I recall a BBC report a few years ago...also picked up by
the NY Times, btw, which indicated that the common house cat
in the UK was the greatest single predation source for 
british songbirds.  Moreover, it estimated that they were
responsible for reducing the songbird population by something
like 40%. 

Even THAT sounded a bit farfetched, but I suppose it could be 
true, as I have no sense of their population of predatory birds.

With respect to RF field density and bird kills, I was thinking
specifically of TV broadcast stations and radar.  ERP's of 
megawatts in the UHF band, in the case of the former, and 
at L and X band in the case of the latter.   

Consider that the ordinary microwave is something like 700w to
1 kw, around 800MHz.  Not sure of that frequency.

There is, after all, no licensing requirement for journalists.
All one can do is factually correct the errors and hope for the 

BBC world service has a reputation for following through on 
e-mail complaints, though.  K3NA's post may be worth following
through on.

Stations", and lot's more.  Call Toll Free, 1-800-333-9041 with any questions
