Rivista Italiana di Ornitologia 2019-08-23T19:53:43+02:00 Emanuela Fusinato Open Journal Systems <p>The scientific journal <strong>Rivista Italiana di Ornitologia - Research in Ornithology (RIO)</strong> publishes original articles and short notes covering all major topics of ornithology twice yearly. The RIO was founded in 1911 by Ettore Arrigoni degli Oddi (1867–1942), Filippo Cavazza (1886–1953), Francesco Chigi (1881–1953), Alessandro Ghigi (1875–1970), Giacinto Martorelli (1855–1917) and Tommaso Salvadori (1835–1923). The first series ended its publication run in 1925, but the journal was revived as a second series in 1931, under the directorship of Arrigoni degli Oddi. In 1933, Edgardo Moltoni (1896–1980) took over as RIO Editor and became its owner and publisher up to his death. The Italian Society of Natural Sciences (Società Italiana di Scienze Naturali) then took over ownership of the RIO in 1981, publishing it in collaboration with the Museum of Natural History of Milan (Museo di Storia Naturale di Milano).</p> <p><br>This journal does not apply charge for publication to Authors as it is supported by institutional funds.</p> <p><br> The <strong>Rivista Italiana di Ornitologia</strong> is available as library exchange: <a href=""></a></p> XX CIO - Convegno italiano di ornitologia 2019-08-23T19:53:35+02:00 the Editors <p>NA</p> 2019-06-19T11:28:37+02:00 ##submission.copyrightStatement## [Waders and seabirds (Charadriiformes) nesting along the north-eastern Adriatic coastline (Veneto and Friuli-Venezia Giulia) in 2008-2014: abundance, trends and major conservation issues] 2019-08-23T19:53:38+02:00 Francesco Scarton Emiliano Verza Carlo Guzzon Paolo Utmar Giacomo Sgorlon Roberto Valle <p>[In 2008-2014 wader and seabird nesting pairs were censused along the 220-km long coastline of the NE Adriatic Sea, in the Veneto and Friuli-Venezia Giulia regions (NE Italy). Fourteen species were regularly breeding, with an annual mean of 20,610 pairs (±1553, 1 SD). The most abundant species was the Yellow-legged Gull (about 13,400 pairs on average, 65% of the whole population of the study area), followed by the Common Tern (1670 pairs, 8.1%) and Common Redshank (1525 pairs, 7.4%). The whole population of waders and seabirds increased with an annual rate, estimated with the TRIM software, of +0.8%, with a greater increase (+4.3%) if the Yellow-legged Gull was not included. Twelve species were stable or increasing; only the yellow-legged gull (-1%) and the common redshank (-2.4%) were decreasing. The populations of several species exceed 10% of those estimated for the whole of Italy; those of the Eurasian Oystercatcher, Common Redshank and Sandwich Tern are among the most important in the whole Mediterranean. On average, about 8860 pairs (43%) nest in the Venice lagoon, 6,400 pairs (31%) in the Po Delta, 5100 pairs (25%) in the Friuli-Venezia Giulia lagoons. Among nesting habitats, semi-natural (such as the fish farms) and man-made sites (dredge islands) make each year about 70% of the nesting pairs. Saltmarsh islets host large numbers of Common Redshank and Sandwich Tern, while along the beach zone the only abundant species are the Yellow-legged Gull and the Eurasian Oystercatcher. The major conservation threats observed in the study area were the erosion of littoral islands, the uncontrolled occurrence of sunbathers along the beaches, the vegetation overgrowth at dredge islands, the increasing frequency of saltmarsh submersion by high tides, the strong fluctuations of water levels inside the fish farms.]</p> <p>[Article in Italian]</p> 2019-06-18T00:00:00+02:00 ##submission.copyrightStatement## [Columba livia domestic breed, invasive entity also alien for Italy] 2019-08-23T19:53:43+02:00 Giovanni Boano Fabio Perco Marco Pavia Natale Emilio Baldaccini <p>[The Rock Dove (<em>Columba livia)</em> is a polytypic species originally confined to coastal and inland cliffs of western Palaearctic and northern Ethiopian regions and to those of Indian subcontinent. The present distribution is confused by extensions of range through hybridization with feral stock, which have determined its diffusion in geographical areas and environments that are very different and distant from the original ones, with a naturalized distribution now virtually cosmopolitan. Besides a substantial number of domestic breeds reared and maintained in this state, <em>Columba livia</em> is now represented