Study Aim and Context
This study examined vigilance behaviour in three feral horse groups, comparing their responses to wolf and human vocalisations. Though genetically similar, the groups varied in predator exposure and human contact.
Key findings
Horses previously exposed to predators showed heightened vigilance.
Wolf sounds elicited more movement and alert behavior compared to human voices across all three groups.
Trotting and cantering increased following exposure to wolf sounds, indicating anti-predator responses.
Behavioural Influences
Environmental context, group size, and human presence shaped behaviours. Mutual grooming and resting patterns varied by group structure, while locomotor responses aligned with predator experience.
Considerations
Observer presence, sound exposure timing, and genetic divergence may have influenced results.
Conclusion
Feralised horses exposed to predators show:
- Increased vigilance
- Greater mobility
- Stronger group cohesion
Their responses to danger are heavily influenced by environmental factors.
Next Steps:
- Examine stress hormone levels
- Monitor behavioural changes over time
- Explore how different environments shape anti-predator behaviours
