The Austral Pygmy Owl, *Glaucidium nana*, is a diminutive yet formidable raptor of South American forests. Measuring just 19-21 cm (7.5-8.3 in) in length with a wingspan of 35-40 cm (13.8-15.7 in) and weighing 50-105 g (1.8-3.7 oz), it is the smallest owl in its range. Its stocky build, short tail, and large, rounded head are characteristic, further accentuated by piercing yellow eyes.
