Nesting Habitat Selection of Booted Eagle Hieraaetus Pennatus in Central Catalonia

—Nesting habitat selection of Booted Eagle Hieraaetus pennatus in central Catalonia. Aims: The Booted Eagle Hieraaetus pennatus is a poorly known raptor that has bred in Catalonia at least since 1989, when the first nest was found. Its confirmed breeding population has increased from 1 breeding pair in 1989 to 13 breeding pairs in 2001. The present study provides information about the populatio...

Phylogeny of eagles, Old World vultures, and other Accipitridae based on nuclear and mitochondrial DNA.

We assessed phylogenetic relationships for birds of prey in the family Accipitridae using molecular sequence from two mitochondrial genes (1047 bases ND2 and 1041 bases cyt-b) and one nuclear intron (1074 bases beta-fibrinogen intron 7). We sampled representatives of all 14 Accipitridae subfamilies, focusing on four subfamilies of eagles (booted eagles, sea eagles, harpy eagles, and snake eagle...

A 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...

Lead and arsenic in bones of birds of prey from Spain.

The bones (humerus and/or femur) of 229 birds of prey from 11 species were analyzed for Pb and As to evaluate their exposure to Pb shot. The species with the highest mean Pb levels were red kite (Milvus milvus) and Eurasian griffon (Gyps fulvus), and the species with the lowest levels were Eurasian buzzard (Buteo buteo) and booted eagle (Hieraaetus pennatus). Red kite also had the highest mean ...
