Tawny-bellied screech owl
The tawny-bellied screech owl is a species of owl found in the lowland rainforests of South America, inhabiting countries like Brazil, Peru, and Colombia. It is distinguished by its dark gray-brown plumage with buff spots and streaks, and its distinctive vocalizations, which vary between subspecies. While generally widespread, its reliance on mature forests makes habitat destruction a significant concern.

About Tawny-bellied screech owl
The tawny-bellied screech owl (Megascops watsonii) is a species of owl native to the diverse lowland rainforests of South America. It is found across a wide range of countries, including Brazil, Peru, Colombia, and Venezuela, inhabiting primarily old growth and mature secondary forests.
Description and Taxonomy
This owl typically measures between 19 and 24 cm in length. Its plumage is predominantly dark gray-brown, adorned with buff spots and streaks, and it features prominent ear tufts. There are two recognized subspecies, with M. w. usta often exhibiting a more rufous coloration and warmer brown eyes. Historically, it was described by John Cassin in 1849 and has undergone taxonomic revisions, now residing in the Megascops genus, a group that includes several closely related screech owl species.
Habitat and Behavior
The tawny-bellied screech owl prefers the interior of lowland rainforests, often frequenting the undergrowth and mid-story below 30 meters. While M. w. usta can adapt to altered forests near waterways and human settlements, the species generally avoids elevations above 700 meters. It is a nocturnal hunter, believed to feed mainly on insects and potentially small vertebrates, foraging at lower forest levels.
Vocalization and Breeding
Its vocalizations are distinctive, with the nominate subspecies producing a song of rapid, accelerating notes followed by a low trill. M. w. usta's song is similar but slower. Information on its breeding habits is scarce, though nests have been found in hollows of dead palm trees, with one documented nest containing two eggs in September.
Conservation Status
The International Union for Conservation of Nature (IUCN) lists the tawny-bellied screech owl as 'Least Concern.' Despite its widespread presence, the species is poorly understood, and the ongoing destruction of its mature forest habitat poses the most significant threat to its future survival.
