TASTING THE AIR....
When a red deer stag appears to be "tasting the air," it is performing a specialized scent-checking behavior known as the Flehmen response. The stag curls back its upper lip, exposes its front teeth, wrinkles its nose, and sometimes stretches its neck or holds its head high. Stags use this mechanism primarily during the Autumn rutting season to determine if a female (hind) is in estrus (heat) and ready to mate.
