21 June 2004 dusk Oroville CA, Butte County, California 3 witnesses

Account

Three people were at a lake launch ramp at dusk when the witness imitated a whistle from a recording. Movement was heard approaching through brush above the lake to within about 200 feet. A light showed eyes low along the treeline, and whistling exchanges continued until the group left in their car.
