Class B First-hand BFRO #4917

Campers hear late night "banging" near Oroville

September 2002 after 2 AM, dark Oroville, Butte County, California

Account

The witness and four companions camped overnight at Feather Falls campground and went to sleep around 1 AM. Sometime later while still dark, the witness heard rhythmic banging like a large branch struck against tree trunks from two separate distant locations, with patterns repeated back and forth and never overlapping. Companions who heard the sounds attributed them to a woodpecker, which the witness doubted because of the nighttime hour and irregular intervals. No vocalizations were heard.
