This species is listed as Near Threatened because it is thought to have a moderately small population which is suspected to have undergone a decline in the 1990s at least. If the population is found to be smaller, or declining faster, it may qualify for uplisting to a higher threat category.

Geographic Range [top]

Range Description:Lybius rubrifacies is restricted to eastern Rwanda and Burundi, and north-west Tanzania, with a single locality (Lake Mburo National Park) in south-west Uganda (N. Baker in litt. 1999). Although the species is locally common in Rwanda (N. Baker in litt. 1999) (in Akagera NP the population has been estimated at >1,100 individuals [K. Wallin in litt. 2016]), it has a restricted distribution and is presumed to have suffered a population decline since the mid-1990s (Kanyamibwa 2001, Short et al. 1990).

Population [top]

Population:The total population size of this species has not been quantified, but it is described as locally common.

Trend Justification:  The populations is suspected to have been declining since the mid 1990s owing to ongoing habitat destruction (Kanyamibwa 2001, Short et al. 1990).
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:UnknownContinuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in hilly areas of Combretum-wooded grassland, mixed woodland of Albizia-Acacia-Commiphora (including riverine woods) and also cultivated areas with scattered trees (Fry et al. 1988), generally at altitudes of 1,200-1,500 m (N. Baker in litt. 1999). It occurs in pairs and groups of up to five or more, feeding on figs, berries and seeds as well as insects (N. Baker in litt. 1999). Breeding is thought to take place in February-March and October (del Hoyo et al. 2002).

Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):8.5
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): A population decline is suspected since the mid-1990s as a result of habitat loss after the degazettement of about two-thirds of Akagera National Park (from 2,850 km2 to 1,000 km2; Kanyamibwa 2001, Short et al. 1990), due to the arrival of settlers displaced by civil war (del Hoyo et al. 2002). In Tanzania, habitat for this species is not currently under threat, but it occurs at very low densities, due to unknown limiting factors (J. P. Vandeweghe pers comm.).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
It occurs in Lake Mburo National Park (Uganda), Akagera National Park (Rwanda) and Ruvuvu National Park (Burundi) (del Hoyo et al. 2002).

Conservation Actions Proposed
Conduct surveys throughout its range to obtain a total population estimate. Monitor population trends through regular surveys. Investigate factors that are potentially responsible for the species's low densities in Tanzania (J. P. Vandeweghe pers comm.). Increase the area of suitable habitat within protected areas.
