All of the sounds on this site were obtained by me, or were given to me by my squatching buddies for the purpose of sharing.
Yells are like short howls but different. They have a decidedly human like tone to them, hence the description - yells. Because of its human tonality, some think that it must be a person and therefore, a hoax. Like screams, one needs to take into consideration the context, and I might add, the credibility of the one reporting the yells. However, if the voice cracks during a yell, I will be the first in line to say that it is a hoax.
This example was taken at a place where yells are not uncommon.
Howls can be with a very deep timbre or with a higher resonance. They could be relatively short, 2 or 3 seconds long, or lasting as a long as 10 seconds. The long ones will most likely sound like a siren, starting low then climbing higher in pitch, and then coming back down again. Howls are used mostly as location beacons, much like a wolf or a coyote will do. It is precisely because they are location beacons that they are common in the wee hours of the morning; i.e. “It is time to gather together,” or “Is everybody accounted for?” This is also why one might hear a howl occasionally in the middle of the night, just like a wolf or coyote might do.
This is a medium length howl, perhaps the most comon howl you will hear.
This is the kind of short howl that they try to imitate on the Bigfoot shows.
Wood knocks, like whoops and whistles are used as warnings to other squatches, and or, as location beacons. Knocks are also the safest way for them to communicate without drawing attention.
This is an example of a wood knock warning (assumingly other squatches) that a vehicle is coming. Notice the knock and then it is about a minute before you begin to hear the vehicle coming. The road itself is a dirt/gravel road, therefore, the squatches could either hear the vehicle before my recorder could, or because it was late at night, they were able to see the headlights coming. Either way, it is quite fascinating.
