Abstract The aim of the study done in 2011 and 2012 was to identify the number of breeding bird species, to provide population estimates as well as to evaluate the conservational importance of Škocjan Caves Park for birds. Common bird species were surveyed using the territory mapping method. Rare species and nocturnally active species were surveyed using species-specific methods: observation, the playback method and the line transect method. 81 species were registered, 49 of which bred within the boundaries of the Park. The most abundant breeding species were Blackcap Sylvia atricapilla (260-320 breeding pairs), Robin Erithacus rubecula (250-310 breeding pairs), Blackbird Turdus merula (230-280 breeding pairs), Chaffinch Fringilla coelebs (230-280 breeding pairs) and Marsh Tit Poecile palustris (200-240 breeding pairs). Qualifying species for the Special Protected Area (SPA) Kras (SI5000023) also bred within the Park: Peregrine Falcon Falco peregrinus, Nightjar Caprimulgus europaeus, Scops Owl Otus scops and Woodlark Lululla arborea. Eagle Owl Bubo bubo was also registered, but breeding attempts during the study period were unsuccessful due to the negative influence of several factors. One of the largest colonies of Alpine Swifts Apus melba, a rare and localized species in Slovenia, is also of conservation concern.

Abstract Between April 2007 and April 2008, 40 systematic waterbird counts were conducted on the Drava River between Lake Maribor and the Melje Dam (length 8.5 km, area 155 ha) to determine the specific composition, abundance and seasonal dynamics of bird occurrence. Between October and May, counts were conducted every week, whereas between June and September they were carried out once every two weeks. In total, 26,803 individuals of 30 species were counted. The number of waterbirds and diversity of species were the highest from late December to late February, when more than 1,000 individuals were regularly present in the area. Waterbirds were distributed along the river unequally, with the highest number of birds present yearround in the city centre and in the first counting sector of Lake Maribor. The Mallard Anas platyrhynchos and Mute Swan Cygnus olor were recorded during every count, while occurrence frequency was greater than 50% in another 10 species. Dominant species in terms of percentage composition were Mallard, Black-headed Gull Chroicocephalus ridibundus, Coot Fulica atra, Mute Swan, Pochard Aythya ferina and Tufted Duck Ay. fuligula. Mute Swan and Mallard were the only breeding waterbirds in the study area. Both the total number of waterbirds and the highest daily total in the first two counting sectors were greater between October and March 1992/93 than in our study. The decline in numbers was the greatest for Mallard, Pochard and Tufted Duck, while an increase was noted in Mute Swan and Yellow-legged / Caspian Gull Larus michahellis / cachinnans. The total number of waterbirds and the number of some species in the study area were significantly higher than expected solely based on its length compared to the length of the lowland Drava in Slovenia (125.7 km). The study area is conservationally important for Pochard, Tufted Duck and Black-headed Gull

Abstract In 2013, 73,529 birds of 161 species were ringed in Slovenia, with 114 finds from abroad, 73 finds of foreign-ringed birds and 1580 local finds. The most numerous ringed species were Blackcap Sylvia atricapilla and Barn Swallow Hirundo rustica, while among ringed nestlings Great Tits Parus major and Blue Tits Cyanistes caeruleus prevailed. The most numerous species among recoveries was the Mute Swan Cygnus olor with probably the oldest swan recorded in Slovenia so far, a 25-year-old female. The longest distance recovery concerned a Sedge Warbler Acrocephalus schoenobaenus from Norway (2,801 km). Of interest among local finds is the longest recovery distance (122 km) recorded for Ural Owl Strix uralensis in Slovenia so far. In 2013, two rare species for Slovenia were ringed, Yellow-browed Warbler Phylloscopus inornatus (2 individuals) and Siberian Rubythroat Calliope calliope, which was the first record for Slovenia.

