Chasing rays and calling jays in Aransas!

Well I was lucky enough to get to tag along on this years Ornithology class trip to the Aransas National Wildlife Refuge! By lucky I mean Ray needed another driver and I happened to fit the bill. Nevertheless! It was a fantastic trip full of random adventures, joyous laughter with fellow wildlifers as well as lots and lots (and lots!) of birdwatching. There is no way to describe all of the memories as it would take a novel to hold them all so I will provide you with some of the highlights and hope that that will temper your appetite for awesomeness!

We left bright and early Thursday morning (Feb. 28, 2013) and established the caravan pecking order straightway. Ray took the lead as our fearless leader and navigator while Jarret the Teaching Assistant was kind enough to haul most of the equipment and students. I brought up the rear with my delightfully unruly, entirely female charges plus one Canadian. We aptly named our crew and vehicle "The Juicy Caboose" and referred to it by name all weekend, garnering many laughs and maybe an eye-roll or two. We got into Aransas at about 7:00 pm that night and promptly scouted out our accommodations for the weekend, the YETA. It's a lovely screened-in shelter with a cement floor and plenty of picnic tables. The area overlooks San Antonio Bay and is quite sandy as well as shaded by sea-breeze-twisted old gnarly oaks. After an inevitable scrambling territorial display to claim picnic tables and sleeping spaces we settled down to a hasty dinner of sandwiches, chips and Gatorade. We then jumped into the vehicles again (as if we hadn't had enough driving during the previous 12+ hours) and headed out for spotlighting and road cruising. We stopped at Hog Lake and spotlighted for  American alligators - I can't tell you how excited we were to see and possibly catch one! We spotted quite a few and tramped through the marsh for a closer look but they were in too deep of water. I was a short distance from the group watching a mammal on the far bank that appeared to be a raccoon. I slogged closer to get a better look, thanking my lucky stars that I had worn my "duck boots" and was not already getting my footgear wet as so many of the other students were forced to do. While stalking the raccoon I saw more eye-shine and a green lump. I assumed it was a frog and kept going. Well, lo and behold, I quickly saw that my "frog" was an alligator snout pointed right at me and just begging to be caught! I turned and yelled to the others, "I got one!! It's a little guy, we can get 'em!!" There was a brief moment of stunned silence broken only by Ray muttering, "Oh here we go" before a veritable SEA of headlights came sprinting at me; Matlack in the lead! He and Jarret positioned themselves on either side and showed us the proper technique to safely catch and restrain an alligator. Turns out my "little guy" was 5-6ft long so there was some ridicule of course. I'm stickin' to my guns though, that's a little one!! I want to catch a 10-footer!! Jarret then showed us a safe release and we left the gator to his business while we tramped off to search for more of his brethren and any other wildlife. We did a few more laps of the loop and spotted feral hogs, raccoons, cottontails and an opossum before we called it a night. All I will say about that night was it was COLD and that despite my warm clothes and sleeping bag I wished for death more than once!

The next morning we were up and birding along the bay. There were plenty of Brown and American White Pelicans, Laughing Gulls, Great Blue Herons and Northern Cardinals. We went to several areas in the park including the Tower to look for Whooping Cranes, the refuge's most famous species but fortune did not favor us that day. That afternoon we assembled a "shore party" as I called it for a supply run to Wal-Mart. I was not the only one unprepared for cold nights! On the way out we spotted two Crested Caracaras perched in a tree as well as many Black and Turkey Vultures. That night, James decided to brave the sea of estrogen and drive the Caboose when we set out to spotlight. We stopped at several alligator ponds and called them in with baby alligator distress calls which did not fool them for a second. When the coyotes cranked up for their nightly performance Jen and I stood on the bank and howled along with them. I took over driving so that James could jump out to catch anything that presented itself. Things were going along fine until I noticed a small mammal running in front of Jarret driving the front van. I couldn't tell what it was but I was shocked that they were driving and not trying to catch it. In hindsight, maybe that should have been a clue. All I could see was a bouncy black thing running and I yelped, "It's running like a weasel!" That was all it took for James to bellow, "Stop - I'm getting out!!" He did and took off running next to the lead van. Thinking the others meant to follow him I yelled "GO! GO! GO!" very much in a drill sergeant manner, as I am known to do. The poor girls piled out of the van and followed James who was bearing down on a....skunk. It was a skunk. Not a weasel. Well, who knew?! Actually, the front van did which is why they were safely driving along and not dashing through the darkness like my crew. After much deliberation we decided that we could never admit that it was just a skunk and that it must have in fact been a new species, called a "Skweasel" and the sound it makes is "GO GO GO!!!"

 The next day, Saturday, we left the refuge to explore Goose Island State Park, Rockport, Aransas Pass and Port Aransas. On the way out we spotted a fresh feral hog carcass with a large crowd of vultures and a bobcat walking along a trail. You can imagine the shrieking and high-fives following the sighting of that cat!! All right, most of it was me....but the others were excited too! After Goose Island we saw "the Big Tree" which is approximately 1,000 years old and very impressive. We also got a very, very far away look at some flying Whooping Cranes. Luckily, someone informed us that there were others much closer and so we jumped into the vans, drove about 6 blocks and pulled over next to a backyard where four of them were foraging. We set up spotting scopes and filled our eyes with the graceful, highly endangered cranes. We then took the ferry across to Port Aransas and walked out on the jetty. It was incredibly beautiful with the aquamarine water, bracing wind and dignified pelicans waddling about. We watched porpoises dive among cormorants and sea turtles surface in the waves. After more birding at a few more places we had dinner at a local seafood restaurant and drove home.

The next day was a very relaxed, explore-the-refuge day and much warmer. We walked down to the beach and waded in the cold, clear water. After awhile your feet became numb and then it was quite pleasant! I joined Jarret and James as they shuffled along looking for stingrays. Jarret scared up a cownose ray and the chase was on! We were dashing through the water trying to get close enough for a picture and succeeding only in drenching ourselves. Soon a few more students joined us and we formed a ray-interception line. We decided we simply had to catch one and made various plans and stratagems to achieve this. Every few minutes we'd spot one and it was a mad dash to surround it and herd it into our circle. Every time it would bump or touch us we'd invariably yell, flail and splash wildly in our attempt to ray-wrangle. I cannot tell you how much fun we were having on that beautiful beach with the incredible turquoise water, flawless sand, tolerant rays and uproarious laughter at ourselves. It should come as no surprise that we were not successful despite our many attempts and Jarret's diving headfirst after two of the rays. He is a track and field coach at WT and became famous in our group for charging through the knee-deep water with us laughing and screaming, "Knees to chest!! Commit! COMMIT!!" as we kept up as best we could (which was not very well, that guy is fast)! After what had to be hours we were exhausted and headed back to the YETA to change and eat. A few of us decided on a whim to drive to a likely spot down the road and try to call in some Green Jays, which only one or two of us had seen before. That quickly became a full mobilization of the troops with everyone packing into one van as best they could. We were unsuccessful with the jays and only managed to attract some chatty cardinals. Some of the students went to go look for American Bitterns, a bird species on everyone's hope-to-see list. After awhile, the Caboose packed up and decided to get started road-cruising. We were hoping we'd get a lot more reptile and amphibian activity since the day had been so much warmer but we were out of luck. We stopped in at another alligator pond and practiced our distress calls to the delight of a passing gaggle of senior citizens. Once it was dark we began spotlighting and using the night-vision monocular, one of my favorite toys. While we were watching a large alligator watch us, one of the girls said they saw an animal moving right towards us. It was a nine-banded armadillo. The desire to catch an armadillo on this trip was second only to catching an alligator so you can imagine the instant uproar. Unfortunately the armadillo was on the alligator's side of the fence. Jen and I looked at each other and in that split-second we both knew what the other was thinking, "Who's going over? You or me?" The 'dillo, no doubt sensing our nefarious plans headed straight for the gators! We stayed on our side and bided our time, hoping it would round the fence and therefore be fair game. It did and the race was on! Jen leaped after it, flashlight clamped between her teeth while I held the so-expensive-if-you-break-it-you-are-dead monocular and bellowed orders. Some girls ran to get lights, some ran to help Jen and some tried to keep an eye on the water and the alligator that had been watching us! Unfortunately, by the time we were better organized the armadillo had gotten into a thicket and there was no going in after it, especially that close to the water's edge! Dismayed, we shuffled away with many a backward-glance and consolations for one another.

The next morning (Monday, March 4th) we packed up early and hit the road. We saw more caracaras and a bald eagle on the way up and had unending conversations, laughter and reliving of our adventures. No one could stop talking about how much fun we'd had and the wonderful things we got to see. Plans were made for Skweasel t-shirts and a massive email swap of all pictures as soon as possible.

And that, dear readers, is really just another day in the life of a wildlifer!

P.S. Cownose rays are venomous, we discovered this once we got home. Oops!!

Sunrises and Skunks!

