What is the courtship vocal display of a male common coquí frog called?

The courtship vocal display of a male common coquí frog is called the co-quí call.

The call has two prominent parts that sound like “co” and “quí.” The first part helps establish territory, while the second is associated with attracting females. This two-part structure gave the frog both its common name and its scientific name, Eleutherodactylus coqui.

Male common coquís call mainly at night from vegetation, rocks, or other elevated locations. Their calls can dominate the soundscape of Puerto Rico, where the species is native. Unlike many frogs, the common coquí does not depend on standing water for laying eggs; it deposits eggs on land, and the young hatch as miniature frogs rather than free-swimming tadpoles.

People sometimes write the call as “co-kee,” “ko-kee,” or “coquí.” These spellings represent the same familiar two-part vocalization. The name is not a separate call made only by females; the conspicuous territorial and mating calls are produced by males.
