El Paso, Texas (May 31, 2013) El Paso, Texas (May 31, 2013) – The El Paso Zoo welcomes twin slow lorises born at the Zoo on April 26. The babies born to Zoo residents Steven Tyler and Kym Ly have not yet been named, but have been identified as one female and one male.

At birth, the male slow loris weighed in at 25 grams and the female weighed in at 27 grams. 25 grams is equivalent to about 2 tablespoons of white sugar.

“We are excited about our first birth of pygmy slow lorises at the Zoo, especially because they are twins. It’s evident that through our staff’s hard work and dedication, this has been a successful birth,” said Collections Supervisor Griselda Martinez.

This is the first birth for both Kym Ly and Steven Tyler. Staff worked with Kym Ly through positive reinforcement training so that they could monitor her through the pregnancy. Kym Ly learned many commands including how to hold steady for radiographs and exams, how to present her abdomen and mammary glands, among other things. Staff is already working with the babies to learn how to climb on a branch to be weighed so that staff doesn’t have to touch them.

The births are part of a breeding recommendation from the Association of Zoos and Aquariums (AZA) Species Survival Plan® (SSP) to aid in the species’ conservation. Pygmy slow lorises are currently listed as “vulnerable” in the IUCN Red List of Threatened Species™.

Mom and babies are now on exhibit for visitors to see. Visitors may have a hard time seeing them in their exhibit because they are nocturnal animals and they may be sleeping in clinging to mom, in their hammock, deep baskets or nest boxes.

Locally recognized as the Best Place to Take the Kiddos, the El Paso Zoo sits on 35 acres of fun and adventure. Bigger and better than ever, the El Paso Zoo is an expansive green space that is home to exotic animals from around the world and features family attractions such as the African Star train and the Hunt Family Desert Spring. Accredited by the Association of Zoos & Aquariums (AZA), the El Paso Zoo celebrates the value of animals and natural resources and creates opportunities for people to rediscover their connection to nature.
