I am curious to know if the birds are really existing in plague proportions,
or whether their natural food source has been so depleted that they are
forced to congregate in urban areas to find food? I feel that the
`congregation' of birds can create an illusion of a plague, when the problem
may well be loss of habitat (and that actually sounds more plausible to me
Birds go where food is.and breed proportionally. I think a more humane and
effective approach to populaton control would be to control their food
supply. Maybe the Corella's in question have lost a lot of natural habitat?
