Results from the months February-September showed that in all areas, the most important prey for the Barn Owl were small mammals (mainly Mus spp., Microtus rossiaemeridionalis, Crocidura spp. and Apodemus spp.) The mammalian prey composition showed winter-summer and among-areas differences. Except in the Evros Delta, where small mammals were dominant by both numbers and biomass, the most numerous prey of the Little Owl were insects (mainly Orthoptera and Coleoptera), but small mammals (mainly M. rossiaemeridionalis and Mus spp.) dominated the diet by biomass. Significant seasonal differences in prey composition occured in the Evros Delta, while the summer diets were also different among wetlands. Barn Owl median prey biomass (MPB) was significantly higher than Little Owl MPB in summer, whereas prey diversity and evenness values were higher in the latter species as a consequence of considerable amounts of insects in its diet. In both owl species, MPB differed significantly among the wetlands in the year of study, while seasonal differences occurred occasionally in some of the wetlands. The total prey overlap (Pianka{\textquoteright}s symmetric equation) of the two owl species in the summer (range 27\%-53\%) was lower than the mammalian prey overlap (60\%-97\%) and both were greater than those found by other authors in most parts of the Mediterranean.}, keywords = {Aves, Barn Owl Tyto alba, diet, Greece, Little Owl Athene noctua, wetland}, author = {Goutner, V. and Alivizatos, H.} } @article {14314, title = {The diet of Eurasian griffons (Gyps fulvus) in Crete}, journal = {Journal of Raptor ResearchJournal of Raptor Research}, volume = {39}, number = {2}, year = {2005}, note = {Times Cited: 0ArticleEnglishCited References Count: 29964da}, month = {JUN}, pages = {179-183}, keywords = {Aves, Crete, diet, eurasian griffon, gypaetus-barbatus, gyps fulvus, pellet analysis, vultures gyps}, author = {Xirouchakis, S.

In total, 267 regurgitations from little egrets, 247 from night herons and 19 from squacco herons (only in 1995) were collected and analyzed. Each prey item was identified to the lowest possible taxon. The dry mass of each prey taxon was also estimated from oven-dried prey specimens collected in the field. At least 58 different prey taxa were identified among 5,108 items found in little egret regurgitations, at least 45 taxa among 2,373 items regurgitated by night herons and 12 taxa among 277 items from squacco herons regurgitations. Differences were detected between the three ardeid species in the proportion of each prey category. Little egret nestlings were mainly fed fish (39.6\% by number) and insects (32.0\%), but amphibians and fish were the most important groups by biomass (44.9\% and 32.9\% respectively). The proportions of prey categories varied significantly between years ({\textdiv}212 = 922.91, p < 0.001). The night heron nestlings were mainly fed insects and the crustacean Triops cancriformis, although the dry mass of the latter contributed little to the consumed biomass (4.0\% compared to the 37.9\% of insects). Small mammals and reptiles were included in the diet of the young night herons, while the fish they ate were much bigger than those consumed by little egret nestlings. The proportions of the night herons{\textquoteright} main prey categories varied significantly between years ({\textdiv} 224 = 598.67, p < 0.001). Squacco heron chicks were fed mainly insects (50.9\%) and amphibians (31.8\%), the latter being more important by biomass (73.6\%). In a cluster analysis, diet of young little egrets and night herons showed greater similarity from 1988 to 1990 than between 1994 and 1995, suggesting temporal changes in prey use. Study years tended to group separately for each species, but those of the little egret were more scattered in the cluster than the night heron{\textquoteright}s, thus reflecting greater prey use variability. The diet of the squacco heron was similar to that of the little egret when prey type frequencies were considered, but closer to the night heron{\textquoteright}s by dry mass. The dry mass differed significantly between the species ({\textdiv}2 = 87.39, p < 0.001, Kruskal-Wallis test).

Rice fields offered better conditions to foraging herons than natural habitats in northwestern and northeastern Italy where the number of feeding herons, food intake rates, and prey abundance in rice fields were higher. The proportion of the food resources obtained by herons from the agricultural habitats, rice fields and small irrigation canals was estimated using two independent methods. Six heron species acquired more than half of their food from rice fields in all the regions except the Rhone Delta where agricultural habitats offered less prey. We conclude that rice fields are the main foraging habitat for herons breeding in Mediterranean Europe, and we urge authorities to consider the special importance of rice field management to the conservation of Mediterranean herons.}, keywords = {Aves, conservation, diet, Feeding success, Foraging habitat, Herons, Prey availability, Rice fields}, author = {Fasola, M. and Canova, L. and Saino, N.} } @article {2767, title = {The summer diet of the little owl (Athene noctua) on the Island of Astipalaia (Dodecanese, Greece)}, journal = {Journal of Raptor ResearchJournal of Raptor Research}, volume = {31}, number = {3}, year = {1997}, note = {TY - JOURCited By (since 1996): 3Export Date: 7 September 2006Source: ScopusReferences: Angelici, F.M., Capula, M., Riga, F., Notes on the herpetofauna of Astipalaia island (Dodecanese, Greece) (1990) Brit.

This study reports on the seasonal, sex, and age differences in the diet composition of a population of the lacertid lizard Podarcis milensis inhabiting an arid sand dune on Milos Island (Aegean Archipelago, Greece). Stomach contents of 191 animals were analyzed and compared with prey availability data. The most important prey types were Hemiptera, Coleoptera (other than Tenebrionidae), spiders, and ants. Other prey items included plant material and insect larvae, both constantly consumed throughout the year. Differences in the taxonomic composition of the diet were found between males and females and between juveniles and all other classes. The greatest similarity of diet composition between the sexes and ages examined was during summer. The foraging patterns observed are discussed within the context of the specific study system: an insular, low productivity, sand dune ecosystem.

In the present study data on the diet composition of three non sympatric lacertid lizard species of the Aegean archipelago (Greece) are given. The stomach contents of 157 specimens of Podarcis milensis (62), Podarcis gaigeae (50) and Podarcis erhardii (45) were examined for prey remnants. All animals come from Museum collections and were sampled during summer.
