Hello Tweeters and OBOL,

Earlier today I sent out a request for information on chickadee song
variation in the Pacific Northwest.
To make that request more intelligible I have posted spectrograms and wav
files of four songs,
BCCH from western Oregon and Colorado,
MOCH from central Oregon and New Mexico,

at


http://www.appliedbioacoustics.com/features/sounds/chickadee/chickadeesong.html

total size of the download is about 700 k.
All recordings copyright Arch McCallum
but you're free to use them for yourselves.

As you will see and hear, Oregon MOCH and Colorado BCCH are very similar,
but there is a diagnostic difference.
I hope to hear from many of you about the songs in your area.
Thanks,
Arch McCallum
