Natal Dispersal and Recruitment of Two Bonelli's Eagles Aquila fasciata: a Four-Year Satellite Tracking Study
To study natal dispersal and recruitment to the breeding population in Bonelli’s Eagle, two nestlings were tagged with satellite transmitters in the Iberian Peninsula in 2002. Their monthly ranges and distances were computed and fitted to regression models to describe their general trend. One bird, a female, dispersed and settled rapidly in an area which she explored intensively during four yea...
متن کاملThe coexistence of the eagles Aquila chrysaetos and Hieraaetus fasciatus increases with low human population density, intermediate temperature, and high prey diversity
Competition among species with similar ecological requirements may preclude species coexistence. However, species with similar requirements may coexist under determinate environmental conditions. Major effort is being dedicated to conserve the golden eagle (Aquila chrysaetos) and Bonelli’s eagle (Hieraaetus fasciatus) in Spain, two raptors with similar ecological requirements. This work analyse...
متن کاملInfluence of climate on Bonelli’s eagle’s (Hieraaetus fasciatus V. 1822) breeding success through the Western Mediterranean
Aim To assess the impact of certain climatic variables on the breeding success of some populations of Bonelli’s eagle (Hieraaetus fasciatus V. 1822) throughout its latitudinal distribution range, in order to account for recent and differential declines in populations. Location Western Mediterranean, from southern Morocco to southern France. Methods Seven populations were considered for the lati...
متن کاملIn ̄uence of prey densities in the distribution and breeding success of Bonelli's eagle (Hieraaetus fasciatus): management implications
Diet, prey availability, and breeding success were studied in a population of Bonelli's eagle (Hieraaetus fasciatus) in the province of Granada, SE Spain. The densities of the main prey species, European wild rabbit (Oryctolagus cuniculus), red-legged partridge (Alectoris rufa), wood pigeon (Columba palumbus), and rock dove (Columba livia), representing 90.2% of the biomass, were analysed in 19...
متن کاملA multi-gene phylogeny of aquiline eagles (Aves: Accipitriformes) reveals extensive paraphyly at the genus level.
The phylogeny of the tribe Aquilini (eagles with fully feathered tarsi) was investigated using 4.2 kb of DNA sequence of one mitochondrial (cyt b) and three nuclear loci (RAG-1 coding region, LDH intron 3, and adenylate-kinase intron 5). Phylogenetic signal was highly congruent and complementary between mtDNA and nuclear genes. In addition to single-nucleotide variation, shared deletions in nuc...
