Let this be a warnin' to ya

Lots of days, I did stupid things.

I feel like no blog about wildlife field research would be complete without some injury stories.

I also feel like nearly every time I've gone to work one of these jobs, particularly the ones with more ferocious-type beasts, my mom and dad bite their lips, try to still their quaking hearts, and spend the next few months expecting the phone to ring at any moment with the news that I was eaten by something with sharp teeth.

But in reality, I don't think I have ever been in fear for life or limb because of an animal.

A prelude: when I started the mountain lion job, I remember asking my boss Kevin how dangerous he felt the job was (after all, we were hiking - ALONE - to lion kills). He assured me that the likelihood of my being attacked by a lion was extremely low, provided I took the same reasonable precautions anybody should take when hiking in the woods in Carnivore Country. No, he said, no, you're more likely to be injured by falling down the crazy steep hills that abound along the Front Range. This I made sure to do, at least once. There's really no way to describe the feeling of suddenly losing your feet, finding them above your head the very next second, and then slamming your hips/butt into the rocks, then thanking your lucky stars that you stopped there and didn't continue rolling.

Well, I suppose I have three main stories about being injured in the field. I'm going to go in order of least exciting to most exciting, so skip to number three if you are desperate to be entertained.

1. Don't be a cheapskate. BUY BOOTS. 

My very first field research job was studying woodpeckers in South Dakota in the summer of 2005, in Custer State Park and Wind Cave National Park. I won't go into terribly much detail, but basically what my one coworker and I did was locate woodpecker nests by birdwatching (what a way to make a paycheck, eh?), then returning to each nest twice a week with an extendable camera to check on the eggs/chicks. We would record the number of eggs, the day they hatched, and the day they fledged (and how many made it that far).

Anyway, since this was my first field job, I really had no concept of the importance of proper footwear. And boots are expensive. And I was a poor college student. So I stubbornly refused to buy them, trekking out in the Black Hills with tennis shoes. This worked out well...for about a week.

One particular study area in Custer State Park looked like a Martian landscape, with flat, smooth, overlapping red rocks stacked haphazardly on top of each other, occasionally (and unexpectedly) loose in places, and pocked with rounded holes (aerial photo on the right). Also, since we were studying woodpeckers, and woodpeckers like dead trees, we were continually dodging deadfall with every step, adding to the difficulty. Oh, and they also were a favorite hangout of rattlesnakes. I had several near misses hiking around in that area.

One day, we were searching for a nest located somewhere in this area, and it was turning out to be difficult because the landscape looked pretty much identical everywhere you turned, and a single little pink ribbon marking the correct tree can be incredibly difficult to find. GPS units could only get you so far, but a lot of the time we'd get close and have to turn in circles looking for the spot. I was walking confidently, looking around as I went, trying to keep track of where I was placing my feet, when all of a sudden I just went down.

This was how it looked a week or so later.

I'm not sure exactly what happened; I must have slipped off the edge of one of the rocks, and twisted my ankle very, very badly; it was certainly the worst I've ever hurt my ankle, to this day. Luckily, it was the end of the day, and the end of the week, so I had the entire weekend to nurse it. I never went to see a doctor (PhD students are not typically the sort who want to deal with worker's comp forms, and our supervisor convinced me my ankle would get better on my own). However, in a relatively short amount of time I could walk pretty freely on it again, so I guess I lucked out.

I bought some boots the next day.


2. Don't be lazy. WEAR THE FREAKING BOOTS.

So, now I have boots, and I've always had a pair of boots for every field job ever after. However, I still don't particularly like to wear them when I don't have to, and this usually means I ride around with them in the truck and don't put them on until I need to do some hiking.

My current coworkers especially make fun of me for this. I don't honestly understand how people can wear those tight, hot, sweaty boots all day if they don't need to. I love the quote from "A Far Off Place", one of my favorite books: "Hadn't it been wonderful to recover the freedom of one's own feet after years of imprisonment in boots and shoes?" I suppose it could be a byproduct of my upbringing in the Arizona desert, where the weather really never gets bad enough to warrant closed-toed shoes of any kind. At any given time during my childhood I probably had 5 pairs of sandals/flip-flops, a couple pairs of dressy shoes, and a pair of tennis shoes for gym class. My first pair of boots were the ones I bought in South Dakota (in the above story) - I was 21 years old. I grew up with free feet and now they will never tolerate being confined.

