Diurnal birds of prey (Falconiformes)

2009
Abstract the diurnal birds of prey constitute the Order Falconiformes, and are generally classiAed into Ave reciprocally monophyletic families (1): Cathartidae (New World vultures, seven species; North and South America), Sagittariidae (Secretary Bird, one species; Africa), Pandionidae (Osprey, one species; cosmopolitan), Accipitridae ...

Ordnung: Falconiformes – Falken

2020
Innerhalb der Ordnung der Falconiformes mit der einzigen Familie Falconidae sind die Falken mit 66 Arten in 11 Gattungen fast weltweit verbreitet. Die Familie wird gegenwartig in zwei Unterfamilien unterteilt, namlich die Herpetotherinae (Waldfalken) mit zwei Gattungen (Herpetotheres und Micrastur) und die Falconinae mit insgesamt neun Gattungen, unter

Telephoto lens system of falconiform eyes

Nature, 1978
VISUAL ACUITY in falconiform birds has been shown to be higher than man. For instance, vultures with eyes similar in size to those of man have a grating detectability of about twice the spatial frequency of man1. This is consistent with measured image quality in an eagle eye similar in size to the human eye2.

Leucocytozoon (Haemosporida; Leucocytozoidae) of the Falconiformes

Canadian Journal of Zoology, 1977
Falconiform-inhabiting species of Leucocytozoon are reviewed and a checklist of Falconiformes known to harbor Leucocytozoon is included. Morphological measurements were made from 11 falconiform species to examine the interspecific and intraspecific variations. These formed the basis for the redescription of gametocytes of L. toddi Sambon.

Karyological heterogeneity in the Falconiformes (aves)

Experientia, 1975
Chromosome studies in 4 families of Falconiformes, Cathartidae, Falconidae, Sagittariidae and Accipitridae showed that the karyological variety in this order is much wider than in any other avian order, which underlines the heterogeneous character of the group.

The chromosomes of four species of Falconiformes

Experientia, 1976
Leucocyte cultures were used in four species of Falconiformes for the purpose of karyotypic sex determination and the establishment of a breeding pair. The Andean condor has 80 Guiana eagle 54, Crane hawk 66, and Turkey vulture 76 chromosomes with readily distinguished ZW elements in the female.

The karyograms of some Falconiformes and Strigiformes

Chromosoma, 1966
The chromosome complements of cultured cells of the Falconidae are characterized by their low values: 2n=52 in Falco tinnunculus. 2n=68 in Buteo buteo, 64 in an unknown species (Accipiter nisus ?). The Strigidae have high chromosome numbers: 82 in Strix aluco and Athene noctua, 92 in Tyto alba.

HAEMATOLOGIC PARAMETERS ON VARIOUS SPECIES OF STRIGIFORMES AND FALCONIFORMES

Journal of Wildlife Diseases, 1978
Normal mean values for packed cell volume, total erythrocyte count, total leukocyte count, total protein and mean corpuscular volume were obtained from 37 species of Strigiformes and Falconiformes representing 207 individuals.

A survey of free-living falconiform birds for Salmonella

Journal of the American Veterinary Medical Association, 1986
SUMMARY Of 105 migrating falconiform birds of 7 species examined for Salmonella shedding in New Jersey, 2 (1.9%) were positive for Salmonella spp. Both positive birds were immature red-tailed hawks (Buteo jamaicensis). Salmonella enteritidis and S newport were the serotypes isolated.

Trichomoniasis in birds of prey (order Falconiformes) in Bahrain

Veterinary Record, 1995
Of 5360 falcons examined at the Sulman Falcon Hospital in Bahrain between 1987 and 1993, 1675 (31.2 per cent) had lesions of trichomoniasis. These lesions were commonly found in the oral and nasal cavities, the infraorbital sinuses, the crop and oesophagus and, more rarely, in the coelomic cavity, attached to the wall of the abdominal air sacs, and in ...
