Courtship and parental behavior of Dendrobates auratus were studied in the field and in captivity. Males are nonterritorial, but occasionally engage in aggressive competition. Males call to attract ♀ ♀ and lead them to oviposition sites in leaf litter. Courtship includes elaborate tactile interactions between partners, with the ♀ taking the more active role. Parental care is performed by the ♂ and includes tending of eggs and transport of tadpoles to water. Males can care for >1 clutch simultaneously. High ♂ parental investment may lead to a shortage of ♂ ♂, limiting ♀ reproductive success. This may result in interfemale competition and a partial reversal of the usual sex roles in courtship.
