H. rosenbergi is a nest-building gladiator frog. Lethal fights between males as well as male clutch guarding are common. Males produce five types of vocalization including: an advertisementcall, a courtship call, agressive calls, and a distress call. The mean snout-vent length of male frogs in La Gamba, Costa Rica was 63.1 mm (range 55.7-76) and for females it was 67.2 mm (range 57.4-75.5). Females were significantly larger and heavier than males. The clutches had a single floating layer of eggs embedded in transparent gelatinous caps7ules and contained 775 eggs (range 513-1231).A Spanish-language species account can be found at the website of Instituto Nacional de Biodiversidad (INBio) (http://darnis.inbio.ac.cr/FMPro?-DB=UBIpub.fp3&-lay=WebAll&-Format=/ubi/detail.html&-Op=bw&id=4205&-Find).
