Two South American monkeys were born in Wilhelma's Amazon house in Stuttgart. Südwest Presse reported the births on November 9, 2026: a pygmy marmoset and a black howler. The zoo said the howler arrived at the end of October and the marmoset shortly before that. Curator Volker Grün said howlers are leaf-eaters, so keepers have to offer enough fresh leaves all year. Adult pygmy marmosets are about 15 centimetres long in the body, with a tail of about 20 centimetres, and a newborn is barely the size of a thumb.
The two families raise their young differently. A howler infant stays with its mother, who carries it through the branches. Among the marmosets, the father and older siblings also carry the baby and hand it to the mother to nurse. Howler infants are pale; only adult males grow the black coat the species is named for. Both species live in the Albert Schöchle Amazon House, opened in 2000. The news is these two births. It is not a count of either species in the wild.
For the classroom
Südwest Presse reported on November 9, 2026, that two monkeys were born at Wilhelma, the zoo in Stuttgart. One is a pygmy marmoset and the other is a black howler. The zoo said the howler was born at the end of October and the marmoset a little earlier. A grown pygmy marmoset's body is about 15 centimetres long, and a newborn is about the size of a thumb. The father and older siblings help carry that baby. A young black howler is pale. Only adult males turn black. The mother carries that baby. The news is these two births, not a count of wild monkeys.
- Why might a whole marmoset family carry the baby, not only the mother?
- How can you tell a young black howler from an adult male?
