The black-capped screech owl is monotypic. It is part of a complex of species that includes the Santa Marta screech owl (M. gilesi), West Peruvian screech owl (M. roboratus), tawny-bellied screech owl (M. watsonii), and perhaps other undescribed species.
The black-capped screech owl is 22 to 23 cm (8.7 to 9.1 in) long. Males weigh 115 to 140 g (4.1 to 4.9 oz) and females up to 160 g (5.6 oz). It occurs in brown, rufous, and gray morphs. All have a light facial disc with a distinct dark border, a blackish crown, and prominent "ear" tufts. Their eye color ranges from dark brown to amber. The brown morph's upperparts are dark brown with pale mottling and vermiculation. The folded wing shows a line of pale spots. The underparts are paler with irregular markings. The other two morphs are redder and grayer respectively.

Rare
Under 5% of wildlife watchers report a Black-capped Screech-Owl sighting in Iguaçu National Park on a given day, based on 97 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 239th most-seen of the 346 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-capped Screech-Owl in Iguaçu National Park on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Black-capped Screech-Owl is recorded against all the birds logged in Iguaçu National Park (97 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.
