We were contacted a few weeks ago by a German ecological consultant on sabbatical, who has been traveling the world for the last year or so.  Starting six months ago she was in Patagonia, then in the Brazilian Pantanal, far upstream in the Amazon, and in Montreal, before volunteering with us for three weeks.  An intrepid traveler, she has been camping in the jungles and couch-surfing the cities of the world before arriving at facility with an open mind and an open heart, sharing wonderful stories from her travels.

What a joy it was to get to know her!  She is a true citizen of the world, and she filled us with hope for the future!  As a global ambassador, her ability to share the wonder of the natural world did her country proud!  Fluent in Portuguese, Spanish, French, and who knows how many other languages, her light shines brightly and we are so happy she came to stay with us for this short while!

Lisa Soehn, you are a spectacular human being!  May that twinkle in your eye continue to spread to all you meet!
Love always from Texas!

What it is like to finish a research trip. – Amy’s Costa Rica Bat Survey Blog cont’d

Costa Rica research life

Where am I?
Yikes, suddenly it is weeks later and I’m back in the United States. Time is a funny thing. When you are on a research trip you are controlled by time, you have a schedule to follow, places to be. There are things you have to do, and they take up all of your attention. As always, you complete your tasks. Then you look up and the whole trip is over. The theme of this blog is the transition from being in the field to coming back to wherever you call ‘home’. I will try to keep it short, but I feel like I just keep thinking of more things to
share to people who would like to start doing research trips but are unsure of what to expect.
The last time I wrote a blog post was over a month ago! Oops! The last few weeks of the trip were dedicated to wrapping everything up: get your data, organize the equipment, make sure everyone is on the same page for what the next steps are after everyone goes home. We made your typical 15-minute presentations the day before departing to the U.S. and everyone did well. After dedicating a significant chunk of your time and energy into a subject, 15 minutes becomes a short amount of time to discuss everything on which you have been thinking and working. But, like I said before, the last couple of weeks were a blur because every day had a plan and there were things that needed to be done.
Then, suddenly, you are transplanted back to from where you came. It is very weird to come home after ‘so long’ in a place much different from here. The trip really does not feel that long now that I am back. Houston, Texas (my hometown) is unlike anywhere else. It’s a lot of driving and concrete. Loud cars and limited wildlife. Days feel very short because things are very fast-paced. This is the polar opposite of Costa Rica. I believe I am experiencing ‘reverse culture-shock’, not only in terms of food and things of comfort, but of the staggering number of people and how ambivalent of environmental woes and responsibilities they are. You spend almost all your time on a research trip surrounded by people who think like you, act like you, understand and empathize with your motivations without need for explanation or dissection. Once that trip is over and you are reinstated into a big city with millions of people, it is an adjustment. But now is where it is necessary to take what I have learned and have been given the chance to see, and teach people and make interactions positive and inspiring. It’s easy to become complacent about the goings-on of far-away countries which do not pose a visible daily connection, especially in a big city where the problems feel disconnected or like your personal impact could not be that much.
Before I go on a rant about living in a big city, I shall get back to talking about the trip. I feel like the trip ended really quickly. At some point, at some lunch, we discussed the Tuckman Model stages of developing a project team: forming, storming, norming, and performing. The performing part is always the most fun and I wish it could happen sooner or longer in a trip. Having to disperse and leave the group after being in a productive groove is my least favorite part of the whole experience. Being back, I miss the people I spent all that time with. I miss the staff and people we met. I miss the food we ate, etc. You get the point. What do I think someone needs to be able to be a successful member of a research team? I would boil it down to flexibility and adaptation. Being able to adapt to change and the inevitable setbacks and redirects a project will have over its course, I believe, is the most important characteristic of a person with whom I would like to spend a significant piece of my time. If my partner is easy-going, patient, and ready to overcome any problem we encounter, that makes a project much easier and less stressful and more of a positive experience because there is someone I can count on to get things done.
After finishing the physical part of data collection, now I am staring at the incoming tsunami wave that is the analysis. Before graduating in May, I have data to analyze, a paper to write, a conference to attend, and a few presentations to give. So, the next few weeks of my life I will be staring at a screen, analyzing statistics and calls, trying to make sense of the data. I will probably cry a few times and read all of the statistics books I can handle. I will update as time goes on!
As always, feel free to contact me (ahall6@stedwards.edu).


What a great illustration of a moth jamming a bat’s echolocation!
Illustration by Chris Tullar from Aaron Corcoran.
This is a great depiction of what goes on in our flight cage every night (albeit with different species)!

Bats have been echolocating for around 25 million years and moths have been evolving defenses against them for just as long.
A bat has to be at the top of its game to make a living out there.

