A few minutes ago my dogs alerted me to a strange sound. It was so unusual I thought it was an artificial sound so I grabbed some personal protection and a powerful light and went for a walk looking for the source. I think we have some new frogs in my little pond behind the barn. I've heard a lot of frogs over the years, sometimes a deafening but not unpleasing cacophony of sound.
This sound was different - tone clean tones, one after the other. I heard maybe 4-5 seconds of a continuous and nearly pure F# tone (above middle C) followed by a similar tone a step higher at G#. Then it repeated, sometimes right away, sometimes with a short pause. It wasn't a distinct trill and wasn't the least raspy, gravely, or warbly.
One frog with two notes? A male and female posting on frog snapchat? I've never lived close to a pond and have not heard this type sound since I dug this little pond, maybe 8 years ago. Maybe everyone else but me has heard this kind of frog! I checked some frog sound ID web sites and couldn't find it. (TN frogs on this one: http://www.leaps.ms/soundpage.htm) I didn't think to try to record the sound.
Anyone know frogs?
