The calls of the Mission golden-eyed tree frog are among the loudest of all frogs. They always take place three times in a row and the noise level is comparable to that of a car horn. In 2021, new individuals came from Zurich Zoo to Zoo Vienna. Now, after a break of a few years, there are offspring of these “riot frogs” once again at the Zoo.
“Mission golden-eyed tree frog is particularly exciting because it lives in the treetops of tropical rainforests in the Amazon region. It uses water-filled tree cavities at a height of up to 30 meters to lay its eggs. The people there hardly ever see him, they only know him from his loud calls. The males have two extraordinarily large acoustic sacs,” explains Anton Weissenbacher, Head of the Zoological Department.
