<div class="moz-cite-prefix">Hi Heidi, <br>
<br>
the spikes Susan linked in her post are commonly applied all over
Munich on all sorts of buildings; buildings with more complex
façades are usually netted. As<br>
pigeons are very clever birds it is definitely worth to follow
John's recommendation to remove all nests first. If you apply
these spikes on the ledges, make sure they are set densely enough.
I have spotted some pigeons near our museum which are smart enough
to balance themselves in between those spikes if they are too
widely spaced.<br>
<br>
Scaring them off (loudly clapping your hands and shouting at them
in combination with chasing them off with water loaded super
soakers) usually works also very well - pigeons have a very good
memory and usually avoid areas where they witnessed really scary
situations (The house of my neighbour is invested with pigeons
which have been breeding there since 2-3 years. Then they tried to
spread; immediate neighbours used the spikes, when I saw them in
our gable I scared them off - they never came back).<br>
<br>
If the façade should be too complex or too high, hiring a falconer
might be another option. This also helps against impertinent
crows.<br>
<br>
Best of success!<br>
Dirk<br>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Ditsong: National Museum of Natural
History is an old building with wide window ledges. Recently
we have noticed that the pigeons will nest, roost and sit on
the ledges making a huge mess. Some of the ledges have
spikes, but this is an even bigger attraction for the
pigeons. The mess has become a problem as the pigeons now
flock to this specific building. Our resident cats we think
have enough mice and rats to contend with and the pigeons
mostly stay up on the fourth floor roof or window ledges.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a solution for this problem,
please any advice will do.<o:p></o:p></p>
