Population justification: The population is estimated to number 1,000-2,499 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the range is likely to be occupied. This estimate is equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals. However, the estimate is provisional; the population in Brazil may be larger than assumed here (Instituto Chico Mendes de Conservação da Biodiversidade 2018), and hence the population estimate may have to be revised upward if new information becomes available.

Trend justification: The population of White-winged Nightjar is suspected to be in decline based on the large-scale destruction and degradation of cerrado habitat within the whole range and at known sites of occurrence. However, the likely rate of decline has not been estimated.
