The results of the Queensland Garden Bird Survey, (Sunbird 2002 32:37-51)
mainly centred in SEQld, show that House Sparrows are still present but
they have declined.
In 1979/80 they were recorded from 69% of sites, in 53% of weekly records
and with mean maximum numbers of 6.6.
A similar survey conducted in 1999/2000, showed that they were recorded from
37% of sites, 18% of weekly records and mean maximum numbers of 1.0.
So there has been a marked decline but it is not confined to the House Sparrow,
10 species declined by at least 10% over this period - these were small
species,
and 19 species increased by at least 10% and these were large species.
