While overnighting at Mullica Camp several years back, late at night and from the confines of my tent, I heard several coyotes within close proximity to the camp. Since, I've heard packs howling twice (at Spring Hill, and near Friendship's bogs) and recorded them once (along Hampton Gate Road) -- each of these rather recent. None of these encounters were close, but the two times I heard them live, seriously back-wooded, solo, and at an after-midnight hour, I was somewhat spooked.
The howling-sequence recording is rather poor quality, as I had to heavily amplify the file afterward; but this enabled me to identify Wile E. and friends. These guys were probably a half-mile away; good thing my mics are more sound-receptive than my middle-aged ears. If anybody is curious to hear the minute-long mp3, shoot me a howl and I'll e-mail it.
