Once common along highland streams in western Costa Rica and Panama, the variable harlequin frog (Atelopus varius) is critically #endangered, decimated by the amphibian chytrid fungus. But through years of research and breeding, Smithsonian scientists have created a thriving colony in human care.

In January, we released approximately 500 frogs in Panama’s Colon province as a first step toward a full-scale reintroduction of this species. In order to monitor the released frogs over time, 30 are wearing miniature radio transmitters. They also have elastomer (stretchy polymer) toe markings that glow under UV light—that way scientists can tell which frogs were part of the original study.
Before frogs are reintroduced into remote areas, it’s critical to learn how they fare in the wild and what needs to be done to increase their chances of survival. The locations of the trial releases will allow scientists to easily monitor them.
Researchers are hopeful these trials will provide insight into the challenges faced by a frog as it transitions from captivity into the wild, and ultimately help the Smithsonian and partners create a self-sustaining population in the wild.
