Abstract In 2017, the Slovenian bird ringing scheme concluded 90 years of continuous ringing in the country. In 2017, we collected data on 176 bird species. We ringed 79,886 birds of 164 species, recorded 177 recoveries of birds ringed in Slovenia and found abroad, 295 foreign recoveries in Slovenia and 2,209 local recoveries. The most ringed species were the Blackcap Sylvia atricapilla and Great Tit Parus major and, among pulli in the nest, the Great Tit, White Stork Ciconia ciconia and Barn Swallow Hirundo rustica. In 2017, 12 colour ringing schemes were active in Slovenia. In the 2012-2017 period, the number of recoveries of birds ringed in Slovenia and found abroad increased significantly due to colour ringing, especially regarding the waterbirds. With colour ringing, the likelihood of recoveries is considerably greater (75.20 ± 91.36 recoveries per 100 ringed birds) than with metal ringing only (0.11 ± 0.08 recoveries per 100 ringed birds). Among local recoveries, the most frequent were the Mute Swans Cygnus olor and Common Terns Sterna hirundo, and among foreign recoveries the Black-headed Gulls Chroicocephalus ridibundus predominated. In 2017, the first Broad-billed Sandpiper Calidris falcinellus was ringed in Slovenia (Sečovlje salinas), and additional three rare species were ringed as well: the Yellow-browed Warbler Phylloscopus inornatus (Ljubljansko barje), Paddyfield Warbler Acrocephalus agricola (Ljubljansko barje) and Little Bunting Emberiza pusilla (Šentrupert).

Abstract In 2016, data on 176 bird species were gathered during bird ringing activities in Slovenia. A total of 65,711 birds of 165 different species were ringed. Furthermore, 148 recoveries of birds ringed in Slovenia and found abroad, 245 foreign recoveries in Slovenia and 1840 local recoveries were made. The most frequently ringed species was the Blackcap Sylvia atricapilla. Among the ringed nestlings, Great Tits Parus major, Tree Sparrows Passer montanus and White Storks Ciconia ciconia predominated. Considering recoveries of birds ringed or found abroad, the most frequent were finds based on colour rings, especially of Black-headed Gulls Chroicocephalus ridibundus, Mute Swans Cygnus olor and Common Terns Sterna hirundo. As far as local recoveries are concerned, most data were collected for Great Tit and Siskin Spinus spinus. Among rare species, two Yellow-browed Warblers Phylloscopus inornatus were ringed, one Paddyfield Warbler Acrocephalus agricola, one Little Emberiza pusilla and one Black-headed Bunting Emberiza melanocephala, the latter as a singing male, which probably also bred in 2016. The catch frequency of the Yellow-browed Warblers has indeed been increasing in Slovenia in the last 25 years, but this is still a rare and irregular vagrant on autumn migration.

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. The first analysis of ringing sites in Slovenia is given as a baseline for establishing a network of Constant Effort Sites

Abstract In 2015, 170 bird species were recorded during bird ringing activities in Slovenia. We ringed 73,371 birds belonging to 162 species, there were 132 foreign recoveries of birds ringed in Slovenia, 120 recoveries of birds ringed abroad and found in Slovenia, as well as 1964 local recoveries. The most frequently ringed species were Blackcap Sylvia atricapilla and Great Tit Parus major. In ringed nestlings, Great Tits and Tree Sparrows Passer montanus predominated. In 2015, the first preliminary ringing of Scops Owls Otus scops during migration took place, resulting in the highest number of Scops Owls ringed so far. Concerning recoveries of birds ringed in Slovenia and later recorded abroad and birds ringed abroad and later recorded in Slovenia, the commonest were Mute Swans Cygnus olor and Black-headed Gulls Chroicocephalus ridibundus. The longest-distance recovery concerned a Reed Bunting Emberiza schoeniculus found in Sweden (2,144 km away). Among the interesting finds were also the first finds of ringed Pygmy Cormorants Microcarbo pygmeus so far from breeding sites in Hungary. Among rare species, Yellow-browed Warbler Phylloscopus inornatus, Spanish Sparrow Passer hispaniolensis and a pair of Parrot Crossbills Loxia pytyopsittacus were caught and ringed, the latter for the very first time in Slovenia after more than 100 years. An overview of records of the Parrot Crossbill is given herein, as well as analysis of irruptive years of the Red Crossbills Loxia curvirostra between 1980 and 2015, when the probability of boreal Crossbill species occurrence is the highest. According to the ringers’ data, the irruptive years of Red Crossbills in Slovenia were 1984, 1985, 2007, 2008, 2010, 2011 and 2012. The article points to the probability that Parrot Crossbills have been overlooked in the past, since larger specimens of Crossbills were ringed mostly in irruptive years, but no specific bill measurements important for distinguishing between Parrot and Red Crossbill had been taken.

