distance shot, but it gives you an idea of the concentration of the eagles. There are 10 in this one shot, sitting on stranded ice blocks on a sandbar in the receding Splitrock Creek. This is the location where I saw 29 birds at once today.

Bald Eagle - Haliaeetus leucocephalus

An even longer-distance shot, showing a common sight in the trees near Splitrock Creek this week. There are 8 birds in this one tree, but it’s this group of trees where a local farmer told me there were 75 roosting overnight earlier this week.

Burrowing Owl? Here?!? POTD – From 10 years ago today

It was 10 years ago when I had one of my better birding moments. There are always those great trips to “new” places that get the birding juices flowing, but one of the best aspects of birding is that you never know what you might see when you go out.

It was 10 years ago that I was coming back from a business trip. I flew into the Sioux Falls airport and was driving back to my little home town of Brandon (about 6 miles west of Sioux Falls). I was driving by an open alfalfa field, when I noticed a bird on a post.  It was a…no…couldn’t be…yes! a Burrowing Owl!  Here in far eastern South Dakota, just a few miles from Minnesota. Historically Burrowing Owls used to be around here, but there hadn’t been a breeding record of Burrowing Owls anywhere close to here in decades.  Our grassland is gone, and we just don’t have the prairie dogs or other creatures that Burrowing Owls are often found with.  Yet here was an adult Burrowing Owl, hanging out on a fence post, in early August.

I quickly drove the last 4 miles home, got my camera and returned. Upon looking around I saw another Burrowing Owl…and another…and another.  There were two adults, and at least four young!! It didn’t take long to find their home. They were using an old badger hole, in the middle of the alfalfa field by the road.  The young were already as big as the parents, although with a different plumage. I had a blast for the next month, watching the little Burrowing Owl family feed on grasshoppers, crickets, and other little critters, primarily using a big CRP (?) grassland that was right next to the alfalfa field. By early September they started disappearing, one by one.

That alfalfa field is now on a corn and soybeans rotation. The CRP field they were using to forage? Also plowed under, used for corn and soybeans. In the 10 years since, I’ve never again seen a Burrowing Owl anywhere close to  my part of the state. But I’ll always remember the little Burrowing Owl family that successfully fledged several young, just 4 miles from my house.  Here’s one photo I took at night, of one of the adults foraging for insects alongside the road.

Eurasian Tree Sparrows!! In my Yard!!!

Eurasian Tree Sparrows!  In my freakin’ yard!!  News at 11:00!  More later!!

EDIT: The story…I WAS going to go work in the office today, but woke up in the middle of the night with a massive headache. I thought I’d take it easy and work at home today.  About 10:45 this morning, I looked out the sunroom window. I saw a bird in the back of the yard that looked…odd. I grabbed the binoculars, and as I started to focus on it, the bird flew…right towards me, landing in the crabapple standing 10 feet from the window.  Immediately you could see it was something different…it was NOT a House Sparrow!  It was a Eurasian Tree Sparrow!

I gawked for a few seconds, and then grabbed my camera that fortunately was only a few feet away. As I started snapping photos, ANOTHER Eurasian Tree Sparrow popped up in the same tree!  One seemed to be following the other. At first, I thought they were both male birds, but only because I assumed they had a sexual dimorphism similar to House Sparrows.  Only later did I find that no, both males and females are similar in appearance.  Given the way the two birds moved together, with one always following the other, my best guess is that they were a male and female.

They stayed in the tree for perhaps 1 1/2 minutes, during which I took as many photos as I could.  During the rest of the day, there were only two other, brief sightings in my yard (one bird each time).

Why is this a big deal? They DO look somewhat similar to our everyday House Sparrow. However, Eurasian Tree Sparrows have a unique history. A  small number were released near St. Louis, Missouri in 1870 by a landowner who wanted to replicate the bird life of his native Europe. IN the 148 years since then, Eurasian Tree Sparrows haven’t expanded their range much beyond their original release location. They have still almost exclusively been found in far western Illinois, far eastern Missouri, and far southeastern Iowa.  In recent years, stray sightings have occurred outside this range, including areas as close as Minnesota.

