Two Wild Foxes Vocalize In Harmony

In I’m pretty sure I befriended one of these guys in Ghost Of Tsushima news, this is a video of two foxes at the Zao Kitsune Mura Fox Village in Shiroishi, Japan forming a little impromptu duet, screaming in harmony. Me? My screaming is usually a solo production performed in front of the mirror of a public restroom after I do something stupid, typically starting with such popular verses as “When will you ever learn?!” and “Dammit turd, get it together!”
