“…Other species have become regular visitors, such as R€ uppell's Vulture Gyps rueppellii (Ram ırez et al 2011); the most recent arrival is the African Long-legged Buzzard Buteo rufinus cirtensis. There has been a significant increase in the number of records of this bird in recent years, with a marked southerly bias in their distribution (de Juana 1997, 2002, 2005, 2006, Dies et al 2007, 2011, Guti errez et al 2012. In 2004, the African Long-legged Buzzard nested in Ceuta (Muñoz 2003, Avila et al 2004, one of the two Spanish cities in northern Morocco, and in 2009 it was confirmed that the species was breeding in mainland Spain and, therefore, continental Europe (Elorriaga & Muñoz 2010).…”

Winters have become warmer under the impact of climate change, which has modified the phenology as well as the distribution ranges of birds. The African Long‐legged Buzzard Buteo rufinus cirtensis has recently colonized Europe via the Strait of Gibraltar. We aim to explain the native distribution of this species and to predict favourable areas in newly colonized parts of Europe using geospatial modelling to identify the most influential factors in this process. We applied the favourability function, a generalized linear model describing environmental favourability, for the presence/absence of breeding areas in northern Morocco and the southern Iberian Peninsula, according to a set of variables describing climate, topography, human activity, vegetation and purely spatial trends. A model was built using some known breeding sites in northern Morocco, and was used to forecast future suitable breeding areas in Europe. A second model was built with the available data for northern Morocco and Europe to explain the current distribution of breeding sites. Both models were assessed according to discrimination, calibration and parsimony criteria, and the influence of each factor was analysed using variation partitioning. We conclude that the Iberian Peninsula could provide new suitable areas for the species and facilitate its northward expansion. This result, together with the increasing number of records available, suggests that this species could soon spread throughout Europe. Steady temperatures and abundant but seasonally distributed precipitation showed the strongest predictive power in the models. This indicates a close relationship between the species’ distribution and climate in the study area, and suggests that this species finds its most favourable environments in the Mediterranean biome. Topography and vegetation, specifically cliffs and woods near hunting zones, point to a fine‐scale habitat selection for breeding. As the case of the African Long‐legged Buzzard is not a unique event, our results may be useful to determine whether a northward expansion of the Mediterranean biome could be followed by distribution shifts of bird species that have so far been restricted to Africa.

“…Este hecho se ha confirmado con el registro de la gaviota con anilla C.A3A nacida en Kokkola (Finlandia), la cual fue observada los días 29 de octubre y uno de noviembre de 2016 en Espinho (Portugal) y posteriormente el 20 de enero de 2017 en Málaga (España). La estructura de edad de las aves invernantes en España anilladas en origen coincide con la descrita por Marques et al (2009) Hario (1990) indican que la gaviota báltica tiene una dieta mayoritariamente piscívora, algo que podría estar relacionado con su mayor abundancia en Málaga ya que se encuentra en una de las zonas con más productividad del Mediterráneo (Camiñas et al 2004 (Gutiérrez et al 2013). Lo que nos hace creer que si la subespecie nominal fuera igual de abundante en ellas también sería detectada en números similares.…”

La gaviota sombría, Larus fuscus (Linnaeus, 1758), es una especie politípica cuya situación taxonómica sigue siendo revisada por parte de algunos científicos. La subespecie nominal Larus fuscus fuscus o "gaviota báltica" está considerada rareza en España, aunque desde hace más de una década cada año es observado algún ejemplar anillado. Esto nos ha llevado a actualizar su distribución espacial y temporal en España, usando datos de aves cuyos registros han sido aprobados o están bajo revisión del Comité de Rarezas de la Sociedad Española de Ornitología. Nuestros resultados sugieren que España constituye un área de invernada para una parte muy pequeña de la población, especialmente el área de Má-laga, y que el período con mayor probabilidad de avistamientos es el de noviembre a marzo.Palabras clave: Gaviota sombría, Anilla de color, Subespecie, Rarezas, Anillamiento científico. Abstract New knowledge on the winter season and migration of Baltic gull Larus fuscus fuscus Linnaeus, 1758 (Charadriiformes: Laridae) in SpainThe Lesser black-backed gull, Larus fuscus (Linnaeus, 1758), is a polytypical species whose taxonomic status is still being reviewed by some scientists. The nominal subspecies Larus fuscus fuscus or Baltic gull is considered a rarity in Spain. However, during the decade every year some individuals are observed, fact that has led to update the existing information on its spatial and temporal distribution in Spain, using data of both, ringed birds and birds without ring approved and/or under consideration of the Rarity Committee of the Spanish Society of Ornithology. Our results suggest that Spain is a wintering area for a very small part of the population, especially Malaga area, and that the period with the highest probability of sightings is from November to March.

Fuzzy sets allow gaging the extent and rate of species range shift due to climate change

The recent modification of species distribution ranges in response to a warmer climate has constituted a major and generalized biogeographic change. The main driver of the shift in distribution is the disequilibrium of the species ranges with their climatic favourability. Most species distribution modelling approaches assume equilibrium of the distribution with the environment, which hinders their applicability to the analysis of this change. Using fuzzy set theory we assessed the response to climate change of a historically African species, the Atlas Long-legged Buzzard. With this approach we were able to quantify that the Buzzard’s distribution is in a latitudinal disequilibrium of the species distribution with the current climate of 4 km, which is driving the species range northwards at a speed of around 1.3 km/year, i.e., it takes 3 years for the species to occupy new climatically favourable areas. This speed is expected to decelerate to 0.5 km/year in 2060–2080.
