On
the evening of August 7, 2007, we were outside of
the house talking when we noticed this massive
flock (swarm) of birds that looked similar to barn
swallows. As the sun declined, they all
started to zoom, like fighter pilots, into our old
chimney.
We
had never seen such a site and my Dad has been
around here for close to seven decades!
Dad
did some research and learned that the birds that
were using the chimney as a night-time roost are
Vaux's Swifts. They are a very interesting
and beneficial bird.
We
are very close to their Northern most migration
point of British Columbia. In the fall, they
migrate back down to Central America and
Venezuela. The aerobatics that they perform
nightly is a very cool show.
They
are extremely beneficial birds to have around.
Two parents and their noisy offspring will consume
over 12,000 flying insect pests every day. While
in flight, they devour nearly one third of their
own weight in flying insects (mosquitoes, gnats,
biting flies, termites, etc.), everyday!
Now
comes the bad news. Our old farmhouse is
heated exclusively with wood. The old
unlined brick chimney that they have found is
slated to be cleaned and lined with stainless
steel prior to this (2007) heating season.
We will wait until they leave to perform the work
but that means that next year, they will not have
a home on our farm.
So,
using the research my Dad performed, I found a
solution to attract them back. We love
insect eating birds here on the farm!
The
picture to the left is of a model Swift Tower at
the Hornsby Bend Wastewater Treatment Plant near
Austin, Texas. They use them as an
informational Kiosk as well.
This
is the model that we will use to construct habitat
here on the farm. We hope to have one to
three constructed by next spring's migration.
The

constructing the towers and the next two links
have step-by-step photographs of the process. |
