Salvatore Surdo, Auteur ; Paolo Galasso, Auteur ; Camillo Cusimano, Auteur ; Marco Reale, Auteur ; Manuel Andrea Zafarana, AuteurCitizen science can represent an effective tool for large-scale data collection and can be used to improve scientific knowledge and define species distribution ranges before proper planning of related conservation strategies. A regional census o[...]Article
Juan Arizaga, Auteur ; Arine Crespo, Auteur ; Agurtzane Iraeta, AuteurVolunteer-based (i.e., citizen science) monitoring schemes constitute a basic piece for the long-term monitoring of bird populations. This work aims to determine whether we can reduce the sampling effort, in terms of number of sampling journeys [...]Article
Nicolas Martinez, Auteur ; Guy M. Kirwan, Auteur ; Manuel Schweizer, AuteurContact zones with hybridization are documented for several Palearctic bird taxa. However, their extent is still poorly understood in many cases, including the Common Redstart Phoenicurus phoenicurus. Nominate P. p. phoenicurus breeds across mos[...]Article
Abigail M. Searfoss, Auteur ; Wan-Chun Liu, Auteur ; Nicole Creanza, AuteurPrevious studies have revealed diel patterns in the songs of Chipping Sparrows (Spizella passerina), with songs shorter in duration before dawn than after. However, the extent to which this phenomenon generalizes to the full geographic range of [...]Article
Quentin Groom, Auteur ; Lauren Weatherdon, Auteur ; Ilse R. Geijzendorffer, AuteurThere is a high demand for biodiversity observation data to inform conservation and environmental policy, and citizen scientists generate the vast majority of terrestrial biodiversity observations. As this work is voluntary, many people assume t[...]Article
Stuart E. Newson, Auteur ; Nick J. Moran, Auteur ; Andy J. Musgrove, Auteur ; James W. Pearce-Higgins, Auteur ; Simon Gillings, Auteur ; Philip W. Atkinson, Auteur ; Ryan Miller, Auteur ; Mark J. Grantham, Auteur ; Stephen R. Baillie, AuteurThe timing of migration is one of the key life-history parameters of migratory birds. It is expected to be under strong selection, to be sensitive to changing environmental conditions and to have implications for population dynamics. However, mo[...]Article
Michael Brooks, Auteur ; Sanjo Rose, Auteur ; Res Altwegg, Auteur ; Alan TK Lee, Auteur ; Henk Nel, Auteur ; Ulf Ottosson, Auteur ; Ernst Retief, Auteur ; Chevonne Reynolds, Auteur ; Peter G Ryan, Auteur ; Sidney Shema, Auteur ; Talatu Tende, Auteur ; Les G Underhill, Auteur ; Robert L Thomson, AuteurThe African Bird Atlas Project (ABAP) is a citizen-science bird-monitoring programme that relies on a robust, repeatable protocol (BirdMap) and allows insights into the distributions of African birds and their conservation. The protocol involves[...]Article
Lucas M. Leveau, Auteur ; Fabricio C. Gorleri, Auteur ; Ignacio Roesler, Auteur ; Francisco González-Táboas, AuteurRaptor communities are negatively impacted by urbanization. However, some species can thrive in urban areas. Raptor species traits that favour their presence in urban areas have been scarcely studied. Moreover, phylogenetic relatedness may be a [...]Article
Rafael Dantas Lima, Auteur ; Alexander Charles Lees, AuteurThe White-naped Xenopsaris Xenopsaris albinucha is an uncommon suboscine passerine with a disjunct distribution extending from Venezuela to the Southern Cone of South America. The ornithological literature concerning this species contains contra[...]Article
David L. Swanson, Auteur ; Reza Goljani Amirkhiz, AuteurAnecdotal observations of mid-summer arrival of Blue Grosbeaks (Passerina caerulea) in South Dakota, in the northern portion of their breeding range, suggest that this species may show a pattern of arrival at the northern breeding grounds that d[...]Article
