The ribbon nightjar ( Lurocalis semitorquatus ), syn. Caprimulgus semitorquatus , is a species of bird from the family of the night swallow (Caprimulgidae).
It was previously considered to belong to the Andean night swallow ( Lurocalis rufiventis ).
It occurs in Argentina , Bolivia , Brazil , Costa Rica , Ecuador , Guatemala , Guyanas , Honduras , Colombia , Mexico , Nicaragua , Trinidad and Tobago , Peru and Venezuela .
Their distribution area includes subtropical or tropical moist lowland forest and swamps , typically at least partially tree-covered habitats up to 1200–1450 m altitude.
description
The ribbon nightjar is 19–29 cm tall, the male weighs between 82 and 89 g, the female between 79 and 81 g. The sexes hardly differ. Overall, the nightjar is very dark. The top is dark brown, speckled and mottled reddish brown. A wide white crescent-shaped throat patch is the only white. The short, rectangular tail is striking. In the resting position, the wing tips protrude clearly beyond the tip of the tail. In flight there are no characteristic features apart from a bat-like flight behavior.
voice
The call of the male is described as repeated, Limikolen -like whistling “too-it” or “to-ic” or as a hard “kit-kit-kit”.

- L. s. semitorquatus ( Gmelin , 1789), nominate form - Colombia, west and south of Venezuela, Guyanas, extreme northwest of Brazil; probably also in Trinidad and Tobago
