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

Author: DakotaBirder • Discussion: No Comments
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.
  • #5 — South 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”.

6 years, 12 Whooping Cranes Shot by Rednecks

Author: DakotaBirder • Discussion: No Comments
Whooping Crane - Grus americana

A young Whooping Crane in flight. As a young bird, it’s got a rusty wash on its head and spots on the wings, but even so…this is one BIG bird, and there’s really nothing like it. There’s certainly no bird that looks like this that can be legally shot in the U.S. Yet thanks to Homo redneckii, yet another Whooping Crane has fallen to a gunshot, the 12th in just 6 years. Photo from U.S. Fish and Wildlife Service.

I sometimes wonder if the human race is actually comprised of two species. On the one hand, you have Homo sapiens.  I see the wonderful folks around me….family, friends, and co-workers who 1) care about their fellow human beings, 2) care about the world around them, and 3) care about their children’s future.  On the other hand, you have another species, let’s call them “Homo redneckii“.  Homo redneckii have been QUITE active lately (particularly around early November of last year). Homo redneckii have a strong paranoid streak.  Instead of caring for their fellow human beings and participating in societal functions that ensure overall well-being of the species, Homo redneckii are all about…themselves.  Homo redneckii don’t believe in the greater good.  They don’t believe in social structures such as “government’, “law”, or even basic morality.  Homo redneckii don’t give a damn about their fellow man, and rebel against even something as simple as paying taxes to support social programs. Homo redneckii are insecure and jealous, and sneer at the “elite” educated Homo sapiens who have clearly done better at life than themselves.  Instead of working to better themselves, Homo redneckii will instead take the easy route and viciously try to bring others down to their level.  In summary, Homo redneckii believe they can do whatever they want, that the world around them exists simply for their own personal exploitation, and the well-being of future generations means NOTHING if it might require even the tiniest of sacrifices.

As a scientist, as somebody who cares about the environment, and as someone who cares about my son’s future, the activities of Homo redneckii are often hard to swallow. It even often intersects my “safe haven” of birds and birding, the place I usually go to escape the madness of the world around me.  Today was one of those days.  A bit of backstory…

On three occasions I’ve been to the Platte River in Nebraska in March for the amazing Sandhill Crane migration.  Hundreds of thousands of Cranes foraging in corn fields, flying overhead, roosting on sandbars by the evening…it’s an amazing sight, and that doesn’t even account for the many thousands of Snow Geese and other waterfowl that are also typically around at that time.  In all the times I’ve seen Sandhill Cranes in Nebraska and up here in South Dakota, it’s always in the back of your mind that perhaps, just once if you’re lucky, you’ll see a flash of white, and a bird that’s considerably bigger than all of the others.  It’s always in the back of your mind that perhaps you’ll be lucky enough to spot a migrating Whooping Crane.

Alas, I have yet to see a Whooping Crane, other than a captive bird.  There have been a few false alarms, such as the time a couple of years ago when I saw a small flock of Sandhill Cranes flying overhead. It was from a long distance, but just behind the Sandhill Cranes was a very large white bird with dark wing tips.  WHOOPING CRANE!  That’s what first flashed through my mind, until, alas, the birds got closer and it was clearly “just” an American White Pelican.   These kinds of misidentifications are common when out birding, where you’ll initially see a bird and believe it to be a certain species, only to note it’s a different species when you get a better look. What is quite clear though is that if I ever did come across a Whooping Crane, if I was anywhere within a few hundred yards, it would be quite easy to identify.

When you’re birding, and you initially misidentify a bird, it’s obviously no big deal.  When you have a gun in your hand, it IS a big deal.  One of the most accessed pages on my entire website is a page that helps to differentiate between Sharp-tailed Grouse, and Prairie Chickens.  Do a quick google search, and you’ll find out the reason why. There are a number of hunting forums where somebody asks how to tell the difference between the two species, so they don’t accidentally shoot the “wrong” bird.  It’s not just grouse and prairie chickens, it’s also quite obvious that hunters often have a hard time telling apart duck species or other game.  Given that there may be a legal hunting season for one species, but not for another, somewhat similar-looking species, there’s obviously the potential for a trigger-happy hunter to shoot the “wrong” bird.

