The rut

Assembled from 38 blocks · 1 evidence · 31 related

1. Story
2. Males establish temporary territories and call continuously as the herds move north. Playback experiments showed females hearing male rutting calls were more than three times more synchronous in expected time to mating than isolated controls, which supplies a proximate mechanism for the birth pulse eight months later.
