There is concern about the future of some Caprimulgiformes species, according to the World Conservation Union (IUCN). These species are threatened by loss of habitat as forests are cleared for farming and development.
The Puerto Rican nightjar is Critically Endangered, facing an extremely high risk of extinction in the wild in the immediate future. However, conservation efforts could result in the ranking being changed to Endangered, facing a very high risk of extinction in the near future.
The Itombwe nightjar and the white-winged nightjar are Endangered. Only one specimen of the Itombwe nightjar was found in the Democratic Republic of the Congo. White-winged nightjars live in Bolivia and Brazil. When this species was discovered in Paraguay, it was a sign that the population was larger. The species ranking was changed from Critically Endangered to Endangered.
Two Indonesian species, the satanic-eared nightjar and Bonaparte's nightjar, are Vulnerable, facing a high risk of extinction in the wild.