Anyway, I really got into the habit of working in my sandals on the Mexican wolf project, since most of the time we were just driving around, triangulating on the wolves from our trucks, rarely having to do much hiking. I could easily just hop out of the truck in my sandals, take a bearing, hop back in, and speed away to the next site.

In New Mexico, when we couldn't hear a wolf's signal, one of our favorite places to go was the Negrito Lookout Tower. It was no longer manned, so we could climb up to the top and, most of the time, depending

on where the wolf was, the added height was enough for us to hear a signal. However, the road to Negrito was awful. I had a 4x4 truck, but the boulders on either side - and in the middle - of the narrow, steep road were huge, and I feared for my vehicle's undercarriage. Therefore, most of the time I would stop the truck before I reached the worst parts, and just walk up the rest of the road to the tower. Happily, I could do this in my flip flops, because however bad the road was, it was still a road. No problem.

One day, as I was creeping along up toward Negrito, I pulled over to begin the trek, but I was feeling particularly lazy. The road kind of curved around in a big arc (see picture) before finally getting to the tower, but if I just cut straight uphill through the woods, I could get there much faster.

I looked at the woods. It was a nice ponderosa pine forest, nice and open and inviting as they almost always are. Clearly no need for me to put my boots on. So I grabbed my gear and set off in my flip flops.

I hadn't gotten far when an unbelievable pain shot through the ball of my foot.

I had stepped on something that went right through my shoe and deep through the skin. I searched and searched on the ground around me and couldn't find anything that looked like it could be the culprit. But man, I was out for the count. The pain was even worse than spraining my ankle. There was hardly any blood, hardly even a puncture in my puny flip flop, but something had definitely done some damage.

I debated telling my boss. He didn't like me as it was, and, of course, there was the dreaded paperwork. I suffered in silence for a few days and then finally told him what happened. He frowned at me and told me what an idiot I was (because it was true), but he did say I could go to Show Low to get it looked at if I wanted to. But my stubbornness kicked in. He already hated me, and I would not give him reason to hate me more. Stupid. Yes.

Whatever happened - whether I actually fractured a bone in the bottom of my foot, or just got a really bad stone bruise - it took ages for it to heal. Months later, when I was in grad school, it would still ache occasionally.

I'd like to say I learned my lesson, but I suppose it's debatable. I still drive around with my boots in the truck, wearing my flip flops. However, I certainly put the boots on now whenever I go hike, even for just a short distance.

3. Bear spray. It works (on humans, at least).

This is one of my favorite stories to tell because a) there's a good lesson in it, b) people like to laugh at other people's pain, and c) for once, this time the injury wasn't entirely my fault.

Back to the mountain lion project, 2010...

bear spray

Whenever I went out hiking by myself, I typically carried a canister of bear spray in case I came face-to-face with a scavenging black bear at an old mountain lion kill, or a mountain lion itself. (We also carried bear spray all the time, even when hiking in groups, in Yellowstone because of the number of grizzlies there. I highly recommend doing this, and would not even consider hiking alone in Yellowstone, Glacier, or any other part of Bear Country without bear spray.) Bear spray is basically the same stuff in the typical can of mace on your keychain, just more of it, and stronger. I believe it has been proven very effective on bears, but nobody really knew what it would do to mountain lions. Still, I was too lazy to get my Concealed Carry license, and too cheap to buy a gun, so the free bear spray the Division of Wildlife let me use was going to have to do.

I usually had two backpacks with me every day, a small one just big enough for a bottle of water, some data sheets, and my Spot Unit (an emergency location device), and a bigger one that I put all my daily junk in and used whenever I had to go a greater distance and carry more food and water. As I said, I usually carried the bear spray whenever I was out alone. However, I sometimes didn't take it when I was doing shorter hikes, only a half mile or so away from the truck, because it didn't fit well in my small backpack. Also, when I was with another coworker, I wouldn't bother with it, since the odds were greater that an animal would hear us coming and leave, or be more hesitant to attack. Thus, much of the time my canister of bear spray got left in the truck.

