The National System of Conservation Areas (SINAC) has reported the unfortunate deaths of seven animals following their transfer from the recently closed Simon Bolivar Zoo. This transfer, part of the “Atardecer” operation, saw over 180 animals relocated.
The operation leader and a biologist with SINAC, Pablo Vásquez, announced that necropsies (animal autopsies) would be conducted to determine the exact causes of death. These investigations will be performed by the National University (UNA). Preliminary insights from SINAC suggest that the animals’ prior conditions in captivity—such as their diet, age, and the limited space in their enclosures—might have contributed to their demise. However, definitive causes will only be known after the necropsy results and other tests are completed.
SINAC highlighted the detrimental effects of captivity on wild animals, noting that the inability to exhibit natural behaviors leads to chronic stress. The prolonged confinement with minimal stimuli and inadequate space at the zoo exacerbated this stress, potentially weakening the animals’ overall health.
Compounding the difficulty of the transfer, SINAC reported that the zoo’s managing foundation failed to provide necessary clinical and management records. This omission increases the complexity and risks associated with the animals’ care and monitoring post-transfer.
Franz Tattenbach, Minister of Environment and Energy, assured that the remaining animals are in good condition but continue to undergo medical and behavioral evaluations. “The animals have already begun the quarantine process, which can last 40 or more days depending on the species and the condition of each individual,” he added.
Ongoing veterinary and behavioral assessments are being conducted to monitor the animals’ health. According to recent reports from the Rescue Center, the animals are gradually adapting to their new environment, showing promising signs of improvement.
