Barn Owl <italic>Tyto alba</italic> pellets and loose bones on a cave floor from Amorgos (Cyclades, Greece) were examined and the birds found to have caught at least 39 species of bird, mostly identified from humeri, plus shrews <italic>Crocidura suaveolens</italic>, a few lizards and dung beetles, in addition to their principal diet of rodents (rats <italic>Rattus rattus</italic>, mice <italic>Apodemus</italic> spp. &amp; <italic>Mus musculus</italic>). Amongst the birds, migrants appeared most vulnerable to owl predation, with some notable exceptions, while resident species were under-represented. The range of bird species found appears to be the largest recorded for any Barn Owl study of a single site. Considerable differences were found in species proportions of taxa in fresh pellets and in loose bones, probably due to differential rates of degradation. Photographs of all humeri are included to aid identification in other studies.

The diet, and pellet residue taphonomy, of Barn Owls <italic>Tyto alba</italic> on a Greek island reveals an exceptional diversity of avian prey

The Goosander <italic>Mergus merganser</italic> was not recorded breeding in Bulgaria till recently. We present herewith the very first record of the species breeding in the country and estimate the size of its breeding population in Bulgaria. Thus, we propose a change in its status in the country with more effort to be invested in the survey of this small, isolated population.

Grassland birds were surveyed in two mountain pastures (Zaprikraj and Zapleč) in the southern part of the Julian Alps, Slovenia. The survey was carried out during the mornings between 26 and 30 June 2005. Due to the incomplete survey (only one visit, no nocturnal or targeted surveys and late season survey), the surveyed birds’ breeding density is only a rough estimate. 167 pairs belonging to 12 species were counted, with Tree (average density of 1.64 p/10 ha) and Water Pipit (average density of 1.60 p / 10 ha) being the most abundant. Both were observed in all altitudinal belts. The highest density in individual altitudinal belt was calculated for Red-backed Shrike <italic>Lanius collurio</italic> (3.78 p/10 ha) and Water Pipit (3.61 p/10 ha). In well preserved grasslands in the study area, most species reached high breeding densities compared to other parts of Slovenia and all were recorded higher than during the 1992 survey, although still mostly within limits of the elevations elsewhere in Slovenia. Breeding density of Skylark <italic>Alauda arvensis</italic> decreased with the elevation. Whinchat <italic>Saxicola rubetra</italic>, Skylark and Red-backed Shrike used significantly gentler slopes, while Pipits showed no preference for particular slopes.
