The research requires the public to everything, like counting whooper swans this weekend for example. Anyone who wants to can help.
On Saturday and Sunday are implemented throughout Western Europe, an inventory of whooper swans. It takes place in the framework of a project led by Wetlands International, an organization that works globally to conserve wetlands and their wildlife.
– The inventory of whooper swans takes place every five years. That in this work involve the public also has proven to be a successful and effective grip, says Leif Nilsson, researcher at the University’s biology department.
– Swans, in this case, whooper swans, feel all again.
Whooper swans are now available across the country. It is estimated that there are about 5400 pairs in Sweden, and not just in wetlands and streams, but also in the middle of cultivated land. Remains from machine harvested sugar beets and other crops means set tables for the swans. They have simply changed their original behavior.
– But well into the 1900s, the whooper swan rare in Sweden and other Nordic countries. They were hunted hard. As far as until the 40s and 50s was described species of bird books as a rare breeding bird in northern Lapland, says Leif Nilsson.
