Mountain Lion sighting near Sioux Falls, and “protecting” people from imagined dangers

Mountain Lion - Puma concolor

We arrived back from our vacation in the U.S. Virgin Islands on Monday.  It seems that while we were gone, there was a bit of excitement in the neighborhood!  While talking to a neighbor, he told me about a neighbor across the street who was QUITE surprised to see a Mountain Lion lounging in a tree in his back yard!  We live in extreme eastern South Dakota, only a few miles from both Minnesota and Iowa.  South Dakota DOES have a healthy Mountain Lion population in the Black Hills, where biologists typically estimate that a few hundred are around.  Black Hills Mountain Lions are known to wander widely, with tagged animals found far from the Black Hills and far from South Dakota.

However, in our part of the state near Sioux Falls, the landscape is dominated by corn and soybeans.  There are certainly plenty of deer around that would interest a mountain lion, but there isn’t a lot of natural habitat around.  The only forested areas in the area are typically riparian zones.  The potential attraction for the mountain lion seen in our neighborhood?  We live across the street from the Big Sioux Recreation Area, a state park along the Big Sioux River that features a lot of burr oak, cottonwood, and other trees along the river.  Turkeys and deer both abound in the park, but it’s a small oasis of habitat sitting in a vast landscape of cropland.  It’s also not all that large a park, covering a thin strip along the river for less than 2 miles.  From a long-term habitat standpoint, it’s simply not a location that’s going to hold a population of Mountain Lions for any sustained length of time.

The park is quite popular with campers, joggers, bikers, hikers, dog walkers, etc.  There’s a very nice paved path through the park that connects with other paths in the city of Brandon itself.  There are also other unpaved paths that people frequently use.  The number of people using the park also make it quite unlikely that any Mountain Lion would attempt to stay for any prolonged period of time. The number of people using the park ALSO will likely be used as a reason for Game Fish & Parks to “remove” the Mountain Lion should it happen to stick around.

There has NEVER been a recorded case of a Mountain Lion attacking a human being in South Dakota.  NEVER.  Despite that, they are treated as an extreme danger.  The story linked to here is the typical reaction when any Mountain Lion is found anywhere close to humans in the state.  The Mountain Lion is killed, period.  In the story I linked to, the lions were near Keystone,.  Keystone is in the heart of the Black Hills, and thus, the heart of Mountain Lion country in South Dakota.  The lions were clearly within their normal habitat, but were still “removed” (killed).

Mountain Lions are quite common in the Black Hills, but are rarely every seen.  Being shy and staying away from people is certainly a positive for a Mountain Lion in the state, as just being SEEN is an offense punishable by death for a Mountain Lion in South Dakota.  The Keystone story above has been repeated many, many times in the state, with Lions being shot and killed whenever they happen to be found near people.  That’s especially true outside of the Black Hills.  In South Dakota it’s such a rare sight to see a Mountain Lion outside of the Black Hills.  If one IS seen, people immediately freak out and assume it’s a danger, despite, again, the fact that there has NEVER been an instance of a Mountain Lion causing harm to a human being in the state.  While birding in the Yankton area several years ago, I heard a blood-curdling “scream” in a forested area along the Missouri River, a sound I know came from a Mountain Lion.  I certainly never reported it, knowing what would happen to the animal if authorities were alerted to its presence.

I haven’t heard neighbors say whether the mountain lion found here has been seen again.  Frankly, I hope it has moved on and WON’T ever be seen again, just from the standpoint of the animal’s own safety and well-being.  A “seen” Mountain Lion in South Dakota is usually a CONDEMNED Mountain Lion.

The tale of “Swabby” and “Captain”

Pearly-eyed Thrasher - Margarops fuscatus

“Captain”, the bold “leader” of the local clan of Pearly-eyed Thrashers hanging out around our vacation beach house at St. John’s in the Virgin Islands.

Back from the Virgin Islands!  The family vacation for the summer was on the island of St. John’s in the U.S. Virgin Islands.  We had a rental house right on the water and had a wonderful time.  Our own little private cove and beach, wonderful snorkeling right outside the door, and great food. Of course, there was also a wee bit of birding involved!  I’d never been to the Caribbean, and although the relatively small island of St. John’s doesn’t have a huge variety of bird species, there were some nice “lifers” I was able to see and photograph.