One day, my coworker Kirstie and I were going to check out some data points in a canyon on some Open Space (public) land, just off of Flagstaff Road above Boulder. The road was too
rough for the truck, but we had brought along our ATV. We unloaded it and sped off down the road. I only took a small bag with my water and some other supplies, leaving my larger backpack - and can of bear spray - in the backseat of the truck. We collected the data, turned around, and came back to the truck within the span of about an hour.

When we got back, we loaded up the ATV, and then Kirstie and I prepared to head back to Fort Collins. I opened the little side-door behind the driver's seat, threw my little backpack on top of my bigger backpack, and instantly got a face-full of mace.

Evidently the safety had come off the canister. And the nozzle was pointed directly at me. When my little backpack hit it, it fired off a pretty good dose, directly into my right eye.

Nothing can describe the agony. You'd have to experience it yourself to know how it feels. I doubled over and clasped my hands to my face. Kirstie instantly knew what happened; she had been standing on the other side of the truck, putting things in the passenger seat, in the fresh air, away from the direction of the spray, and yet the instant it went off, she started coughing. That stuff is potent. She rushed over to me and handed me a Camelbak, and I lifted my head and rinsed my eye as best I could.

I was probably spared some pain by my contact lens absorbing some of the blast. I peeled it off and threw it on the dirt. After a couple of minutes, the pain in my eye subsided somewhat, and Kirstie and I decided to get back to Fort Collins as soon as possible. On the drive, I called the Poison Control Center to see if I needed medical attention. Luckily, they assured me I didn't; the stuff was just intended to be an irritant, not to cause serious chemical burns.

The stinging in my eye didn't last very long...but wasn't the only effect. It got all over my skin, too, on my face and some on my right arm. For days, I felt like I had gotten a horrible sunburn, my skin hot and tender to the touch. And my poor truck... for about a week afterward nobody could get into it without coughing, until the residue finally went away.

So, if you ever doubt the usefulness of bear spray, I can assure you that it works. I can't imagine any bear - or mountain lion - getting sprayed with that stuff and not being completely discombobulated, at least for a few minutes; enough time, anyway, for you to get away. And if you don't have any other weapon, it's certainly a great thing to have.

But the main lesson of the story: when not in use, always make sure the safety's on.

I have a canister of my own bear spray now, and you can bet I'm extremely careful with it.

(In recommending bear spray, I feel the need to emphasize that anyone who uses it needs to be aware of several things: they do expire and they do need to be tested periodically.)

Babe

Meet Babe.

I did not take these pictures. Back in 2007, pretty much anyone who came to Upper Newport Bay in Orange County, CA, could see and photograph Babe whenever they felt like it. She was extremely visible, often parading her newest litter of kittens out in front of joggers and motorists in the middle of the day, not at all afraid of the crowds of humans who visited the popular area.

Unfortunately, I don't have any pictures of Babe's kittens, and it appears the ocphotosite.com website no longer exists. As of 2010, she was apparently still alive (Click here for a little news story and photo.). But when I worked with her, it was back in 2007-2008.

I worked for the US Geological Survey for about a year studying the movement of bobcats and coyotes through urban corridors. It was a really interesting study. We drove around Newport Beach, Irvine, Tustin, Laguna Beach, Laguna Woods, Costa Mesa, Lake Forest, and Aliso Viejo monitoring the cats with telemetry, regularly checking a few dozen remote cameras we had set throughout the area, and trying to get more collars out on the animals. The main purpose of the study was to learn more about what the animals needed in a corridor, so that when the Orange County Great Park, which was in the process of being built on the old El Toro Marine Base, was completed, it could facilitate the movement of individuals between the Cleveland National Forest in the east and the San Joaquin Hills along the coast. (Interesting note: Will Smith's character was based out of the El Toro Marine Base in the movie Independence Day.)

