This sitatunga form was recorded on Nkose Island in Lake Victoria. Adult males observed in 1915 were dull mouse-coloured; the animals reportedly browsed bark in dense dry forest. Uganda’s 2016 assessment instead lists deepwater swampland.
In the account published in 1916 after observations in 1915, adult males were uniformly dull mouse-coloured, with no reddish marks on the legs or pale patch on the throat or underside of the neck. The females seen were red; one captured young, about a month old, was bright red with white flecks and spots on the flanks and hindquarters.
Meinertzhagen described the Nkose Island animals as browsers in dense dry forest that ate much bark. He also noted that the small open grass patch at the island’s southern end had particularly few tracks. Uganda’s 2016 national assessment, by contrast, lists deepwater swampland for Nkosi Island. The sources conflict, and neither description is treated here as resolved.
An extinction-risk assessment has not been added yet.
