Canary (Serinus canaria) Science Article 1 abstract The radiation of canaries (genus Serinus) occurred in Africa and Eurasia during the Miocene Epoch (9 million years ago) according to maximum parsimony (MP), neighbor-joining (NJ), maximum likelihood (ML) and Bayesian methodologies. Serinus canaria (wild canary) and S. serinus (European serin) together form one of the several polytomies […]

FIRST RECORD OF THE CAPE GANNET MORUS CAPENSIS FOR PERUAND THE PACIFIC OCEAN
Cape Gannet (Morus capensis) Science Article 1 abstract The Cape Gannet Morus capensis is an endemic seabird to southern Africa, breeding on offshore islands off Namibia and South Africa (Harrison 1985). After breeding, dispersal takes place as far as Mozambique, rarely Tanzania, on the east coast of Africa, and to the Gulf of Guinea on […]
Site fidelity in the Canary Islands stonechat Saxicoladacotiae in relation to spatial and temporalpatterns of habitat suitability
Canary Islands Stonechat (Saxicola dacotiae) Science Article 2 abstract We investigate the degree of territory faithfulness of the Canary Islands stonechat Saxicola dacotiae, an endemic bird species of the semi-arid island of Fuerteventura (Canary Islands, Spain), and the spatial and temporal variability of habitat traits related to its breeding success over its whole distribution range. […]
Biometrics, ageing, sexing and moult of the Blue Chaffinch Fringilla teydea teydea on Tenerife (Canary Islands)
Blue Chaffinch (Fringilla teydea) Science Article 1 abstract The Blue Chaffinch Fringilla teydea is one of a few Palearctic species for which biometric data are lacking from the field; we address this issue here. Blue Chaffinches were caught by mist net, at ten sites on Tenerife (Canary Islands), and measured. Data on biometrics and moult […]
Density estimates, microhabitat selection and foraging behaviour of the endemic Blue Chaffinch Fringilla teydea teydea on Tenerife (Canary Islands)
Blue Chaffinch (Fringilla teydea) Science Article 2 abstract Point counts were used for censusing birds. Data were analysed with the DISTANCE software programs using an average detectability function. Microhabitat structure was characterized by measuring 11 variables in a 25m radius at each point. We used Poisson regression models to predict counts for Blue Chaffinch from […]
Berthelot’s Pipit feeding on lizard
Berthelots Pipit (Anthus berthelotii) Science Article 1 abstract On 29th August 2006, we observed several Berthelot’s Pipits Anthus berthelotii feeding along the rocky coast of La Santa, Lanzarote, Canary Islands.

ENERGY AND WATER BUDGETS OF LARKS IN A LIFE HISTORYPERSPECTIVE: PARENTAL EFFORT VARIES WITH ARIDITY
Bar-tailed Lark (Ammomanes cinctura) Science Article 1 abstract We compared physiological, demographic, and ecological variables of larksto gain insights into life history variation along an aridity gradient, incorporating phylogeneticrelationships in analyses when appropriate. Quantifying field metabolic rate (FMR)and water influx rate (WIR) of parents feeding nestlings as measures of parental effort, wefound that parental FMR […]

Sacred Ibis: a new invasive species in Europe
African Sacred Ibis (Threskiornis aethiopicus) Science Article 1 abstract Sacred Ibis Threskiornis aethiopicus is closelyrelated to both Black-headed Ibis T. melanocephalus(from the Indian subcontinent) andAustralian White Ibis T. molucca (which breedsin Australia, New Guinea and some nearbyislands)-to the point that they are sometimestreated as one species, T. aethiopicus. However,they are generally regarded as three distinctspecies […]
