On the evening of the 17 of May, 2008 I was accompanied to my main research area by fellow researcher, Bob Eldridge, from New Hampshire.
We spent the next two hours walking along the roads and tractor paths that run through the oak – hickory forest. Other than several outbreaks of vocalizations from a: Barred Owl Barred Owls and the ever present: Whip-poor-wills Whip-poor-wills the evening was very quiet.
Upon returning to my vehicle I decided to try out a new sound blasting technique that I had been shown recently by John Andrews of Washington State. I had just purchased a Western Safety 50 watt battery powered megaphone. John Andrews does some awesome calls using this system and I was hoping to copy him. I did two or three calls but the night air was still without any type of response at all. So we drove four miles and got ready to try it again. I let out one call with no responses and then let out a second call. What we heard back was not what I expected. Upon first hearing the three short calls that we heard and recorded my thought was wow, someone is answering us from a ridge about a half mile away from us. I did another call but nothing further was heard.
It was now after midnight and we decided to call it a night. I drove home and uploaded the sounds on my computer. The calls I recorded were distant and faint, and most surprising short. My friend had mentioned to me in the field that the returned call almost sounded like my voice. I thought that odd but upon listening to them I tend to agree. Was someone or something a good enough mimic to not only return my call but also make it sound somewhat like my voice?