In 2014, 162 bird species were recorded during the bird ringing activities in Slovenia. Of 155 species, 62,275 birds were ringed, and 107 recoveries of birds ringed in Slovenia and found abroad, 148 foreign recoveries in Slovenia and 1395 local recoveries were recorded. The most frequently ringed species were Blackcap Sylvia atricapilla and Great Tit Parus major. As far as ringed nestlings are concerned, Great Tits and Barn Swalllows Hirundo rustica predominated. Considering the recoveries ringed of found birds abroad, the commonest were Black-headed Gulls Chroicocephalus ridibundus and Mute Swans Cygnus olor. The farthest recovery was a Barn Swallow Hirundo rustica found in the Democratic Republic of Congo (5171 km away). Among the more interesting finds was also the so far southernmost recovery of a Sand Martin Riparia riparia found in Israel. Let us also mention the first recovery of a Corncrake Crex crex, which bred and was ringed in 2013 at Planinsko polje (central Slovenia) and was found in the 2014 breeding season in the Czech Republic. Among rare species, two Little Buntings Emberiza pusilla were caught and ringed. After nine years, the Roller Coracias garrulus bred again in Slovenia in 2014 and its nestlings were ringed. The paper also brings the description of the migration route of the first African migrant, the Black Stork Ciconia nigra, marked with a GPS/GSM telemetric device, which migrated across the Adriatic Sea, Sicily and Sahara to Nigeria.

Tree Cavity

Conservation of the biodiversity of the forest ecosystems is becoming one of the priority issues in the forest management. Birds play an important role in the overall life of the forest ecosystem, for instance, as an important component of the trophic chains. Recent studies worldwide suggest decline in the population size and richness of the forest bird species, especially those nesting in the cavity of the forest trees. Special emphasis is placed on the secondary cavity nesters. In contrast to the primary cavity excavators, which are making a tree cavity by themselves, secondary cavity nesters for their nesting use cavities made by the primary cavity excavators or natural cavities formed by gradual wood decay process. In order to maintain bird diversity in the forests with a lack of nesting cavities, installation of the nestboxes is an important strategy in many countries. This applies mainly to young deciduous, coniferous stands, and monocultural plantations and areas afforested with exotic tree species. In this paper, occupation of the nestboxes in the young deciduous stands was investigated. According to some researchers, the colour of the nestbox and its height above the ground could be important factors of the nestbox occupation in some bird species. In this study, a total of 120 standard wooden nestboxes were used (60 green and 60 brown). Nestboxes were installed in pairs on a single tree, at a height of 4.0 to 4.5 m (“high” position) and 2.0 to 2.5 m (“low” position). On the first tree, the green nestbox was in the “high” position, on the next tree in the “low” position and so on. The aim of this study was to determine the degree of occupancy of the nestboxes with a respect to the colour and the position on the tree. Because of the intra- and interspecific competition, only one of the nestbox pair was inhabited. Of the total 60 nestbox pairs, 44 (73.3%) nestboxes were occupied; 35 (79, 5%) by a Great Tit (Parus major) and 9 (20.5%) by a Blue Tit (Cyanistes caeruleus). Great Tits occupied mainly “green” nestboxes (88.6%), with no significant differences in the height position of the chosen nestbox. In conclusion, the colour of the nestboxes is more important factor than the height position on the tree during the occupation of the nestboxes by a Great Tit.

AbstractBackgroundA widely used approach in next-generation sequencing projects is the alignment of reads to a reference genome. A significant percentage of reads, however, frequently remain unmapped despite improvements in the methods and hardware, which have enhanced the efficiency and accuracy of alignments. Usually unmapped reads are discarded from the analysis process, but significant biological information and insights can be uncovered from this data. We explored the unmapped DNA (normal and bisulfite treated) and RNA sequence reads of the great tit (Parus major) reference genome individual. From the unmapped reads we generated de novo assemblies. The generated sequence contigs were then aligned to the NCBI non-redundant nucleotide database using BLAST, identifying the closest known matching sequence.ResultsMany of the aligned contigs showed sequence similarity to sequences from different bird species and genes that were absent in the great tit reference assembly. Furthermore, there were also contigs that represented known P. major pathogenic species. Most interesting were several species of blood parasites such as Plasmodium and Trypanosoma.ConclusionsOur analyses revealed that meaningful biological information can be found when further exploring unmapped reads. It is possible to discover sequences that are either absent or misassembled in the reference genome and sequences that indicate infection or sample contamination. In this study we also propose strategies to aid the capture and interpretation of this information from unmapped reads.

