 | | About 550 pairs of birds of the family Ardeidae nest on the Swan islands in the Karkinit Gulf of the Black Sea, the most numerous colonies being of grey heron and little egret. |
 | | Analysis of the life cycles of the recorded trematode species, and study of different invertebrates near the Swan Islands revealed that the most frequent food for Ardeidae in this region is freshwater fish, sea fish, more rarely Crustacea and, very rarely Mollusca. |
 | | Ardea cinerea and Egretta alba are invaded by Pygidiopsis genata, Cryptocotyle concavum, Cryptocotyle lingua and Maritrema subdolum, a clear indication that on the Swan Islands thay prefer sea habitats. |
