Hi, all. Assuming it's a "flight call" (I'm thinking functional), it sounds and "looks" (spectrographically) good for Le Conte's Sparrow. The flight call is thin, slightly descending, very high pitched, and double banded. That's all a good match to Le Conte's Sparrow's flight call.
But just to ask a stupid question, why isn't this an alarm call of an American Robin? That's an awfully variable vocalization, I realize, but I've heard some that are just like this one. Is there's a chance the microphone picked up a robin in a tree, freaked out by a raccoon or something? Or is this definitely a bird flying over? Anyhow, my vote, for what that's worth, is Le Conte's Sparrow. But I wonder about a non-FlightCall vocalization of American Robin, too.

What is the identity of the caller? Several colleagues and I have a likely candidate, but I'd like to hear additional opinions. Once I get some feedback, I'll post the comments and discussion, and provide some additional background.
