The Yungas pygmy owl (Glaucidium bolivianum), is a species of owl in the family Strigidae. It is found in Argentina, Bolivia, and Peru. The Yungas pygmy owl has been treated as a subspecies of Andean pygmy owl (Glaucidium jardinii) but since at least the 1990s has been accepted as a species in its own right and sister to G. jardinii. It is monotypic.
The Yungas pygmy owl is about 16 cm (6.3 in) long. Males weigh 55 to 58 g (1.9 to 2.0 oz) and females average 66.5 g (2.35 oz). The species has three color morphs, a rare gray one and common and widespread brown and rufous morphs. All have pale dots on the crown, back, and upper wings and pale bands on the tail. Their napes have "false eyes". Their undersides are pale with brownish streaks on the flanks and belly.
The Yungas pygmy owl is found on the eastern slope of the Andes of Peru south through Bolivia into northwestern Argentina. In elevation it usually ranges between 1,400 and 3,000 m (4,600 and 9,800 ft) but can be found as low as 900 m (3,000 ft) and in Bolivia as high as 3,900 m (12,800 ft). It inhabits montane forest and cloudforest with heavy undergrowth... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yungas Pygmy-Owl sighting in Amboró National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 211th most-seen of the 273 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Yungas Pygmy-Owl in Amboró National Park on a given day, against under 5% in July–August and October–May, the lowest months. That is one of Amboró National Park's driest months, with about 90 mm of rain against 340 mm in January. June has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yungas Pygmy-Owl sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Amboró National Park, in our data
Amboró National Park is the only park on Wallace's Line with enough records to rate Yungas Pygmy-Owl sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Yungas Pygmy-Owl is recorded against all the birds logged in Amboró National Park (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
