It is field trip time, and I’m back to Brownsville, TX. The goal of this trip was to relocate all 16 tortoises and find 2 more tortoises to add to the project.
So let’s test you again. Can you find the tortoise in this picture? Be careful not to get fooled by the yucca trunk.

If I give you a closeup picture does that helps?

Here he is.

Don’t be sad if you did not find, those little tortoises are experts in camouflaging themselves with the vegetation. We are able to find them because we have the radio tag, otherwise, it would be very difficult. Even with the help of the radio transmitters, if the animal is tucked under a prickly pear cactus, a woodrat midden, or in this case under a Spanish Dagger (Yucca treculeana) it can take us 10 to 20 minutes to find it.
Basically, we are playing the hot and cold game with the tortoises. Our prize is the animal, the “hunter” is me with an antenna, and the receiver gives the clues. A louder bip means hot, a lower sound is cold. By going in the direction of the loudest sound, you get closer and closer to the tracked animal. It gets to a point where you know where the tortoise is, even if you are not able to see it yet. On the picture below you can see me listening to the receiver.

The area of this picture is very open, which makes it easier to locate the animals. However it is not always like that, the denser and taller the vegetation the harder it is to maneuver around with the equipment.

In the picture above you can see one of our grueling areas. Unfortunately, it is not just a tight walk around, but the vegetations are literally “grabbing” you as you pass by. Your mind needs to be in an “unagi” state. (This is a Friends reference from Ross. However he uses the word unagi incorrectly, the word he means to use is zanshin, which is a term used in Japanese martial arts. Zanshin means “residual mind.” It refers to a state of relaxed awareness in which a practitioner of martial arts is wary of their surroundings before, during, and after attacks.) After three days in the field, we were able to find all animals and the 2 new ones. Other interesting findings during this trip was two juvenile tortoises, two eggs of Common Pauraque (Nyctidromus albiollis), a hog skull, and a Texas indigo snake (Drymarchon melanurus erebennus). There is no picture of the snake because my first instinct was to run for my life. I’m always worried that I will encounter a Western Diamondback Rattlesnake, so if I see anything that resembles a snake, I’m running in the opposite direction.


I hope you enjoyed my second trip, see you next time.
