Quadcopter 101 Channel EVP Session

This kind of spooked me during a recent test flight for my RC aircraft review channel. Alone in the desert, and not a person around me for miles. It sounds like a voice, but can't make out what it's saying. Is it Native American? Was using a Mobius camera on my hat, which does have somewhat of a sensitive microphone for commentary (that's why I use it as my hat camera)
