Sorry for interruption; having some difficulties w/picture links.
It is not uncommon to see herds of waterbuck visiting the various water holes on this ranch.
There are often two or more zebras accompanying the waterbuck.

This young bull didn't seem to appreciate the zebra's cold nose.
Now on the endangered list, the Addax was once plentiful in the Sahara desert, and is currently native only in Mauritania, Chad, and Niger. These seem to be quite content to call S. Texas home.
