Capra pyrenaica
The Spanish ibex has a unique way of signaling others when a potential predator has been spotted. First the ibex will have an erect posture with its ears and head pointing in the direction of the potential predator. The caller will then signal the other ibexes in the group with one or more alarm calls. Once the group has heard the alarm calls, they will flee to another area that is usually an advantageous vantage point like a rocky slope where the predator cannot reach. The ibex usually flees in a very coordinated fashion that is led by an experienced adult female in female-juvenile groups and an experienced male in male-only groups. This possibly allows the group to escape in a more efficient way as the more experienced ibex will know which slope to run to. However, since their alarm calls consists of an abrupt explosive whistle, it can easily be heard by predators and quickly be located even from a distance.
