The management of feral pigeon (C. livia var. domestica) populations in urban ecosystems represents both a long-standing issue, emerging after World War II, and a re-emerging challenge for many European cities. This study analyzes the population size and density of pigeons in the historic center of Padua, also investigating the reproductive dynamics at the dovecote observatory located near Porta Savonarola. Population estimates were conducted during the first four months of 2024 using the previously validated Overlapping Urban Layers (SUS) census method. Concurrently, quantitative data were collected, monitoring pigeon behaviors, nesting sites, and their interactions with the urban environment. The dovecote was monitored biweekly, recording the number of nests, eggs, and chicks. Additionally, a questionnaire was administered to 1 assess citizen awareness regarding pigeon management, gathering 39 responses via Google Forms. The results indicate a non-uniform distribution of pigeons, with an estimated 2261 individuals in the historic center and a density of 495 pigeons per km². Compared to previous surveys, a reduction in pigeon numbers was observed, suggesting a positive effect of the management measures adopted, although critical areas with high concentrations remain. A similar decline was observed in the monitoring of the dovecote, with an average of 92 nests/44 houses, 6 eggs, and 8 chicks recorded during the 8 surveys. The questionnaire was preliminarily validated and will be distributed on a larger scale with the support of the Municipality of Padua next fall. This study highlights the importance of integrated management strategies that combine population control methods with community awareness and engagement.
La gestione delle popolazioni di colombo (C. livia var. domestica) nell’ecosistema urbano rappresenta sia un’annosa questione, sorta durante il secondo dopoguerra, che una sfida ri emergente per molte città europee. Questo studio analizza la numerosità e la densità della popolazione colombacea nel centro storico della città di Padova, indagando anche le dinamiche riproduttive presso l’osservatorio della Torre colombaia situata vicino a Porta Savonarola. Le attività di stima della numerosità sono state condotte nel primo quadrimestre del 2024, utilizzando il metodo di censo degli Strati Urbani Sovrapposti (SUS), precedentemente validato. Contestualmente, sono stati raccolti dati quantitativi, monitorando i comportamenti, i siti di nidificazione e interazioni dei colombi con l'ambiente urbano. La Torre colombaia è stata monitorata bisettimanalmente, registrando nidi, uova e pulli presenti. Inoltre, è stato somministrato un questionario per valutare la consapevolezza dei cittadini riguardo alla gestione dei piccioni; raccogliendo 39 risposte tramite Google Forms. I risultati indicano una distribuzione non uniforme dei colombi, con una stima di 2261 individui nel centro storico e una densità di 495 piccioni per km2. Rispetto ai censimenti precedenti, si è osservata una riduzione nel numero di piccioni, suggerendo un effetto positivo delle misure di gestione adottate, anche se permangono aree critiche. Un calo analogo è stato riscontrato nel monitoraggio della Torre colombaia, con una registrazione di 92 nidi/44 casette, 6 uova e 8 pulli registrati durante gli 8 sopralluoghi. Il questionario è stato validato preliminarmente e sarà diffuso su larga scala con il supporto del Comune di Padova nel prossimo autunno. Questo studio evidenzia l'importanza di strategie di gestione integrate che combinano metodi di controllo della popolazione e sensibilizzazione della comunità.

Abstract
The management of feral pigeon (C. livia var. domestica) populations in urban ecosystems represents both a long-standing issue, emerging after World War II, and a re-emerging challenge for many European cities. This study analyzes the population size and density of pigeons in the historic center of Padua, also investigating the reproductive dynamics at the dovecote observatory located near Porta Savonarola. Population estimates were conducted during the first four months of 2024 using the previously validated Overlapping Urban Layers (SUS) census method. Concurrently, quantitative data were collected, monitoring pigeon behaviors, nesting sites, and their interactions with the urban environment. The dovecote was monitored biweekly, recording the number of nests, eggs, and chicks. Additionally, a questionnaire was administered to 1 assess citizen awareness regarding pigeon management, gathering 39 responses via Google Forms. The results indicate a non-uniform distribution of pigeons, with an estimated 2261 individuals in the historic center and a density of 495 pigeons per km². Compared to previous surveys, a reduction in pigeon numbers was observed, suggesting a positive effect of the management measures adopted, although critical areas with high concentrations remain. A similar decline was observed in the monitoring of the dovecote, with an average of 92 nests/44 houses, 6 eggs, and 8 chicks recorded during the 8 surveys. The questionnaire was preliminarily validated and will be distributed on a larger scale with the support of the Municipality of Padua next fall. This study highlights the importance of integrated management strategies that combine population control methods with community awareness and engagement.File | Dimensione | Formato | |
