Class B First-hand BFRO #63645

Mattole River Watershed (Lost Coast region) resident reporting loud knocks and vocalizations

November 2019 dusk Whitethorn, Humboldt County, California 1 witness

Account

The witness reports waiting alone at dusk at the gated entrance to a remote conservation area when they heard a very loud unfamiliar wail/scream-like call from a wooded slope a few hundred meters away. After additional calls and a pause, a second similarly loud and unfamiliar call answered from a different direction a few hundred meters away. The witness interpreted the exchange as communication between two large unknown animals and doubted a prank due to the remoteness and solitary 45-minute wait.
