Swifts
used to nest in the massive trees found in ancient forests.
Nowadays they will sometimes breed in structures like
motorway light gantries, or water towers, if they can find a space in
them to make a nest. So why not create a special nest
colony for them on top of a pole or a tower?

A
brilliant opportunity! On the
left, a magnificent early 20th Century water
tower in Berlin. This was fitted some years
ago with a good number of Swift nest boxes,
and for some time the colony did well. In
recent years Swifts however have failed
to breed there. No one knows why this is
so, though they are still present in the
sky above the neighbouring apartment blocks.
On
this tower, for architectural and aesthetic
reasons, the nest boxes were bespoke, mounted
internally and made from plywood. At less
sensitive sites commercial readymade concrete
nest boxes may be used with great ease and
economy.
It is always worth fitting
Swift nest boxes to such sites, as they
have several important advantages; longevity,
security, centralised management, privacy,
peace and quiet, good opportunites for observation
and CCTV/web cam installation, excellent
possibilites for educational activities
involving residents and local schoolchildren
and of course, good publicity for the utility
company involved.

Perfect
for Swifts! The
bleak, landscape of Ashford International
Rail Station in Kent. Such
places are ideal for establishing Swift
colonies as the Swifts will find their food
easily over the lush surrounding farmland
and ponds of Romney Marsh. The steel lamp posts and
pylons used at this site are suitable
for conversion to support Swift colonies.
The type illustrated below folds down for
maintenance, a useful feature removing the
need for expensive access equipment when
checking the boxes are still sound and fit
for purpose.
On the right one can
see three light arrays, two on posts and
one on a pylon. The two taller ones are
suitably high for use by Swifts. A pole
colony could be fitted to the taller of
the two lamp posts (though obviously it
could no longer function as a lamp post)
while individual Swift nest boxes could
very easily be sited on the pylon, together
with CD Swift call players, as power is
readily available.
The hinge
at the base of the lamp post permits easy
lowering for maintenance.

Minimum height
for a Pole or Tower colony is 7 metres, but the higher
the better, and safer. Care has to be taken that the
site selected is not vulnerable to vandalism. Any concentration
of birds may present an attractive target for anti -social
behaviour. Nest places should therefore be sited as
high as possible and at sites which are either unattractive
to vandals or else secure. Industrial estates, electrical
switching yards, MOD sites, nuclear and other power
stations, hospitals, mobile phone masts, railway sidings,
factory towers and chimneys all present good opportunities
for siting pole and tower colonies, while social housing
estates, brownfield sites, and unsecured sites in general
should probably be avoided.

N.B. It is essential to have an engineer check the plans
for any proposed Swift Tower or Pole for structural
soundness well before any work starts.
