CINCINNATI — Some zoo workers in Cincinnati are wearing all-black outfits, grunting affectionately, and generally imitating mother gorillas to help a month-old baby adjust to a new home and get ready for a surrogate mother.

Even though some of Gladys’s mamas are men, they are trying to give her a mother’s love. They cuddle her, let her hang on them, lie down next to her, and talk to her with guttural sounds.

‘‘Whatever a gorilla mom would do with her baby is what we have to do with this baby,’’ said Ron Evans, the primate team leader. ‘‘Everything that we can do . . . obviously, I’m not producing milk.’’

He is heading a team of seven to 10 people who work in shifts of eight hours or so to provide the baby with 24-hour companionship. She came from a zoo in Texas, where she was born Jan. 29 to a first-time mother who showed little maternal instinct.
