Lincoln Park Zoo’s New Baby Sloth Loves Hanging Around

Chicago (February 25, 2011) – Lincoln Park Zoo’s Regenstein Small Mammal-Reptile House gained a new small mammal.  A Hoffman’s two-toed sloth gave birth to a healthy infant on Feb 15. The infant has yet to be sexed or named.

This is the first offspring for the 20-year-old new mother. Hoffman’s two - toed sloth females give birth to a single young which they carry through the forest for up to five months after birth. While the females sometimes mingle in groups the males are more solitary. 

“Despite being an inexperienced new mother she is being very attentive and caring for her youngster,” explained Diane Mulkerin, Lincoln Park Zoo curator. “The baby is nursing, clinging well and appears healthy.” 

This common mammal is native to Central and South America.  Named for their slow movement and large hooked claws they find comfort hanging around high in the trees of tropical rain forests. The Hoffman’s two-toed sloth weighs, on average twelve pounds and can reach a length of twenty-seven inches. They have grayish-brown fur and a pale face although in the wild they may appear green from the growth of symbiotic algae. 

The infant’s mother can be seen daily at Lincoln Park Zoo’s Regenstein Small Mammal-Reptile House. She is nocturnal so while sleeping during the day the infant will be curled up clinging to mom’s chest for comfort and safety.  Make sure to look carefully to catch a glimpse of the baby too.
