My Bigfoot Story Ep. 178 - Screaming Jays & More Knocking

The forest is alive with screaming jays in today's outing. I also capture a strange whistle and a whole bunch of knocks. At one point I even heard the crashing and breaking of brush. I never saw what made all the noise though. Signs of spring every where. Mosquitoes, frogs, snakes and buds in the trees. So what do you think that whistle was. Comment below.
