African wolves (AWs) are sympatric with endangered Ethiopian wolves (EWs)
in parts of their range. Scat analysis have suggested dietary overlap
between AWs and EWs, raising the potential for exploitative competition,
and a possible conservation threat to EWs. However, in contrast to the
well-studied EW, the foraging ecology of AWs remains poorly characterized.
Accordingly, we studied the foraging ecology of radio-collared AWs (n = 11
individuals) at two localities with varying levels of anthropogenic
disturbance in the Ethiopian Highlands, the Guassa-Menz Community
Conservation Area (GMCCA) and Borena-Saynt National Park (BSNP),
accumulating 845h of focal observation across 2,856 feeding events. We
also monitored rodent abundance and rodent trapping activity by local
farmers who experience conflict with AWs. The AW diet consisted largely of
rodents (22.0%), insects (24.8%), and goats and sheep (24.3%). The overall
foraging success on live rodents (proportion of successful foraging
attempts) by AWs was 20.7% was higher in the farmlands (36%) than in other
habitat types (<17%). Of the total rodents captured by farmers
using local traps during peak barley production (July to November) in
GMCCA, totaling 24 rodents per hectare per day, 80% were scavenged by AWs.
Of all rodents consumed by AWs, most (74%) were carcasses. These results
reveal complex interactions between AWs and local farmers and highlight
the scavenging niche occupied by AWs in anthropogenically altered in
contrast to the active hunting exhibited by EWs in more intact habitats.
While AWs cause economic damage to local farmers through livestock
predation, they appear to play an important role in scavenging pest
rodents among farmlands, a pattern of behaviour which likely mitigates
direct and indirect competition with EWs. We suggest two routes to promote
the co-existence of AWs and EWs in the Ethiopian highlands: local
education efforts highlighting the complex role AWs play in highland
ecosystems to reduce their persecution, and enforced protection of intact
habitats to preserve habitat preferred by EWs. Feeding records-Fig
