| Preliminary Researching of Ferruginous Duck Ecology. (Aythya nyroca), in the Area of Special Zoo-Reservation "Kopački Rit" and the Fishponds "Podunavlje" in Baranja pdf HR EN | 319 | |
| Summary: This paper deals with prelimenary researhing of ferruginous duck, Aythya nyroca, which has been done in the area ofhunting -forestry ground of "Croatina forestry" in famous special ZOO reservation "Kopački rit" and on thefishponds "Podunavlje" in Baranja, Croatia.Eggs dimensions were measured by metal mobi/e measure and hand pharmaecutical scale of 100 g. and height ofnest from the ground and other parameters by spring meter. Counting was done by census and abundance using binoculars and larger spectives. Ferruginous duck regularly builds nests in Kopački rit and ponds "Podunavlje ". The largest number of nests 85,72% wasfound on the fishpond. Nests were found on so-called "islands ", deposits of ground left after building the fishpond and on "alluviums" of previous Vardarac swamp. "Islands" are overgrown with characteristic swamp vegetation from the slass Phragmitetea Tx. etPrsg. 1942. (Rauš, 1985.). In flooded area of Kopački rit it builds a nest in adventitions roots of old white willows, Salix alba marked as trees with habitus "I" (Getz, 1974.), on the height of´75 - 220 cm from the ground. Mass building of nests was noticed in the second and third decade ofJune, what was confirmed by watching ducling age. In nests were found 2-19 eggs; 9 nests were marked as completed and 1 was in forming. In 3 cases agges ofMallard were found also, Anas platyrhynchos. Watched females had 4-14 ducklings. The siže ofpopulation was 50 pairs (Kopački rit and Ribnjak). Ferruginous duck is a migratorv bird. It comes back to homeland in the beginning of March. First observation, 56 duck, was noticed on March, 8-th 1969. Itleaves in September and October. The latest observation of duck was noticed on December 30-th 1981.,8birds. To preserveferruginous duck in the area in present siže ofpopulation it is neccessary to name thefishpond "Podunavlje" ornithology reservation or include him in special ornithology reservation "Kopački rit" considering that it is close to its borders. | ||