I went out to my study site last weekend with an undergraduate Research Assistant, James Skaggs, to check bobcat traps and just be back in the field for awhile. One of my main joys in life is to start the day before dawn, dressed in my field gear and snake boots and head out of town with the sun just starting to color the sky and the radio turned up! While driving north along US-87 I couldn't help but gawk at the beauty of the day. I had the high misty moon on my left and a beautiful pink and gold sunrise sweeping across the sky on my right. We complain about not having trees on the High Plains and sure it can get annoying, but that just gives you more of a view of what we do have! - lots and lots of sky! While out making our rounds with the traps we saw plenty of Northern Harriers. These raptors are easily identified by the large white band across their rumps as well as their distinctive flight pattern. They tend to dip and swerve a great deal as well as skim close to the ground, hoping to flush out prey. I saw one chasing a rabbit through a field so we stopped to watch. The harrier was incredibly agile and changed directions faster than I could blink. Despite this, it was having a hard time catching the elusive rabbit. I happened to look behind me and saw another harrier coming in from the south! It had seen the chase and was hoping to steal the prize. Both harriers began chasing the rabbit through the tall grass and diving in and out. Needless to say, both James and I were squawking and crowing with excitement! We had to move the truck to get closer because the chase had taken them too far east and in those few minutes one of them caught the rabbit. We saw the loser on the ground, presumably resting but could not see the winner or his catch. It was a thrilling chase and we couldn't stop talking about it and of course describing everything we'd seen to each other although the other had been less than a foot away the entire time.

We also saw several Red-tailed Hawks out that day, one of which was sitting in a field. When we stopped to watch it took off, the beautiful red tail fanned out and the lower half of a rabbit clutched in its talons! The big excitement that Saturday was the elusive adult Bald Eagle we have seen several times but have been unable to photograph. This is the first wild adult I have seen and they are very wary so it is often difficult to get close enough before they take flight. I'll get you yet Mr. Eagle....

Our only catch was a rather active striped skunk. Many times I have been able to approach a cage trap, prop open the door and slip away without even waking the skunk but that was not the case this time! Skunks are seriously misunderstood and so, thinking to educate my followers, I decided to film it and explain what is really going on with that waddling, stripey critter you may have encountered. As everyone knows, skunks can spray an extremely foul-smelling liquid on predators and things they consider to be threats. What people do not realize is that this is the skunks last resort and it does not want to waste this resource if it does not have to. It takes time to refill its anal sacs with this liquid and if the skunks wastes its main defense on empty threats it is essentially defenseless until it can build up enough liquid again. That would be a problem! A cornered skunk will try a host of threat displays first to try to drive away its assailant. These include stamping its feet, mock charges, head stands and turning to expose its anus and flashing the tail to warn of an impending spray. Therefore, you can count on me, dear followers, to get you this information so you can see for yourself! I belly crawled up to the cage and while James lifted the door and held it, I filmed the skunk in all of his stompy, flashy glory. The skunk was released without incident and everyone went on to have an odor-free and productive day!

So the next time you encounter one of these guys, don't panic. Remember that the skunk does not want to spray you any more than you want to be sprayed and back off so that he can waddle away in peace. I've also found that sweet talking goes a long way too! Thanks for the tip on that Ray!

Bobcats and Bycatch

"Bycatch" is the term we use to signify non-target species we catch in our traps. When trapping for bobcats you will invariably encounter other hungry carnivores with a taste for chicken. Relax, no roosters are harmed in the making of this thesis! We house them in separate cages with shade, food and water and they lure the cats (or other critters) in with their crowing. We also use game cameras to monitor some of our more popular trap sites to see who's sniffing around and to scout out potential new locations. I've attached a few pictures of the animals I've encountered during my quest to be a Bobcat Rockstar. Hope you enjoy!

My First Blog!

Hello from west Texas!

My name is Lena and I am a graduate assistant at West Texas A&M University. I am currently working on my M.S. in biology and am loving it!! My thesis is on Habitat Selection and Home Range Size in a High Plains population of bobcats. To date I have personally caught 16 bobcats (that includes juveniles and adults) and am also utilizing data that was collected before I took over the project. I plan to graduate in August 2013 so any prospective employers out there - hint hint!

I have also been working on a side project and hope to have the publication wrapped up by the end of Christmas Break. For this, I spent 6 months trapping mesocarnivores and small mammals in Palo Duro Canyon State Park. I've added my capture list to several other graduate students' results (from their respective theses) as well as to data collected by my advisor, Dr. Ray Matlack, to compile a list of the mammals that can be found there.

I created this blog to chronicle my adventures so that people can see what I get to see every day: that nature is a gift and can be appreciated anytime, anywhere. You don't have to be a wildlife biologist or trek to the ends of the earth to see something spectacular, just look in your backyard! The neighborhood park! The potted plant sitting next to you!

I hope you can follow me as I continue on my journey and be at least somewhat entertained!!  :)
