from a freind:
Singing in the trees off the northwest corner of the Sylvan Water. The song was DEE-dee-dee DEE-dee-dee DEE-dee-dee, repeated persistently in a high pitch. That is roughly the pattern of a common yellowthroat, but not exactly (a CYT goes DEE-dee-dee Dee-dee-dee DEE), and the sound wasn't the same. Any other ideas?
email me if you know.
