Habitat:
This species is found in very open montane and transitional forest, with many clearings and a dense understorey, and probably occurs up to 2,500 m at least (based on Glaucidium spp. heard calling at this altitude at Nyungwe, almost certainly G. albertinum [Dowsett-Lemaire 1990]). Its diet includes invertebrates, with a beetle and a grasshopper in the stomach of one bird (Holt et al. 2020). Its breeding ecology is unknown (Butynski et al. 1997).


Range:
This species is known from just five specimens, collected in the Itombwe Mountains (two specimens) and in forest west of Lake Edward (two at relatively low altitude [1,100 m] were originally identified as G. capense castaneum [Prigogine 1953] and may need re-examination [F. Dowsett-Lemaire in litt. 2000]), Democratic Republic of Congo (DRC), and one from Nyungwe Forest, Rwanda. There is a sight record from Kahuzi-Biéga National Park, west of Lake Kivu (DRC). It may be fairly common in parts of Itombwe (T. Butynski in litt. 1999) - as a nocturnal species, it may have been under-recorded by past ornithological surveys. The song of a barred owlet, assumed to be of this species, was heard in Nyungwe, Rwanda at the altitude of 2,500 m (Dowsett-Lemaire 1990) and there have been only two further undocumented records in 2015 and 2018 (eBird 2021); it is evidently very rare in Nyungwe (F. Dowsett-Lemaire in litt. 2016).


Conservation:
Conservation Actions Underway
CITES Appendix II. It occurs in Kahuzi-Biéga National Park and Nyungwe National Park. Itombwe Forest has been gazetted as a community reserve, although the boundaries still need to be defined (A. Plumptre in litt. 2007). Other parts of the Itombwe Mountains are not protected.

Conservation Actions Proposed
Reassess its taxonomic status. If the taxon is confirmed as a species, survey its distribution and status within the projected range, once the security situation permits this. Once a baseline population estimate has been obtained, continue to monitor population trends as long as the security situation is conducive. Monitor the loss and degradation of habitat within its range. Increase the area of suitable habitat that has protected status.
