Il Club su Rivista Internazionale di Ornitologia
Finalmente il Lavoro scientifico – per il quale ci onora il nome tra gli Autori il Prof. P.Busse ( di certo uno tra i più prestigiosi Ornitologi in Europa e la Bird Migration Research Foundation – è pubblicato come in calce su Rivista Internazionale Scientifica ” The Ring” nell’annata 2018.
È stato un lavoro difficile e faticoso ma il traguardo è raggiunto a nome di tutto il Club e di quanti hanno collaborato alla raccolta dei dati .I nomi Cavina e Bucchi ci sono solo perchè hanno sistematizzato i dati numerici e sopratutto i dati raccolti da Rinaldo Bucchi nel Progetto Colombaccio sino al 2007 ,i soli disponibili per una seria valutazione statistica come è stata sviluppata dal Prof.Busse .
Il lavoro si chiude con il Ringraziamento a tutti i membri del Club che hanno collaborato
ACKNOWLEDGEMENTS
We would like to express our gratitude to all members/observers from Club Itali- ano Colombaccio. The data collection would not have been possible without their co- operation.

ABSTRACT
Cavina E., Bucchi R. and Busse P. 2018. The general pattern of seasonal dynamics of the autumn migration of the Wood Pigeon Columba palumbus in Italy. Ring 40: 3-18.
Given the scarcity of studies on the migration of the Wood Pigeon through Italy, the first systematic observations by a network of hunters, as citizen researchers, can be presented as a starting point for more in-depth analyses. Observations from the years 1998-2006 are analysed and presented in a generalized form. During this period more than 100 observation sites, covering most of Italy, were active for about 40 days every autumn. Migration over Italy was described in terms of the timing and intensity of migration. Special attention was directed to the long-term number dynamics and seasonal dynamics of the passage. The most intensive migration was observed within northern Italy, while lower intensity is visible more to the south of the peninsula. Following tendencies in numbers of observed migrants within the ten years of the study, we can find positive tendencies in most of the northern provinces, while three negative trends are visible in central Italy. The study of the seasonal pattern, in terms of the number dynamics of the passage and the frequency of pronounced peak days, strongly suggests that there are five or six waves of pigeons passing through Italy in different parts of the autumn that are quite stable between years. Every year the time of the passage includes a few peak days of migration.