by the original wild populations, generally in decline, and by feral populations, originated from abandoned or escaped domestic individuals. These populations developed above all, but no exclusively, in the cities, starting from the end of the XVIII century, with a further significant increase during the second post-war period, In this work, after having examined and discussed the distribution of the species resulting from the Pleistocene fossil findings and from the historical ornithological literature, we advance the hypothesis that wherever there are free-living populations showing phenotypic, biometric or genetic characteristics different from the wild morphotype, it is legitimate to consider these populations as an alien complex of domestic origin, to be controlled by culling and, when possible, eradicated. On the side-lines of this work, the Authors hope for a reconsideration of Italian names of this species.]</p> <p>[Article in Italian]</p> 2019-06-18T00:00:00+02:00 ##submission.copyrightStatement## Birds of the Entella river (Genoa, Italy): a qualitative assessment of bird diversity in an urbanizing biotope, with implications for management and conservation 2019-08-23T19:53:42+02:00 Andrea Simoncini Daniela Papi Enrico Ruggeri <p>This work presents the first assessment of the birds of the Entella river (Genoa, Liguria), a small wetland embedded in an urbanized matrix. Data were collected through standardized in situ censuses from April 2012 to June 2017 and integrated with historical and recent data from other verified sources. A total of 278 species are known from the site; 53 species (19.06%) breed in the area, whereas 62 (22.30%) species are vagrant and 81 species (29.14%) are included in the Annex I of the Birds Directive (79/409/CEE). We determined the following indices: NP/P ratio = 1.48, O.V.I. (Ornithological Value Index) = 20.53. In-depth data are provided for vagrant species and for species of conservation concern, to prioritize conservation efforts. The results underline the importance of the Entella river as a local biodiversity hotspot and suggest a possible role of the area as a stepping stone in the regional ecological network. The study highlights a dichotomy between urbanization and high bird diversity in the area and acts as a first step towards its conservation and implementation.</p> 2019-06-18T00:00:00+02:00 ##submission.copyrightStatement## Breeding bird communities in an area of the Northern Apennines (Piedmont, NW Italy) 2019-08-23T19:53:39+02:00 Franco Carpegna Giovanni Soldato Roberto Toffoli <p>During the Spring of 2011, we studied the bird community in an area of Val Borbera, in the province of Alessandria (NW Italy). In the study area, situated at an altitude between 655 and 1700 m a.s.l., we conducted 110 points count ten minutes each in four microhabitats (agricultural areas, shrubs, forests, and prairies). In total, we surveyed 72 species, of which 51 were passerine and 21 non passerine. The most abundant species were <em>Sylvia atricapilla,</em> <em>Phylloscopus collybita, Apus apus,</em> and <em>Turdus merula.</em> In the agricultural areas, we detected a total of 50 species (<em>Sylvia atricapilla, Parus major, Turdus merula</em> were the most abundant). In the shrubs, we detected 30 species (<em>Sylvia atricapilla, Parus major, Fringilla coelebs, Phylloscopus collybita, Turdus merula, Erithacus rubecula</em> were the most abundant). In the forest areas, we found 45 species (<em>Sylvia atricapilla, Parus major, Fringilla coelebs, Phylloscopus collybita, Turdus merula, Erithacus rubecula</em> were the most abundant), and in the prairies, we detected 48 species (<em>Alauda arvensis, Anthus campestris, Sylvia atricapilla, Turdus merula, Anthus trivialis, Sylvia communis</em> were the most abundant). Compared to the other macro habitats, the agricultural areas have a significantly high abundance and richness in species, which highlights the importance of the agricultural mosaics in the Piedmont and mountain areas. The data which has been collected so far confirms the important role of this area, given the presence of some species which are rare at a regional scale.</p> 2019-06-18T00:00:00+02:00 ##submission.copyrightStatement## [The Booted Eagle, Hieraaetus pennatus, wintering in Agrigento district] 2019-08-23T19:53:37+02:00 Giovanni Salvo <p>[Records reported on winter presence of Booted Eagle in Agrigento district.
