Captive-born collared peccaries learning about their predators: Lessons learnt but not remembered.

Area of Science:

• Wildlife conservation
• Animal behavior
• Behavioral ecology

Background:

• Captive-born animals often lack anti-predator skills crucial for wild survival.
• Reintroduction programs benefit from re-establishing predator awareness in naive animals.
• Memory retention is vital for sustained effectiveness of anti-predator training.

Purpose of the Study:

• To assess the duration of anti-predator behaviors learned through training in captive-born collared peccaries (Pecari tajacu).
• To evaluate the memory retention of anti-predator responses in collared peccaries over time.

Main Methods:

• 11 captive-born collared peccaries underwent anti-predator training sessions.
• Memory tests were conducted at 30, 60, and 90 days post-training to assess behavioral responses.

Main Results:

• Collared peccaries exhibited appropriate anti-predator behaviors (alert, escape, avoidance) immediately after training.
• These learned behaviors persisted for only 30 days.
• By 60 days post-training, peccaries showed no anti-predator responses, indicating significant memory decay.

Conclusions:

• Anti-predator training is effective but requires reinforcement for long-term retention in collared peccaries.
• For successful reintroduction, training must be repeated or reinforced within 30 days of release.
• Memory limitations necessitate strategic training schedules to maximize the efficacy of reintroduction programs.