Summary This report by the Slovenian Rarities Committee presents records of rare bird species in Slovenia in 2013, 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 2012. Since 1 Jan 2013, submission to the Committee is 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. Four new species were recorded in category A: White-headed Duck Oxyura leucocephala, Baillon’s Crake Porzana pusilla, Audouin’s Gull Larus audouinii and Siberian Rubythroat Calliope calliope. Three species, Helmeted Guineafowl Numida meleagris, Chukar Alectoris chukar and Common Bulbul Pycnonotus barbatus, were added to category E. Other notable observations were the second and third records of Bewick’s Swan Cygnus columbianus and fourth record of Dalmatian Pelican Pelecanus crispus. The list of birds recorded in Slovenia (as of 31 Dec 2013) contains 384 species (369 in category A, 7 in category B, 8 exclusively in category C; 4 species are both in categories A and C). Category D contains 6 species, while category E contains 33. These two categories are not part of the list

Summary In 2014, the International Waterbird Census (IWC) was carried out in Slovenia on 18 and 19 Jan. Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 268 observers took part, 413 sections of the rivers and coastal sea with a total length of 1395.1 km and 226 other localities (178 standing waters and 48 streams) were surveyed. Altogether, 45,346 waterbirds of 62 species were counted. This is the lowest number of waterbirds recorded after the 1997 and 1998 censuses. The greatest numbers of waterbirds were counted in the Drava count area, i.e. 20,217 individuals (44.6% of all waterbirds in Slovenia). By far the most numerous species was Mallard Anas platyrhynchos (43.0% of all waterbirds), followed by Black-headed Gull Chroicocephalus ridibundus (10.1% of all waterbirds), Coot Fulica atra (7.9% of all waterbirds), Yellow-legged Gull Larus michahellis (6.0% of all waterbirds) and Cormorant Phalacrocorax carbo (4.6% of all waterbirds). The number of 1,000 counted individuals was also surpassed by Mute Swan Cygnus olor, Pochard Aythya ferina, Tufted Duck Ay. fuligula and Teal An. crecca. Among the rarer recorded species, the Black Stork Ciconia nigra (registered for the first time during the January Waterbird Censuses; only the second winter record in Slovenia), Cattle Egret Bubulcus ibis and Flamingo Phoenicopterus roseus (both registered only for the second time during the IWC) should be given a special mention. Numbers of the following species were the highest so far recorded during the IWC: Shelduck Tadorna tadorna, Muscovy Duck Cairina moschata, Shoveler An. clypeata, Redthroated Loon Gavia stellata and Pygmy Cormorant Phalacrocorax pygmeus. Also, the total number of C and E category species/taxa was the highest to date, although still quite low with 70 individuals. Numbers of the following species were the lowest so far recorded during the IWC: Cormorant, Little Grebe Tachybaptus ruficollis and Green Sandpiper Tringa ochropus

Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 268 observers took part, 413 sections of the rivers and coastal sea with a total length of 1395.1 km and 226 other localities (178 standing waters and 48 streams) were surveyed. Altogether, 45,346 waterbirds of 62 species were counted. This is the lowest number of waterbirds recorded after the 1997 and 1998 censuses. The greatest numbers of waterbirds were counted in the Drava count area, i.e. 20,217 individuals (44.6% of all waterbirds in Slovenia). By far the most numerous species was Mallard Anas platyrhynchos (43.0% of all waterbirds), followed by Black-headed Gull Chroicocephalus ridibundus (10.1% of all waterbirds), Coot Fulica atra (7.9% of all waterbirds), Yellow-legged Gull Larus michahellis (6.0% of all waterbirds) and Cormorant Phalacrocorax carbo (4.6% of all waterbirds). The number of 1,000 counted individuals was also surpassed by Mute Swan Cygnus olor, Pochard Aythya ferina, Tufted Duck Ay. fuligula and Teal An. crecca.

