Kate recorded this the other morning while walking The Dog in the neighborhood. The audio contains two distinct calls from one bird. When she got home, she said, "Listen to this -- what do you think it sounds like it's saying?"
I listened to Part 1, a two-syllable call, and I said, "[deleted to maintain suspense.]" Kate said, "Yes!"
I listened to Part 2, one syllable, and I said, "[DTMS]." Kate said that's what she heard, too.
So you tell me, what is this bird saying?
