I couldn't help but notice this one. What is the danger to birds from
antennas? I've been around a number of different antennas, towers, etc,
both temporary and permanent. I haven't seen any evidence of harm to
wildlife.

Our tower (I work for a TV station) has been the site of an annual survey
on this topic. (I hear our station's founder was an avid conservationist
and was very concerned about these bird kills)

Best information I have is that we don't know *what* the danger is, but we
do know that it exists.

That said, we're talking about much larger towers than would ever be
involved in a ham DXpedition!

I suppose there's a risk to small rodents (mice, squirrels, etc.) because
the tower makes an excellent perch for birds-of-prey!

Seriously, I suspect the concern isn't as much that the antennas
themselves will harm wildlife, as that amateurs will disturb habitat as
they erect those antennas.
