Field Observation

For the past several years, scientists have observed a striking decline in frog populations in various ecosystems throughout the world. In an effort to learn more about the causes of this alarming trend, it is imperative that a frog's breeding habits are well understood.And for the elusive South American tungara frog, meaningful observation required lifelike mimicry. Within this perfect anatomical replication, Humanfactors developed a micropump that inflates the frog's asymmetrical air sac, and built a miniature speaker that calls out to potential suitors. These biological mating behaviors were synced and repeated, coaxing the male frogs out of hiding and enabling scientists to collect their data.
