[not picking on Mr. Friesen, but]
I have been biting my tongue during this "authoritative" discussion but
feel I have to say this. Unlike European cuckoos, North American
cuckoos very seldom are brood parasites and in my 15 years of birding I
have never heard of them being a problem. Are you folks thinking of
cowbirds? They are a big problem and control measures have been
instituted where they are a threat to endangered species.
