These males with thick horns and black complexion is called saddle back.

They head the herd and enjoy mating rights.

The tahr is being continuously decimated in many hills. Anaimalais (including Parambikulam and Eravikulam) is most likely to have maximum tahrs. Ashambu hills (KMTR, Neyyar etc) will rank second and Nilgiris with isolated populations may rank 3rd. I beleive in Karnataka tahr is almost completely exterminated.
