After filming many sambar this year and observing them closely i will disagree with the "not grazers" as they graze far more often than the casual observer may think,many hunters have been schooled in this line of thought,however it is wrong as we have personally (many many times) observed them grazing,attached is a pic i took only last Saturday of two hinds grazing.And yes they are indeed browsers of course,not disputing that at all.
I watched this pair for 45 minutes in the hope that a stag might appear for a pic opp to no avail, however they never lifted their heads from the dry feed on the ground.

I have other pics posted of other deer grazing also.

As i type i have just got in from a snakes hiss on the lemon tree and the smoke is extremely thick from the current fires.