Babe was already a pretty well-known cat before she was captured, which happened a few weeks before I got on the project. The capture crew had initially wanted to call her Tamale*, because she began to overheat while they were working her up. This happens occasionally, and they doused her with water and put alcohol on her ears to help her cool off. Eventually, though, they decided to call her Babe, after her habit of cruising Upper Newport Bay.

Unlike the collars we used on the mountain lions in Colorado, the bobcats had GPS collars that collected data points every few hours but could NOT be remotely downloaded. The data was stored on the collar, and when the collar's battery got low, it was programmed to automatically drop off the animal, and emit a different signal to let us know. Then we could walk in and retrieve the collar, plug it in, and get all the GPS data off of it.

Unfortunately, many of our collars failed. Often the drop-off mechanism would fail, the battery would die, and we would lose all ability to find the bobcat, relying then on spotting the cats on remote cameras and trying to recapture them to manually remove the collars. Thus, whenever we detected the drop-off signal, we weren't always 100% sure that the collar was actually no longer on the animal.

One day, Babe's collar started emitting that drop-off signal. Upper Newport Bay itself is a nature preserve, but it is surrounded by very densely populated neighborhoods and a handful of ritzy golf courses. Now Babe had been on her own for a while, having booted off her last litter of kittens, and had kind of disappeared out of her normal area for the previous few weeks. We actually feared she had gotten killed on the road somewhere. When Robert finally did pick up her signal, it was a few miles away from UNB in the heart of one of the neighborhoods. A day or so later, it started to give the drop-off signal.

So Robert set off to find it, eventually pinpointing it in someone's backyard. Robert knew there was the possibility that Babe was still wearing it, so he gave her a few days before walking in to retrieve it. When he returned, the signal was still there, so he got permission from the homeowner and walked into the backyard to get it. The backyard was small, lined by a row of hedges planted in a raised bed that backed up against the stone fence behind it. Robert crawled back behind the stickly, poky hedge with difficulty, came around a corner, and came face to face with Babe herself. 

She didn't act aggressive at all, but Robert immediately got out of there and told us the news. We easily figured she had had her kittens back there. It was quite a protected spot, out of reach of any coyotes or other bobcats that could kill her kittens, and sheltered from the elements. Our best guess was that the collar just happened to drop off there shortly after she gave birth, and her kittens were probably snuggling with it. We decided to give her a few weeks to get out of the area before trying to get the collar. Now, of course, we had absolutely no way of knowing where she was at any given time. 

And so, when the few weeks were up, they sent me in to try to get the collar. 

Robert and one of our supervisors, Lisa, came along. This time it was my turn to poke my head through the hedge. I dove in at the corner and cruised against the stone wall where the foliage was thinnest. When I reached the spot, I stared hard, trying to see through the darkness of the thick greenery. At first, I thought I could see a divot in the dirt, and eagerly moved closer to try to find the collar. But as my eyes adjusted, the dark form in front of me changed, morphed, took a different shape, until I could perceive the barely visible twinkle of a cat's eye against a dark bobcat-shaped head, tufted ears and all. She was still there. 

Again, she didn't react. I could have gotten a face-full of bobcat claws, since I was probably only about five or six feet away from her. I think she understood by now, after her years of frequenting the Bay, that we humans weren't likely to hurt her or her kittens, and bobcats, unlike canids, typically crouch and take cover when threatened rather than run for it. But needless to say, I got the heck out of there. 

 Eventually we were able to retrieve the collar, and Babe came back to Upper Newport Bay with a new set of kittens trailing behind her. She no longer had her necklace, just colorful earrings that she would have for the rest of her life. 

I don't actually know where Babe is now, if she's still alive, what happened to her, etc. Odds are, she got hit by a car, because that seems to be the fate of pretty much every urban bobcat in southern California. But she was one of our greatest tools in educating the southern California public about carnivores, letting them see the untamed beauty first-hand, and teaching them that bobcats can live alongside humans peacefully with no need for fear, as long as we maintain the appropriate distance and respect.

