No sorry, I do not know. It would be interesting to know though. I do not think that there would be a comparison anywhere.
This is my first attempt at breaking down something like this, but here goes;
Obviously, the two animals are related, the separation between them starts at the Tribal level of the Subfamily level Xerinae of Family Sciuridae
Taxonomies:
Subfamily Xerinae (marmots, ground squirrels, African squirrels, and relatives)
Tribe Marmotini (marmots, chipmunks, ground squirrels, and relatives)
Genus Ammospermophilus (antelope-squirrels)
Species Ammospermophilus leucurus (white-tailed antelope squirrel)
& then
Subfamily Xerinae (marmots, ground squirrels, African squirrels, and relatives)
Tribe Xerini (African ground squirrels)
Genus Xerus (African ground squirrels)
Species Xerus inauris (South African ground squirrel)
I suppose they are as close as transcontinental cousins can be without being an introduced species.
Interesting behavior. I'd also think they would fill the same ecological niche, eating similar foods and being food for snakes, birds and medium-sized predatory mammals (canids)?
Hey, 1JP, where did you photograph your emboldened beast? Anymore info?
This is fun for me. Drool- but I got to go nap now.
