<p class="MsoNormal">Dear everyone,<o:p></o:p></p>
<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>
