what makes this call?

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.
