Brahma and Fiyero, our white-fronted marmosets, are now raising two infants!
An experienced mom, Brahma gave birth on Oct. 2. Marmoset fathers are typically highly-involved parents, and dad, Fiyero, has been helping carry the two babies on his back. This allows Brahma time to rest and maintain her milk supply. The infants are Fiyero’s first offspring.
The animal care team shares that all is going very well, and they will remain hands-off with the marmosets. The sexes of the babies are still undetermined.
The family has access to their publicly-viewable habitat in Primates of the World but may also choose to remain behind the scenes. Stop by to wish them well!

Have you spotted the newest additions to our primate population? The Milwaukee County Zoo has welcomed two white-fronted marmosets: a female, Brahma, and a male, Fiyero. They can be seen in their habitat in the Primates of the World building. Look closely — they’re quite small monkeys!
Also known by the species name Geoffrey’s marmoset, Brahma is 11 years old and transferred from the Staten Island Zoo in New York. Fiyero is 9 years old and arrived from the Chattanooga Zoo. Like all incoming animals to the Zoo, both completed a minimum 30-day quarantine.
The Zoo’s animal care team is optimistic that the pair will breed, and Brahma has previously had many offspring. The team has noticed that she’s the more adventurous of the duo in the public habitat, while Fiyero currently prefers the behind-the-scenes area. As his comfort level increases, guests can tell them apart by noting that Fiyero has a tail, and Brahma does not.
