The interesting ornithological observation carried out by Italian birdwatchers has once again highlighted the importance of remote reading of the colored rings that are placed on the tarsus of species that are very difficult to capture. This is the case of a specimen of the Common Gull that in the summer of last year was observed and photographed in Domaso (CO) with a red ring and white writing H30K. Going back to the data communicated by ISPRA, it was discovered that the Seagull was ringed by pullus on 2 June 2012 in Rétszilas (Örspuszta) (Fejer), Hungary. From here the bird left and arrived in Molfetta (BA) where it spent the winter 2012-13, precisely from December 17th to March 9th. Then it appears in Domaso on 9 August 2013 and finally goes to winter again in Molfetta from 30 November to 12 December 2013.
These are important observations which describe the movements of some individuals, broadly underlining their phenology. It is therefore advisable for everyone to be very careful when observing large species because their tarsus could be the story of their life.
