Hi Geoff, Another species to consider is Vesper Sparrow. Your call has the hockey stick start to the spectrogram that is typical for Vesper and separates it from White-crowned. At 74ms it is long for a Clay-colored.

Hi all, I recorded the attached clip in the early morning hours 11 October here in southwestern Pennsylvania. It looks and sounds like a pretty good candidate for Clay-colored Sparrow, which would be quite rare here and also represent a first for my location. Are there any other more likely possibilities I might be missing? It was a warm night so unfortunately there is a lot of cricket noise, but the higher frequencies are fairly clean and can be isolated, at least. Thanks very much, hope everyone is having good listening this fall.
