Nonetheless, there is a critical knowledge gap in their trend and population status. We present an uninterrupted 47 years-long dataset of the breeding populations of 12 species of colonial waterbirds (Ardeidae, Phalacrocoracidae, Plataleidae, Threskiornitidae) throughout a 58,000 km 2 agricultural region in the higher Po basin (NW Italy). A trained team of collaborators censused with standardized field techniques the number of nests of each species at 419 colonies in the 1972-2018 period, summing up a total of 236,316 records. Data cleaning and standardization were performed for each census year, ensuring robust and consistent data. this dataset is among the largest ever collected for a guild of European vertebrates. It has already been used to describe the factors influencing population trends, and still offers opportunities to explore a wide range of key ecological processes such as biological invasions, global change consequences and biodiversity impact of agricultural practices.

We show here for the first time in form of check-list the phenological situation of the birds of Cremona province updated to 31.12.94, built up in the last 10-20 years by local amatorial birdwatchers who consulted also some historical publications on the subject with data from 1850 about and other data from most recently publications.
The species which proved to invalve in different degrees our province are 295, belonging to 18 orders and 59 families (rejected species are 12) . Breeding species are 103 including irregular ones but not the doubtful ones as such, the wintering species are 101, strictly regular migrants are 64, the accidental are 50.