But until the last 2 weeks, no live Eurasian Tree Sparrow had ever been seen in South Dakota.  A couple of weeks ago, the Small family in Vermillion saw an individual bird…the first live Eurasian Tree Sparrows ever seen in the state (a deceased bird was once found)!! The two birds in my yard today thus represent only the 2nd time the species has been seen in the state.

Pretty cool!! Here’s hoping the two are a mating pair, and that they stick around my yard for the summer.

Checking in on the neighbors – Nesting Bald Eagles

Nesting Bald Eagles - Haliaeetus leucocephalus

A photo from a couple of days ago, with one of the adults sitting on the nest. They’ve been doing so for over a month now, and with the leaves not yet out on the cottonwood tree, it’s a wonderful time to observe them from afar. Click for a larger view.

As far as neighbors go, you could do worse than a pair of nesting Bald Eagles. These neighbors moved in about 10 years ago, building a massive nest in a huge cottonwood tree along the Big Sioux River, less than a mile from our home (a mere 4,400 feet as the crow flies, according to Google Earth!). The first nest lasted a year or two before a flood event felled the big cottonwood, but thankfully, they responded by simply picking another big cottonwood and rebuilding the nest.

If you haven’t seen a Bald Eagle nest, it’s a damned impressive structure!  They continually build it up, and it’s pretty amazing to see the size of some of the branches they try to pick up and incorporate into the nest. The nest now has to be 10 feet across, and keeps growing each year. And why not? It seems to be working for them, as they appear to have successfully raised a number of broods over the years.

This year, they’ve been sitting on the nest for a least a month, and I’m sure they once again have eggs.  I haven’t seen any lil’ heads poking up yet, so I’m not sure they’ve hatched yet.  Now is the perfect time to observe them, and I often have seen the young in the nest. But alas, in a month the cottonwood will have leafed out and made direct observation much more difficult. Often then the next observations you get of the young themselves is when they fledge from the nest, but they always hang around the same tree for quite some time afterwards.

Very cool neighbors! And neighbors that I’d bet most people don’t know are there. The nest itself is hard to miss, given it’s massive size.  You can easily see it from the north-south highway running through our town of Brandon. But people around here are always surprised to hear that we have such majestic birds nesting right on the edge of town.

Nice winter birding

Yeah, a month since a post. It’s been a bad month on multiple fronts, wasn’t in much of a mood to bird, rockhound, or blog. It HAS been a really nice year for some of the more uncommon winter bird visitors in South Dakota though, so this morning I went out and about, just around Brandon and Sioux Falls.

A nice morning! The highlight were a number of White-winged Crossbills. They are a nomadic species, found in one place one year, gone the next. They are pretty rare visitors to our neck of the woods, but one place they can occasionally be found is Mount Pleasant Cemetery in Sioux Falls. It’s an old cemetery, with some really huge, old spruce and other evergreens. The spruce have a really thick crop of cones this year, which is what attracts the Crossbills.  A really busy morning for birds in the cemetery, not only the rare White-winged Crossbills, but scads of Pine Siskins, and at least a dozen Common Redpolls as well.  There are entire winters that go by where I don’t see those 3 species, so it’s been a really nice treat this winter.

Some photos, including a few from around the yard recently…

White-winged Crossbill - Loxia leucoptera

A White-winged Crossbill hanging out in a spruce tree. They were really active this morning, moving from tree to tree in mixed flocks with Redpolls, Pine Siskins, and a few nuthatches. The problem was their preference to forage near the top of the massive spruce trees! I had to be patient to get one low enough for a photo.

White-winged Crossbill - Loxia leucoptera

Another White-winged Crossbill, foraging in the same place as the previous photo.

Northern Cardinal - Cardinalis cardinalis

The male Northern Cardinal that visits my yard every day. Like clockwork, both a male and a female show up in the last 20 minutes of daylight, and occasionally at other times as well.

