Meet Sid, the Not-So-Vicious Baby Sloth


Sidone (Sid for short) is a five week old baby sloth, being cared for round the clock by a team of dedicated keepers at Bristol Zoo. She was born in Twilight World to mother, Light Cap, and weighed around 500g (1.1lbs) at birth. But Light Cap was taken ill shortly after giving birth and had to receive veterinary treatment. After a stay in the Zoo’s on-site veterinary centre, Light Cap made a full recovery and was returned to Twilight World. However, she was no longer producing enough milk to feed her baby and keepers had no choice but to intervene to hand-rear Sid in order to save her. The youngster, who has been named after Sid the sloth in the popular Ice Age movie, is believed to be a girl, but sloths are very difficult to sex. She is being looked after by zoo keepers in a special room behind-the-scenes of Twilight World.



Now five weeks old, she weighs 537g (1.2lbs) and is growing well. But she has needed a lot of care from her keepers, including almost daily checks by the zoo vet, as explained by Bristol Zoo’s Overseer of Mammals, Rob Rouse. He said: “Four keepers have been intensively caring for Sid since she was three days old and we’re thrilled that she is doing so well. She is strong, healthy and very inquisitive, and she loves people.”

Baby Sloth Slinks into Rosamond Gifford Zoo


The Rosamond Gifford Zoo is pleased to announce the birth of its 44th Hoffmann’s Two-toed Sloth. Ocabo (Oh-cob-oh) was born on February 9; he is the son of Bite Lip and Beauregard. The name, Ocabo, comes from a Latin American word meaning “head,” and was chosen because of the young Sloth’s exceptionally large skull. After some initial supplementation from zoo staff, Ocabo is thriving and can be seen on exhibit with the other Sloths.

Just Hanging Out With Mom!

Baby sloth clings to mom at Lincoln Park Zoo 1

A one-week-old Hoffman’s two-toed sloth clings to its mother today at Chicago’s Lincoln Park Zoo. The youngster was born on Feb. 15 to the 20-year-old, first-time mom. Despite the mother being new and inexperienced, animal care staff reports that she is being very attentive and caring to the youngster. The baby is nursing, clinging well, and appears healthy. The baby has not yet been named, and its sex is currently unknown. The mother and baby can been seen daily in the zoo’s Regenstein Small Mammal-Reptile House.

Two Baby Two-toed Sloths

Keepers at Loro Parque, in Tenerife, were seeing double this September when mother sloth Bimba gave birth to two a set of twins. Following the birth, the Loro Parque veterinary team stepped in to hand-raise one of the babies as the mother was only able to care for one offspring. Staff member Kirsten became a surrogate mum, tending to the baby Two-toed Sloth at the on-site clinic and taking her "new baby" home every night, where it sleeps next to her bed in a make-shift cot with a toy gorilla for company (see the video!). Both sloths are healthy and progressing well and the park will reunite the twins at a later date.

Meet Ruth the Tiny Baby Sloth

The Rosamond Gifford Zoo has an exceptionally sleepy and exceptionally adorable new addition - a 6-week-old baby Hoffman's Two-toed Sloth. Born underweight, Ruth as she has been named has bounced back thanks to keepers supplanting her nursing with nutritional formula. Now Ruth is happy, healthy and as active as Two-toed Sloth ought to be, which is to say, pretty laid back. Sloths are not on the endangered species list. However, their habitat is quickly being destroyed, leaving them homeless and vulnerable to a decrease in their population size. They are part of a Species Survival Plan (SSP) - a collaborative effort between the Association of Zoos and Aquariums and zoos around the world to help ensure their survival.

Aviarios Sloth Sanctuary Compilation Video

We've covered the great work done by the folks at the Aviarios Sloth Sanctuary in Costa Rica before but this new video of baby and adult sloths at their facility takes the cake.

Meet the sloths from Amphibian Avenger on Vimeo.

We think the Sanctuary's Mission statement sums their work up best: To consolidate our Sanctuary as an agency that promotes and implements the protection and rehabilitation of sloths in Costa Rica, through the observation, study, care and analysis of animals in recovery; to promote actions that raise people's awareness and to facilitate education in order to improve the welfare and quality of life of Costa Rica's two species of sloth.

Thanks to reader Olivia Ross for the tip.

Baby Sloths at Aviarios del Caribe

We have featured Costa Rica's sloth rescue center, Aviarios del Caribe, in the past but never any of their incredible baby sloth videos. Enjoy this recent footage and some older video from the world's only sloth rescue center. 

If you are interested in supporting Aviarios del Caribe, adoption information can be found here. Also note that the center includes a boutique hotel for the adventurous so consider planning your next  vacation to sloth-land. 

Baby Bradypus Sloth at Aviarios Sanctuary

The Aviarios Sloth Sanctuary cares for injured and orphaned sloths in Costa Rica. They also lead sloth education efforts to improve the plight of wild sloths. From time to time, they even have a captive birth, including this baby three-toed sloth called a bradypus or pale-throated sloth. 

At 2 days old, the baby bradypus weighed just 425 grams or 15 ounces!
