Main aim is monitoring of the population of Golden eagle (Aquila chrysaetos) in this area, confirming of presence of breeding pairs in their home range, approving the occupancy of known nests and looking for the new nests and breeding sites. Weather was not optimal during the whole time of monitoring. The rainfall ended just after our arrival on Saturday, the sky was halfly cloudy on Sunday with continuos fog above 1000 m a.s.l.. On Monday and Tuesady was sunny with morning fogs. In this year we controlled home range of 6 pairs of golden eagles, while we encountered adult birds at 5 sites. We found occupied nests with incubating females in 4 cases. One pair was not breeding (Gstatterstein) most probably due to mortality of old female which was replaced by subadult female, which was several times observed together with old male. We found new breeding site with 3 unoccupied nests, where we expect new pair of eagles on the border of national park. We controlled also nest in gorge near Radmer which was not occupied. Due the lack of time, we did not monitor this site for longer period. Observation points, from which it is possible to see the nests, are located in WGS 84 system of coordinates. It is possible to see coordinates in EXIF datas of photographs. In attached CD you can find originals of photodocumentation and GIS layers in shp format. At most of the nests, their coordinates are estimated from digital maps provided by NP Gesause. Some of the photos are with GPS coordinates which are transferred to kml format, which can be viewed in Google Earth.
