The coqui frog is sometimes confused with another invasive
Caribbean species, the greenhouse frog, Eleutherodactylus
planirostris. The greenhouse frog is a smaller, quieter
cousin that lives in similar habitats. Neither species appears
to be poisonous. Coqui and greenhouse frogs have other key characteristics
used to tell them apart (see poster below). The male coqui’s
loud “Ko-KEE” call is easily distinguished from
the cricket-like chirping of the greenhouse frog. Both species
are nocturnal, usually more vocal from sunset and during rainfall,
and the females and juveniles make little, if any, sound. Excellent
recordings of coqui and greenhouse calls can be found at the
Hawaiian
Ecosystems At Risk (HEAR) Project website.
