Behold little Ziggy! This tiny Choloepus was rescued August 6 in a Limón Province village with a bad reputation for trouble. Ziggy’s mother was killed by dogs, an all too-common occurrence in Costa Rica. Whether dogs are pampered pets or sentries for illegal activity, their canine instinct usually classifies sloths as prey. Though orphaned as a result of the attack, baby Ziggy was saved by the dogs’ owners. They called us and, in turn, we enlisted the help of MINAE for this rescue. While Ziggy did not have injuries related to the attack, he was suffering from a tenacious fungal skin condition that causes lesions and patchy hair loss. Fungal infections are notoriously challenging: they take quite some time to eradicate, then even longer for the skin and hair to heal. Just under three months later, Ziggy is doing much better under our care in the NICU. You may notice the bare path under his chin in the video—this is greatly improved from when he arrived. In his intake medical exam, he weighed 580g (1.28 lb) and now, thanks to his good appetite, he weighs 665g (1.47 lb).
Since our first sloth rescue in 1992, we have always aimed to act in the best interest of the sloths of Costa Rica. For over two decades there were no other sloth-only rescue facilities in the world. With so little known about these enigmatic mammals, we basically taught ourselves how to care for them. We expanded when more sloths required rescuing due to development of land for habitation and infrastructure. We have worked closely with the Costa Rican government to ensure we are providing the best possible care within our self-funded means.
Right now the core issue for us is the release of rescued infant sloths. While earlier this year we were working on a protocol for hand-raised sloths, this initiative was recently placed on hold. Our concern: Sloths that are hand-raised due to their mothers’ death or disappearance do not have the life skills to be released into the wild. They do not innately know which trees to forage or what naturally-occurring dangers (such as rivers and hornets nests) to avoid. Unlike newly-hatched sea turtles that inherit distinct survival skills, newborn mammals learn survival skills and self-sufficiency from their mothers. Wild baby sloths spend months with their mothers observing the choices they make. If this cycle is interrupted (most often due to human encroachment in their habitat), there is no other way for the baby to learn what it needs to take care of itself.
Another problematic facet is abandonment due to health deficiencies. When sloth mothers, like other wild animals, observe/sense a deficiency in their offspring many instinctively abandon it—removing it from the gene pool (Darwinism). As rescuers, we try to save the baby from dying, but the conundrum arises when considering it for release: is it safe to reintroduce these deficient sloths back into wild sloth populations?
We are currently involved in a massive genetics study with Swansea University (UK) PhD candidate Rebecca Cliffe in collaboration with renowned geneticist Dr. Sofia Consuegra. This study will provide invaluable data on sloth species and the potential of subspecies as well as genetic diversity—their findings are vital for the success of a release program. We are not the only ones dealing with the genetic reintroduction issue. Scientists just recently raised concerns about the alarming ramifications of mixing genetically distinct populations with the release of more than 90 rehabilitated orangutans into the wilds of Borneo. For full information, please refer to Dr. Graham Banes paper here .
Sweeping statements (made by others) that almost all rescued infant sloths can be safely released has absolutely no scientific or historical data to support such actions, and releasing them without monitoring would constitute inhumane treatment and potentially wreak havoc within their gene pool.
Addenda: Fascinating video featuring Dr. Sarah Bexell discussing the essential survival skills that giant panda babies can only get from their mothers if allowed the proper time together. This parallels our assertion that baby sloths can only learn life skills from their mothers. If orphaned or abandoned, the sloth does not know how to survive on its own. This is why many sloths that were hand-reared cannot be humanely released. At about 16:50 minutes into Dr. Bexell’s lecture, she talks about reintroducing mammals to the wild:
Our third annual Earth Day Almond Tree project is in full swing. For $140 USD, we will plant a Terminalia catappa sapling in our orchard. These trees help prevent erosion, create shade against evaporation, its leaves feed wild and rescued sloths and promote rainforest conservation. This is the most important gift we can give to [ ]
Here s our sweet sloth friend, Marshmallow. His weight has now increased to 1,050 grams/about 2 lbs. and he is looking more grown-up every day. If you ve been following his progress, his coat was much lighter when he was rescued; it s now developing into the most marvelous blend of colors. Marshmallow is curious and observant, you [ ]
In very late February 2016, in nearby Puerto Viejo, a schoolgirl found a newborn Three-fingered sloth that had fallen out of a tree and was all alone. The sloth s mother was never seen and did not return, so the girl s mother called us for help. This baby Bradypus was given a full examination. Its age [ ]

You may recall that adult Choloepus Stacy had suffered a severe injury to her arm, including a fractured wrist, and a painful wait until she was rescued and brought to us for treatment. After a few months of rehab, we were thrilled to release Stacy late last month on the Sloth Sanctuary grounds, over 300 [ ]
We are at the conclusion of Stacy’s rescue story. In the three months of rehabilitation, her fractured ulna has healed and she has regained climbing strength. Stacy graduated to the transitional soft-release Almond Tree enclosure where we observed her progress. When we were confident she was ready for release, we did a final health check [ ]
This is a story of joy and sorrow. Choloepus Stacy was brought to us in a tiny wooden box by a firefighter in September 2015. She was wet, dirty, disoriented and a small baby was clinging to her. During Stacy’s examination, it was obvious that she was unable to move her left arm. It was [ ]