Common Redpoll - Acanthis flammea

A Common Redpoll eating the seeds in the catkins that dangle from my paper birch in the back yard. They LOVE paper birch catkins, and already this winter have pretty much finished all the catkins of the tree. This is only the 3rd winter (in over 20+ years in Brandon) where we’ve had Redpolls visit.

Northern Cardinal - Cardinalis cardinalis

The female Northern Cardinal that always visits in the evening.

Pine Siskin - Spinus pinus

One of the scads of Pine Siskins in my yard. I’ve occasionally had 1 or 2 come to the feeder in winter. I’ve NEVER had them like this. They have been by far the most common bird in my yard, even outnumbering all the goldfinches that love my thistle feeder. There have been times I look out and there are 50 or more, hanging out in my paper birch, and foraging at my feeders.

Hanging with the Hummingbirds…

I was planning on doing some birding yesterday, but life got in the way. I started doing yard work, and couldn’t help but notice several Ruby-throated Hummingbirds flitting through my back yard, moving from flower to flower, and to my one nectar feeder.  After finishing the yard work, I decided to do something I haven’t done all summer…try to get photos of my visiting hummingbirds.

They’re not going to be around much longer.  They’ll start to leave in a week or two, and numbers will dwindle.  By September, I’m usually only left with occasionally young birds and females. By mid-September, they’ll largely be gone.

I’m always so excited when the first hummingbird shows up in our yard in early May!  I figured I’d better take some time and enjoy them while we can.  For now, here’s a male and female (or young) visiting my nectar feeder.

Ruby-throated Hummingbird - Archilochus colubris

A somewhat scruffy looking male Ruby-throated Hummingbird. I probably won’t have males around for too much longer. Mature males are always the first to leave, and will be scarce or absent by the end of the month.

Ruby-throated Hummingbird - Archilochus colubris

A female (or immature) hummingbird. Pretty soon these will all I’ll have, and then sadly, they’ll trickle away as well, leaving me with a long, 8-month period without my beautiful little hummingbird. 🙁

 

World’s most expensive dog bowl

Our two beloved spaniels, Oscar and Felix, are rather quirky. Given that they were originally found living by themselves in the wild, they were used to trying to find food, shelter, and water in the outdoors.  In the couple of years since we got them, they’ve become truly wonderful, sweet, loving pups, although they’ve maintained several of their original quirks.

The most maddening to deal with…their refusal to drink water if it’s inside the house. One of the two will sometimes drink from a water bowl inside the house, but strongly prefers drinking “outside water”.  The other?  There were a couple of days last fall, after I’d put the birdbath away for the winter, before there was any “delicious” snow to eat for a water source, where Oscar was refusing to eat much.  Even offering some of his most decadent, beloved treats…like some fresh cooked chicken breast…resulted in a turned up nose.  Wondering if the issue might be water, we placed a pan of water outside.  When we let the two outside, Oscar timidly approached the water, and then proceeded to guzzle the entire pan.  We let them back in the house, tried food again with Oscar, and he downed an entire bowl full.

It’s been maddening to try to get them to drink water, but my bird bath outside has always been their preferred drinking source, from the very first day we got them. However, that bird bath recently broke.  The only solution? Replace it with what’s got to be the world’s most expensive dog bowl (video at the bottom)!  I truly love this fountain…it’s from “Henri”, called their “Phoenix” fountain. It’s got a unique, modern style, has a big deep reservoir that holds a lot of water, has a wonderful shallow pan on top that the birds love to bath in, and most importantly, it’s very low and accessible for the pups!  And expensive, and back-breaking solution to get the dogs a reliable drinking water source!

Oscar and Felix - Birdbath

This is from the very first day we got Oscar (left) and Felix (right) from the rescue group. Almost immediately they found the joys of the bird bath, and for the last 3 years, it’s been their primary summer drinking source. Alas, this is the same bird bath that recently broke, requiring a replacement with the NEW world’s most expensive dog bowl.

