Raptors from the orders Accipitriformes and Falconiformes have been considered to rely principally on vision. Historically, this assumption has led scientists to discount any possible sense of smell in these birds, until work on cathartid vultures ...

Occurrence of Chlamydiaceae in Raptors and Crows in Switzerland
Bacteria of the family Chlamydiaceae are globally disseminated and able to infect many bird species. So far, 11 species of Chlamydia have been detected in wild birds, and several studies found chlamydial strains classified as genetically intermediate ...

The breeding performance of raptors in urban landscapes: a review and meta-analysis [PDF]
Global urbanisation is rapidly increasing and can have profound impacts on wild flora and fauna. For many species, the impacts are detrimental and irreversible, whereas others are able to colonise and apparently thrive in these novel, human-made ...

Avian haemosporidian parasites of accipitriform raptors
Background The order Accipitriformes comprises the largest group of birds of prey with 260 species in four families. So far, 21 haemosporidian parasite species have been described from or reported to occur in accipitriform birds.

Conservation Letter: Raptors and Anticoagulant Rodenticides
Widespread use of anticoagulant rodenticides (ARs) creates an ongoing global conservation concern for raptors. ARs have the potential to negatively affect birds primarily by secondary exposure (via scavenging or depredating primary consumers of ARs ...

DEVELOPMENTAL OCULAR DISEASE OF RAPTORS [PDF]
Sixteen raptors, including one eagle, two falcons, five hawks and eight owls, were found to have developmental ocular lesions. The most common lesion was microphthalmia. Other findings included cataract, microphakia, retinal dysplasia, malformation of the ciliary body, choroid and pecten, and lentoid formation.

Raptor hunted by caspases [PDF]
Emergence of survival strategies is a key step for organisms during evolution. The capacity to adapt from nutrient-rich to nutrient-poor environments led to the appearance of protein complexes regulating anabolic and catabolic pathways. The evolutionarily conserved kinase mTOR (mechanistic target of rapamycin) emerged as a crucial and central protein ...

In this paper, an extension of raptor codes is introduced which keeps all the desirable properties of raptor codes, including the linear complexity of encoding and decoding per information bit, unchanged. The new design, however, improves the performance in terms of the reception rate.

The fecal microbiota of wild and captive raptors
Background The microorganisms populating the gastro-intestinal tract of vertebrates, collectively known as “microbiota”, play an essential role in digestion and are important in regulating the immune response.
