Field Expedition Notes for March 2018

Our member Steven J writes “Here are some initial audio recordings we captured while in our research area this past week. I will be posting more as I locate them from the field data. The first recording is of our usual unknown animal, and I am comparing it to an owl in the video.”

This second recording features our unknown howl followed a little later by coyotes. It is possible the unknown is present with the coyote calls. However, whether we are recording an unknown coyote call, or an unknown caller among coyotes, is unknown.

This last recording is an example of interference the recorder picked up. Weather was good and sky was clear. This particular recording was in the early predawn hours. The crickets and other insects are constant, but notice the shift and tonal differences in the specifically defined pattern. Also notice the “warble”. This is the same recorder from the same night as the two above. Literally, the same recording. I would appreciate any recording specialists or engineers to suggest what this might be.

    Nice vocals! In the first recording I can also hear a couple of rock clacks from 55 to 57sec.

    The interference in the third recording I believe is caused by a certain insect being very close to the recorder. My recorders have picked up that type of sound during the summer months. I have not been successful in filtering this out when I recorded vocals at the same time – very annoying.

      Gudrun, I have considered the insect and agree I most likely have one very close. However, if you turn the volume up you will hear a very distinct electronic noise, like several frequencies “warbling” Very hard to describe, but very digital in nature. I am curious what it is. It is most noticeable in the 2 sections, but it exists throughout the recording to some degree. Need to really turn it up.
