The Duke Lemur Center recently welcomed the first aye-aye to be born at the center in six years.
Named after the late best-selling mystery writer Agatha Christie, the infant is one of only 24 aye-ayes in the United States.
Third-time mom Medusa gave birth to the baby on June 7, 2017. Both mother and baby have been kept behind the scenes while baby Agatha gains strength.
Born weighing 74 grams, or slightly more than a Snickers bar, she was only two thirds the typical birth weight for her species, so Agatha’s early care was a round-the-clock task.

“Agatha was a unique case,” said Cathy Williams, veterinarian at the Duke Lemur Center, in a news release from the Duke Lemur Center. “She required intervention by the veterinary staff to provide supplemental warmth and formula until she gained enough strength that she could return to her mom full time.”
Between feedings, veterinary staff used a “baby cam” to monitor mom and baby’s behavior.
Now three months old, the infant is thriving. “She’s becoming more active,” says Steve Coombs, Agatha’s primary technician. “She’s tapping branches. She sleeps with Medusa in the nest box, and the interaction I see is mostly nursing. She’s calm, and Medusa is back to her easygoing self.”
Nocturnal primates with bushy tails and bony middle fingers, aye-ayes are endangered on their native island of Madagascar, where logging, slash-and-burn agriculture and hunting are suspected to have cut their numbers in half in recent decades.
Some villagers in Madagascar believe these lemurs are evil omens and can curse a person by pointing their middle fingers at them; hence many aye-ayes are killed on sight.
In reality, Williams said, the aye-aye is one of the gentlest lemur species. “They’re not at all aggressive, they’re extremely curious and energetic and they’re very intelligent — they learn very quickly.”
Agatha’s parents, Medusa and Poe. were deemed a good genetic match by the Association of Zoos and Aquariums’ (AZA) Species Survival Plan (SSP).
Poe arrived at the Duke Lemur Center from his native Madagascar in 1987, and was one of the first aye-ayes ever imported to the United States. At the time, Poe and seven additional animals imported by Duke between 1987 and 1991 represented the only aye-ayes in the world in human care.
Today, all but one of the aye-ayes in North America — as well as others overseas in London, Frankfurt, Bristol and the Jersey Channel Islands — are descendants of these eight founders.
Agatha is the third aye-aye born in North America in the last two years. Her birth is a welcome development for the Duke Lemur Center, which tragically lost four adult aye-ayes last year to poisoning from a natural toxin found in avocados, not previously recognized as a threat to lemurs.
Agatha will stay with her mother for two to three years while she learns how to forage for food, build a nest and other aye-aye survival skills.
Visitors won’t be able to see baby Agatha, but they can see two of the center’s other aye-ayes, Endora and Ozma.