Greetings bat lovers,
This is my second foreign correspondence while I am doing research in Costa Rica (you can find my first blog post further back on this site). To refresh your memories, I am conducting acoustic surveys across Costa Rica using two Wildlife Acoustics SM4BAT Full-spectrum passive recorders to look into the impacts of land use on bat activity and species assemblage. My project is part of a larger NSF funded project led by Drs. Beck and Wasserman looking at the impacts of land-use on primates. My fellow interns are researching antibiotic resistance and hormone levels in primates (these guys get to follow monkeys around and collect fecal samples), water quality of streams entering/inside/leaving forest fragments, fig trees, air quality, and the social implications of eco-tourism. I am the bat lady. We arrived here January 2nd, and after about a week of gathering our equipment and setting up, we started data collection.
What have I learned in my first two weeks here?
1. The weather is the ruler of the quality of your data. Even though it is the ‘dry season’ here in the rainforest, it rains almost every day. Hopefully it will ease up soon because a lot of my recordings are static. Currently, we are at La Selva Biological Research Station. Fortunately, they have a list of over 70 confirmed bat species found in this reserve alone. I plan to compare the findings from the recordings to the list they have to see if we find anything interesting! I have not spent much time analyzing my data yet, as we spend most of our days in the field. While my data collects itself, I am a part of a team and I help the other members collect theirs.
2. Sleep and food are paramount. Field work is no joke and even though I work hard to get 8 hours of sleep a night, I always want more. Those of you comfy in your beds with no assigned time to wake up, I am jealous until mid-March. All of us have already lost weight and our pants are getting baggy even though we eat rice and beans almost every meal! I hope to be super fit by the time I get back to the US.
3. It is very important to get along with your teammates. We are going to be together for 10 weeks, every single day. I love my team and we are making amazing memories here in the jungle. I am excited to get to spend a few days off in Manuel Antonio, hanging out and laughing on the beach with a coconut in my hand! If we did not get along, this would be a very different experience.
4. I am very lucky to have such supportive friends, family, and colleagues. The constant encouragement from everyone makes being away from home very easy. That being said, this is a marathon, not a sprint! I have 8 weeks left and I know at some point all of us will need some TLC and a shoulder to cry on when we are just missing that comfort of home. But I love traveling and know I am fortunate to have such an amazing opportunity to conduct funded research in such a beautiful country on such awesome animals. We’ve done some really cool things: walked across Costa Rica’s second-longest bridge in Tirimbina, climbed a 46 meter high tower overlooking the forest canopy where I got to watch Howler monkeys and White-faced Capuchins flit through the trees just 50 feet away, gone on night hikes and seen Eyelash Vipers and Red-eyed tree frogs, and watched rivers double in depth overnight.
5. It’s all worth it for the bats! So far, I’ve seen Proboscis bats and Greater White-lined bats every day when I walk out of my cabin. I’m sure I will see more species as time goes on. But getting to see their little faces and watching them leave every night to feed is such a rewarding experience. Everyone I talk to is eager to learn all of the fun facts I can throw at them. Many people are surprised to find out not all bats are vampiric (actually less than 1% of the approximate 1200 species drink blood). Anything I can do to improve the understanding, empathy, and appreciation for these bats, I will!
In a couple of weeks the group and I will be leaving for Quepos/Manuel Antonio where we will be doing our research in the National Park and surrounding land. This is a neat tourist town where we will certainly encounter many people who may or may not be familiar with eco-tourism. While my research is going steadily and everyone I talk to is very, very interested in it, I have received disheartening news from the girl doing the social research. She is conducting surveys with as many people as she can, and she has found that many of her subjects have very negative views of bats. Hopefully I, you, and everyone who comes into contact with the Austin Bat Refuge can help change the stigma associated with bats over time to where they can be loved and appreciated for their insane evolutionary history, ecosystem services they provide, and their wonderful personalities.
As always, feel free to email me for any questions or comments (ahall6@stedwards.edu)

Our wonderful friend/intern/volunteer Amy Hall, is heading off to Costa Rica for three months of bat research!
She is working with Dr. Peter Beck from St. Edward’s University and Dr. Michael Wasserman from Indiana University, and her project will use acoustic sampling to determine presence/absence of bat species in various types of habitats around the country.
She will deploy Wildlife Acoustics SM4 (Song Meter) bat detectors and analyze the data using Kaleidoscope tropical acoustic call libraries.

We are so excited for her!
Please join us in wishing Amy all the best and follow her updates when internet connections become available.


Love you little bat!  Go have a happy happy life!

Here’s a last look at you pre-release

You look so good up there! Look at all those quick darting moves! Are you showing us how happy you are to be wild and free?


Huber Limestone Mine bats left their Marble Falls roost and headed towards the Blackland Prairie last night, arriving in Austin and Rock Rock around 11 pm.  There is apparent comingling of the colonies as they hunt, suggesting considerable ebb & flow between the roosts on a regular basis, either nightly or during shifts in short-term weather patterns.


Are these pups playing tag or is this a jam session?  Mexican free-tailed bats have been documented to jam each other’s echolocation signals when competition for food gets intense (see Aaron Corcoran’s research at http://sonarjamming.com) .  Do eastern red bats do the same in similarly competitive situations?  Here in the flight cage, there are not enough  moths for all the 30 plus flying rehab bats. Is this pup following his sibling to practice jamming his call and stealing the moth?  Or just playing?

Action under the black light last night.  Moths attracted by the garden, moth pheromones, night-blooming plants, and the water all tend to congregate around the blacklight.
Our juvenile bats fly in wide loops tangent to the light and hope they time it right so they get the chance to practice their hunting skills.