Bibliografija vključuje vse prispevke od letnika 21 (začetek z zvezkom 98/99) do prvega zvezka letnika 34 (156/157). S tem pokriva dosedanje obdobje, ko je revija Acrocephalus tudi dejansko postala mednarodna, z uradno navedeno možnostjo objave prispevkov v slovenščini ali angleščini. Prispevke od prve do 100. številke obravnava bibliografija Acrocephalusa 1980– 2000, objavljena v 101. številki (Tome 2000). Bibliografijo sestavljata kazalo avtorjev in kazalo vrst. V kazalu avtorjev so prispevki razvrščeni po abecednem redu glede na prvega avtorja. Imenu avtorja ali avtorjev sledi naslov prispevka v originalnem jeziku, v oklepaju pa je prevod naslova v angleški oziroma slovenski jezik (jezik povzetka). Pri prispevkih v rubriki Iz ornitološke beležnice je samo naslov v originalnem jeziku (angleško oziroma slovensko ter latinsko ime vrste), prispevki pa so alinejsko ločeni po državah. Nato sta navedena številka zvezka in strani prispevka (celoten obseg). Letnica izida in letnik posameznega zvezka sta predstavljena v tabeli 1.

Abstract Several bird species utilize artificial structures for communal roosting. Between 26 May and 28 Jun 2012, the selection of buoys and times of departure by Mediterranean Shags Phalacrocorax aristotelis desmarestii were studied at three communal roosts within shellfish farms in the Bays of Sv. Jernej (Debeli rtič), Strunjan and Piran (Sečovlje). A total of 3,110 buoys were counted and categorized into two groups according to their shape (horizontal and vertical) and colours. The black horizontally floating buoys were of two types (barrelshaped and oval). The Shags chose to utilize the horizontally floating buoys only, most often black and white in colour. Owing to their poorer stability and smaller standing surface, the vertically floating buoys are clearly unsuitable for them. The highest share of Shags with regard to the number of buoys of separate types was registered on black barrel-shaped buoys. As the percentage of occupied buoys was similar at all roost sites (36-39%), it was deduced that Shags distribute evenly among roosts, regardless of the number of individuals present in the Slovenian sea. At the larger roost at Debeli rtič, the percentage of adult individuals (73.5%) was greater than at Strunjan (42.5%). This could be due to the competition for better places, given that competitively stronger individuals select safer larger roosts. Between 5.42 and 9.00 hrs, 53.3% and 69.1% of Shags departed from the roost sites at Debeli rtič and Strunjan, respectively, with the majority of departures recorded between 7.50 and 8.30 hrs. They left their roosts mostly individually (48.7%) or in pairs (23.3%), at Debeli rtič predominantly in the SW (58.9%) and W (16.9%) directions, and at Strunjan in the NE (42.3%) and N (38.5%) directions.

Abstract This treatise investigates the poorly studied bird fauna of Mitidja Plain (Northern Algeria), with particular notes on the occurrence and expansion of new and alien species. Direct observations, supported by ornithological surveys carried out by Progressive Frequential Sampling (PFS), a version of a point count method, have allowed us to identify 125 bird species. These represent 31% of all species known from Algeria. The species recorded belong to 14 orders, 39 families and 37 genera. According to their biogeographic origins, 36 are Mediterranean, 32 Palearctic, 24 Holarctic, 17 European and 16 of European-Turkestani origin. The Mitidja Plain holds 60 resident-breeder species (48% of all registered species) and is a transit zone for many migratory species (summer and winter migrants constituting 20% and 14% of the total, respectively) and occasional visitors (RA = 12%). Among recently expanding species (introduced or local), the Collared Dove Streptopelia decaocto and Wood Pigeon Columba palumbus, sampled by the spot-mapping method, experienced a very rapid population growth. The first observations of the former were made in 1996 in Algiers. Its numbers experienced a steep increase after 2002, starting from 5.75 pairs/10 ha to reach up to 31.5 pairs/10 ha in 2006. The same applies for the Rose-ringed Parakeet Psittacula krameri, surveyed by direct-count at roosting sites. This species has been able to increase and reproduce since its first introduction into the wild in 1996. The increase in study species populations, especially the Rose-ringed Parakeet, may derive from good weather conditions that favoured the species through providing better feeding conditions, thus high reproduction outcomes.
