Observation of raptor-avoidance behaviour by a Dusky Woodswallow Artamus cyanopterus

Murray Kelman, George Madani


Abstract

This note describes an observation of a Dusky Woodswallow Artamus cyanopterus employing a seldom observed and unusual defensive behaviour against a Peregrine Falcon Falco peregrinus. Instead of mobbing or fleeing, the Woodswallow hid beneath a branch to avoid detection and potential predation. We discuss various predator-avoidance and defensive behaviours and explain the advantages of hiding as a quick and safer survival strategy. This observation reveals additional tactics used by woodswallows and expands our understanding of avian predator avoidance. Understanding these unconventional strategies broadens our knowledge of defensive behaviours in passerine birds.
