Bunny, a 22-year-old chimpanzee at the Maryland Zoo in Baltimore, gave birth to a stillborn baby Thursday, the Zoo announced today.
The Zoo's chimpanzees were given "mourning time" with the stillborn baby, according to Zoo officials.
"This was Bunny's first pregnancy and things seemed very normal up to and including her last ultrasound earlier this week. At this time, we do not know what caused the infant to be stillborn," said Meredith Wagoner, mammal collection and conservation manager for the Zoo, in a press release. "We are glad to note that Bunny is doing very well and shows no ill effects from the birth."
