The Andean pygmy owl is 15 to 16 cm (5.9 to 6.3 in) long. Males weigh 54.9 to 77.4 g (1.9 to 2.7 oz) and females 54.6 to 75 g (1.9 to 2.6 oz). It has two distinct color morphs; in one the head, most of the body, wings, and tail are dull dark brown with white markings and in the other the same areas are dark chestnut with buff markings. In both the crown has small white dots. They have white "brows" over yellow eyes, white "moustaches", and a broad white throat. Their nape has a black and white face-like pattern. Their backs have spots and the tail bars, white or buff respectively. Voice: The Andean pygmy owl's song is a "long series of rapidly delivered, evenly spaced 'poop' notes" that is sometimes preceded by two whistles.

The cloud-forest pygmy owl is a small owl, 14.5 –16 cm (5.7–6.3 in) in length with a 92.8–96.3 cm (3.7–3.8 in) wingspan. Weight can range from 75.6 to 79.3 g (2.7 to 2.8 oz). The male and female have similar markings and plumage, but as in many birds of prey this pygmy owl may display sexual dimorphism in size, with the female being more than 3% larger and more than 3% heavier than the male. The standard linear measurements are: the tail measures 46.8 mm (1.8 in) and the bill (from cere to tip) measures 11.3 mm (0.4 in). Voice: The song of the cloud-forest pygmy owl is composed of simple notes best expressed as hollow whistles or toots, like almost all New World Glaucidium species. It is a long series of short whistles, delivered in pairs and occasionally in trios. This song pattern is shared with the northern pygmy owl (Glaucidium gnoma) and the Costa Rican pygmy owl (G.
