This species is known from four museum specimens and two field reports, and there is no information on its likely distribution extent, population size, trends or threats, although it may be threatened by logging. For these reasons, it is classified as Data Deficient.

Geographic Range [top]

Range Description: Aegotheles tatei of Papua New Guinea is known from four museum specimens and two field reports. Two specimens were taken in 1936 from Palmer Junction close to the Indonesian border, one in 1969 from Nunumai in the far south-east, one unlabelled from the 1920s. One was sighted in 1962 at Brown River west of Nunumai (Pratt 2000, T. K. Pratt in litt. 2000). A previously undescribed grey-morph bird was reported in 2003 along the Drimgas Road, c.17 km north of Kiunga in the Western Province (K. D. Bishop in litt. 2003). If tatei proves to be absent from many suitable sites, it may be classified as threatened on the basis of a highly restricted range but given the difficulties of surveying owlet-nightjars, especially given that the call of tatei is unknown, its status is currently uncertain.