Karine Princé, Auteur ; Paul Rouveyrol, Auteur ; Vincent Pellissier, Auteur ; Julien Touroult, Auteur ; Frédéric Jiguet, AuteurThe Natura 2000 protected area network (N2000), implemented under the Birds and Habitats Directives (respectively, Special Protection Areas, SPA, and Special Areas of Conservation, SAC), constitutes a key tool for the conservation of European bi[...]Article
Juan I. Areta, Auteur ; Matias A. Juhant, AuteurThe migratory Rufous-thighed Kite Harpagus diodon is widely distributed in South America, and a recent spatiotemporal analysis of its distribution that was largely based on citizen science data concluded that it breeds (almost) exclusively in th[...]Article
Corey T. Callaghan, Auteur ; Dale E. Gawlik, AuteurOne of the world's largest citizen science projects is eBird, a database that has been used primarily to address questions of bird distributions and abundance over large spatial scales. However, addressing finer-scale questions is also possible,[...]Thèse
Les espoirs de stopper la crise actuelle de biodiversité reposent principalement sur les aires protégées, qui visent à écarter ou restreindre les activités humaines de ces sites. Malgré le rôle central que jouent les aires protégées dans les str[...]Article
Francisco Cervantes, Auteur ; Marlei Martins, Auteur ; Robert E. Simmons, AuteurAs the demand for carbon-neutral energy sources increases, so does the need to understand the impacts that these technologies have on the environment. Here, we assess the potential consequences of additional mortality on an Endangered raptor rec[...]Article
Breanna F. Powers, Auteur ; Jason M. Winiarski, Auteur ; Juan M. Requena-Mullor, Auteur ; Julie A. Heath, AuteurIn migratory birds, among- and within-species heterogeneity in response to climate change may be attributed to differences in migration distance and environmental cues that affect timing of arrival at breeding grounds. We used eBird observations[...]Article
Giorgi Iankoshvili, Auteur ; David Tarkhnishvili, AuteurTwentytwo snake species are recorded for Georgia. Over three years (2017–2019), social media (Facebook, iNaturalist and Instagram) was inspected to identify new snake records for Georgia. This led to an increase in the total number of known snak[...]Article
Adam Zbyryt, Auteur ; Peter Mikula, Auteur ; Michał Ciach, Auteur ; Federico Morelli, Auteur ; Piotr Tryjanowski, AuteurDans Ibis (163(2) 2021)Birds with plumage colour aberrations are of interest to both the general public and scientists. However, due to their rarity in nature, information on the presence of colour aberrations is rarely found in the peer-reviewed literature. Explorati[...]Article
Christopher J. W. McClure, Auteur ; Brian W. Rolek, Auteur ; Gregory W. Grove, Auteur ; Todd E. Katzner, AuteurDans Ibis (163(2) 2021)Globally, evaluation of population trends is the most pressing research need for many species of conservation concern. Road counts for birds of prey are useful for monitoring long-term population trends and examining year-to-year variations in a[...]Article
Elie Gaget, Auteur ; Thomas Galewski, Auteur ; Frédéric Jiguet, Auteur ; Isabelle Le Viol, AuteurClimate change is one of the strongest biodiversity threats. Worse still, the impact of multiple anthropic stressors on species dynamics could complicate adaptation to temperature increase. International conservation policies aim to protect ecos[...]Article
Anina Coetzee, Auteur ; Phoebe Barnard, Auteur ; Anton Pauw, AuteurBiological communities are increasingly faced with novel urban habitats and their response may depend on a combination of biological and habitat traits. The response of pollinator species to urban habitats are of particular importance because al[...]Article
Evgeny A. Bragin, Auteur ; Alexander E. Bragin, Auteur ; Todd E. Katzner, AuteurDans Ibis (159(4) 2017)Nestbox programmes are frequently implemented for the conservation of cavity-nesting birds, but their effectiveness is rarely evaluated in comparison with birds not using nestboxes.