Regarding the bigger project, we ended up getting some interesting data from our cats. We found that in the more densely human-populated areas, somewhat removed from big expanses of habitat like Upper Newport Bay, the Laguna Coast Wilderness, and Crystal Cove, the bobcats were using whatever they could find to move around and build their territory. Two of our cats, named Homer and Sloane (both cats I got to help capture - Homer was my first), were caught right at the junction of the I-5 and I-405 freeways behind a Carmax Superstore. Both had almost completely linear home ranges along the riparian strip that wove between office complexes and neighborhoods. I don't know the status of the Orange County Great Park project, but I hope it's able to connect the east and west habitats, allowing more gene flow among the bobcats to help them maintain their populations in Orange County....because in this world of increasing distance between Man and Nature, the bobcats were the perfect ambassadors.

P.S. If you're interested in that kind of thing, you can find the final report of our project at the following link: Click here! Toward the end, in the appendices, are a bunch of really cool camera-trap photos, including some taken when a wildfire swept over our Cuddeback cameras without damaging them.

*Now that I have spent four months in Mexico, I feel the need to emphasize that the singular of "tamales" should be "tamal", not "tamale". That bugged our Spanish teachers to no end while we were in language class.

In the Lion's Den

One day, I found some mountain lion kittens.

By far, my favorite moments working in the field of wildlife biology have been, and will always be, when I get to see wildlife out doing its thing. When one works primarily with carnivores, this is not a frequent occurrence.

During my time on the mountain lion job in Colorado, I was lucky enough to get a few glimpses of some of our collared cats, as well as an older kitten when I accidentally stumbled upon it (see the post "Here, Kitty"). But what I really wanted was to see kittens in a den. My boss and a tech who was only working part-time for us - which only added insult to injury - had found a den earlier in the season, and I had searched a few likely spots since then but come up empty. 

We usually only checked the den sites to confirm whether or not one of our female cats had had kittens. We weren't cleared to handle them at all - you need special permission from Animal Care and Use committees to do that, apparently. We also had very narrow windows during which to search, as we had to wait until Mama was off hunting, since the last thing we wanted was to stumble upon a very defensive mother mountain lion. The few times I did den searches, we either missed the kittens, or the mother had already moved them. 

I say "miss the kittens" because if you've ever seen a mountain lion den site, you'll understand why it can be so hard to find them. Of the four I had seen, two were located in extremely dense scrub oak thickets, and the other two were in boulder fields. Scrub oak is a species of oak that is short, tough as nails, and grows really close together in enormous groups. You basically have to crawl on your hands and knees underneath the snagging branches to get through it, twisting through it like a labyrinth. Scrub oak destroyed my favorite pair of field pants, for which I have not yet forgiven it. The boulder fields are almost equally annoying, as you have to hop from rock to rock, checking for protected spaces underneath them where a mother might stash kittens, all the while trying not to slip and fall and break your neck. 

As I've said in previous posts, we had GPS locations for all of our cats from their collars, taken every four hours and remotely downloaded; so den sites were usually easy to spot on the maps as an enormous jumble of GPS locations all concentrated in the same general area. But satellite fixes, at least with our technology, are not 100% accurate - depending on the location of the satellites, the position of the cat, the weather, the vegetation, etc., a cat can stay in the same spot for hours and we'll get a map of points sprawled out over maybe a fifty-square-foot area. The kittens could be anywhere in there.

Skunk kill from this cat

And now, I'd like to introduce another star cat, one of my favorites because of her interesting eating habits. She was apparently quite old, and the last time she'd been captured the crew had noticed that her canines were worn almost to stubs. She had had multiple litters of kittens but, to the knowledge of the team, none had ever survived - for some reason, she always abandoned her kittens shortly after giving birth to them. But the most interesting thing about her was the most common prey item I logged for her: skunks. Her data was always easy to collect because I just had to follow my nose, and more often than not it would lead me to a pile of black-and-white hair and little bones, with the occasional intact head or tail sitting amidst it all. Whether her inability to raise young, broken teeth, and taste for skunks were all tied in somehow, maybe to a brain injury or other deformity this cat had, we could never be certain. 

It became clear late in the winter that something was going on - whether she was injured or had kittens, we weren't sure. All we knew was that she was sticking around a particular area for a long, long time. It seemed an odd time for her to have had kittens, but then again Colorado lions don't seem to stick to a regular breeding schedule - they can have their kittens year-round. 

