at night. From dusk until dawn males call using a sound with no pause between the notes, and an assumed territorial call . After midnight, however, the calls decrease greatly. In order to attract a mate, the male red-eyed coqui makes calls from prominent perches rather than low hidden locations until it finds a female. Their reproductive cycle is also unique. Members of the genus Eleutherodactylus do not require water as part of the reproduction process, because they do not pass through a tadpole stage. The female lays an egg clutch of 24 to 42 eggs under a thin layer of damp leaf litter or soil. The eggs hatch and a fully formed miniature version of an adult develops. Adults may guard the hatchlings as they develop. Survival On the IUCN Red List the red-eyed coqui is classified as of 'least concern', meaning that in the absence of any threats it is not considered to be close to extinction. This is partly due to the wide range of suitable habitats for the red-eyed coqui's range. Puerto Rico's increasing forest habitat assists in the increase of suitable habitats for the frog. It is not clear how external factors specifically threaten the species, but its predator, the Cuban tree frog (Osteopilus septentrionalis), regulates its population.