Evidently, there have been 12 “trigger-happy misidentifications” over the last 6 years, where hunters have shot and killed endangered Whooping Cranes in the U.S. As of 2015, there were only about 400 wild Whooping Cranes in existence.  That’s up considerably from just 21 birds in the 1940s, but they are still obviously an endangered species, and losing ANY bird is a huge loss, much less having 12 shot by “mistake”.  The latest happened just a week ago, when an adult Whooping Crane was shot and killed in southern Indiana.   This bird was an adult female, one who had just laid an egg this summer and had it hatch.  The youngster later died, but the loss of a breeding female who was able to successfully mate and hatch an egg is a huge loss for Whooping Crane conservation efforts.

Let’s dispense with the bullshit though about “misidentification”. Let’s face it…there’s no mistaking a Whooping Crane, not if it’s within range of a shotgun or a rifle.  It’s the tallest bird in all of North America, and it’s a brilliant white bird.  The only other large, white bird with a body shape and structure anything close to a Whooping Crane would potentially be a Great Egret, but 1) even a Great Egret is much, much smaller than a Whooping Crane, 2) Whooping Cranes have obvious black wing tips that would be visible in flight, and 3) IT DOESN’T MATTER if you confuse a Whooping Crane with a Great Egret, because it’s not legal to shoot EITHER species.  I’ve lost count of how many hunter/hunting related “incidents” I’ve come across while out birding in South Dakota, incidents where I’ve personally witnessed (and reported) hunters shooting creatures they shouldn’t be shooting.  I’ve come across plenty of hunters who are anything BUT sportsmen, men (yes…always men) who love their guns, love to shoot things, and don’t seem to care what they shoot.  Given that it’s practically impossible to mistake a Whooping Crane for ANY legally hunted bird, I won’t give any benefit of the doubt to any of the 12 redneck hunters who shot and killed these 12 Whooping Cranes over the last 6 years.

It was a little over 3 years ago where a Whooping Crane was shot right here in South Dakota. Jeff Blachford, a 26-year old man from Miller, South Dakota, was apprehended and charged with the crime.  Blachford was fined a hefty $85,000…a welcome change from past incidents, because other hunters who have shot Whooping Cranes have sometimes escaped ANY sort of penalty. The last time a Whooping Crane was shot in Indiana, prior to this recent event? It was just back in 2009.  The hunter was identified and fined…ONE DOLLAR. Yes, a $1 fine for shooting one of the rarest birds in the world. It remains to be seen what happens in this latest incident.  It appears that it’s still under investigation, and it doesn’t sound like they’ve found the perpetrator yet. Given the outrage after the last Indiana “sportsman” got off so easily, one would hope that the punishment would better fit the crime, should the redneck be identified.

I worry that homo redneckiism is actually a contagious disease. When Blachford shot the Whooping Crane in South Dakota a few years ago, I blogged about it, and was immediately innundated with emails from angry Homo redneckii from the Miller area.  I’m not a religious man, but if I were? I’d pray for the poor folk around Miller, and other locations where Homo redneckiism has manifested. It’s spreading so quickly.  There are some truly nice folk in South Dakota, but as this last election showed, many are also remarkably susceptible to Homo redneckiism.  Hunting rights, paying taxes, (having a black president)…all issues that have proven to be triggers for homo redneckiism.  In the midst of this major national flare-up of the disease, here’s hoping that a vaccine is on the horizon.

Otherwise, massive, brilliantly white, unmistakable birds like the endangered Whooping Crane might not survive.

In the News – Week of January 1st, 2017

Author: DakotaBirder • Discussion: No Comments

A new year, a new set of nature and science news pieces for the week…

Black-tailed Prairie Dog - Cynomys ludovicianus

A “varmint”, a Black-tailed Prairie Dog. I have on several occasions run into “sportsmen” in South Dakota who are lined up at the edge of a prairie dog town, picking them off one by one with rifles. Killing for the sake of killing…and doing twice the intended harm, given the lead that’s ingested by predators when they eat the carcasses.