And so, one day, I was instructed to go with another technician to investigate. 

At first, it was an easy hike. The other tech and I - an older, seasoned guy who had worked with lions for decades - drove as far as we could over a rough two-track road, then walked the rest of the way, along a creek and around a gently-rising hill. It didn't take long, however, before the trail ended at a massive boulder field. Below, we could see enormous rocks littering the hillside, the area devoid of almost all vegetation except for a tiny oasis of scrubby trees and shrubs in the very middle of it. We had to backtrack and hike over some pretty sketchy stuff to get down into it. We clambered over the boulders as best we could, and all the while I checked the mother lion's telemetry to make sure she wasn't in the area; we were able to hear her signal, but it was very weak, clearly indicating that she was far across the valley below.

It took a long time but we finally reached the trees in the middle. We were in the middle of the big jumble of GPS points, most of which were concentrated, of course, around the boulder field. I balked at the task before us; it was going to take ages to search under the rocks. I briefly considered giving up. After all, the kittens were probably gone or dead, and I had learned from experience that trying to find these guys in this kind of situation was like - pardon the cliche - trying to find a needle in a haystack.

However, Nature itself, this time, came to my aid.

From startlingly nearby, I heard a shrill whistle. It sounded completely out of place in this barren, silent landscape. I thought maybe my coworker had made the noise, but when I looked at him, his eyes had gone wide. "Kittens!" he said.

"What?" I said. Surely mountain lion kittens didn't whistle.

But the whistling continued, and as I was closer, I scrambled over the enormous boulders, trying to pinpoint the source of the sound. When I stood atop a particularly gigantic rock, looking down at a little patch of soil separating it from its neighboring rocks, a slight movement caught my eye.

A mountain lion kitten, days old, crawled out from under the boulder, its ears and eyes still shut, its fur speckled with little black spots. In between its whistles, we could hear the whistling of a sibling, still concealed beneath the rock. The visible kitten groped blindly in the dirt for just a few seconds before heading back toward the safety of the den.

I couldn't believe my luck. I had finally seen a mountain lion kitten.

Click on the video below from the Cincinnati Zoo for some examples of the sound.

The whistling is the kittens' method of communicating with their mother, and I heard it later, from the Golden lion's kitten ("The Cat Came Back - Part II"). It's certainly not the sound you would expect to come from a cat. I was glad the little kittens had done it, though, or we probably never would have found them.

Unfortunately, the crazy mother did abandon them, as her behavior over the next few weeks didn't indicate she was still supporting kittens. And so, a little while later, I brought my boss Kevin to the site to see if we could find them.

We made the difficult journey back to the site, and I lowered myself down into the space between the boulders to dig around in the dirt. It didn't take long for me to find little bones and poofs of spotted kitten fur. Kevin even got down and crawled as deep into the den as he could go, which was pretty deep (see pictures).

See if you can find his shoes

So, it was kind of a sad story, as the kittens didn't make it; but these things happen, and I'm not sure I would have felt better if we had had ACUC permission to rescue the kittens and bring them back to Fort Collins. There, they would have grown up in a pen (if they survived at all), then probably been translocated out in the woods again to fend for themselves. Some lions can thrive in those circumstances, it's true. At the risk of sounding like a hypocrite, since I love seeing wildlife up close and getting the chance to touch and smell and hear the animals while processing them at capture, it's always best to interfere with these animals' lives as little as possible.

Nature can be harsh, yes. Mothers abandon their young for reasons we don't understand. Animals take the lives of other animals to survive. Even though I love carnivores, and I myself eat meat occasionally, whenever I'm watching a documentary of a wolf or a pride of lions chasing down its prey, I find myself rooting for the chased, the underdog, the victim. We find ourselves empathizing with creatures, allotting human rights and qualities to them, finding sadness in tragedies such as these. Some people think it's in our nature as humans to fear the wilderness and all its ferocity, its untamedness, its danger, to want to distance ourselves from this life-and-death struggle that goes on outside our cities.

But is our fear of wilderness in our nature? Or do we fear it because we have lost our nature?
