Yesterday I had a chat with a friend anxious to know why last year he saw so many bleached skeletons of wildebeest in Tanzania.

What is really puzzling is why only the wildebeest.
The dreadful anthrax and rinderpest couldn't be the cause. They are far too serious to be ignored.

A disease striking the wildebeest is likely to strike other bovideas like antelopes and buffalo.
Why only the wildebeest?

Has anyone a hint?