Headed back north! Geese migration

Wow…And I thought the goose migration was incredible a few weeks ago when it started. Then came the cold weather, all the lakes froze over again, and they…disappeared.

Evidently many either stayed down south or moved back down south for a while, because with the warmer weather today, the migration has been incredible. I’m working at home, sitting in my 2nd floor office, looking out the open window, and for over 2 HOURS now, it’s been a constant stream of geese moving north. Snow Geese, Greater White-fronted Geese, and Canada Geese. Spring has sprung! And hopefully this time, it sticks!

Facts trump Fear: A FACT-based assessment of Mountain Lions in South Dakota

Mountain Lion - Puma concolor

A full-grown Mountain Lion on the prowl. No…no…not my photo! This is a wild animal roaming in Yellowstone National Park. You see, like 99.999% of South Dakotans, I will never see, much less photograph, a Mountain Lion in this state. That, despite Mountain Lions seemingly posing as much of a threat to human health and safety as disease, war, famine, and pestilence combined. At least in the minds of many misguided South Dakotans.

I should just avoid the internet.  My blood pressure might be greatly improved if I were able to do that. It’s bad enough that we have Orange Hitler as our president, with a bunch of mini-Hitlers running all of the Cabinet departments. It’s bad enough that the normal news outlets that I check every day, such as the Washington Post or the New York Times, are now dominated by depressing and often downright sickening news stories about how everything that makes America, America, is now being being systematically dismantled.  What’s worse is that the same “alternative facts” political world we live in has permeated EVERY facet of American life, where fact, reason, and logic mean absolutely nothing any more.

Yesterday I was on Facebook when I came across a South Dakota “gentleman”, posing with a huge shit-eating grin on his face as he held up a dead Mountain Lion that he’d just shot and killed. OK, “gentleman” isn’t the word I want to use here, but I’m going to try to stay civil in this post.  Just the facts…so let’s call him “Gentleman Joe”.  It was a BIG mountain lion…160+ pounds…and evidently shooting a BIG Mountain Lion makes Gentleman Joe some kind of hero in the minds of many who were commenting on Facebook.  Normally I’d see something like that, roll my eyes, get a little sick to my stomach at the whole thought of it, and then move on to the next post. OK, who am I kidding…If you know me, you’d KNOW I was going to respond after seeing that.  As I I scrolled down, I noticed a manifesto from “Jim Bob” (I’m sure some relationship to Gentleman Joe, if not by blood, then by ideology).  Jim Bob was praising Gentleman Joe for the great kill, going on with his thoughts about just how much safer South Dakotans were thanks to his kill.

According to Jim Bob, the Mountain Lion horde of the South Dakota Black Hills are taking over the state. According to Jim Bob, it’s seemingly impossible to go outside in the Black Hills nowadays without the imminent threat of a Mountain Lion attack. In Jim Bob’s eyes, the proliferation of Mountain Lions in the Black Hills is akin to nuclear weapon proliferation during the Cold War, and evidently, poses just as much of a threat to humanity.  In Jim Bob world, it’s not safe to wander outside in the Black Hills. Gentleman Joe was indeed a god-damned American HERO for saving a scared South Dakota populous from the Mountain Lion scourge.

White-tailed Deer Fawn - Odocoileus virginianus

Yes, this IS my photo. I know what you’re thinking…TERRY! YOU HAVE A FAMILY TO THINK ABOUT!?!?! How could you risk so much getting this close to a dangerous killer? OK…ridiculous, you say? How much threat does a lil’ White-tailed Deer pose? SCIENCE MY FRIENDS! And the numbers don’t lie. THIS creature is MUCH more likely to kill or injure you than is a Mountain Lion. If you live in South Dakota, it’s not the creature at the top of the page that is a threat to your life.

