La Passata Ornithologic Station is a ringing center with scientific aim, conducted by a group of voluntary researchers authorized by the Italian National Institute for Wild Fauna and the Regione Lombardia (Lombard District), with the help of some interested friends. In 1996 it was declared  Leading Ornithologic Station of the Provincia di Bergamo (Province of Bergamo), with deliberation G.P. n° 1637 of the 5th of December, 1996.

Our Station is set in the area of Prealpi Bergamasche (North of Italy), at about 1000 m a.s.l., on a typical mountain pass interested by intens migrations during spring and autumn.

Our nets (mist-net) are 90 m long and reach a height of 5 m. Our activity began in October 1995 and lasts for about 100 days a year. Since the beginning to 2001 more than 39.000 birds have been ringed, from 93 different species.
Our activity of ringing allows to carry out some researches on migration and on migratory courses of the birds, where La Passata Ornithologic Station is directly involved in many levels, besides offering the opportunity of keeping classes and lectures on migration and birds biology.
