Here at the CMC Zoo: We have a small troop of Howler Monkeys that call our zoo home. Ghelfing is our oldest, and mother to our two other howlers in the troop. Ghelfing was born on October 13, 1994 and came from the Pittsburgh Zoo in 1998. Her two offspring are Bert and Dj. Bert was born October 25, 2008 and his sister DJ as born on September 2, 2009. Their primary keeper said her favorite part of caring for them is they include her in their grooming sessions and make her feel like she is part of the troop as it is a social bonding for them.
