G'day Dick ,
I think you are completely on the right track by changing your planting
that is drop the grevilleas , Bio-diversity is the answer , as the largest
proportion of birds depend mainly on insects for their diet , it is the
insects you need to attract .
I started on this place 15 years ago with less trees than you have to start
with and the same acreage , I have excellent growing conditions which makes
life easier , but I'm intending to have the whole place planted out , (
only a few acres to go now !).
I don't consider Noisy Minors a problem at all , I started with a few
taking control of the place , slowly building up in numbers to what was
starting to resemble a plague , they totally harrassed EVERY other species
who dared even fly over ,let alone attempt land . As the planted areas
started to grow , species who could stand up to the Minors nonsense started
to settle in . I have recorded 136 species here now , 80% of those are
permanent residents , and 70% of those ,I have recorded as successfully
nesting . The Minors are here but in balanced numbers , they still chase ,
harrass , and bully any bird they think is fair game , but even seem to get
bored with that fairly quickly . I think a large proportion of the other
species rely on them for warnings of snakes , cats , hawks , etc , so they
have a plus side.
I have not had experience with them harrassing Indian Mynahs , but if this
is the case , then it is certainly another big plus , there is no question
as to which species is a true PEST .
This is not the correct forum for me to rabbit on about what to plant
,except to say create as many different habitats as you can , with each
containing the greatest diversity of plants you can get hold of , and
expect it all to take a LONG time to evolve .
I would be happy to chat more on this subject , if you want to E-Mail me
any-time Dick .
