Ring necked parakeets

Back in November David Chapman wrote an article about ring neck parakeets in which he praises their being around but admits they do compete with our native species, a fact he glosses over as if it does not matter.  I've just read an article in another magazine that features parakeets and how they affect our native birds by keeping them off bird tables, taking nesting sites from other species that use holes in trees like wood peckers. They also cause major damage to fruit farmers crops and as such are on a very limited list of birds that can shot for so doing. The article I read refers to them as the grey squirrels of the skies. If we are to act as conservationists then lets conserve our native species not invaders. Please do not encourage parakeets in any way.
