How Hinase Maintains Her Authority Over The Herd
- 5 years ago
Hinase is number 1 in the hierarchy of capybaras at Nagasaki Bio Park. When she approaches most of the capybaras sit up, alert and ready to move quickly if they sense she will be aggressive towards them. She seems to like this behaviour which acknowledges her leadership status, and it usually means she will not chase them.
In this video, the keeper has hidden some pellets in the palm frond among the bed of leaves. Hinase realises this and as she approaches the food Hinase barks and the other capybaras move quickly away. Hinase probably also sends out an ultrasonic communication, at a frequency inaudible to human ears, which the other capybaras react to.
