This poorly-known species is undoubtedly very rare and has a very small known range. It would appear to have very specific habitat requirements and, while a large area of its habitat remains, forest clearance and degradation are likely to be causing declines in range and numbers. It therefore qualifies as Endangered.

|Range Description:||Phodilus prigoginei had not been recorded since the type-specimen was collected in 1951 at Muusi, in the Itombwe Mountains, Democratic Republic of Congo (DRC), until its rediscovery in 1996, when a female was mist-netted in the extreme south-east corner of Itombwe Forest (Butynski et al. 1997; Omari et al. 1999). This rediscovery extends the species's known range southwards by c.95 km and lowers its altitudinal range by approximately 600 m (Butynski et al. 1997). Itombwe is not the only forest in central Africa with a large area of highland forest/grassland habitat, and it is possible the species occurs elsewhere, especially in Nyungwe Forest (F. Dowsett-Lemaire in litt. 1999). There is a possible sighting in Burundi from 1974 and, in 1990, calls of an unidentified owl were tape-recorded in Nyungwe Forest, Rwanda (Dowsett-Lemaire 1990). Recent surveys of Kibira and Mt Kabogo, in which this species was targeted, were unsuccessful (A. Plumptre in litt. 2007). |

|Population:||The population is estimated at 9,360 individuals (10 individuals/km2 x 936 km2 [20% EOO]), i.e. within the range 2,500-9,999, and likely to be at lower end due to specific habitat requirements. This range equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. Density from estimate for congeneric Oriental Bay Owl P. badius; see BirdLife Population Density Spreadsheet.|
Trend Justification: This species is suspected to be in decline owing to the continuing destruction and degradation of its habitat. The likely rate of decline, however, has not been estimated.
