Small51 gForest

The Central American pygmy owl is 13 to 18 cm (5.1 to 7.1 in) long. Males weigh 50.6 to 58.8 g (1.78 to 2.07 oz) and females about 56 g (2.0 oz). Adults' crown and nape are grayish brown; the crown has buff to whitish spots and the nape dark "false eyes". Their upperparts and tail are rich brown and the tail has pale bars across it. Their underparts are whitish with reddish brown streaks. The juvenile's crown and nape are gray; the crown is unspotted and the nape's false eyes are sooty. Voice: The Central American pygmy owl's song "begins with 2–4 equally spaced hoots, followed by very brief pause, then series of 6–18 very similar notes, 'huu-huu, huu-huu-huu...'". It is sometimes preceded by trills.

Cloud-forest Pygmy Owl

Glaucidium nubicola

Medium78 gForest

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.
