VIDEO: Tiny monkey rejected by its mother plays with a teddy

Tiny baby monkey that weighs no more than a lightbulb is being raised by Texas zookeepers after being rejected by its mother

  • Betty the Goeldi’s monkey was born at Houston Zoo in Texas last month
  • She weighed in at only 34 grams – considerably less than the normal 50 grams
  • She was rejected by her mother Kylie and has been hand-reared by zookeepers 


This adorable footage shows an infant monkey that weighs the same as a standard light bulb hugging a teddy bear and dozing off as it has its hair brushed by Texan zookeepers, who are raising it after it was rejected by its mother.

Betty the Goeldi’s monkey was born at Houston Zoo in Texas last month.

Houston Zoo said: ‘On January, 15, 2022, the primate keepers at the Houston Zoo found a surprise waiting for them when they approached the Goeldi’s (pronounced ‘gell-dees’) monkey night house – a tiny baby hanging onto a branch in her enclosure.

‘The team moved swiftly to reintroduce her to her mother, Kylie. In doing so, the animal care professionals found the infant to be significantly smaller than a typical Goeldi’s newborn. Usually, the primates are around 50 grams or larger at birth, but this tiny one weighed in at only 34 grams, about the weight of a standard light bulb.

‘Unfortunately, attempts to encourage Kylie to take the baby – named Betty in honor of the late, beloved actress and animal lover, Betty White – were not immediately successful so the team made the decision to hand-raise Betty while continuing to encourage parental bonding.

‘Betty and both of her parents, Kylie, and father Opie were moved to the Zoo’s state-of-the-art Animal Hospital to further her care under the supervision of the veterinary staff.

‘The Houston Zoo is following best practices established by the Association of Zoos and Aquariums Species Survival Plan for Goeldi’s monkeys which has seen the successful raising of Goeldi’s monkeys in the past.’

The animal park said: ‘To-date, the smallest to be raised to adulthood was 42 grams. 

However, the Houston Zoo care team is cautiously optimistic about Betty’s chances. The team anticipates the hand-raising process to take more than three months.

Throughout which Betty will spend as much time as safely possible with her family, who will always be within sight of their baby.

‘The Houston Zoo’s animal care team has extensive knowledge in hand-raising primates. Late last summer, the team spent months raising a ring-tailed lemur, Cleo, who was smaller than they expected her to be for her 6-week age and not using her hind-legs to grip mom as tightly as she should. Cleo is now making great strides at rejoining her troop.

‘In 2020, the team also hand-raised an infant Schmidt’s red-tailed monkey, Peter Rabbit.

‘Goeldi’s monkeys are small, predominantly black New World primates that weigh around a pound. They live in groups of two-12 individuals in the Amazon rainforest and are mostly arboreal, meaning they can be found up in the trees.’

Houston Zoo added: ‘A female Goeldi’s monkey is pregnant for about five months, after which, she typically gives birth to a single offspring who she carries on her back for about a month before allowing dad to take his turn carrying the baby.

‘Baby’s size and strength is imperative to survival for infant monkeys, and if they are too small or cannot grip onto their parents’ fur, they will not survive un-aided by animal care professionals.’
