Sparrows used to be about the most common bird in this part of
London. Then all but disappeared perhaps 10 years ago. And although
they've returned, in nowhere near the same numbers.

What happened to cause a reduction in their numbers?

I dunno. I've searched, but found no definitive answer. They seemed to
disappear near overnight.

I've hear mention of this a number of times. In general with people also
saying they don't know the cause.

I heard that it was the unexpected result of an ill-judged campaign by the
RSPB to preserve the sparrowhawk, but I have no idea if there is any truth
in this.
