Analiza cantitativă şi calitativă a hranei la Strigă (Tyto Alba Guttata) în judeţul Satu Mare

Subiect: Qualitative and quantitative analyses of Tyto alba guttata diet in Satu Mare County. During the research period we analysed 114 samples, collected from 41 locality in Satu Mare County between 1998 and 2004 (6 years of research). The collecting sites were the same in every year of the reseach. From the processed – dissected 7253 pellets were identified 28927 prey items belonging to 63 species and representing 43 genus. Small mammals were the main prey in the barn owl`s diet, belonging to following families: microtidae, muridae and soricidae. These taxons represent the major part of barn owl`s diet both in the total number of captured prey items and the prey biomass. M. arvalis was an important prey item in the barn owl`s diet and it seems to be an important regulating factor in the proportional representations of prey items. The mosaic-like, heterogeneous habitats and the low level of dietary specialization may explain probably the high diversity of barn owl`s diet composition in Satu Mare County.
