Due to this recording's environment, there is a lot of reverberation from the birds chirping, vehicles passing by and the occasional plant life being brushed together. There are over 10 instances of cars passing by, most of which are large trucks - presumably semis passing through on the highway. Throughout the recording there are a plethora of birds calling and chirping. At one particular point in the recording, no cars or trucks pass for over three minutes and the sounds of the birds thrive inside the cave-like environment this recording was made in.

This file only contains a couple, very subtle events. Very far off in the distance around the 12:24 mark you can hear a truck or some sort of automobile driving by. Then at around the 13:53 mark there is a very small chirping sound from an animal or a bird of some sort. The sound is hardly noticeable unless the gain is cranked an extra 6db. The same goes for the last event that happens around the 17:24 mark. There are some birds, perhaps just one bird, calling very, very far in the distance.

This file contains an abundance of wildlife activity. The beginning 2.5 minutes there is a truck passing through the scene and clears the sonic environment at about the 2:27 mark. The author of the recording notes that ambisonics were being recorded on channels 1-4 and MS on channels 5-6 (although the files in this database have been split). From about the 5:45 mark to about the 9:45 mark (about 4 minutes) there are continuous bird calls with very slight variation from the birds; most calls are very distant. There is a noticeable, but gradual, change in the calls between a few birds starting at the 2:25 mark until about the 5:45 mark. After this point, the bird that was calling closer to microphone quiets down and is not present in the space from then on. A notable point in the recording is the entrance of a crow-sounding bird that comes in around the 10:13 mark in the recording. The timbre of the crow's voice and its call is noticeably different from the rest of the birds in this scene.
