Sparrow both species (house and Tree) appear to
have declined in the last 10 years in the Parkes region, to the point that I
regard Tree Sparrows extinct in the area. I can't put my finger as to why as
there hasn't been any increase in predators, such as Collared Sparrowhawks
or Pied Currawongs and we haven't got any Indian Mynas at Parkes yet. So it is a
bit of a mystery. In my own backyard I was blaming the Blue-face Honeyeaters,
who appear to have a hate on anything with feathers and keep the yard pretty
will clear of other species.
Another introduced species that has disappeared
from the Parkes region in the same time slot is the Goldfinch though this
species is still to found around Orange. Of cause there is a large number of
native species that have declined in the Parkes region over the same period
and must be of concern.
