This update was written by primate keeper Melba Brown. 

Our western lowland gorilla infant, Moke, is 14 weeks old, and already he recognizes and responds to his name when keepers greet him. Since birth Moke has been very vocal—whenever he wanted to nurse, for example, or when mom, Calaya, held him upside-down—but now he has expanded his vocabulary to include grunts, whimpers and whines. His coordination is also developing quite well, and he is climbing the mesh of his enclosure higher than ever before. Calaya will allow him to ascend ten or more feet before he either whimpers or reaches for her, or she decides it is time to come down.
