Hi Peter and others
Thanks for your great posting. We have the same problem
here in South Africa with people's desires to emulate a sort of second rate
northern hemisphere home and have plenty of House Sparrows, Common Starlings,
Chaffinches (not too successful though and restricted to Cape Town), Common
Mynas and Indian House Crows to name but a few.
We have another problem too though - Australian trees!
Unlike the Aussies South Africans have a sick (for us at least) love affair with
eucalypts, Australian acacias (our are obviously not good enough) and casuarinas
which are used for all sorts of things from massive plantations in our
grasslands to windbreaks and avenues lining farm driveways. This has a
profound effect on our bird life. Here where I live in relatively pristine
grasslands an unpublished study has shown that we have around 190 species of
birds per square kilometre. In the quite nearby agricultural areas and
tree plantations this figure drops to around 110 and 70 respectively.
Studies in Kenya have shown a similar difference between indigenous forests and
encroaching eucalypt plantations. So don't despair - someone loves
Australian trees - just not Australians it seems :-(
