Spring has officially sprung at the Zoo, with the explosion of animal births including a critically endangered Mongoose Lemur, two endangered Francois Langur’s, an endangered White-handed gibbon, a Hoffman two-toed sloth and a Humboldt penguin chick, considered Vulnerable by the International Union for Conservation of Nature (IUCN). All of the infants are doing well and are on exhibit at the Zoo - just in time for the holiday weekend.
