Recorded 4:50 PM (PDT) on May 16, 2020 on iPhone at Lake Poway Park.
Lake Poway Recreation Area is the closest park to where I live. The lake serves water supply to nearby resistants, while the park contains an archery range, a baseball park, picnic areas, fishing and boating areas, and hiking trails. Its a little crowded on a Saturday afternoon despite the coronavirus pandemic.
This recording captures the soundscape of a typical afternoon at Lake Poway park. The sound of birds and nature sounds form the background, with occasionally a bird or two breaking into the foreground. Sounds of people can be heard when they enter a closer proximity to the recording spot. Due to my unfamiliarity with bird calls, I can not identity the species of birds 1 and 2 labeled in my graph.
I completed missed the unknown sound in the graph when recording. In my mind I have associated it with wood hitting something and I had suspected it to be boats hitting the dock, but they seem to be too far away for that sound to be captured.
