Re: Little Corellas; The Mallee moves to Mornington

    Michael Norris,
    I know of no direct evidence which suggests that the occurrence of
Crested Pigeons around Melbourne was the result of the release of captive
birds. I always believed it was part of a normal range expansion. I realise
that the apparent pattern of expansion is not that of a uniform spread as
they appear to have leap-frogged some areas. For instance, Graham Pizzey
tells me they haven't yet reached Dunkeld in western Victoria. This may have
something to do with habitat preference. Around Melbourne they have a
predilection for golf courses.
