Outlining Migratory Routes: Bird Ringing at Castelporziano
Ringing helps to follow birds in time and space during their migrations—find out where they are coming from and, eventually, where they are going.

In a rapidly changing world, information on the condition of wildlife is essential for taking the most appropriate conservation action.
Birds not only fascinate millions of people, but it is also possible, by studying them, to assess environmental health.

One of the methods of studying wild birds is scientific ringing, a research technique that enables birds tagged with a very light metal ring to be recognized individually and followed in time and space.
Each ringed bird can provide a great deal of information on its life and insight on its movements. Reverse reconstruction of flights enables the migration routes followed to be outlined, and preferred stopping areas to be identified.

Ringing is also an opportunity to gather other valuable information for studying these animals. For example, it has enabled standards to be defined for distinguishing adults from youngsters through wing, tail, and weight measurements.

Most knowledge about the migration of birds, and the effects of changes in climate and habitats on the composition of avian communities, is due to the work of ringers.

Above all, ringing means ensuring the safety of the birds during all phases of capture and tagging. Capture takes place by means of entirely harmless methods, generally using very fine and soft nylon thread nets that are almost invisible.

After capture, the animals are removed from the nets and placed in soft cotton bags, ideal for transporting them safely and taking them to a ringing station.

At the station, a very light metal ring is applied to the bird's leg, on which an alphanumeric code is embossed, which refers to an international coordination system.
The ring enables the individual bird to be recognized in the event of subsequent capture, and possibly for its migration to be followed.

Once ringed, the animal is set free to return to its activities. It will fly away carrying its little sign of recognition, the metal ring, on its leg.

During their long flights, migratory birds cross frontiers freely, belonging de facto to the entire international community. The creation of a network of ringing stations distributed throughout the world has been vital for gathering useful data for the protection of different species.

The Presidential Estate of Castelporziano ringing station came into being on the May 7, 1990.

In the fall, the return migrations begin of birds that arrived in the spring from Africa, which, after nesting, resume their journey, crossing the estate, as well.
During this period of the year, it is possible to catch and ring a very high number of birds for scientific purposes.

One of the species with a preference for the estate during the coldest season is the woodcock. The ringing activity carried out at Castelporziano has enabled numerous reports of recaptures of woodcocks to be gathered, in Italy and in Europe, including one carried out in Russia, on the border with Mongolia, over 2,170 miles (3,500 km) away.
One specimen was even recaptured on the estate 11 whole years after it was first caught. Much of the information gathered over the years has been used to assess the possible migratory routes of woodcocks, which come to the estate to spend the winter in a particularly hospitable place.

During migrations, many species of woodcock stop in places where they can rest and perhaps re-fuel before resuming their journey. Castelporziano is known to be one of these way-stations, preferred by numerous species, especially during the fall.

A fundamental part of the activities at Castelporziano is education. Thousands of young people, coming from schools all over Italy, are welcomed to the Estate every year. The young visitors have an opportunity to observe the various bird species up close and to assist the ringers during the catching, ringing, and freeing phases.

Direct participation is invaluable: it enables the cultural and conservation message put forward by the estate's ringers to be discovered and appreciated, and the importance of scientific ringing to be understood.
“Passion, knowledge, and love of nature leads Castelporziano ringers to share the wonderful experience that is ringing as much as possible. The concerned, curious, surprised, and enchanted looks of both children and adults make up for the cold, the rain, the fatigue, the waking up long before dawn that have marked our activity over the years. And if just one of those children develops a passion for nature, our work will have been successful.” The ringers of the Castelporziano Estate
