Geographic Variation

Two subspecies currently recognized:

segmentata, described as Hydropsalis segmentata Cassin 1849; type locality Bogotá [Colombia]

Occurs in Colombia and Ecuador. See Detailed Description.

kalinowskii, described as Macropsalis kalinowskii Berlepsch and Stolzmann 1894; type locality Pariayacu, near Maraynioc [Junín], Peru

Occurs in Peru and Bolivia.

Similar to nominate segmentata, but shorter tailed. The distal portion of the outer web of the outermost pair of rectrices is barred whitish, with irregular blackish spots. The inner rectrices have a whitish subterminal band, ca 10 mm from the tip.

Related Species

Phylogenetic analysis of DNA sequence data, from both mitochondrial and nuclear genes, reveals that the Caprimulgidae consists of several small basal clades and four major speciose clades, one of which is confined to the Old World, and three of which are in the New World (Han et al. 2010, Sigurdsson and Cracraft 2014). Uropsalis segmentata is a member of a clade that also includes the genera Systellura, Nyctidromus, Eleothreptus, Setopagis, Hydropsalis, and Macropsalis (Han et al. 2010, Sigurdsson and Cracraft 2014).
