Description
Summary:We surveyed the birds of prey and owls carried out on the territories of forest-steppe regions of the Ust-Ordynsk autonomous district in 2006. Surveys were carried out during vehicle routes and covered all of 6 regions of the district. The total length of vehicle routes was 13155 km in 2006. The results of surveys of birds on prey are in the table 1, owls in the table 2. We registered 19 species of birds of prey and 6 species of owls in 2006. We revealed following species as common: Black-eared Kite (Milvus migrans lineatus), Hen Harrier (Circus cyaneus), Common Buzzard (Buteo buteo), Upland Buzzard (Buteo hemilasius), Kestrel (Falco tinnunculus), and Rough-legged Buzzard (Buteo lagopus) as common wintering species. Following species were noted as rare: Golden Eagle (Aquila chrysaetos), Imperial Eagle (Aquila heliaca), Great Spotted Eagle (Aquila clanga), Steppe Eagle (Aquila nipalensis), Booted Eagle (Hieraaetus pennatus), Peregrine Falcon (Falco peregrinus), Saker Falcon (Falco cherrug), Eagle Owl (Bubo bubo). We found nests of Upland Buzzard, Golden Eagle, Peregrine Falcon, Kestrel, Eagle Owl, Long-eared Owl (Asio otus) and Ural Owl (Strix uralensis). There were the new record of the Merlin (Falco columbarius) in summer and new records of Western and Eastern Marsh Harriers (Circus aeruginosus aeruginosus, C. a. spilonotus). Besides the Rough-legged Buzzard we noted as wintering Upland Buzzard, Goshawk (Accipiter gentilis), Golden Eagle, Merlin and may be Kestrel. We noted the number of rodents has decreased in 2006 and certainly impacted on the number of raptors. Despite of this fact the number of raptors on the territory of the Ust-Ordynsk autonomous district is higher than on nearest territories of the Irkutsk district. Partly it can be explained as the result of traditional careful respect of local people to the birds of prey.
