Дрімлюга траурний Nyctipolus nigrescens

A fairly small, dark nightjar found in the lowlands and foothills of northern South America. Intricately patterned with dark browns and grays; lacks any obvious features like a collar (although it sometimes shows a small white patch on the side of the neck). Males have small white corners on the tail. Almost always found at a landslide or rocky slope at the forest edge or in clearings, singly or in pairs. Most often detected at dawn and dusk, when it gives a burry “peer!” song and “pip” calls.
