That is the thing abouts sounds, they are easily mistaken
There are famous sasquatch recordings called the Sierra Sounds
They match perfectly with some other recordings of an unknown animal

There is still some debate on these sounds as some researchers claim that there is a language being spoken

However my friend Thomas, heard some sounds around Agassi that sounded identical
After numerous days out and recording these sounds, he finally saw what animal was making them
They were made by a coyote,
