Dusky Nightjar
Antrostomus saturatus
The dusky nightjar is 21 to 25 cm (8.3 to 9.8 in) long. A male weighed 52.9 g (1.9 oz) and a female 51 g (1.8 oz). The adult male's upperparts are sooty black with fine reddish cinnamon spots and bars. Much of the face is also reddish cinnamon. The central tail feathers are sooty black with reddish cinnamon bars; the outer three pairs have wide white tips and less barring. The wings are blackish with reddish cinnamon bars. The throat and breast are sooty black with scattered white spots and have a narrow band of white and buff separating them. Voice: The male dusky nightjar's song is "a trilled, double-noted whistle prurrr prureee or prurrrr prruwhip". It is sung mostly during the breeding season, from a perch and rarely from the ground, and may be sung throughout moonlit nights. A flight call is described as "a scratchy wheer."

Rufous Nightjar
Antrostomus rufus
The rufous nightjar is 25 to 30 cm (9.8 to 12 in) long. Males weight 88 to 98 g (3.1 to 3.5 oz) and females 89 to 98 g (3.1 to 3.5 oz). It is almost entirely reddish brown, with a buff collar on the sides and back of the neck and a white band under the throat. The upperparts have dark brown streaks, the wings are spotted and barred with dark brown, and the underparts are speckled with dark brown and white. The wings have no white, unlike those of many others of its family. Voice: The rufous nightjar's song has been interpreted by several authors; two examples are "a loud, staccato chup, whi-whi-RIoh or chuck whip-his-WIDdow, repeated fairly rapidly" and "an energetic, rhythmic chuck, wick-wick-WEEoo." The song is usually given from a perch at any level up to 20 m (66 ft) above the ground.
