Calling birds bad???

["Larry Sirvio" lsirvio]

Lou, and others. 
The birding community has had a lot of discussion about calling in birds with 
recordings. Many birders do it. Many birding guides do it as well. The 
consensus seems to be that calling birds is not so bad as long as it is not 
overdone. Common sense should prevail. Sometimes that is in short supply. 
My theory is that birds have evolved for thousands and thousands of years 
hearing the calls. This is something they have experienced all of their lives 
and should not bother them.

Just another opinion.
