DWARF TREE-FROG Dendropsophus nanus
A tiny, tree-frog barely larger than your thumb-nail. Despite their small size they are active all year round, usually perching fairly low in bushy vegetation overhanging water from where males call looking for a mate. Males can be identified by their conspicuous yellow throat.
