Mantled Hawk Leucopternis polionotus is listed as Near Threatened under criteria A2c; A3c; A4c; C1; C2a(i); D1 because it is thought to have a moderately small population which is suspected to be declining at a rate of 20-29% over 10 years owing to habitat loss and fragmentation.
The species appears to exist at very low densities, prompting Ferguson-Lees and Christie (2001) to infer that the total population is unlikely to exceed the uppermost hundreds. However, this seems unlikely given the estimated Extent of Occurrence of 640,000 km2. Such uncertainty has meant that the species is not listed as threatened on the basis of population size. In addition, no inferences have so far been made about the likely sub-population structure.
Information is requested on this species’s likely population size and sub-population structure, in particular the maximum number of individuals in any one sub-population or the percentage of all mature individuals that form a single sub-population. Further information is also requested on the likely population trend and the estimated rate of habitat loss and degradation. The species’s population trend should be estimated for a period of 23 years (estimate of three generations).
