The Forest Buzzard Buteo oreophilus rizonatus, confined to the temperate coastal and escarpment forests of South Africa (Hockey et al. 2005), is often considered to be a subspecies of the Mountain Buzzard Buteo oreophilus of the forested highlands of East Africa, following Siegfried (1971) and Siegfried and Frost (1973). However, both taxa are largely resident, with breeding distributions separ...

We have investigated the influence of heteroxenous coccidia (Apicomplexa: Eimeriorina) on the predation risk of intermediate hosts. Voles infected with Frenkelia spp. were found more frequently in buzzards' (Buteo buteo) prey than among snap-trapped rodents. To eliminate the possibility of traps selecting for uninfected rodents, a laboratory experiment was performed. Mice experimentally infecte...

On March 15, 2010, a highly pathogenic avian influenza virus was isolated from the carcass of a common buzzard (Buteo buteo) in Bulgaria. Phylogenetic analyses of the virus showed a close genetic relationship with influenza virus A (H5N1) clade 2.3.2.1 viruses isolated from wild birds in the Tyva Republic and Mongolia during 2009-2010. Designated A/common buzzard/Bulgaria/38WB/2010, this strain...

--The purpose of this study was to test the efficacy of oral administration of tiletamine/ zolazepam in a bait fbr immobilizing Common Buzzards (Buteo buteo) (N = 20). Two different dosages and two different methods of administration were compared. A dosage of 80 mg/kg was sufficient in most birds to enable safe handling after 30-60 min, whereas the majority of animals receiving 40 rag/ kg stil...

Wintering raptor populations were monitored between 1983 and 1988 in a 35 km2 study area centered 8 km north-northeast of the city of Boulder, Colorado. Raptors congregated around active prairie dog (Cynomys sp.) colonies. Golden eagles (Aquila chrysaetos) , ferruginous hawks (Buteo regalis), and red-tailed hawks (Buteo jamaicensis ) were observed hunting and capturing prairie dogs. Bald eagles...