I responded with facts, providing the TRUE story of Mountain Lions in the Black Hills, and their supposed threat to health and well-being of South Dakota’s citizens. Jim Bob, clearly not accustomed to facing the world of reality, threw a few half-hearted digital haymakers in Facebook response before slinking back to his hole.  He had nothing to respond with, no evidence to back his claims.  But as he departed the digital conversation, it was quite clearly that the barrage of facts I provided did nothing to change his mind. Those facts?

There’s been a grand total of ONE…count them…ONE confirmed Mountain Lion attack IN THE ENTIRE RECORDED HISTORY OF SOUTH DAKOTA.

Even that one event, in 2008, was an unfortunate encounter that resulted from a lion defending a kill, rather than the lion actively seeking out a human being.  Ryan Hughes was ice fishing on Sheridan Lake in March of 2008 when he headed to the shoreline and came across a Mountain Lion crouched down in the cattails, feeding on a fresh kill (thought to be a fox).  When Hughes first spotted the Mountain Lion, he was a mere 5 feet from the lion and its kill. The surprised lion reacted, dropping it’s food and scratching and biting Hughes. Hughes received minor injuries, and was treated and released from a local hospital for minor scratches and bite marks.

Well over 150 years since settlement of South Dakota, and this one, chance encounter is the ONLY MOUNTAIN LION ATTACK EVER RECORDED ON A HUMAN BEING in the state. However, according to Jim Bob, it’s absolutely essential that “heroes” like Gentleman Joe actively thin out the Black Hills Mountain Lion population.  According to fearful, small-minded men like Jim Bob, it’s a matter of public SAFETY.

I have no doubt that for tiny-penis men like Jim Bob, Mountain Lions ARE something to fear (am I still being civil? OK it’s getting borderline). It’s a scary world when you’re an insecure, weak little man-child (yeah, definitely crossing the border now).  Toting a gun into the wild and blasting away at wildlife?  It’s great for boosting those testosterone levels and boosting the confidence of weak she-men like Jim Bob (I am WAY south of the border…bye-bye civility).  But stating Mountain Lion hunting must be done as a matter of public SAFETY?

Deer Collision Risk - State Farm

From State Farm Insurance, a table of the top 5 riskiest states for car/deer collisions. If only there were some natural predator capable of saving us from the Deer threat…

One attack in over 150 years, in a state that covers over 75,000 square miles. Depending on the estimate and year, recent estimates of the number of Mountain Lions in the Black Hills have varied from 200 to 400. Generally they’ve thought to have stabilized around 250 in recent years. It’s a very healthy, strong lion population, yet despite their substantial presence in an area that’s so heavily used for recreation, there just haven’t been any attacks on human beings, much less any serious injury or fatality caused by a Mountain Lion.  That fear from tiny penis she-men isn’t limited to people in the Black Hills region.  Even here at the opposite end of the state near my town of Brandon, there have been stories of fear from the likes of Jim Bob.

While permanent breeding populations of Mountain Lions in South Dakota are almost exclusively found in the Black Hills, wandering individuals are occasionally found elsewhere in the state and region, even here in southeastern South Dakota. In 2014, there were a few sightings of a Mountain Lion just north of Brandon, where I live. A lot of the reports are rather “bigfoot” like, such as a reported brief glimpse of what might have been a Mountain Lion in the headlights of a speeding car on a highway.  But according to this piece from 2014, some in the Brandon area believed that Mountain Lions were setting up shop in the region. A quote from one of the landowners just north of where I live in Brandon?

Those spottings are just a sampling of the evidence of what Heggen said is a long-running pattern of the lions, which are solitary animals, being a nuisance in his area.

Yes, Mr. Heggen. It’s a “long-running pattern” of Mountain Lions roaming the Brandon Area.  They are a long time “nuisance” here in extreme eastern South Dakota, an area that’s 90% corn and soybeans and unlikely to EVER host a Mountain Lion for any length of time. They have indeed been spotted from time to time. I even know of a guy at my work who has seen one in the area.  But as the story above notes, in 2013 there were only 6 recorded Mountain Lion sightings in the entire state outside of the Black Hills.  Only three of those were in the eastern half of South Dakota. It’s not exactly a “long-running pattern”, and it’s a far cry from Mountain Lions being a “nuisance” in the area. More quotes from the Brandon-area story:

“But we don’t have any raccoons, skunks, possums or even pheasants running around anymore. And for a while, we didn’t even see any rabbits, although we’ve seen a few smaller ones lately,” he said.

