Alpine newt courting is very complex, and it has three phases. When a male has found a female, he follows her and positions himself in front of her. This first phase, called the “orientation display,” serves to help the amphibians decide whether they are a reproductive pair.
If the female stays still, the male begins to fan his tail, and he starts a “static display.” The male moves the fan of his tail to one side of his body, and the tip is addressed toward the female’s head. The male also performs a “lean-in,” stretching his hind legs and remaining suspended like that for a few minutes to an hour. Meanwhile he displays the “cat-buckle,” which serves to visually increase the height of his crest. In this position, he comes closer to the female by fanning his tail, and he touches her with his flank or tail. All of this movement serves to hypnotize the female. Then from his cloaca the male releases pheromones that induce the female to breed.
The third and last phase of alpine newt courting is the “spermatophore-transfer display.” The male moves away from the female, and she follows him. He moves slowly, so she normally gets to touch his tail. After this, the male releases one to five spermatophores, gelatinous masses with a sperm tip, and they are left on the ground. Leading the female onto the spermatophore, the male stops the female by standing perpendicular to her, so the two form a T shape. In this “brake” position, the female’s cloacal lips finally collect the spermatophore’s white tip of sperm.
