Eduardo Garcia-Del-Rey, Auteur ; Luis Gil, Auteur ; Nikos Nanos, Auteur ; Unai Lopez-De-Heredia, Auteur ; Pascual Gil Munoz, Auteur ; Jose Maria Fernandez-Palacios, AuteurDans Bird Study (56 2009)Capsule Tree cover and seeds on the ground influence the occurrence of Blue Chaffinches during the non-breeding period. Aims To study the feeding habitat selection of the common Tenerife Blue Chaffinch race during the non-breeding period as a de[...]
Article
Eduardo Garcia-Del-Rey, AuteurThe Canary Blue Tit Cyanistes teneriffae has recently been split off from the Common Blue Tit Cyanistes caeruleus as a separate species. Live biometrics from across the entire distribution on the island of Tenerife (subspecies teneriffae tenerif[...]
Article
Eduardo Garcia-Del-Rey, Auteur ; Will Cresswell, AuteurWe describe the density, breeding and foraging ecology of the Berthelot's Pipit (Anthus berthelotii), an endemic passerine to the Atlantic islands, in the semi-arid coastal scrub of Tenerife. Furthermore, we analyse the effects of temperature an[...]
Article
Eduardo Garcia-Del-Rey, Auteur ; Guillermo Delgado, Auteur ; Javier Gonzalez, Auteur ; Michael Wink, AuteurWe have analyzed nucleotide sequences of the mitochondrial cytochrome b (cytb) and NADH dehydrogenase subunit 2 (nd2) genes to elucidate the phylogenetic status (genetic variation) of Canary Island populations of great spotted woodpeckers (Dendr[...]
Article
Javier Gonzalez, Auteur ; Michael Wink, Auteur ; Eduardo Garcia-Del-Rey, Auteur ; Guillermo Delgado Castro, AuteurWe obtained DNA sequence data from mitochondrial (cytochrome b) and nuclear genes (myoglobin and ornithine decarboxylase) to reconstruct the phylogenetic relationships among eight species of shrikes (Lanius). Phylogenetic analyses based on maxim[...]
Article
Eduardo Garcia-Del-Rey, Auteur ; Oddmund Kleven, Auteur ; Jan T. Lifjeld, AuteurBirds breeding on islands often exhibit lower rates of extrapair paternity than their mainland counterparts, perhaps explained by low genetic variation, slower life histories and reduced sexual selection in island populations. Extrapair paternit[...]
Article
Eduardo Garcia-Del-Rey, Auteur ; Charles T. Collins, Auteur ; Nicholas W. Volpone, AuteurAs a first step to investigate the foraging ecology of the Plain Swift Apus unicolor in the Canary Islands, we studied the food brought to the nestlings. A total of 12,800 aerial prey items were identified from 32 food boluses. 97.3% of the prey[...]
Article
Eduardo Garcia-Del-Rey, Auteur ; Mark J. Whittingham, AuteurFarmland birds within arable land are of conservation concern in Europe, but little is known about their ecology in the oceanic islands of the Mediterranean Basin (Macaronesia). We report here that, during two consecutive winters and within the [...]
Article
Eduardo Garcia-Del-Rey, Auteur ; Ruediger Otto, Auteur ; Jose Maria Fernandez-Palacios, AuteurWe studied the medium-term response of the endemic Blue Chaffinch Fringilla teydea teydea to experimental thinning in a Pinus canariensis plantation on the island of Tenerife during breeding season. Distance Sampling method was applied to line t[...]
Article
Christian Dietzen, Auteur ; Eduardo Garcia-Del-Rey, Auteur ; Guillermo Delgado Castro, Auteur ; Michael Wink, AuteurAn analysis of the sequences of the mitochondrial cytochrome b gene (1005 bp) of the Parus teneriffae-group from the Canary Islands and North Africa revealed new insights into the phylogeography of this taxon. The origin of the radiation on the [...]

Article
Eduardo Garcia-Del-Rey, Auteur ; Gunnhild Marthinsen, Auteur ; Pascual Calabuig, Auteur ; Loly Estevez, Auteur ; Lars Erik Johannessen, Auteur ; Arild Johnsen, Auteur ; Terje Laskemoen, Auteur ; Jan T. Lifjeld, AuteurThe Blue Chaffinch (Fringilla teydea) is endemic to the Canary Islands and restricted to the pine forests on Tenerife (ssp. teydea) and Gran Canaria (ssp. polatzeki). While the teydea population is large and stable, the polatzeki population unde[...]
Article
The status of the 'Endangered' Fuerteventura Stonechat Saxicola dacotiae, a western Palearctic single island endemic, was assessed 22 years after the first population estimate of 1,300-1,700 individuals was made by Bibby and Hill (1987). Using G[...]
Article
Javier Gonzalez, Auteur ; Guillermo Delgado Castro, Auteur ; Eduardo Garcia-Del-Rey, Auteur ; Carola Berger, Auteur ; Michael Wink, AuteurDNA nucleotide sequences from two mitochondrial genes (cytochrome b and NADH dehydrogenase subunit 2) and the nuclear intron 7 of beta-fibrinogen were obtained to infer the phylogenetic origin of the two endemic Canarian pigeons: Bolle's Pigeon [...]