 

“I’m guessing they (the lions) are eating them,” Heggen said. “They aren’t scavengers like coyotes.” He said that what he fears most is having his 5-year-old son being harmed by one of the lions in their farmyard.

Mountain Lions Killed - American West

From the Mountain Lion Foundation, a graph of the number of Mountain Lions killed by hunters in the American West from 1900 to the present day. In the last 20 years, hunters have generally killed 3,000 to 4,000 lions a year. In South Dakota in 2017, Game Fish & Parks are allowing up to 60 Lions to be killed.

Once again, let’s return to the facts…ONE CONFIRMED ATTACK IN THE ENTIRE HISTORY OF THE STATE, yet people like this are evidently fearful for the lives of their families.  There are other ridiculously speculative comments in the story, such as one time some cows were spooked by something (clearly HAD to be a Mountain Lion, right?), or that one fall he didn’t see any deer while harvesting his corn (Eegads!  More Mountain Lions!!). Please spare me the anecdotal bullshit about all the poor little animals in the area disappearing, and attributing it to roving Mountain Lions. Trust me, we have PLENTY of deer, raccoons, skunks, opossums, pheasants, and rabbits running around this part of the state.  It’s hard to drive any road in the area and not notice all the road kill on the sides of the road.

I’m perhaps being a little (ok, more than a little) harsh on people like this, but as a scientist, my biggest pet peeve in this world are fearful, ignorant human beings who ignore fact, logic, science, and reason, and instead let their innermost fears and emotions rule their lives. The vast majority of people in the Black Hills, an area that may indeed have one of the highest Mountain Lion concentrations in all of North America, will never even SEE a Mountain Lion in their lifetimes, much less have an encounter or an attack.

I also realize it’s not just the fear of men (with tiny penises) that drives this hatred of Mountain Lions, and the “lionization” (ha-ha) and hero-worship of those who kill them. No, beyond the fear, it’s INSECURITY, and their need to KILL, to express their manliness, that also drives attitudes like those of Jim Bob. That rationalization that it’s up to THEM to SAVE us from the Mountain Lion scourge…that attitude certainly plays to their insecurities, and it’s a great excuse for those who just love to go out and kill things.

On the latter point, hunters in general often have a problem with predators like Mountain Lions, for the simple fact that Lions are competition for the same kinds of prey that hunters like to target. As this story from 2010 points out, Mountain Lions likely kill just as many deer in the Black Hills as do hunters. The entire anti-Mountain Lion vibe in that part of the state simply boils down to this basic statement from this story:

Some hunters don’t like the increased competition from lions, said Mike Kintigh, GF&P regional supervisor in Rapid City.

A Mountain Lion kills a deer, that’s one less deer for hunters to kill.  In the minds of “Sportsmen” who think like this, targeting Mountain Lions is a win-win proposition.  It gives hunters the chance to kill a large, challenging animal, while at the same time reducing a major predator of game such as deer and elk.How do you combat some of the “fact-challenged” rhetoric from the anti-Lion crowd in South Dakota?  Facts don’t seem to have any impact on people like this, but as a scientist, it’s quite easy to shoot down the “logic” of these folks with some basic empirical evidence and numbers.

