Brooks vs. Ogilby's Duikers

I know the range for these 2 duikers are not supposed to overlap but I think a lot of the Brooks duikers we see are Ogilby's. The backs are often very rounded and the Brooks duikers are shown to have flat backs. Isn't it possible the duikers cross over the areas? I say brooks because of the area but I am never sure.

Brooke's and Ogilby's live in different forested areas separated by large expanses of unforested areas, so it's quite unlikely that you could find Ogilby's here. I wouldn't be too worried about the back shape as it changes considerably with posture.

Brooke and Ogilby's were long considered the same species and geography is one of the main things that differentiates them 😃 you can even find references that classify them as different subspecies only http://www.ultimateungulate.com/Artiodactyla/Cephalophus_ogilbyi.html although now many recognize them as different species: http://www.iucnredlist.org/details/4148/0
