However, the mortality rate among these newborns, which weigh only 40 grams, is very high—it’s around 50 percent! So it goes without saying that the “ Tierwelt Herberstein ” is doing everything in its power to provide the best possible care for the baby monkeys. “The first 10 days are critical. But our twins have come through them just fine,” reports zoo veterinarian Reinhard Pichler with delight. Monkey twins were also born back in 2013, but only one of them survived the first few days.

An independent monkey family
Mom Freeza is an experienced mother, and Dad Chrisu actively supports her. The baby monkeys, which are about 10 cm long and weigh 40 grams, are always with their parents, clinging tightly to both mom and dad during the first few days. Including the two youngest, there are a total of 7 Liszt’s marmosets in Herberstein.
They got their name because their hair resembles that of the Austro-Hungarian composer Franz Liszt; they belong to the marmoset family. The adult marmosets are about 40 cm tall and weigh up to 450 grams.
