As you may know, weekend in Iran and some Islamic countries are Thursday and Friday. At Friday,We had a small trip to a artificial wetland. This shot had taken by my friend (Mr. Javad Dellpassand) in new habitat of swans.
Six years ago, a small colony of whooper swans (Max. 500 birds) had migrated to the Caspian south basin in a new habitat in SURKRUD rice farm. After that, population size increased every winter. On the other hand, some bird lovers start a new activity for feeding them because it seems swans are more than carrying capacity of mentioned habitat. Last year, it became about 10000 swans (more and less).
Actually, another group of specialist think people arrive in a non ecological manipulation by feeding them because they believe it maybe cause an artificial changes in flyway and something like that!
Please look at the image and if possible, kindly give me your opinion about diffident bill patterns.
P.S: most of swans population show left pattern and some of the are intermediate.