  • ONE — Again…in the entire history of the state, only ONE recorded attack of a Mountain Lion on a human being, and that was an obvious case of just being in the wrong place at the wrong time, surprising a mountain lion on its kill.
  • THREE — In all of Eastern South Dakota in 2013, there were only three confirmed Mountain Lion sightings. No, East River paranoids, Mountain Lions are not in any way a “nuisance” or any kind of threat in the 30,000+ square miles east of the Missouri River. Let’s at least keep the argument just to the Black Hills region.
  • 250 — That’s the roughly the number of Mountain Lions currently thought to be in the Black Hills. In an area of about 5,000 square miles, that puts the number at about one Mountain Lion for every 20 square miles.  That’s a high density for anywhere in North America, much less for such a heavily used area like the Black Hills.  Yet again, despite the number of lions and the potential for interaction with the thousands of visitors and residents in the Black Hills, dangerous encounters have been non-existent.
  • 5,500 — That’s how many deer may be killed every year in the Black Hills by Mountain Lions.
  • 90,000 — Roughly the number of deer killed by hunters every year in South Dakota in the 2000s…during the exact time period when researchers believed Mountain Lion populations were at all-time highs in the Black Hills, with potentially 400 individuals present.
  • 69% — Recent success rate of hunters targeting deer in the Black Hills.  Evidently the Mountain Lions have left one or two deer for human hunters.  No, hunters, Mountain Lions are not wiping out the Black Hills deer population.
  • #5South Dakota was recently ranked as the 5th most likely state for a driver of a vehicle to strike a deer.  One in 70 South Dakota drivers on average have a claim related to a deer collision.  Perhaps a little NATURAL population control would benefit South Dakotans, particularly since the risk of any negative consequence (aka, an attack) is far less than the odds of being struck by lightning.  If only there were some SCIENCE to back this up…hmmmm……
  • 155 — That’s how many lives in the eastern United States would be SAVED over a 30-year period in the eastern United States, IF Mountain Lions were reintroduced into the area.  The number comes from a detailed socioeconomic analysis of the impacts of reintroducing Mountain Lions in the East. The savings come from the reduction in deer populations that would result from the introduction of their most effective natural predator, and the resultant reduction in deer-car collisions.  The same study found that over $2 BILLION in insurance costs would be saved over the 30-year period.

Not to let something as mundane as “science” get in the way of the thinking of people like Jim Bob, but if that many lives and insurance dollars would be SAVED in the eastern U.S. by reintroducing the Mountain Lion, how many avoided collisions in the Black Hills are a result of the presence of Mountain Lions?  How many lives have thus been SAVED by the presence of Mountain Lions in the Black Hills?  If you’re doing a cost-benefit analysis, that would be XX number of lives saved, compared to…ZERO lives that that EVER been lost in the state as a result of a Mountain Lion’s activities. What? That’s all speculative you say?  Not so fast my friends, SCIENCE TO THE RESCUE AGAIN!! From the same socioeconomic analysis:

South Dakota offers a test case example of how effective this solution might be. Cougars have been slowly migrating East: They only recolonized the Black Hills in western South Dakota in 2005. When Gilbert and her team looked at mountain lion recolonization in the western part of South Dakota, they found that from 2005–2012, deer-vehicle collisions fell by 9 percent, resulting in $1.1 million in annual societal benefits for the citizens of western South Dakota. (A 9 percent reduction in seven years is roughly on par with the 22 percent reduction, which researchers think will take 30 years from recolonization.) By avoiding an estimated 158 deer vehicle collisions annually, auto insurers are already saving roughly $630,000 a year in payouts in the Black Hills.

DATA!  REAL DATA showing the decline in deer-auto accidents in South Dakota that occurred RIGHT when Mountain Lion populations were spiking in the region.

If you support Mountain Lion hunting in South Dakota, please spare us all the bullshit.  It’s NOT a safety issue.  Not to let facts spoil your storyline, anti-Mountain Lion, crowd, but from a safety standpoint, there’s absolutely no doubt that South Dakotans are safer WITH Mountain Lions than without.

SCIENCE!! NUMBERS!! FACT!!!

If you’re going to spout off about the need to “control” Mountain Lions, skip the crap about safety.  It’s clearly about either 1) your COMPLETELY irrational fear of a beautiful creature that’s MUCH less likely to harm you than is your hair dryer, shaver, or random bolt of lightning, or 2) your desire to KILL a creature for no other reason than the enjoyment of the “sport”.
