On late July I started editing on the computer all the good recordings I’ve been collecting over the past couple of weeks. Harsh thing about field work is that after you spend a good couple of hours, and return to the office to check out the audio, turns out only a couple are good. And the number reduce even more so, when you polish it via a spectrogram using the software, Audacity.
Field work is still going with more stationary recorders, which can capture for more hours throughout the day. This way, it captures more birds and other critters like mice, squirrels and bugs. I learned how to use them recently the other day just for 2 hours. Now I just have to listen to the data and check out what kind of sounds !

I love eating dinner outside watching the sun set and feeling the warm day begin to cool down a little. I love sitting around the campfire and hearing the cackling of the wood and watching its shadow dance. I love sharing laughs, stories, and music. I love the smell of marshmallows as they catch just a little bit of fire and get toasty outside and melt on the inside. I love laying down and stretching out my body ready for rest while staring up at the stars. I love being able to see the brightness of the stars, away from city lights, surrounded by the silhouette of trees. I love waking up to the sound of birds chirping feeling the warm sun shining on my face gently waking me up. I love opening my eyes and having the tips of tree branches come into focus as I wake up~
VAFO hosts a summer long event called the summer challenge for staff members. The challenge is to participate in at least three activities outside of the department you work for. I think this is really cool because it gives staff members the opportunity to experience first hand what others do on their day to day. One activity I participated in was learning the reenactment process of shooting a musket. The person leading this activity gave us a bit of historical background before teaching us how to load and fire the musket. This was one of my favorite history lessons because I was able to visualize and feel the weight of the muskets that soldiers had to carry. I was able to take a small step into history and imagine part of what day to day life was like for these soldiers. This helped me understand the importance of preserving historical structures and artifacts to allow people to envision snippets of historical events.
After processing the video footage from our first week of stationary camera deployments, we noticed we were not alone. Most people just recognize her as a shark, but that’s an understatement. She’s a tiger shark. Locals have taken to calling her Tony the Tiger. National Park Service biologists and technicians have yet to encounter one in their many years of diving around Buck Island so my team and I are confident we won’t be crossing paths with Tony while scuba diving.
NPS has been working with multiple collaborators to study the movements of sharks within the monument using acoustic telemetry. Given these recent sightings of Tony in our video footage, NPS biologists are eager to see if they can cross reference these sightings with detections from acoustic receivers installed near our camera monitoring site. We hope to find that Tony is one of the individuals that was tagged in previous years.
Tiger sharks are natural predators to sea turtles. Their serrated teeth allow them to tear through the turtle’s carapace (shell). Even though Tony has been feeding on our study subjects, we’re happy that she’s here. The presence of apex predators is one of the signs of a healthy ecosystem. Believe it or not, they play an important role in structuring seagrass ecosystems. They balance the food web as well as prevent lower levels from exhausting resources.
Healthy seagrass ecosystem = Abundant greens turtles = Tiger sharks
It’s important to understand the significance of top-down control in natural ecosystems in order to better establish conservation and management baselines that could predict ecosystem responses to natural and anthropogenic change.
Yes, as the title suggest this post sure promise bears ♥ … I got the great opportunity to shadow the Wildlife Ranger during a Bear release and a procedure known as Bear Check-Up. As I may have mentioned on my previous post, at Great Smoky Mountains there are approximately 1,600 American black bears, Ursus americanus
As an aspiring Wildlife Biologist, this shadowing was a dream come true experience. It all happened when I arrived at the Sugarlands Visitor Center, when there was a rumor among my co-workers about a bear being brought to Headquarters, and that one of the interns went to see it. I asked my supervisor at the Visitor Center about it, and she told me it had happened earlier, before I arrived. I got sad, but continued my day normally. Then. the intern that assisted on the bear returned showing off these amazing pictures, when he mentions that the wildlife ranger returning for anyone who wants to assist to the release. My face expression changed from serious and disappointed to excited and grinning.
It was funny, because my supervisor came outside to ask me if I was interested in attending a bear release, and before she finished the question, I said: “Yes!, of course!” , and she replied: “Oh, ok you are clearly excited. You are definitely going.”
When the wildlife ranger arrived, they had the bear on the “bear cage”. People were gathering up around, causing a “bear jam” on the parking. Another intern and I went on the ride to release the bear in Chimney Tops Picnic Area, where this bear was caught the night before. It was around lunch time so as you can imagine, it was crowded and the cage caught everyone’s attention. This was good though, as the wildlife ranger had a big audience to educate about the importance of making sure that when out in the field, you want to make sure that you leave no trace behind. Leaving “human” food leads to unfortunate consequences to wildlife. On this case, for bears, they can get sick from it and also it can lead to a harming attack.
Bears in general are omnivorous animals, they can eat everything. Although, commonly they eat berries, if given the chance of a burger or a something sweet such as a donut, they’ll choose it over berries (I would!). Black bears are not aggressive but if they get used to humans, they could fight them over the food. That’s the most common cause for human incidents, at least at the Smokies. These results not only bad for the human but for the bear too, for the management action would be relocation which can result very stressful, and on a worse case and last resort, euthanization.
When the bear got release, it was obviously scared but even more with a huge crowd yelling at you. He ran off the hill, hopefully not roaming around the picnic area again.
We went back to the warehouse, where the wildlife ranger station is, and for my surprise, they had another bear trap from a campground. For this one, I got to assist on the whole process of the Bear Check Up:
- Carrying the bear inside
- Taking physical measurements: Paws, the whole arm, head, neck, body
- Hair and Blood samples for DNA data
- Body Temperature
- Tooth, for accurate aging
- Ear Tag
- Tattoo on the inner lip of the mouth for Id.
The main purpose of the bear check up not only is to monitor in the future the “misbehaved” bear but also making a bad human impression so the bear gets scare of us enough to not to get closer.
After that, we returned to the visitor center to continue with our day. For the rest of the day, I couldn’t stop thinking about this experience. It made me appreciate the opportunities that this internship has to offer and how to use these as a motivation to continue on this career path.
