HISTORIC
SITE INSTALLATIONS
Installing a bird exclusion system for a Historic Site
involves a variety of factors: (1) preservation of the Historic Site, (2)
Historic restoration, conservation and maintenance, (3) selection of proper
bird exclusion system, (4) effectiveness and longevity of the bird exclusion
system and (5) impact that the bird exclusion system has on the surrounding
Historic landscape. The preservation of
historic and prehistoric sites can contribute to our appreciation and
understanding of our Nation’s cultural and political history.
Bird Exclusion Goals for
Historical Buildings
 Exclusion of
target birds from all areas to prevent damage to building and/or structure due
to the corrosive nature of bird droppings and to preserve the original
aesthetics of the building.
- To
preserve the original aesthetics of the building, efforts should be made
to limit and/or avoid marking, drilling, etc. to the building.
- The
chosen exclusion system must achieve the following:
- Have
a minimal visual impact.
- Obtain
the level of exclusion necessary to be effective, i.e. identifying the target
species:
- Exclusion
of larger birds = few limitations
- Exclusion
of smaller birds = more intricate/specific planning
- Cause
the least amount of structural impact to the original structure.
- Any
holes or marks may compromise the aesthetics and durability of the
original structure.
- If a
device is removed, holes that are left unsealed could lead to damage, i.e.
cracking due to freezing water.
- If
holes that are drilled are not adequately sealed or if the devices are
not properly mounted, the building may experience leaks, cracking, etc.
