Date to the knowledge of small mammal fauna of Somogy county (Hungary), based on Barn Owl Tyto alba (Scopoli, 1769) pellet analysis

JENŐ J. PURGER

Barn Owl pellets collected in Somogy county were analysed, with the purpose of contributing to the knowledge about small mammal fauna of the county with new data. Pellets were collected between 1995 and 2016, from 53 localities (investigated areas: XL89, XL99, YL08, YL09, XM52, XM61, XM62, XM70, XM72, XM74, XM80, XM81, XM82, XM83, XM84, XM90, XM91, XM93, XM95, YM02, YM03, YM12, YM13, YM14, YM22, YM23, YM24 and BS73, according to 10x10 km UTM grids). In a total of 5164 Barn Owl pellets 14360 prey remnants were found (2.8 was the prey per pellet ratio). In the diet of Barn Owls small mammals dominated (98.6%), while the remnants of birds, amphibians and insects made up 1.4% of total prey. Distribution data for 27 small mammal species (from this 15 protected species *) are presented. Mammal

prey consisted of Soricomorpha 42.3% (Crocidura leucodon*, C. suaveolens*, Sorex araneus*, S. minutus*, Neomys anomalus*, N. fodiens*, Talpa europaea*), Chiroptera 0.03% (Eptesicus serotinus*, Nyctalus leisleri*, N. noctula*, Myotis myotis*) and Rodentia 57.6% (Muscardinus avellanarius*, Microtus agrestis*, M. arvalis, M. subterraneus, Arvicola amphibius, Myodes glareolus, Apodemus agrarius, A. flavicollis, A. sylvaticus, A. uralensis, Micromys minutus*, Mus musculus, M. spicilegus, Rattus norvegicus, R. rattus), but the remnants of one Weasel Mustela nivalis* (Carnivora) were also found in the owl pellets. The majority of these data confirm our earlier knowledge about the distribution of particular species, but in the case of 9 small mammal species, new occurrence data are provided.
