| Popis: | In the autumn 2013 were set up 50 nest boxes for increasing of density of the Common Goldeneye population (Bucephala clangula) in Třeboň region. The main objectives of this study were to check the nest boxes after breeding season and analyse the results. These nest boxes were checked in the July 2014 and 2015. In the spring 2015 were set up 2 mobile scouting cameras to the selected nest boxes. There was also monitor the occurrence of the Common Goldeney on the Naděje fishpond system and Prátr fishpond system by counting. The Naděje fishpond system is created by 16 different sized fishponds and it is situated approximately 8.5 km to the south of the town Veselí nad Lužnicí. The Prátr fishpond system is situated approximately 1 km to the south of the town Třeboň and it is created by 9 fishponds. The monitor was realised in term from 17. 3. 2015 to 27. 7. 2015. The other species of water birds were also counted. In the year 2014 10 nest boxes were occupied and in the year 2015 17 nest boxes were occupied. The nest boxes which were located on the fishpond´s islands were preferred. Both of the mobile scouting cameras recorded European Pine Marten (Martes martes) devastating the nest. The Common Goldeneye was occurred on the both fishpond systems in 2015. In the year 2015 was observed the female of the Common Goldeneye with 8 ducklings on the Prátr fishpond system. |
