Taxonomic note
Antrostomus rufus (del Hoyo and Collar 2014) was previously placed in the genus Caprimulgus. Caprimulgus otiosus (Stotz 1996) was lumped into C. rufus following Sibley and Monroe (1990, 1993) and AOU (1998). Note that this taxon was treated as a species in Collar and Andrew (1988) but not subsequently.

Population justification: The global population is estimated to number 5-50 million mature individuals (Partners in Flight 2019). The species is described as 'fairly common' (Stotz et al. 1996).
Trend justification: The population is undergoing a small decline (Partners in Flight 2019). This decline is thought to be caused by ongoing habitat destruction (del Hoyo et al. 1999).
