Black-capped screech owl
The black-capped screech owl, also known as the variable screech owl, is a species native to Argentina, Brazil, and Paraguay. It is distinguished by its blackish crown, prominent ear tufts, and variable plumage morphs (brown, rufous, and gray). This owl typically inhabits lowland rainforests and forest edges, hunting insects and small vertebrates.

About Black-capped screech owl
The Black-capped Screech Owl
The black-capped screech owl, scientifically known as Megascops atricapilla and also referred to as the variable screech owl, is a species of owl native to South America. Its range extends across southeastern Brazil, southeastern Paraguay, and the extreme northeastern part of Argentina. This owl is recognized for its distinctive blackish crown, prominent ear tufts, and a light facial disc framed by a dark border.
Description and Habitat
Individuals typically measure between 22 and 23 cm in length. The species exhibits notable plumage variation, appearing in brown, rufous, and gray morphs, with eye colors ranging from dark brown to amber. The black-capped screech owl inhabits a variety of forested environments, including lowland rainforests, areas with dense undergrowth, forest edges, open woodlands, and secondary forests. Its altitudinal distribution varies, being found from sea level up to 600 meters in the northern parts of its range and up to 300 meters in the south.
Behavior and Diet
This owl is primarily nocturnal, hunting from perches within the forest canopy or by foraging within the undergrowth. Its diet predominantly consists of insects, though it is believed to also prey on small vertebrates. The breeding season appears to encompass October and November, though it is not fully defined. Nests are constructed within tree cavities, which can be either natural hollows or those excavated by woodpeckers. Evidence suggests that the black-capped screech owl may exhibit semi-colonial nesting behavior, with individuals sometimes found nesting in proximity to conspecifics.
Vocalization and Conservation
The vocalizations of the black-capped screech owl include a primary song described as a long, fast trill that starts faintly, increases in volume, and ends abruptly. A secondary song features a short, 'bouncing-ball rhythm.' Both male and female owls sing, often in duets, with the female's call being higher pitched. The International Union for Conservation of Nature (IUCN) currently lists the black-capped screech owl as Least Concern. However, specific data on its population numbers and trends are unknown, and it is noted that the species may require substantial forest areas and could struggle in fragmented reserves.
