In September 2024, a renegade rodent dominated local news and radio stations (including BBC Radio 1!). Cinnamon, a juvenile capybara born at Hoo Zoo and Dinosaur World in Shropshire, escaped captivity to live what the zoo described as “her best life” in nearby woodland. Live traps, on-foot searches, and thermal imaging were all used to try and recapture Cinnamon before she wandered onto neighbouring MoD (Ministry of Defence) land. After a week of monitoring, tracking, and holding their breath, zoo staff finally reunited Cinnamon with her mother, father, and brother Churro.[1]

13th September: The Great Capybara Escape

On Friday 13th September 2024, unsuspecting zoo keepers entered the capybara paddock to cut the grass. Unbeknownst to them, Cinnamon, a one-year-old capybara roughly the size of a spaniel, was lurking in the long lawn. Reports differ as to whether she was startled or sneaky, either way, Cinnamon slipped around the side of the tractor to escape the enclosure.

Joint owner of Hoo Zoo and Dinosaur World, Will Dorrell said:

“Our two young capybara here are always trying to work out a different way of trying to cause us headaches.

They’re extremely intelligent which a lot of people might not necessarily appreciate.

She seemed to know what we were going to do and was waiting there ready for that gate to be opened.”[2]

Hoo Zoo predicted that Cinnamon would likely head for The Humbers and surrounding fields. She was initially spotted close to the Humber Brook River near the zoo’s northern border. An area Mr Dorrell describes as “a capybara’s paradise” because of ample food (grass) and ponds.[3] Cinnamon eventually moved outside the zoo’s perimeter into zoo-owned woodland bordering a site belonging to the Ministry of Defence (MoD).

Thermal Cameras Track Renegade Rodent

Having broken free of the zoo’s perimeter, search parties and a thermal drone were deployed to scour neighbouring zoo-owned woodland for Cinnamon. Thermal footage, captured during the night, showed that Cinnamon had taken refuge in a field approximately 200m away from her paddock. A thermal drone was used the next night to track the renegade rodent’s activities. Hoo Zoo revealed in a Facebook post that:

“Last night our keepers were again working through the night to try and recapture Cinnamon.

She was spotted again by a thermal drone within 5m of the same location from Tuesday night.

Unfortunately this area is extremely dense with almost impenetrable undergrowth that Cinnamon can easily move under but we cannot.”[4]

Hoo Zoo attempted to recapture their absconder using live traps (harmless cages with automatic doors) and capybara noises. However, Cinnamon was not fooled. Mr Dorrell explained:

“She actually has now made tracks around the side of the cages.

So she’s obviously seen them and decided she’s walking around them rather than through them.”

~ Will Dorrell, Joint Owner of Hoo Zoo and Dinosaur World

Thwarted by capybara intelligence and dense undergrowth that only thermal imaging and Cinnamon could penetrate, Hoo Zoo halted rescue efforts to avoid scaring their furry fugitive onto a neighbouring MoD site. Had she breached this border, recovering her would have become almost impossible. The zoo explained in a Facebook post that:

“At present [Cinnamon] is comfortable, content, not short on food and not at risk to predators so it’s better that we take our time and recapture Cinnamon with the least amount of stress possible.”[5]

Thermal Imaging Improves Animal Welfare, Conservation, & Rescue

Cinnamon is far from the first creature to be monitored, tracked, and rescued with the help of thermal cameras. As thermal imaging relies on infrared energy, rather than natural/visible light, to create a picture, thermal cameras, monoculars, and drones do not require good visibility to function effectively. Consequently, these IR imagers are perfect for detecting animal heat signatures, including that of a small capybara hiding in dense undergrowth. As a result, professionals can locate and monitor the welfare of animals from a safe, non-intrusive distance; in challenging environments; and at night.

20th September: Capybara Captured

After a week of careful thermal monitoring and unsuccessful live traps, Cinnamon was finally recaptured. Fortunately Cinnamon did not cross onto MoD land; although it did take a team of ten an hour to retrieve her from the lake where she was likely “living her best life.”[6]

Becky Dorrell, joint owner of Hoo Zoo explained how the team:

“slowly herded [Cinnamon] into a spot where we could put the cage that we had and [we] just sort of coaxed her in.”[7]

Thankfully, a scratched nose and pot belly were the only remnants of Cinnamon's escapades into the wide world. She was soon reunited with her brother and parents who were said to be “very disappointed in her” initially but soon forgave their adventurous daughter.[8]

Safe, sound, and back in her enclosure, a belated capybara birthday party is planned for later this month (October) as Cinnamon missed her, and twin brother Churro’s, first birthday in all the excitement of being on the run. That is of course provided she doesn’t make another break for it. Joint owner Will Dorrell has reported that:

“[Cinnamon’s] got a little bit cheekier because she’s looking round her paddock now and sticking her head up to look over the other side.

She’s clever, which is probably why she managed to escape and why she took so long to catch.”[9]
