Sheep are even attracted to a rag that is soaked in placental fluid. The odor is the primary recognition stimulus that the adult sheep has to her baby.
Sticking with the lambs, one courtship behavior that ewes (females) have is that when they are in heat, they will first avoid rams (males) and then grow aggressive in her courtship behavior. She will sometimes passively accept the attention of a ram, turning her head to see what he's doing or waving her tail. More aggressive behaviors may include nuzzling or licking the ram. The ewes in heat frequently urinate, which causes the ram to curl its upper lip, which exposes an organ used to smell pheromones in the urine. This is well-known as the Flehmen response.
