Since 2004 we have performed a census of autumnal Passeriformes migrating over the Trevigiane Prealps area. For the assessment the visual count method was used. Among all data collected, we analyzed those regarding Hawfinch, Coccothraustes coccothraustes, a species easily monitored by its characteristic f light and vocalization. The monitoring was performed in two sites far away 39 kilometres: Mount Pizzoc (Fregona, Vittorio Veneto) and Forcella Mostaccin (Maser). During seven years of monitoring, we have observed strong variations of number of migrating hawfinches, but in the meantime we have improved the knowledge related to the migration of this species over these two important areas, now protected as mountain pass.
