  1. 1. Exposure and Carriage of West Nile Virus in feathered Iberian Scavengers

    Master-uppsats, Uppsala universitet/Institutionen för ekologi och genetik; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ivan Marin Cacho; [2022]
    Nyckelord :West Nile Virus; Raptors; Vultures; Scavengers.;

    Sammanfattning : Scavenging bird of prey have been abundant throughout the Mediterranean region for years, establishing a food acquisition relationship with human activities, their characteristics make them especially suitable for the recognition of dangerous environmental conditions. The West Nile Virus (WNV) considered the most widespread arbovirus has been previously discovered in our 3 species of studio. LÄS MER

  3. 2. Eyes in the nest : breeding phenology of Golden Eagles characterized using remote cameras

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Richard Larsson; [2020]
    Nyckelord :Golden eagle; breeding; Aquila chrysaetos; camera trap; phenology; Sweden;

    Sammanfattning : In situ monitoring of raptor breeding ecology with field personnel is costly, difficult and demanding. Installing camera traps in raptor nests can provide researchers with diverse information and long-term monitoring. Furthermore, it allows for relatively cheap data collection. LÄS MER

  4. 3. Dietary preferences of Golden eagles (Aquila chrysaetos) in Sweden : a camera trap approach

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Tomas Melin; [2020]
    Nyckelord :Aquilla chrysaetos; breeding; camera trap; Golden eagle; nestling; prey; Sweden;

    Sammanfattning : Food availability and suitable habitat are necessary for reproductive success of raptors. Monitoring these variables may therefore provide important insights on fitness and population dynamics of species such as the golden eagle (Aquila chrysaetos), which are often very difficult to monitor.

  5. 4. The effect of urbanization on the characteristics of bird populations : current situation and future aspects

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Linnea Östermark; [2017]
    Nyckelord :urbanisering; biodiversitet; fåglar; egenskaper;

    Sammanfattning : Tack vare människans allt mer progressiva utbredning utsätts många djurarter för nya miljöer som är helt skilda deras naturliga förhållanden. Fåglar är en av de grupper som har påverkats i allra högsta grad. En gradvis avtagande biodiversitet av fågelarter blir ett av resultaten av urbaniseringen. LÄS MER

  7. 5. STUDY OF REQUIREMENTS FOR POST-CONSTRUCTION AUTOMATED BIRD MITIGATION SYSTEMS FROM STAKEHOLDER’S PERSPECTIVE

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Veaceslav Crasilşcic; [2016]
    Nyckelord :wind power; avifauna; collision risk; birds; raptors; golden eagles; white- tailed eagles; bird mitigation systems;

    Sammanfattning : The expansion of wind power comes with additional risks for bird populations, one of which is the collision with wind turbine components, mainly the rotating blades. In order to mitigate this risk, few systems on the market propose solutions with modules that deter the birds from the wind turbine or trigger the temporary shutdown of the turbines. LÄS MER
