Austral Pygmy-Owl has five primary vocalizations (König and Weick 2008, Norambuena and Muñoz-Pedreros 2012, Norambuena and Muñoz-Pedreros unpublished data):

(1) contact pair call, a whistle with 6 to 7 notes/sec described as huj-huj-huj-huj-huj-huj

For a representative audio recording with sonogram, see audio

(2) territorial call a sharp trill described as truie-truie-yi-yi

(3) nestling call, soft metallic chirps trigigigirrr or trigigick

(4) courtship call a whistle made by both sexes described as tiririi-tiririi and

Also tick-tick calls are usually used before the territorial call (Norambuena and Muñoz-Pedreros, unpublished data).
