La sortida consistirà en una visita guiada a una bassa amb l’objectiu d’identificar les postes, el cant nupcial i les diferents espècies d’amfibis que es poden trobar a la comarca d’Osona. Les basses són punts calents de biodiversitat on a principis de primavera els amfibis es dirigeixen per iniciar els cants nupcials, aparellar-se i realitzar les postes. Aquesta concentració d’individus ens permet observar fàcilment, i en un mateix lloc, diferents espècies d’amfibis com; la reineta, el tòtil, el gripau corredor, el gripauet, el gripau d’esperons i el tritó palmat.
