Abstract

Three methods were explored to eliminate damage caused by owl pellets and fecal droppings: exclusion; trapping; and sound deterrents including abstract sound, biosonic sound, and high frequency sound.

Initial successful results of various types of sound diminished with time to the point that owls adapted and ignored all sound repellents within a short period. Exclusion techniques were ineffective as owls would find ways around, through or between any non-permanent structure blocking entry through warehouse openings. Live-trapping and relocating owls was the only effective technique tested in this experimental program. Three trap methods were found effective, but trap success diminished with use of each method. Thirteen owls were trapped in one warehouse during this study using bal-chatri, goshawk and drop-net techniques. The details of each method are discussed.
