Well, there's another problem with using your car's exhaust to gas the
birds - the car produces a lot of other nasties that would cause the
birds distress, apart from cooking them.

What do you mean by "direct control"?  I don't think that shooting is
really ever effective, and probably attracts a (shall we say) different
type of person willing to help with the problem.  Poisoning is rather
haphazard as well.

On a more personal note, I can't believe I'm having a serious discussion
about offing these poor things!  I understand that it's probably
necessary, but the cynic in me would believe that it's never going to be
done - it's too offensive to the general public.  I can imagine Today
Tonight or some other trashy show crucifying the trappers.

With regards to gassing, I believe carbon monoxide is fairly effective
and painless (after all, people use it when offing themselves), and
the people I've talked to who've used the method for feral control
said it seemed the least cruel.  It tricks the body's mechanisms by
appearing to be oxygen gas molecules, and binds to haemoglobin in the
same way.  Once bound it never unbinds, so eventually the body runs
out of blood carrying oxygen.  One caution - if you plan to use your
exhaust pipe to produce the gas, make sure there is a pipe, or baffle,
or something to take the heat out of the exhaust fumes, because you
could end up cooking the poor creatures rather than gassing them.

With regards to the trap, I believe older designs required a "Judas"
bird inside them to encourage Mynas in.  I don't know if the new trap
requires this, or how they might have got around it.

My personal feeling is that direct control rather than trapping would
be more effective, however I do understand that in some urban areas
trapping is by far the most preferable option.
