Concentrations of 16 polycyclic aromatic hydrocarbons (PAHs), 19 polybrominated diphenyl ethers (PBDEs), 7 polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), isomers and metabolites of dichlorodiphenyltrichloroethane (DDTs) and Hexachlorocyclohexane (HCHs) were measured in the feathers of the Red-billed Chough Pyrrhocorax pyrrhocorax, a rare and protected corvid species inhabiting rural...

Objective- The objective of the present study was to define electrocardiographic data following intranasal administration of diazepam, midazolam and xylazine with or without Ketamine in Chough. Design- To determine the heart effects of anesthetics in intranasal administration, an experimental in vivo study was employed. Animals- Ten healthy Choughs were examined in the current study...

The prevalence of hematozoa in two populations of red-billed choughs (Pyrrhocorax pyrrhocorax) was sampled in 1992 and 1994 in Spain. Two blood parasites infected red-billed choughs. A species of Plasmodium, possibly Plasmodium relictum, and the piroplasm Babesia frugilegica, are described for the first time from this host. Low prevalence (1/178, < 1%) of hematozoa in these populations, was evi...

BACKGROUND Corvidae is a cosmopolitan family of oscine birds including crows, rooks, magpies, jays, chough, and ravens. These birds are migratory species, especially in the shortage of foods, so they can act like vectors for a wide range of microorganisms. They live generally in temperate climates and in a very close contact with human residential areas as well as poultry farms. There is no ava...

Social barriers have been shown to reduce gene flow and contribute to genetic structure among populations in species with high cognitive capacity and complex societies, such as cetaceans, apes and humans. In birds, high dispersal capacity is thought to prevent population divergence unless major geographical or habitat barriers induce isolation patterns by dispersal, colonization or adaptation l...

Acuaria anthuris (Rudolphi, 1819). Worms, which I ha ve referred to this species, were found in the gizzard of a Red-billed Chough (Graculus eremita). One female worm of this species has been previously recorded by Baylis and Daubney (1922) from an Indian host, viz., the Red-billed Blue Magpie (Urocissa occipitalis). According to Cram (1927) the only hosts from wltich this worm has been recorde...