Ammunition choice in shooting “varmints” — There have been many occasions on my birding trips to the central part of the state where I come across a sight that makes me sick to my stomach.  I’ll drive past a prairie dog town, and see multiple hunters lined up along a fence line, crouched and in a shooting position, picking off prairie dogs for “fun”.  That’s it…there’s no other purpose to it, other than killing for the sake of killing.  The prairie dogs that are killed aren’t used for anything, they’re simply left to rot.  Unfortunately, “sportsmen” who feel this sick need to kill for the sake of killing end up doing even more harm to animal communities.  By leaving the dead bodies, it provides an avenue for predators to consume the dead prairie dogs, and ingest the lead in the ammunition that was used to kill them.  Lead poisoning is a major cause of mortality for many raptor species, and is THE leading cause of California Condor mortality. A simple solution, as this article points out, would be to use ammunition that’s free of lead.  Even that common-sense approach though, one that still allows redneck hunters to kill prairie dogs and other “varmints”, is hated by hunting groups, as they claim that lead alternatives in ammunition don’t perform as well as lead shot and bullets.  Given what I have come across over the years on all my birding excursions, I’ve had a major downturn overall in my attitudes towards hunting…and particularly…hunters.  Stories like this don’t help my perceptions of hunters.

Cheetah numbers down to 7,100 worldwide — Over the last century, cheetah numbers worldwide have dropped from 100,000, to only 7,100 today.  Think about that…in a world with nearly 7 billion human beings, for an iconic, well-known predator such as the cheetah, there are only several thousand left. As with most species’ declines, habitat loss is behind the cheetah’s loss in population.  They range over huge territories, and there simply aren’t “huge territories” available in most parts of their range any more.  Throw in targeted persecution, such as the shooting of cheetahs by poachers and farmers, and this story estimates cheetahs could be extinct in the wild in 20-40 years.

Goldenrod Soldier Beetle

Is this the face of Earth’s largest animal migrations? This is a Goldenrod Soldier Beetle from here in South Dakota, and I admit I have no idea if these “migrate” as with some beetles mentioned in this story. By sheer mass, however, this story points out that insect migration likely dwarfs any other migration on the planet.

Biggest migration of land animals on the planet — When you think of what creature may make up the largest migration of any land animal on the planet, in terms of sheer mass, what species do you think of? Or group of species?  When you say “migration”, most people probably think of birds first, and there certainly are mass migrations of birds that are so heavy that weather radar is being increasingly used as a tool to study those migrations. In terms of sheer mass, perhaps some people think of large caribou migrations.  However, as this study notes, one overlooked migration likely has all of these beat…insect migration.  This study notes that around 3.5 trillion arthropods migrate over southern Great Britain each year, accounting approximately 8 times the mass of bird migrations in the same area.  Some winged insects are well-known for their migratory talents, such as the Monarch Butterfly in North America.  But as this study notes, there all sorts of winged and even non-winged creatures that migrate through the atmosphere.

What the heck is a “species” anyway? — People are funny.  We have this intrinsic need to categorize things, put them in neat little bins that help our minds process realty.  Birders sometimes take that to an extreme, with “life lists” that are often incredibly detailed, with “big day” lists (how many species you see in one day), “big years”, “state lists that detail bird species seen within the confines of state boundaries, and more.  What gets bird listers in a tizzy?  Just what IS a species!  The American Ornithological Union and American Birding Association are always making tweaks to their “official” lists of species that have been found in North America.  Just watch birders heads collectively explode if the AOU or ABA does decide to split Red Crossbills into up to six distinct species…life lists will be substantially increased!!  Even with the science of DNA-based splits, it’s still not a precise science in determining what’s a unique species.  As with many things, we’re categorizing things into unique thematic categories, when the phenomena you’re measuring is actually a continuous variable with no definite boundaries.

One, maybe two new comets moving through — Speaking of birders and their lists, I have a friend at work who is a birder, and someone who has a life list.  He also has another, more unusual life list posted on his bulletin board in his office…his “comet life list”!  He’s about to get one, and maybe two new ones for his list.  Comet C/2106 U1 was recently discovered by the “NEOWISE” project, and is potentially visible with binoculars right now, through about January 14th. It would appear in the southeastern sky just before sunrise.  An object called 2016 WF9 was also discovered by NEOWISE, and it will come close to Earth’s orbit in late February.  It’s estimated to be 0.5 to 1.0 km in diameter.  Note the designation “object”, because it’s not clear whether this object is an asteroid or comet (related to the previous story, in that the categorization of what’s a “comet” and what’s an “asteroid” can be fuzzy).

Bird Dropping Moth - Caterpillar - Ponometia

A caterpillar of Ponometia…the “Bird Dropping Moth”. Should a new species of “shit moth” be discovered, I would suggest it be named after Trump, in the same manner that several creatures have been named after Obama in recent years.

Nine creatures named for President Obama — Over the last few years, no less than 9 different creatures have had scientific names that honor Barack Obama.  Multiple fish, a lizard, bird, etc…all have scientific names such as “Nystalus obamai” (A Western Striated Puffbird, in this case). Once Trump leaves office in 4 years (or in a perfect world, once he’s impeached after a year or so), I wonder what creatures will be named after him?  I have many, many classes of creatures where new discoveries should consider his name. There are the Onychophora phylum of worms known for excreting slime. There are the Annelidas…leaches…which would be a wonder creature to name after him.  There’s a moth called Ponometia, and it’s associated caterpillar, that would be good.  Their common name is the “Bug-dropping Moth”.  Naming him after shit would be a perfect way to “honor” him once he leaves office.

Where you’re most likely to get struck by lightning — We had a very unusual Christmas day in South Dakota.  I believe it was 4 years ago when we were absolutely smothered in snow, getting close to 2 feet on Christmas.  We’ve had Christmas’s where the temperature never got above zero.  And then there was this Christmas where we had…a thunderstorm?  In late December? In South Dakota?  We set a record for most rainfall on Christmas Day, getting over an inch in most areas, and the lightning and thunder was the first time that’s ever occurred here on Christmas (or late December for that matter).  I could go into global warming here, but no, the point is the story in the above link.  Standing outside on Christmas Day in South Dakota normally isn’t a high-risk endeavor, in terms of being struck by lightning.  So where are the most active areas on earth for lightning?  Thanks to a satellite called the Tropical Rainfall Monitoring Mission, we now know.  The winner…a Lake Maracaibo in Venezuela.  Over each one square kilometer in the area, one could expect over 230 lightning strikes per year.  The lake is surrounded by mountains, and nearly every night, cool airflow from the mountains hits the warm waters and air above the lake and produces thunderstorms.

Western Meadowlark - Sturna neglecta

A Western Meadowlark, taken with a temp of -10° near Presho, South Dakota, in the winter of 2003-2004. I have a billion Meadowlark photos, but specifically remember this one because it was so rare to SEE one in the heart of winter. Now? They’re everywhere.

Bird migration changing with climate — As I noted in a previous post, I went birding to the central part of the state last week, and was amazed at how many Western Meadowlarks were around.  15 years ago, it was rare to spot one in winter in that part of the state.  Now…I saw hundreds, all across the region.  Global warming? It’s hard to ignore signs like that.  As this story describes, many birds are changing their migration patterns as the climate changes. Many are arriving on the summer breeding grounds much earlier than they used to.  There are also some species where migrations have become shorter, or perhaps such as the case of the Western Meadowlarks, where they’ve simply stopped moving south for the winter.

China bans ivory trade and purchase — A rare bit of good conservation news.  This last week, China announced that they will ban the sale and trade of ivory by the end of 2017. China was by far the largest market for legally sold ivory, with ivory selling for over $1,000 a kilogram.  The Great Elephant Census recently published noted that elephant populations world-wide plummeted by 30% in just the last 7 years (!!!!!), and incredible population decline for such a short time period.  With the shutting of the largest legal ivory market, it’s hoped that poaching pressures will decline.  However, it’s hard to guess what will happen with ivory trade, and if much of this will simply move to the black market.
