I guess I didn't make it clear how big these grain bunkers are. They can be
500m long by 100m wide and 20m high. from my own observation it would appear
they are attracted to green tarps and less so to blue or white. Once the
grain is gassed or poisoned they need to be sealed, ofcause parrot chewing
holes spoils the grain and the process besides letting in water. For them
its usually a slow death for the grain company big losses..

The two suggestions so far is hessian screens, which I think would be
impractical and making the tarps unattractive by taste would appear to be
the most logical, but what could be sprayed on the tarps that would last for
a period and convince the parrots to go elsewhere. Most parrot (even Galahs)
are reasonable intelligent and one could reason that once the food source
was not available they would move on.

This problem is applicable to most grain producing states, one can only
guess at the mortality but it must be in thousands.

Any further suggestions accepted.
