We present data on the breeding and biometrics of Common Pauraque Nyctidromus a. albicollis, a species found virtually throughout Middle and South America, including Brazil. We made observations on this species in a forest fragment in south-west Amazonian Brazil, and we evaluated the breeding season in Brazil based on citizen science data. Our field studies between 2011 and 2020 produced 25 nests each with a clutch of one egg. The minimum incubation period was 13 days. Nestling mass was c.8 g on hatching. Searches of the citizen science platform Wikiaves resulted in 253 photographic records of active nests throughout Brazil. These data together indicate that Common Pauraque breeds almost year-round in Brazil, albeit with a peak between the dry/rainy seasons (September–November).
