This is in the members area of Oregonbigfoot. Just wonder if any of you have listened to it? Its kind of a growling moan. Almost like a bear in great pain. It doesn't sound like any that I've listened to before. There is also some new stuff from Stevens Pass WA.
Incidentally, if you compare the Georgia recording and number six of the Stevens Pass recordings (the one that contains the long, siren-like yells), I find that they are fairly similar... not necessarily in pitch, but in the length of the call and the fact that both recordings begin low, raise to a held pitch, then taper off to a lower pitch.
FWIW, here's an analysis of the pitches heard in these recordings (I'm a musician and used my piano to discern the pitches):
Steven Pass, recording # 6 contains several long, siren-like wails. The sounds begin on one pitch, slide up about two full steps and hold there for between 7-12 seconds, then descend approximately two full steps and trail off. The pitches held in these wails are as follows: ##### above middle C, middle C, ##### above middle C, ##### above middle C, F above middle C, E above middle C, F# above middle C, F below middle C and sliding to middle C, middle C, D above middle C.
The three moans in the GEORGIA recordings are much lower, the pitch-plateau reaching only an E below middle C (a full five steps LOWER than the lowest pitch in the Stevens Pass recordings).
There is one other type of vocalization in the Stevens Pass collection which resembles a chimp screaming frantically (whoo-AH! Whoo-AH! Whoo-AH!). This sound is particularly interesting to me because I heard an identical set of screams VERY close to my truck one night while camping in N. CA. It was so loud, it was equivalent to someone screaming in your face at the top of their lungs through a bullhorn. (Unfortunately, I was asleep when the screams began and did not get them recorded.

) I had never heard a RECORDING of this particular vocalization, however, until I heard the Stevens Pass recordings.