One of those species is the Pearly Eyed Thrasher.  They are a very common and very visible species in the area, but given their geographic range, they were obviously a “new” species for me.  It didn’t take long after we arrived for us to see our first Pearly Eyed Thrasher!  We flew into St. Thomas and took the ferry over to St. John’s, then driving across the island towards Coral Bay and the location of our beach house.  The owner met us and as we were being shown the features of the house, we were greeted by “Captain” (the name my son immediately gave him!), an extremely tame Pearly eyed Thrasher who the owner said “owned” the beach house! Captain certainly did act as if he owned the place!  Every time we were on the deck overlooking the ocean, Captain was there, either casually searching for food, or just hanging out on a nearby tree or the deck itself.  Captain was certainly curious, often choosing to sit and perch within just a few feet of where we were lounging.

Captain was usually accompanied by “Swabby” (again, the name my son gave him!).  “Swabby” was a bit more shy than Captain, and usually was only around if Captain was around.  Swabby generally hung out a little further away from us than Captain, but he too was often very close to us.

I knew before we arrived that they were a common species, with one local birder telling me that locals in the Virgin Islands think of Pearly eyed Thrashers in much the same way as we would think of House Sparrows or Common Grackles here.  One of the joys of birding, however, is seeing a “new” species.  No matter how common a Pearly eyed Thrasher is in the Virgin Islands, they were new to us and were a real joy to have around, particularly as they were so tame and entertaining.  Clearly Captain and Swabby were accustomed to guests at the beach house.  The owner warned us not to leave any small items out on the deck, as they would be “confiscated” by Captain and Swabby!  That certainly was the case for food items too, as Captain and Swabby could be quite bold in begging for food.  We refrained from giving them “human food”, but after noticing their love of the petals of a certain flower, we did gather a few on occasion and put them out for Captain and Swabby to enjoy.

“Swabby”, the day after an accident or attack left him with an obviously broken leg. Despite the horrible looking injury, Swabby seemed to quickly adapt to his new situation.

3 days after arriving, it was obvious that Swabby had been attacked or had some serious accident.  One of his legs was clearly broken and/or dislocated.  The leg was useless to Swabby, held at an awful-looking angle.  For the first couple of days after the leg was broken, Swabby struggled. He wasn’t around as much, and when he did come near the deck, he struggled to adapt to his new situation.  He didn’t seem to have enough strength in the one remaining leg to hold up his body, so whenever he landed somewhere, he typically would lay on his belly.  We gathered a few more flowers for Swabby, and thankfully he was still feeding normally. After a couple of days, the leg still was useless and was still held at a horrible angle, but Swabby seemed to be gaining strength in his remaining leg.  He was starting to hop around on one leg, and seemed to be able to hold his body up with the one leg.

Of course we’ll never know what happened to Swabby, but there are a couple of “unnatural” predators on the island that could have been the culprit.  Mongoose were introduced to the islands many decades ago, a misguided attempt to control runaway rat populations (another introduced species).  Mongoose have had a devastating impact on the native wildlife of the Virgin Islands, particularly on ground-nesting birds.  Another potential culprit is another introduced species, the iguana.  We ran across some extremely large iguanas during our trip, including one gorgeous, bright green iguana in a tree right outside the beach house.  My guess is that either a mongoose or an iguana managed to get a hold of Swabby’s leg, and Swabby only escaped after breaking free of whatever predator attacked him.

As we left the Beach House to start the long trek back home, Captain and Swabby of course were present to give us a proper send off!  We did put out a bit of left-over bread as we left, which Captain and Swabby immediately devoured.  “Common” or not in the Virgin Islands, it was a treat to see a new species.  Birders tend to get enamored with adding new species to their life lists, and often forget to appreciate the birds that are commonly seen.  Watching their behavior at such close range, interacting with them in the way we did, was a reminder to appreciate the “common” species we have back here in South Dakota.
