Who is Kau Mau and what are his contributions to understanding the Nilgai?

I'm sorry, but I couldn't find any specific information about a person named Kau Mau and his contributions to understanding the Nilgai. The Nilgai, also known as Boselaphus tragocamelus, is the largest antelope of Asia and is prevalent across the northern Indian subcontinent. It's characterized by a sloping back, a deep neck with a white patch on the throat, a short crest of hair along the neck, and white facial spots. Males have a bluish-grey coat and possess horns.

Could you provide more details or context about Kau Mau? Or would you like to know more about the Nilgai?
