Feeding ecology of a population of goshawk Accipiter gentilis
. J Ornithol.
This is consistent with the IOP of adult and juvenile northern goshawks (Accipiter gentilis
), common buzzards, and common kestrels (Falco tinnunculus).
One year later, in August 2004, a goshawk (Accipiter gentilis
) fledgling showed central nervous system symptoms and died in a national park in southeastern Hungary.

In a study performed in free-living goshawks (Accipiter gentilis
), culture of the feet of these birds identified numerous species, including Staphylococcus aureus and Staphylococcus epidermis, but also many enteric-associated bacteria such as Escherichia coli and Enterobacter species.
(3,4) Vertical transmission of Mycoplasma species in raptors was evaluated by culture and PCR testing of eggs and unhatched chick embryos, and only one egg from an imprinted, nonbreeding northern goshawk (Accipiter gentilis
) was positive on culture and PCR testing (n = 424, 0.2% prevalence).
(21-24) These reports include the repair of a large open wound on the distal antebrachium of a great horned owl (Bubo virginianus) (22); degloving injuries on the heads of northern goshawks (Accipiter gentilis
) (23); and wounds on the head of a red-tailed hawk, rock dove (Columba livia), and ring-necked pheasant (Phasianus colchicus).
Results showed IOP values varied by family and species, with the following mean IOP values (mm Hg [+ or -] SD) determined: white-tailed sea eagle (Haliaeetus albicilla), 26.9 [+ or -] 5.8; red kite (Milvus milvus), 13.0 [+ or -] 5.5; northern goshawk (Accipiter gentilis
), 18.3 [+ or -] 3.8; Eurasian sparrowhawk (Accipiter nisus), 15.5 [+ or -] 2.5; common buzzard (Buteo buteo), 26.9 [+ or -] 7.0; common kestrel (Falco tinnunculus), 9.8 [+ or -] 2.5; peregrine falcon, (Falco peregrinus), 12.7 [+ or -] 5.8; tawny owl (Strix aluco), 9.4 [+ or -] 4.1; long-eared owl (Asio otus), 7.8 [+ or -] 3.2; and barn owl (Tyto alba), 10.8 [+ or -] 3.8.
Serum chemistry panels and complete mineral and heavy metal screens were performed on blood samples from eight adult northern goshawks (Accipiter gentilis
) breeding in Pennsylvania.
(29,30) Pinched-off feathers have been described in different raptor species, such as the northern goshawk (Accipiter gentilis
), (32-34) the lizard buzzard (Kaupifalco monogrammicus), (31) and the common buzzard (Buteo buteo).
The digital egg monitor was also used to measure the heart rate of peregrine falcon (Falco peregrinus) and Northern goshawk (Accipiter gentilis
