    Sicilian ornithological report 2021 (Sicily, Italy)
    https://doi.org/10.31396/Biodiv.Jour.2024.15.3.713.730

    ABSTRACT
    Useful documents such as Ornithological Reports are no longer published, although these types of publications help us to evaluate population trends: the IUCN status of each species is influenced by this kind documentations, and they are useful also to improve knowledge on migratory movements and, generally, on animal ecology. A report often collects also information from citizens: involving citizens in science projects has a strong positive response on their lives and their sensitivity to environmental issues. Given this importance, it seemed reasonable to us to work on a report which includes all the most important observations of birds of 2021. The importance rank was evaluated on the basis of the number of individuals or their unusual phenology. Every year, a high number of observations of wild animals are reported in several social media. These observations/records are lost if no one collects, validates and publishes them. All the data we present have been collected either from several digital channels of information, such as Ornitho, Ubird, eBird, INaturalist, Facebook groups, Trektellen.org or directly from birdwatchers. They include noteworthy observations about 185 species observed in Sicily during the year 2021 and, in addition, 109 species listed in a separate table because of fragmented or useless information.

    Checklist Odonata of Wetlands in south-western Sicily (Italy): Pantano Leone, Capo Feto, Margi Spanò, Nespolilla and Milo
    https://doi.org/10.31396/Biodiv.Jour.2024.15.2.391.397

    ABSTRACT
    Over time, the significance of checklists as essential tools for managing Sicily’s natural heritage has been underscored by the requirements outlined in international biodiversity conventions, particularly in relation to implementing the Habitats Directive. Compiling and updating checklists of fauna and flora for each specific region is necessary due to the growing interest in biodiversity today, which serves as a foundational and indispensable knowledge base. In this paper, a first detailed and complete checklist of the 17 Odonata species of some naturalistic areas of Sicily (Italy) is presented. Regarding the Capo Feto and Margi Spanò wetland, the checklist includes 10 species of dragonflies, 13 species for Margi Milo. As far as the Pantano Leone wetland is concerned 13 species of dragonflies are listed.

    An updated estimate of the wintering population of Sanderling Calidris alba (J.F. Gmelin, 1788) in Sicily for the years 2015-2022
    https://doi.org/10.31396/Biodiv.Jour.2024.15.2.301.309

    ABSTRACT
    The Sanderling Calidris alba (J.F. Gmelin, 1788) overwinters along the sandy coasts of Italy with an average of about 546 individuals for the years 2006–2010, showing a positive long-term increase. The species regularly overwinters in Sicily, for which the latest estimate reports 30–130 individuals in the years 2000–2004. Since no further updated estimates are available, new data were collected every winter on the field during the years 2015–2022, monitoring the most suitable stretches of beaches and collecting additional data from birdwatchers and photographers. A wintering regional population with an average of 100 individuals per year (65–136) was recorded, with an estimate of 145 individuals per year (110–180). The sandy coast of the Gulf of Gela hosts 54% of the recorded regional wintering population and about 10% of the whole Italian population and can therefore be considered a “site of national importance”. Other important areas are the Gulf of Catania, which hosts 24% of the regional population and 4.57% of the Italian population, and some sandy coasts of Ragusa’s province. This survey shows an increase of the regional wintering population in the last decades, highlighting Sicily’s role at national level for the wintering of the species. Conservation measures and sustainable management of Sicilian sandy coasts are strongly recommended to support the wintering of C. alba and other species of shorebirds.

    Colonies of herons and other allied waterbirds breeding in Sicily, 2007-2022
    https://doi.org/10.31396/Biodiv.Jour.2024.15.2.277.300

    ABSTRACT
    We describe the results of the first regional census of herons and other colonial waterbirds, including Great Cormorants Phalacrocorax carbo, Little Bitterns Ixobrychus minutus, Black-crowned Night Herons Nycticorax nycticorax, Squacco Herons Ardeola ralloides, Western Cattle Herons Bubulcus ibis, Grey Herons Ardea cinerea, Purple Herons Ardea purpurea and Little Egrets Egretta garzetta, carried out throughout Sicily from 2007 to 2022. We also collected data about Great Egrets Casmerodius alba and other waterbird species in Ardeidae colonies without any breeding evidence, as Eurasian Spoonbills Platalea leucorodia and Glossy Ibis Plegadis falcinellus. Collected data highlighted a regional widespread increase of the numbers in known colonies and nests of each species, especially of Bubulcus ibis that showed a sharp increase in number from 30 nests recorded for the whole region in 2007 up to 530 nests in 2022, mainly concentrated in eastern Sicily, in the province of Catania. Also A. ralloides, N. nycticorax and E. garzetta showed a positive trend with an increase in the number of colonized locations and nests recorded, with A. ralloides occupying the most of the Sicilian colonies with at least few pairs. On the other hand, A. cinerea showed a slight negative trend, with 45 nests recorded in 2007 and only 31 in 2022, at the end of the study; A. purpurea is an irregular breeder with an oscillating and unpredictable trend related to only 1–4 ascertained pairs maximum for the whole region. Despite the P. carbo is a regular breeding species in Sicily, it has not showed any sign of expansion in the last decade, remaining confined to a few historical locations near the Simeto River and Lentini Lake. All data here presented are related to the minimum and ascertained numbers of colonies and counted nests. Small colonies may not have been counted in some unmonitored locations, often inaccessible. It is highly recommended, in the near future, the creation of a coordinated survey network that would improve and make the census more in-depth and better standardized.

