[In order to contribute to the knowledge of the spatio-temporal progression of post-nuptial migration of birds across the Italian Alps, we present in detail the results of the analysis carried out for 69 species (4 non-Passeriformes; 65 Passeriformes) of the 191 ringed within the Progetto Alpi. Data were collected in 40 ringing stations located in different habitats and at different altitudes (mountain passes, slopes and valley floors) and active in the post-breeding migratory period (1 August - 30 November). Among these, those (n=15) with continuous activity (at least one month) and known sampling effort (daily capture effort described as product of net area in square meters by operating time in hours) were selected. Data from the 6 stations that operated continuously over the years (2001-2017) and with standardised capture effort were used for trend analyses. Species covered refer to those with more than 100 birds ringed within the first eight hours after sunrise (excluding local retraps). Species accounts contain detailed data from datasets from all stations participating in the Alps Project (1997-2017)].
