Ordnung: Accipitriformes – Greifvögel
2020Die Ordnung Accipitriformes setzt sich nach der systematischen Auffassung bei del Hoyo und Collar (2014) aus 3 Familien, 71 Gattungen und 250 Arten zusammen. Die Familien Sagittariidae (Sekretare) und Pandionidae (Fischadler) bestehen aus nur jeweils einer Spezies.

Helminth infestation in birds of prey (Accipitriformes and Falconiformes) in Southern Italy
The Veterinary Journal, 2010Helminth 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.

Eye Size, Fovea, and Foraging Ecology in Accipitriform Raptors
Brain, Behavior and Evolution, 2017Birds 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, 2012We 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.

Accipitriformes at the Laverton Saltworks, Victoria, 1950–53
Emu - Austral Ornithology, 1963This report, the fourth in a series, deals with the Accipitriformes recorded in the Laverton saltworks during a survey of the area between June 1950 and June 1953. Observations, by members of the Altona Survey Group, are given on the status, numbers, seasonal fluctuations, field characteristics, food, and breeding of the 12 species recorded during the ...

A comparative study on grasping‐related muscles in five Accipitriformes species
The Anatomical RecordAbstractAccipitriformes are diverse in their prey preferences and use their grasping feet for hunting. Little is known about the architectural design of muscles related to grasping among species of different sizes, diets, and foraging behaviors. In the present study, we report quantitative data and analysis of the pelvic musculature of the Japanese ...

Taxonomic status of Harlan’s Hawk Buteo jamaicensis harlani (Aves: Accipitriformes)
Zootaxa, 2018Since 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).

An ideal taxonomy for organisms incorporates comprehensive knowledge of existing species diversity and their phylogenetic relationships. This knowledge is used in developing consistent criteria for recognizing and naming species as well as monophyletic groups (clades) above the species level, including genera, families, and orders.
