Getting the fog out of the ears again. One of those foggy birds is the difference between Vesper and Song Sparrows. Would you agree that the linked sound file is a Song and not a Vesper? Is the indicator simply the lack of an beginning "clear" pair of notes before the main tune?
Sound file, a 1 meg download; Sound from same location over two days to capture variation. http://home.comcast.net/~soundfiles/Sparrow.mp3 >From there we could discuss the difference of a Pileated vs Flicker in this file when you don't have a referrence volume or drum. For me, warbler brushup is next week. Rich ---- Join or Leave mou-net:http://lists.umn.edu/cgi-bin/wa?SUBED1=mou-net Archives:http://lists.umn.edu/archives/mou-net.html
