Account

Two forestry workers finishing a pre-dawn spotted owl survey heard a loud, deep yell lasting about five seconds from a canyon below them. The sound echoed through the canyon and struck both as too deep and sustained to be human. They saw no animal and later wondered if the source was responding to their imitated owl calls.
