Geographic Variation

None determined. With the exception of the holotype specimen, all Puerto Rican Nightjar measurements come from the same population at Guánica Forest. No information is available on geographic variation in song.

Related Species

The phylogeny of Neotropical caprimulgids is not well understood, however, the Whip-poor-will (Caprimulgus vociferus), Greater Antillean Nightjar (Caprimulgus cubanensis) and the Puerto Rican Nightjar may be closely related. Han et al. (2010) reconstructed a molecular phylogeny of the Caprimulgidae using mitochondrial and nuclear DNA. They reported neither of the traditional subfamilies of nighthawks (Chordeilinae) and nightjars (Caprimulginae) is monophyletic and suggested the nightjar body plan is an old and conservative one. The large genus Caprimulgus is polyphyletic with respect to many other genera in the family, which are often defined by derived plumage traits that likely reflect sexual selection or ecological specialization. A taxonomic revision of the family was proposed based on the combined tree.
