The Atlas of Breeding Birds in the City of Milan (2009-2024)

The grid cell identifier is provided in the field “locationID”. The dataset was used to realise distribution maps for "The Atlas of Breeding Birds in the City of Milan", which will be published by the Milano University Press and will be available in Open Access at doi.org/10.54103/milanoup.306 (Nova et al. 2026). The dataset includes all records for 80 confirmed breeding species, and each record has an associated breeding code (field “eventRemarks”) (the highest breeding evidence recorded for a given species in a given month/year combination in each grid cell).

The dataset further includes occurrences for 10 native species that have been recorded during the breeding season in the city of Milano and may potentially breed there but lack breeding evidence, as well as for 6 non-established, non-native species. For non-breeding native species, occurrences recorded during the non-breeding period are also provided for comparison, and the field “eventRemarks” hence provides details on whether a given occurrence record belongs to the “breeding” or the “non-breeding” period.
