Searching Behaviour	Approach Sexually Active group of Females,Test for Lordosis,Flehmen	Visual Search,Flehmen	Sniffing & Licking of Ano-Genital Region,Nudging Ewe,Flehmen	Moving among Females	Roaming around Territory	Prowling

Some pheramones are less volatile and need to be detected by the vomeronasal organ.
- Bull,ram,stallion,some extent the boar.
Male closely approaches the source of pheramones and will nuzzle the female genital region.

Vomeronasal organ is an accessory olfactory organ.
Connected to two small openings in the anterior roof of the mouth just behind the upper lip.
Fluid-borne,less volatile chemicals enter the vomeronasal organ through the oral cavity by means of nasopalatine (incisive) ducts.
