ADDITIONAL INFORMATION (If any)
I will submitting two audios. I recorded the calls using a voice recorder that doesn't have a USB connector. I then recorded them onto one that has a USB connector. The first audio is 6:29 long and contains the seven separate recordings that I did between approximately 9:18am and 9:27am on June 8th and the second contains only two recordings that I made between 9:21 and 9:23am. The first contains at least eight calls by the warbler starting at 1:20, 1:40, 2:10, 2:37, 3:00, 3:27, 4:02 and 4:46. Around the 5:00 mark, as I was walking down the embankment to get closer, I dislodged a round rock that rolled down towards where the warbler was and I never heard it again. The second audio contains at least 3 calls, one between 9 and 12 seconds, the second between 35 and 37 seconds, and the third between 58 and 60 seconds.
