THMS in da house!
Team SEPTIC listened to bird calls. We wanted to determine bird density as we went up the mountain. We did this by listening to bird calls over three minute increments and recorded the number of calls and the amount of interfering noise.
We learned that there are many uncontrollable factors in nature that make it difficult to study. There was a lot of interference from people, cars, insects, and the shape of the landscape. We also observed that our presence in observing the birds changed the frequency of calls.
We also learned that rocks don’t fly or make songs, so they are more cooperative study subjects. We plan to study them for our research project.
PS: The Forest Service really needs to improve their septic systems!
