Ring Neck Parakeets

[Chipchopper]

Are they responsible for contributing to the decline of native hole nesting birds, like owls, woodpeckers, starlings, nuthatches etc.

[rowanwitch]

Woodpeckers are struggling where they are very common not sure about the others, however they are spreading so rapidly they are likely to displace a number of native species unless nature provides a control.... we need a few more peregrines.
