This weekend turned up very little good audio. Increased human activity in my Monongahela National Forest research area seems to have put off the vocalizers that I've heard consistently the last few months, or possibly forced them to move out of the immediate area.
I did however find two faint vocalizations while reviewing my audio recordings. The first is a distant, faint howl captured at 11:13PM on June 11, 2010. It's interesting though because its fundamental frequency appears to be about 490Hz, much lower than the typical low end for coyotes. The form is also very flat, similar to the moaning howls recorded from Washington state, and somewhat like the Ohio, Mississippi or Florida howls:
