Eye Size, Fovea, and Foraging Ecology in Accipitriform Raptors

Brain, Behavior and Evolution, 2017
Birds with larger eyes are predicted to have higher spatial resolution because of their larger retinal image. Raptors are well known for their acute vision, mediated by their deep central fovea. Because foraging strategies may demand specific visual adaptations, eye size and fovea may differ between species with different foraging ecology.

Helminth Community Structure in Birds of Prey (Accipitriformes and Falconiformes) in Southern Italy

Journal of Parasitology, 2012
We compared helminth communities in 6 species of birds of prey from the Calabria region of southern Italy. In total, 31 helminth taxa, including 17 nematodes, 9 digeneans, 3 acanthocephalans, and 2 cestodes, were found. All helminth species were observed in the gastrointestinal tract, except for 3 spirurid nematodes.

Helminth infestation in birds of prey (Accipitriformes and Falconiformes) in Southern Italy

The Veterinary Journal, 2010
Helminth infestation was identified at post mortem examination in 110/116 (95%) raptors belonging to six species in Southern Italy. Pathological changes associated with helminths were observed in 81/110 (74%) of birds. Lesions in the respiratory system were associated with the nematode Serratospiculum tendo only in Falco peregrinus.

Bulletin of the Natural History Museum – Plovdiv
The importance of political, economic and cultural factors/developments in explaining fundamental ornithological problems, one of which is the existence of vultures, is analyzed, with a special emphasis on Bulgaria.

SPATIAL DISTRIBUTION OF GREATER SPOTTED EAGLES (CLANGA CLANGA, ACCIPITRIDAE, ACCIPITRIFORMES) DURING THE WINTERING PERIOD AND FEATURES OF THEIR HABITATS DETERMINED USING GPS-GSM TELEMETRY

Zoologiceskij zurnal, 2023
Using GPS-GSM trackers, data on the spatial distribution and habitat features during the wintering period were obtained for five young greater spotted eagles (Clanga clanga) tagged in the center of European Russia or the Middle Volga region.

Hindlimb myology in two piscivorous raptorial birds: a quantitative comparison of the osprey and the white‐tailed sea eagle (Aves, Accipitriformes)

Journal of Zoology
The hindlimbs of Accipitriformes are vital for capturing prey. Research on hindlimb musculature has primarily focused on species preferring avian and mammalian prey, whereas piscivorous species have received limited attention.

Genetic relationships of populations of the Black Kite Milvus migrans (Accipitriformes: Accipitridae) in the east of its range in Asia and Australia.

Zootaxa
While the Black Kite Milvus migrans is one of the most widespread birds of prey, occurring over Eurasia, Africa and Australia, it remains poorly understood outside of Europe, with southeast Asian populations particularly mysterious as their taxonomy is ...

Taxonomic status of Harlan’s Hawk Buteo jamaicensis harlani (Aves: Accipitriformes)

Zootaxa, 2018
Since its description in 1830 by Audubon, Harlan’s Hawk (taxon harlani) has been considered both as a species (Buteo harlani) (1830–1891 and 1944–1972) and as a subspecies of Red-tailed Hawk (B. jamaicensis harlani) (1891–1944 and 1973 to present).
