In an urban environment, when it is cold, wild birds need to be provided
with food if they are to survive. The resident squirrels also need a source
of food but they will destroy the feeders and scatter the bird food if
left to do as they want. These photographs illustrate the effectiveness
of a simple device which doesn't harm the squirrels but defeats their
persistent attempts at wanton destruction and theft.
How its made ...
The bird table is supported on a 25 mm dia. wooden dowel (in effect a
long broom handle) and the the anti-squirrel device is simply an inverted
biscuit tin with a 25 mm hole drilled in the centre of the base. It is
loosely retained by two jubilee clips at a critical height (about 1.1
m). It is protected against the weather with a coat of Cetol, which
is refreshed at the end of the season for a virtually indefinite life.
The dowel is hammered into the lawn and situated in clear space (about
3m all around) so that squirrels can't jump across to the table and predators
such as cats can't hide in wait
... and does it work?
See for yourself. The device worked for many years and never, to our knowledge, let a squirrel past. That is until we moved house and were forced to repair the set up. The subtle changes made quite a difference and when we get time to explain what happened and how we overcame the failure we'll post it here.

The squirrel
has an absolute fascination with the seeds and peanuts and fancies its chances
by shinning up the pole. It soon encounters the obstacle and decides to
try another way. |
Ever persistent
and hopeful he thinks this approach is more likely to succeed. |

Here goes.
Hup and stretch!
The squirrel has claws which allow it to climb trees, plastic pipes and
even rough brickwork but the varnished, tin plated, steel doesn't allow
any purchase. What adds to the problem is that the tin is not a rigid platform
and tilts with the slightest pressure. |
Having to
admit failure the squirrel releases the tin and clings to the pole, unable
to do anything except slide down, clinging desperately with his face pressed
close to the pole. |

And so the
episode is closed with the tail touching the ground before he will jump
off. |
Now that's a truly down-to-earth Mission Impossible
Oh and by the way, the squirrels do get plenty to eat
from the ground; the birds have terrible table manners.
