( Todd , 1920)

The cayenne nightjar ( Setopagis maculosa ) is a hardly researched and possibly extinct bird species from the family of the nightjar (Caprimulgidae). It is only known through the type specimen collected in French Guiana in 1917 .

features

The holotype , a male, measures 225 mm. The wing length is 139 mm, the tail length 112 mm, the beak back length 8 mm and the barrel length 17.5 mm. The top is gray-brown. The skull and neck are largely dashed in black-brown. An indistinct, dark yellow band runs around the neck. The gray-brown wing-coverts are brightly yellow-brown spotted. The shoulder feathers are black-brown with broad yellow-brown lines. There is a large white spot on either side of the lower throat. The underside is yellow-brown with strong brown bands. The four outermost hand wings are marked by small white spots and the three outermost tail feathers have broad, white tips. The iris is likely dark brown, the beak is blackish, and the feet are dark brown. It differs from the similar black night swallow ( Nyctipolus nigrescens ) in the lighter and less black plumage and a different pattern of the shoulder feathers.

distribution

Evidence is known of Saut Tamanoir about 10 km above the confluence of the Fleuve Mana with the Rivière Kokioko and of the area around Saül in French Guiana.

Habitat and way of life

The habitat requirements and the way of life of the species have hardly been researched. It is likely found in forests where it inhabits clearings, banks, and open terrain. The type specimen was discovered in such a habitat type near the lower reaches of a gravel river. The diet probably consists of insects.

status

The IUCN lists the Cayenne nightjar in the category “insufficient data” ( data deficient ). In April 1917, Samuel M. Klages caught the type specimen that is now in the collection of the Carnegie Museum of Natural History in Pittsburgh . A possible rediscovery occurred in the area around Saül in 1982 when there were several unconfirmed sightings of night swallows that could represent this taxon . The real status is unclear. If the species still exists, it is likely to be rare and endangered.
