Anyone (and most of the rest) who experienced car sickness knows
that the difference between what the eye sees, and the balance says,
causes nausea.
Assuming that pigeons have a sense of balance, and a magnetic
sense
of direction, if there was a way to make them disgree then it might
cause
discomfort.
So, a magnetic field with rotating direction might severely disrupt
their
activities.
In humans, 1 second cycles of movement are quite effective. A
magnetic field with rotation frequency of 1s would be a starting
point.
A huge 3-phase motor winding type device without the rotor might do
the trick. The magnetic field would not need to be strong; just similar
magnitude to that of the Earth. I wonder if a complete building could
be
protected?
As a side experiment, all humans who have remnant sensitivity, may
suffer similar nausea.

So, a way of making the feathered rats spew from both ends ?... works for me [+] |
|

Kill them. Kill them all. Spare not even the children, lest the evil persist ... |

I quite like pigeons. They're smarter than some people of
whom I can think. |
|
| |
They're also partially edible. |

Linky. Remembered this from me London days. |

beautiful sweet clever birds. |
|

Yes, until they get out of hand. <link> |

// beautiful sweet clever birds. // |
|

No, [po], that's parrots. Pigeons are disgusting, verminous, disease-carrying scavengers with the intellect of doorknobs. |

Or is that Belgians ? Could be either ... |
|
| |
They won more wartime medals than any other anmals |
|
| |
Didn't know that Belgians had won that many medals ... what for ? Chemical warfare ? That's just the normal smell of the drains .... |

If a pigeon was running for president of the USA, I would vote for it. |
|

//They won more wartime medals than any other

|

Yes, but only because the fool who decided to
award medals to animals didn't have the idea until
horses were no longer a major part of the military.
It was pretty much a case of having to award the
medals to either a pigeon or the most recent
officer's lunch (sometimes both together). |
|
| |
It was also discovered, sadly too late, that a
pigeon with two ounces of bronze pinned to its
chest was severely impaired in the flying
department. |
|
| |
Worked well as body armour, though. |
|
| |
Not so much, though. The only difference would be
a 2" diameter hole through the pigeon, as opposed to
a 7.6mm hole. |
|
| |
That sounds like a cue for a practical test, and possibly a song, too ... <link> |
|
| |
What [xenzag] said. And then some. |
|
| |
// 2" diameter hole through the pigeon // |
|
| |
An impromptu test using a 60mm diameter x 3mm thick brass disk, a small frozen chicken (fully defrosted) and a .30-06 FMJ round (balistically comparable to the German 7.92mm round) at a range of 50m does not result in a 60mm diameter hole through the chicken. Not unexpectedly, it simply results in no chicken whatsoever. |
