The Chocó poorwill (Nyctiphrynus rosenbergi) is a species of nightjar in the family Caprimulgidae. It is found in Colombia and Ecuador.

For a time it was treated as a subspecies of ocellated poorwill (Nyctiphrynus ocellatus) but plumage, vocalization, and genetic differences show it to be its own species. It is monotypic.
The Chocó poorwill is 19.5 to 22.5 cm (7.7 to 8.9 in) long; one female weighed 52 g (1.8 oz). Adults are generally variations on dark brown.

The breast is brown with cinnamon barring and speckles, the belly and flanks blackish brown with dense narrow grayish white bars. Juveniles are similar to adults but lack the two white spots on the wing and their back... Wikipedia →
