| Popis: | In this work we present some of the data about the nesting ecology of the White-tailed Eagle (Haliaeetus albicilla) collected during 2009-2018 in the Danube Delta Biosphere Reserve and its surroundings. A total of 144 different nests (occupied, unoccupied and destroyed) were recorded in this period. We also recorded 7 breeding pairs (territories) whose nests could not be identified. The preferred tree species for nesting were Salix alba with 63% of all identified nests, 17% were in Populus alba, Populus x canadensis hibrid 15%, 3% in Alnus glutinosa, 1% in Tilia tomentosa and 1% in Quercus robur. The nests were located in the tallest trees available on the site and were placed at heights between 5 and 24 meters. 67% of these were above 13 m of the ground, while 33 % below. The White-tailed Eagle nest site selection may be a response both to tree availability in the foraging habitat as well as food supply. |
