An update on Sid the baby sloth at Bristol Zoo Gardens - 17/08/11

Image of Sid the sloth at Bristol ZooBristol Zoo’s baby sloth is now nearly four months old and growing well.

The youngster, who has been named after Sid the sloth in the popular Ice Age movie, is 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, in late April, weighing about just 500g (1.1lbs) at birth. But Light Cap was taken ill shortly after giving birth and so Sid had to be looked after by keepers.

Despite making a full recovery, Light Cap 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.

Keepers had their work cut out for the first few months of Sid’s life, as she needed feeding every three hours, including through the night, with a combination of puppy milk formula and goat’s milk.

She also had checks by the zoo vet on an almost daily basis to make sure she was developing well. The hard work has paid off as Sid has developed into a strong, healthy and inquisitive youngster, with a particular penchant for green beans.

“We now feed her seven times a day, between 6am and 8pm, with milk formula and vegetables such as cooked sweet potato and green beans, which she loves. She still goes home with a keeper every night so that we can keep a close eye on her and give her evening feeds.”

She added: “It will be a while yet before she goes on show with her parents in Twilight World, as she is still very dependent on us to look after her. She is a fantastic animal and she loves people. It is lovely to have this rare opportunity to hand-rear a baby sloth, although we only hand-rear animals as a last resort.”

Sidone, and her parents Light Cap and Rio, are a species known as ‘Linne’s two toed sloths’, also known as the southern two-toed sloth. Bristol Zoo is part of a European zoo co-ordinated breeding programme for this species.

Sloths are native to South America, and are found in Venezuela, the Guianas, Colombia, Ecuador, Peru and Brazil, north of the Amazon River.

Despite not being at risk from extinction in the wild, habitat destruction and climate change are the biggest threats facing Linne’s two-toed sloths. They are also hunted as food and for their claws and fur, which are used to make necklaces and saddlecloths.

Notes to the Editor:

Sloth facts

  • They are related to armadillos and anteaters
  • There are five species of sloths, in two families – either two toed or three toed sloths. The sloths at Bristol Zoo are Linne’s two toed sloths
  • They live in the treetops of the rainforest of Middle America and the Amazon rainforest.
  • They can grow up to 50 cm (1,8 ft) and can weigh up to 9 kgs and have thick hair to help protect them from rainwater
  • They live solitary lives, only coming together to mate.
  • They spend their whole life hanging upside down in trees and use their long fingernails to grip.
  • They move very slowly as they have a low metabolism
  • They eat mostly leaves
  • They almost never walk on the ground because they would be easily preyed upon, although they do descend to the ground to pass urine and faeces and usually do this every three to four days. 
  • Sloths are extraordinarily good swimmers.
  • They cannot see or hear very well, so their sense of smell and touch is very distinctive.
  • They give birth only once a year (after a 6-11 month pregnancy), and even give birth while in a hanging position.
  • Baby sloths stay on their mother’s belly until they become independent.
  • In the wild sloths usually live up to 12-years-old; in zoos or with human help they can live for up to 30 years.
  • In the wild sloths’ coats are tinged a green colour due to being full of insects and butterfly grubs which help to camouflage it from predators.
