I have read about the drop
in insect numbers as well (WRT sparrow numbers), but it seems since everyone
stopped using flysray there are loads more spiders in my garden and about the
place (presumably capitalising on increased insect numbers) than ever
before.
As far as predators, I
don't know about collared sparrowhawks in Canberra, how often are they
seen in Sydney?

PS: Thanks for all the
penguin info
G'day all,
A year or so the number of sparrows in my territory
seriously declined but
about 6 months ago the numbers returned to the more
recent normal
They arrived here 1966
