[6] The species is named for its unusual blueish gray color.

[3] Specimens have been found active along trails during the day as well as active on the ground just before dusk, calling among low-lying vegetation some 1 metre above a stream.

[3] Montane forests in the range of this species are generally highly threatened by agricultural encroachment and logging.

[1] However, it occurs in several protected areas, including Bwindi Impenetrable National Park in Uganda, Kahuzi-Biéga National Park in the Democratic Republic of the Congo, Bururi Nature Reserve in Burundi, and Gishwati Forest in Rwanda.

[1][3] It is also likely to occur in the Virunga National Park, Democratic Republic of the Congo.
