This poorly-known species is undoubtedly very rare and has a very small known range. It appears 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 (10 individuals/km2 [population densiy of Oriental Bay-owl P. badius in BirdLife Population Density Spreadsheet] × 936 km2 [20% EOO]), i.e. within the range 2,500-9,999 mature individuals, and likely to be at the lower end due to specific habitat requirements. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
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.