    Current status and expansion of Western Red-rumped Swallow Cecropis daurica rufula (Temminck, 1835) (Aves Hirundinidae) in Sicily
    https://doi.org/10.31396/Biodiv.Jour.2024.15.2.265.269

    ABSTRACT
    The recent paper published by Corso et al. (2021) about the status of the Western Redrumped Swallow, Cecropis daurica rufula (Temminck, 1835) (Aves Hirundinidae), in Sicily was mainly focused on updating the distribution of breeding pairs in the south-eastern part of the region; hence the decision to provide a more complete and up-to-date regional picture of the current status of this species collecting unpublished data and investigating the most suitable locations in the period 2011–2022. This survey highlights as, also in western and central Sicily, the species has been showing an increase in number of breeding pairs, found in 18 new UTM squares (11 of these for which the breeding was ascertained and 7 for which was very probable) in comparison to the last updated data. A new map of the distribution of the Western Red-rumped Swallow in Sicily is therefore presented here.

    Checklist Birds of Wetlands in south-western Sicily (Italy): Capo Feto and Pantano Leone
    https://doi.org/10.31396/Biodiv.Jour.2024.15.2.235.249

    ABSTRACT
    Over the years the importance of checklists as indispensable basic knowledge instruments in the correct management of Sicily’s natural heritage has been reinforced by the requests contained in international conventions on biodiversity especially by the need to implement the Habitats Directive. Today’s growing interest in biodiversity makes it essential that inventories of fauna and flora are compiled and kept up to date for each individual region to serve as an initial, indispensable knowledge base. In this paper, a first detailed (and, partly, commented) checklist of the waterbirds, diurnal raptors species of two naturalistic areas in Sicily (Italy) is presented. Regarding the Capo Feto (Mazara del Vallo) wetland, the checklist includes 94 species of waterbirds and birds of prey, As far as the Pantano Leone (Campobello di Mazara) wetland is concerned, the checklist includes 73 species of waterbirds. Capo Feto is a nationally important site for the Kentish Plover, an endangered species (EN) on the IUCN Red List of Threatened Species that nests there. Pantano Leone is a nationally important site for the overwintering of Common snipe.

    Update of the Leatherback sea turtle Dermochelys coriacea (Vandelli, 1761) and Green turtle Chelonia mydas (Linnaeus, 1758) observations in Italy (Reptilia Testudines)
    https://doi.org/10.31396/Biodiv.Jour.2023.14.4.851.865

    ABSTRACT
    In this work, we collected records since 2002 of Leatherback sea turtle Dermochelys coriacea (Vandelli, 1761) and since 2009 of Green turtle Chelonia mydas (Linnaeus, 1758). These observations have been made using scientific literature, citizen science programs, and social networks as data sources (Reptilia Testudines: Dermochelyidae and Cheloniidae). The aim of this work is to create a complete and up-to-date dataset. About one fifth of these new records comes from Facebook groups dedicated to biodiversity, thus underlining the usefulness of unconventional sources to gather data on species with poorly known distributions.

    Tiger beetles of Sicily (Coleoptera Cicindelidae)
    https://doi.org/10.31396/Biodiv.Jour.2023.14.4.791.849

    ABSTRACT
    Tiger beetles (Coleoptera Cicindelidae) are predators, both in the larval and adult state and each species tends to be specialized within a narrow habitat. For this reason, tiger beetles are excellent indicators of the quality of the biotopes in which they live and of the possible degradation of said biotopes due to anthropic actions. Currently, the populations of Cicindelidae are declining almost all over the world due to the destruction of the environments in which they live. In the Euro-Mediterranean area, including Italy, Cicindelidae mainly live in sandy environments like beaches, river mouths, the edges of lagoons and dune, and backdune ponds. Few species live on rocky coasts, in inland locations or in environments far from water such as paths and forest clearings. From what has been said, the coastal environments generally preferred by Cicindelidae are precisely those which in Italy, and also in Sicily, have undergone the greatest alteration and, often, destruction by man and his activities. In Sicily the Cicindelidae have always been studied since the first regional catalogs of the 19th century and other works were carried out in the following years, up to the present day. In the last decade, numerous reports have spread on the web, in numerous online chats, nature forums, etc. The aim of this work is to summarize and improve in a catalog what is known so far about the Sicilian Cicindelidae to highlight their peculiar systematic, ecological and geographical characteristics also in relation to the environment in which they live.