Abstract In 2011–2014, the occupancy of nest-boxes by secondary hole-nesting birds and their breeding success was investigated in pine stands of the Augustów Forest (North-Eastern Poland). In the studied area of 12600 ha, the share of Scots Pine Pinus sylvestris L. in the stands was 92%. On average, birds occupied 54% and bats 3% of the 224–317 nest boxes controlled yearly. Nest boxes were also used by the Pygmy Owl Glaucidium passerinum L. as food caches. In total, broods of nine secondary hole-nesting species were observed, but only four bird species nested in each year of study. The most numerous species, occupying 53–60% of all boxes each year was the Pied Flycatcher Ficedula hypoleuca Pall. The Great Tit Parus major L. occupied 15–24% and the Coal Tit Periparus ater L. 10–12% of available nest-boxes, while the Redstart Phoenicurus phoenicurus L. used 2–7% of nest boxes. The yearly breeding success was highest for tits (Great Tit – 52–84%, Coal Tit – 50–72%) and strongly variable for the Pied Flycatchers – 38–78%. Broods were lost due to predation by martens Martes sp. (38%) and great spotted woodpeckers Dendrocopos major L. (6%) as well as nest competition (2%). The nest-boxes were occupied at a constant rate during the following four years after their exposition. Over 67% of the new nest-boxes were occupied annually which means new nest-boxes (up to 4 years) were occupied significantly more often than boxes older than 4 years.

Incubation Rhythm

Uniparental incubation frequently means that eggs remain unattended for periods where the incubating bird is foraging out of the nest. The determination of incubation rhythms (i.e., the length and temporal pattern of incubation sessions) and the factors which affect them are therefore important to understand life-history trade-offs. We described the incubation rhythm and its temporal variation of a southern European great tit Parus major population, and review previous studies to check for latitudinal trends. In the studied population, females were active (from first exit in the morning to last entrance in the evening) 12.5 h per day, performing incubation sessions (on-bouts) of 26 min and recesses (off-bouts) of 12 min. Thus, they were incubating around 67% of their active day, or 83% of the whole day. Attentiveness (% of time incubating) increased throughout the incubation period, due to shorter off-bouts. The active day was longer as the number of daylight hours increased. We show for the first time in a bird species that attentiveness was constant along a latitudinal gradient ranging from Norway to Spain. Females spend a higher proportion of the daylight hours out of the nest as latitude decreases, compensating incubation time during the longer nights. Off-bouts were shorter in central European populations, increasing towards the north and the south, while on-bouts showed no latitudinal variation.

Conflicting Demands

AbstractIn a number of passerine bird species, mated males sing at dawn and this song activity peaks in the fertile period of the mate. We present the hypothesis that an important function of such dawn singing is to maintain the territory. We suggest that mate guarding and territorial defence are demanding and often mutually exclusive activities. Losing paternity is so costly that males give priority to mate guarding. Males therefore use the early morning period, before their mate emerges from the roost, to claim territory ownership. We report some preliminary tests of this hypothesis from a study of great tits (Parus major). Simulating male intrusion by a playback experiment showed that the resident male was more often absent from central parts of the territory, following the mate, during the periods of nest building and egg laying than during incubation. This supports the assumption of conflicting demands between mate following and territorial defence. From the hypothesis we expected males to spend effort in defending their territory as soon as they were free to do so. Consistent with this prediction, we found that male song activity was high before the mate left the nest at dawn, when she temporarily visited the nest during the day, and when she entered the nest to roost at night. A female removal experiment showed that unmated males, having no mate to guard, sang as much at dawn as mated males. Only one of the eight widowed males succeeded to replace their mate. We discuss some alternative functions of dawn singing in the great tit, such as attraction of own mate, a replacement mate, and extra-pair mates. We conclude that the hypotheses are not mutually exclusive, and song may serve multiple purposes.

We analyzed the synapsis and recombination between Z and W chromosomes in the oocytes of nine neognath species: domestic chicken Gallus gallus domesticus, grey goose Anser anser, black tern Chlidonias niger, common tern Sterna hirundo, pale martin Riparia diluta, barn swallow Hirundo rustica, European pied flycatcher Ficedula hypoleuca, great tit Parus major and white wagtail Motacilla alba using immunolocalization of SYCP3, the main protein of the lateral elements of the synaptonemal complex, and MLH1, the mismatch repair protein marking mature recombination nodules. In all species examined, homologous synapsis occurs in a short region of variable size at the ends of Z and W chromosomes, where a single recombination nodule is located. The remaining parts of the sex chromosomes undergo synaptic adjustment and synapse non-homologously. In 25% of ZW bivalents of white wagtail, synapsis and recombination also occur at the secondary pairing region, which probably resulted from autosome−sex chromosome translocation. Using FISH with a paint probe specific to the germline-restricted chromosome (GRC) of the pale martin on the oocytes of the pale martin, barn swallow and great tit, we showed that both maternally inherited songbird chromosomes (GRC and W) share common sequences.
