- The diet, and pellet residue taphonomy, of Barn Owls on a Greek island
reveals an exceptional diversity of avian prey
Abstract: Barn Owl Tyto alba 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 Crocidura suaveolens, a few lizards and dung beetles, in addition to their principal diet of rodents (rats Rattus rattus, mice Apodemus spp. & Mus musculus). 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 Goosander range expansion on the Balkan Peninsula and a new breeding
population in Bulgaria
Abstract: The Goosander Mergus merganser 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 bird species in mountain pastures Zaprikraj and Zapleč in the
southern Julian Alps, Slovenia
Abstract: 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 Lanius collurio (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 Alauda arvensis decreased with the elevation. Whinchat Saxicola rubetra, Skylark and Red-backed Shrike used significantly gentler slopes, while Pipits showed no preference for particular slopes.

- Population dynamics and habitat use by Northern Lapwing in agricultural
landscape of Dravsko and Ptujsko polje (NE Slovenia)
Abstract: The Northern Lapwing numbers across Europe are declining owing to its insufficient breeding success. To determine the size, dynamics and habitat use of the lapwing population at Dravsko and Ptujsko polje, a survey was carried out between 2016 and 2018. In 2016, 2017 and 2018, we recorded 148, 130, and 117 pairs, respectively. The population declined during the study and the population trend is uncertain. Approximately 12 to 21% of the national lapwing population was recorded at Dravsko and Ptujsko polje, making them one of the most important breeding areas in Slovenia. The majority of lapwings were found in bare tilled fields and fields with young spring crops that enable unbroken all-round views. Crop data analysis showed a significant preference for maize fields which are mostly bare tillage at the start of the incubation period and therefore act as an ecological trap for lapwings due to the time coincidence of the nesting period and farming operations. For the protection of the lapwing in Slovenia, we recommend a time limit of farming operations or avoiding individual nests while working in the field. Both measures are recommended to be implemented in combination with the provision of suitable foraging habitat for chicks. For greater effectiveness, we propose priority implementation of conser vation measures on traditiona l breeding sites.

- Rare birds in Slovenia in 2017 –Slovenian Rarities Committee's
Report
Abstract: This report by the Slovenian Rarities Committee presents records of rare bird species in Slovenia in 2017, with some addenda for previous years. The numbers in brackets refer to the number of records (first number) and individuals (second number) recorded between 1 Jan 1950 and 31 Dec 2016. Since 1 Jan 2013, submission to the Committee has been required for 37 additional species, 17 of which are regional rarities. Records of these species are not numbered, since records from previous years were not collected by the Committee. The Barnacle Goose Branta leucopsis was first recorded in Category A, in addition to previous Category D and E records. Other notable observations were the third record of Red-breasted Goose Branta ruficollis, fifth records of Lammergeier Gypaetus barbatus and Pomarine Skua Stercorarius pomarinus, and seventh records of Greater Blackbacked Gull Larus marinus and Red Phalarope Phalaropus fulicarius. The list of birds recorded in Slovenia (as of 31 Dec 2017) contains 390 species (375 in Category A, 6 in Category B, 9 exclusively in Category C; 4 species are both in Categories A and C). Category D contains 7 species, while Category E contains 39, two of which are classified into Subcategory E*. These two categories are not part of the list.