    ABSTRACT
    Cicindela (Cicindela) campestris didyme n. ssp. from the islands of Salina and Lipari (Aeolian Archipelago, Sicily, Italy) is here described. The new subspecies differs from other Italian populations of C. campestris, in particular from the closest ones of Sicily (C. campestris siculorum Schilder, 1953) and Calabria (C. campestris calabrica Mandl, 1944) for some morphological characters such as the shape of the clypeus, the granules of the elytra less elevated and more sparse and the different aedeagus. It is immediately recognizable by more or less extensively green-brown color of the dorsal surface often entirely red-brown.

    Past and current distribution of Charaxes jasius jasius (Linnaeus, 1767) (Lepidoptera Nymphalidae) in Sicily in relation to its host plant, Arbutus unedo L. (Ericaceae)
    https://doi.org/10.31396/Biodiv.Jour.2022.13.4.955.967

    ABSTRACT
    The authors provide an updated overview of the past and present regional distribution of the two-tailed Pasha Charaxes jasius jasius (Linnaeus, 1767) (Lepidoptera Nymphalidae) and its host plant, the strawberry tree Arbutus unedo L. Most of the occurrence data reported in the entomological literature was confirmed, and several new populations have been recently discovered. The distribution pattern of the insect and its host plant overlap almost perfectly. C. jasius jasius is more abundant and forms large and stable populations on the Peloritani Mts. and in some areas of the Madonie Mountains. The high number of new records of C. jasius jasius suggests that the species is experiencing a spreading phase, but the reasons behind this trend are still unexplained and need further field research and monitoring activities. The recent increase of its populations may depend on the current protection of many forest and pre-forest communities hosting the strawberry trees.

    New data on Calomera panormitana panormitana (Ragusa, 1906) in Sicily (Coleoptera Cicindelidae)
    https://doi.org/10.31396/Biodiv.Jour.2021.12.4.1027.1034

    ABSTRACT
    Calomera panormitana panormitana (Ragusa, 1906) (Coleoptera Cicindelidae) is an endemic species of Sicily, of remarkable biogeographic and ecological importance. It belongs to a small group of species of eastern Mediterranean distribution and it is peculiar for living on the low rocky coasts, near the sea. In this paper we provide new and summarized data on the presence of this species in Sicily. We examined its habitat, ecology and phenology in detail, and we provide useful elements for a better protection. In particular, the presence of this species also in some small islands, located at a short distance from the coast, highlights the presence of important refuge areas to be protected and promoted.

    ABSTRACT
    For the first time, the nesting of Eurasian crag martin Ptyonoprogne rupestris (Scopoli, 1769) (Passeriformes Hirundinidae) and Little egret Egretta garzetta (Linnaeus, 1766) (Pelecaniformes Ardeidae) in the Aegadian Islands (W-Sicily, Italy) is reported. Of particular interest is the nesting of the Little egret on the island of Maraone resulting in the first report for Sicily of a heronry on a marine island. Although this nesting environment has already been established in Sardinia, it should be emphasized that until now the establishment of a heronry has never been detected on an islet so far from the mainland.

    One hundred and fifty years of ornithology in Sicily, with an unknown manuscript by Joseph Whitaker
    https://doi.org/10.31396/Biodiv.Jour.2021.12.1.27.89

    ABSTRACT
    A new complete check-list of Birds of Sicily is presented in this paper, with a comparison with previous lists for a period of one hundred and fifty years. Further, an unknown manuscript by Joseph Whitaker “Birds of Sicily”, dated back to ca. 1920, has been transcribed and is here presented integrally. Thus, lists of birds here presented have been separated as follows: i) Doderlein (1869–1874); ii) Whitaker (1920); iii) Iapichino & Massa (1989), Lo Valvo et al. (1993) iv) Corso (2005), Ientile & Massa (2008); v) 2010–2020: Massa et al. (2015) and personal observations; vi) long-term trend: personal observations. Overall, 437 species are listed. Out of 283 species regularly present in Sicily, over the long period here considered of one hundred and fifty years, 75 (26.5) resulted to maintain stable populations, 35 (12.4%) resulted increasing, 12 (4.2%) very increasing, 75 (26.5%) with declining populations, 34 (12%) with very declining populations and 11 (3.9%) became extinct. Further, 41 species (14.5%) showed a population trend different from the previous ones, that we classified as fluctuating. We discuss about seventy representatives of the previous categories.
