| + | == Auditory Signals == |
| + | |
| + | * In many species, sexual readiness is accompanied by some form of unique vocalization ('mating call'). |
| + | ** Cows increase bellowing during [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]]. |
| + | ** Sows display characteristic grunting associated with [[Oestrus Behaviour - Anatomy & Physiology|Oestrus]]. |
| + | ** Queens often 'yeow' repeatedly to call the tom. |
| + | ** Mares and Ewes are comparitively silent. |
| + | * Elevated vocalization alerts/signals to males that sexual readiness is imminent. |
| + | * Auditory stimulus is more useful in long-range stimulation than close discrimination. |

| + | == Visual Signals == |
| + | |
| + | * All females display a form of sexual posturing that can be perceived by males. |
| + | * Can be subtle to human observers. |
| + | * Identification of postures takes place easily among members of the same species. |
