Most of the old Telinga clients in Sweden say that "it's more quiet nowadays".
So I made a phone call to
http://www.sofnet.org/ottenbyfagelstation/start/ which is the most
scientific center for counting birds in Sweden and they verified that
there has been a clear drop of birds (not all species, of course)
during a 20 year period.
It would be interesting to get facts about it.
Is it http://en.wikipedia.org/wiki/Silent_Spring that we hear?
