Re: [cobirds] Recording/sonogram of Dickcissel from Canon City and comparison with one in Prowers County

An interesting difference between the two recordings. The Dickcissels I heard last month in Morgan, Washington, and Yuma Counties while doing BBS routes were all similar to SeEtta's Canon City area recording. In those counties, I haven't heard birds singing the song type recorded by Nathan Pieplow in Prowers County. Birds of North America Online reports there is individual variation in song within populations of Dickcissels, but no differences between populations. The BNA account also notes that Dickcissel vocalizations have not been well studied.

I have also uploaded a recording I made of the Dickcissel I found in Canon City last week with a sonogram from Xeno-canto.org.  I have wanted to get a recording of one of the Dickcissels that come to Canon City to breed as it has been my experience that they tend to sing a song that is different from the Dickcissels I have heard singing in far eastern Colorado.  This is the first time I have uploaded a recording to Xeno-canto and getting my recording converted to the correct format, etc took a little time.  I have borrowed a recording that cobirder/recorder/vocalization specialist Nathan Pieplow did ( Creative Commons Attribution-NonCommercial-NoDerivs 2.5 ) of a Dickcissel in Prowers County to show the difference in the song of the Canon City Dickcissel.  I have uploaded both of these to my Birds and Nature blog .
