Abstract:: Fledgling mass can have great influence on individual’s life history and reflects the availability and quality of food in the breeding territory. Thus growth curve is used to compare the difference in the quality between different ecological conditions. The aim of the study was to fill the knowledge gap on nestling growth in Great Tit in Slovenia, to determine the influence of altitude on it and to present a tool for estimating age of nestlings and key dates in breeding phenology of Great Tit. Great Tits young were monitored using nest-boxes at three locations between years 2010 and 2012. At two locations nest-boxes were placed on three separate altitudinal belts. Weight growth curve was compared with the curves from other parts of Europe. Growth curve from Slovenia differs in growth parameters from other European populations but falls within their range. Difference in growth parameters between separate populations probably comes from the difference in ecological conditions. When comparing three altitudes weight parameters of hatchlings were similar at lower and middle but different at upper altitudes indicating that weigh growth changes with the altitude. Lower food abundance that comes with rising altitude may be offset by lower competition through lower breeding density (hence similar growth parameters in lower and middle altitude), but not past certain altitude. Weight parameters are useful when comparing different populations, but wing-length is better in determining the age of young in the nest

Title:Rast mladičev velike sinice Parus major s primerjavo med nadmorskimi višinami
Abstract:Masa mladičev v gnezdu je pomemben dejavnik, ki ima močan vpliv na življenje osebka. Masa mladičev v gnezdu odseva dostopnost in kvaliteto hrane na gnezdišču in je zaradi tega dober pokazatelj stanja v okolju. Namen raziskave je bil zapolniti vrzel v znanju o rasti velike sinice na območju JV Evrope ter o pomenu nadmorske višine na rast mladičev. Hkrati bodo rezultati lahko koristili tudi kot orodje za določanje starosti mladičev velike sinice v gnezdu. Meritve mladičev velike sinice v gnezdu so bile opravljene na treh lokacijah med leti 2010 in 2012. Na dveh so bile gnezdilnice postavljene na treh ločenih nadmorskih višinah. Rastna krivulja za maso se razlikuje od krivulj iz ostalih delov Evrope vendar je znotraj njihovih meja. Razlike verjetno izhajajo iz različnih ekoloških razmer v okoljih. Rast mase je podobna med spodnjim in srednjim ter različna od zgornjega višinskega pasu. Podobnost na spodnjih višinah je verjetno posledica kompenzacije manjše količine plena z nižjo konkurenco zaradi nižje gostote gnezdečih parov. Kompenzacija pa je uspešna le do določene nadmorske višine, nad to pa se zmanjševanje količine hrane pozna na počasnejši rasti mladičev. Rast mase je uporabno orodje za primerjavo med populacijami, dolžina peruti pa je boljše orodje za določanje starosti mladičev v gnezdu.
