[Study on the make up of the diet of owls from the Niski Beskid Mts.]
Abstract:
SUMMARY. The author analyses the make-up of owls diet on the basis of pellets collected in the area of the Niski Beskid Mts. The Niski Beskid Mts. include the region of the greatest lowering of the Carpathian arch, situated between the West Carpathians and the East Carpathians (20°43′-22°15′E and 49°15′-49°46′N), and nowhere exceeding an altitude of 1000 m above sea level. Pellets were sought for in the attics and towers of churches in the summers of 1960 and 1961. The material thus obtained was derived from 25 localities: 18 of Tyto alba (Scopoli, 1769), 5 of Strix aluco Linnaeus, 1759, and 2 of Athene noctua (Scopoli, 1769). To calculate the number of victims in the pellets different methods were used for particular genera and even species so as to utilize the maximum number of identifiable parts (in some cases skulls, in others only mandibles). The author summed the contents of single pellets to obtain the final number of specimens of one species for each locality.
