We identified 42\u2009260 calls, categorized into six distinct vocalization types: quaver, flat, varied, sustained, sweep, and scream. A supervised Random Forest algorithm mathematically validated these classifications with high accuracy (98.12%; Kappa\u2009=\u20090.96), identifying frequency modulation and spectral structure as the most informative parameters for discrimination. Preliminary analysis revealed daily activity peaks across the 24 h cycle. This preliminary study characterizes a complex vocal repertoire in three juvenile female W. cerradensis, addressing knowledge gaps in Neotropical rodent bioacoustics.<\/jats:p>","DOI":"10.1121\/10.0046922","type":"journal-article","created":{"date-parts":[[2026,10,20]],"date-time":"2026-10-20T12:45:02Z","timestamp":1792500302000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Acoustic repertoire and vocal activity of three juvenile female cerrado red-nosed mice,\n                    <i>Wiedomys cerradensis<\/i>\n                    (Rodentia: Cricetidae)"],"prefix":"10.1121","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1399-1953","authenticated-orcid":false,"given":"Hugo Eduardo","family":"Ferreira","sequence":"first","affiliation":[{"name":"Laboratory of Bioacoustics\/EcoAcoustic Research Hub, Centro de Bioci\u00eancias, Universidade Federal do Rio Grande do Norte , Av.
