“…In recent decades, the Iberian Peninsula has been successfully colonized by other African bird species, such as White-rumped Swift (del Junco & Gonz alez 1969), Black-shouldered Kite (Ferrero 1996), Little Swift (Ram ırez et al 2002) and Common Bulbul Pycnonotus barbatus, which has been breeding in this region since 2013. More recently, there have been an increasing number of records of other species, such as Ruppell's Vulture, Lanner Falcon Falco biarmicus, Cream-coloured Courser Cursorius cursor and Moussier's Redstart Phoenicurus moussieri.…”

“…Other species have become regular visitors, such as Rüppell's Vulture Gyps rueppellii (Ramírez et al . ); 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 , , , , , Dies et al .…”

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.

“…However, in spite of these population declines, the number of Rüppell's Griffons seen in the Iberian Peninsula is increasing (De Juana 2006, Gutiérrez et al 2010. These contrary situations indicate that a range of factors is very likely to be responsible, and it has been suggested that the influence of global climate change should be investigated (Ramírez et al 2011).…”

“…These changes are putting into contact two faunas in the European part of the Strait of Gibraltar, entailing changes in communities that are leading to new ecological interactions in this region 35 . The southern part of the Iberian Peninsula is a suitable place for colonization by different African bird species 36 , for which it is beginning to act as a focal point in the colonization of Europe 2,37 . In order to forecast these distribution ranges, more information is needed on whether these species are expanding or shifting their distributions, the spatial and temporal disequilibrium between the species ranges and their climatic favourability, the latitudinal rate of their change in distribution range, and whether these rates are expected to increase, decrease or remain constant in the future.…”

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.
