The Complete Sequence of the Mitochondrial Genome of Buteo buteo (Aves, Accipitrid ) Indicates an Early Split in the Phylogeny of Raptors

Common Buzzard (Buteo buteo) Science Article 3 abstract The complete sequence of the mitochondrial (mt) genome of Buteo buteo was determined. Its gene content and nucleotide composition are typical for avian genomes. Due to expanded noncoding sequences, Buteo possesses the longest mt genome sequenced so far (18,674 bp). The gene order comprising the control region […]

Numerical response of common buzzards and predation rate of main and alternative prey under fluctuating food conditions.

Common Buzzard (Buteo buteo) Science Article 2 abstract We studied the numerical response of a population of the common buzzard Buteo buteo to the fluctuations of its main prey (voles) and alternative prey (forest grouse) in western Finland between 1979 and 1996. Populations of main prey fluctuated in a cyclic manner with three years between […]

Sexing, ageing and moult of Buzzards Buteo buteo in a southern European area

Common Buzzard (Buteo buteo) Science Article 1 abstract In order to obtain a reliable method for sexing and ageing Buzzards Buteo buteo breeding in southern Europe, 115 birds from a wildlife rehabilitation centre and 43 trapped birds were measured, sexed and aged over four years (2000-2003). Dead birds were sexed by examining their gonads, and […]

Diet of Common Buzzards (Buteo buteo) in southern Norway determined from prey remains and video recordings.

Common Buzzard (Buteo buteo) Science Article 5 abstract We examined the diet of six breeding Common Buzzard (Buteo buteo) pairs in southern Norway, by analysing pellets and prey remains collected around and in nests, and by video recording prey delivery at the nests. Mammals, birds and reptiles were the major prey groups. Amphibians were underestimated […]

Breeding density and brood size of Common Buzzard Buteo buteo in relation to snow cover in spring

Common Buzzard (Buteo buteo) Science Article 4 abstract In a 500 km2 study area situated 100-400 m above sea level in southern Norway, breeding density and offspring production of Common Buzzard Buteo buteo was studied in relation to snow depth in spring during 1985-97. Because a thick snow layer will reduce the availability of the […]
