Preaching is the term known colloquially for Sambar stags when they stand on their hind feet and anoint the tree foliage with the waxy deposit from their pre orbital glands.
I have seen hinds do the same to grab a mouthful of leaves but never actually "preach"

Last night just before dark I witnessed as described below in an email to another sambar hunter.

G`day old fella,

I thought I might ask if you have seen much of sambar hinds preaching. I have seen a lot of male sambar preaching and hinds bi-pedaling for leaves but last night i witnessed a mature hind lead two calves a spikey and another hind just out of the bush.
She took the mob along the bush edge to a preach pad/tree and then she 'preached' and I mean preached just as a stag would.
She was up for 1/2 a minute,prob a bit less and then did a "ewe" type 1/4 squat and pissed a good one directly onto the pad hence making her mark,presumably as the lead hind strutting her stuff.
The spikey came after her and preached 3-4' to the right of where she had scent marked with her face,obviously the 'male' spot on the tree,I didn't note him pissing which is unusual.

I thought it was a great experience of course.

And when I left home I said to ******* "I`m not carting my big camera with me tonight and I bet I get an opp" Murphys law eh!

I have been sitting off another mob that were only arriving in impossible light so I carted my camera gear for a week for nothing ha ha..oh lesson learned!
