Article
Full-text available
Petrels are particularly sensitive to predation by introduced species. Many populations have reduced their breeding ranges, currently mainly occupying predator-free sites. Breeding range reduction leads to interspecific competition for nesting sites, which can be detrimental to petrels. Here, we evaluate how the presence of introduced mammals (cats...

Islands, and the particular organisms that populate them, have long fascinated biologists. Due to their isolation, islands offer unique opportunities to study the effect of neutral and adaptive mechanisms in determining genomic and phenotypical divergence. In the Canary Islands, an archipelago rich in endemics, the barn owl (Tyto alba), present in...
Article
Until the middle of the 20th century, the Common Raven Corvus corax was an abundant bird in the Canary Islands. However, during recent decades, populations have decreased dramatically in the most densely populated islands, apparently because of changes in land use and other anthropic activities. In the current study, we estimated raven population s...

The combined actions of climatic variations and landscape barriers shape the history of natural populations. When organisms follow their shifting niches, obstacles in the landscape can lead to the splitting of populations, on which evolution will then act independently. When two such populations are reunited, secondary contact occurs in a broad ran...
Article
Procellariiformes are one of the most threatened groups of birds of the world so knowledge of nesting habitat and factors affecting breeding rates are vital issues for their conservation. Although Cory's Shearwater Calonectris borealis is a well-studied seabird species on the whole, information on the relationship between its breeding parameters an...

Due to their life-history traits, the petrels are particularly sensitive to predation by introduced species. Therefore, many populations have constricted their original breeding distribution range, currently only occupying predator-free sites. In this scenario, interspecific competition for nesting sites can be detrimental for the petrel’ conservat...

Le Pigeon des lauriers Columba junoniae exploitant le pollen et le nectar de l’Agave américain Agave americana. Les observations ont été réalisées durant l’été 2019 sur l’île de Tenerife, dans une zone de transition entre la végétation thermophile et la forêt de lauriers. En étant perchées sur les fleurs ou la tige de l’ombelle, les oiseaux picorai...
Article
The Canary Islands are home to a large variety of endemic fauna. The Canary shrew (Crocidura canariensis) has a distribution restricted to Fuerteventura, Lanzarote and the islets of Lobos and Montaña Clara. One of the main threats to the insular fauna is the arrival of exotic species. The greater white-toothed shrew (Crocidura russula) is an easily...

During 2015 and 2016, we conducted the first systematic study of the size of the breeding population, distribution, habitat and diet of the Barbary Falcon Falco peregrinus pelegrinoides on La Palma, Canary Islands. We found a minimum of 28 territories (3.9 territories/100 km2) at an average distance of 3.6 km (range 1.7–7.7 km) from their nearest n...

Data
Falcons were detected by admissions to La Tahonilla Wildlife Rehabilitation Center, Cabildo de Tenerife (1998-2017), lost falcons reports issued by falconers to the Wildlife Rehabilitation Center (2007-2017), and field observations by authors (1993-2017). Territory: yes = holding territory. Paired : Yes = Mated, No = Unmated
Article
Peregrine Falcons (Falco peregrinus) on the Canary Islands are considered to be of the Barbary Falcon subspecies (F. p. pelegrinoides). Here we report on lost falconry birds present among the wild population of resident falcons, and provide rough approximations of their abundance for Tenerife, the largest island of the Canaries. We observed lost fa...

The specific spatial distribution and habitat association -strongly influenced by environmental factors or competitive interactions- are major issues in ecology and conservation. We located and georeferenced nesting sites of five cliff-nesting raptors (Egyptian vulture Neophron percnopterus, common buzzard Buteo buteo, osprey Pandion haliaetus, com...

Both ecology and biology of the peregrine falcon are well known throughout its range. However, excepting the data from the Canary Islands, knowledge on the Barbary falcon natural history is scarce. We studied four Barbary falcon nesting sites in South-western Iran between 2011 and 2014. All eyries were located in cavities of cliffs whose average he...

Uncovering the genetic basis of phenotypic variation and the population history under which it established is key to understand the trajectories along which local adaptation evolves. Here, we investigated the genetic basis and evolutionary history of a clinal plumage color polymorphism in European barn owls (Tyto alba). Our results suggest that bar...

The Teno range of mountains, located in the northwest Tenerife, Canary Islands, is still a refuge for the flora and fauna of the island. Until now, at least four native species of reptiles, 232 of birds (both breeding and migrant), and six mammals have been recorded for that site. For some of these animals, such as Canarian Spotted Lizard (Gallotia...

Between 2004 and 2007, we studied density, habitat features and breeding parameters of the osprey (Pandion haliaetus) population in Boa Vista Island (Cape Verde). A total of 79 nest structures were identified, 37 of which were occupied for at least 1 year during the study period. The osprey population ranged between 14 and 18 pairs, and the mean de...

We studied nesting habitat selection of the endangered non-migratory Osprey Pandion haliaetus population of the Canary Islands and evaluated the effect of human expansion in recent decades. Compared with randomly selected potential nest-sites, Osprey nests were more frequently found on taller, southwest-facing cliffs, char-acterized by lower human...

Territory spacing and breeding rates of an insular population (north-western Tenerife, Canary Islands) of Barbary Falcon Falco peregrinus pelegrinoides was studied from 1993 to 2008. The population increased constantly since the outset, from two pairs in 1993 to 12 in 2008. Mean density was 5.48 pairs per 100 km and mean nearest neighbour distance...

We studied the diet of the osprey Pandion haliaetus in the Canary Islands during 1997-2008 using prey remains under perches and nests, and direct observations. We collected data both in breeding territories and in non-breeding areas. We counted a minimum of 307 fish individuals as prey remains (both during breeding and non-breeding seasons), and id...

The taxonomic status of the Barbary Falcon has been controversial for many years, it being variously considered a subspecies of Peregrine Falcon (Falco peregrinus pelegrinoides) or treated as a full species (F. pelegrinoides). Although morphological and molecular studies are still scarce, they suggest that subspecific status is more appropriate. Ot...

We describe the adoption and alloparental care of fledglings by an Osprey pair during two consecutive breeding seasons (2008-09) in the small and semi-colonial cliff nesting population of Tenerife (Canary Islands). The intruding broods (two fledglings each year) switched nest a few days after fledging (≤ 10 days in 2008 and ≤ 6 in 2009). They used...

During the 2009 breeding season (February-June) we studied the population size of Common Raven on four islands of the Canarian archipelago. A total of 44 pairs were censused: ten in Gran Canaria, 12 in Tenerife, 17 in La Palma and five in La Gomera. Most of these pairs have their territories in ravines, gullies and sea cliffs, coinciding with or cl...

We report 21 new polymorphic microsatellite markers in the European barn owl (Tyto alba). The polymorphism of the reported markers was evaluated in a population situated in western Switzerland and in another from Tenerife, Canary Islands. The number of alleles per locus varies between two and 31, and expected heterozygosity per population ranges fr...
