Montevideo Tree Frog

Fascinating facts about the Montevideo Tree Frog

• In the patchwork of eastern, central, and northern Argentina, south-eastern Brazil, and Uruguay, this tiny arboreal amphibian thrives in open forest edges, grasslands and flooded savannas, showing how flexible a tree-frog can be about its home.
• While most frogs pause when the weather turns cold, these frogs keep snacking, munching on spiders, flies and crickets at a high rate instead of dipping into stored fat, a strategy that sets them apart from the nearby Dendropsophus nanus.
• Breeding happens in permanent ponds and flooded grasslands, so even in a landscape that dries out seasonally, the species can still find reliable water bodies to lay its eggs.

Breeding takes place in permanent ponds and flooded grasslands. In the cool months, Boana pulchella maintains a high feeding rate rather than relying on stored fat, and its diet in Argentine populations is dominated by spiders, dipterans, and crickets.
