Hi,
Noticing that it was raining (according to my Davis VP) when it
obviously was not, a quick check showed that bird cr*p had caused an
almost total blockage. It is obvious, now, that it is used as a perch
by a flock of house sparrows.

I did think to construct something akin to the 'spikes' used in cities
to deter pigeons perching, but wondered if anyone could suggest a
quicker fix.

A cat??? House sparrows have become quite rare so perhaps a non - lethal
deterrent might be a better idea. What about a stick - on hawk on the
house window??
