In 1950 White Ibis were rarely seen in West Aust south of the
Kimberley but during the 1950's they started spreading south and now
have rookeries well south of Perth. As a young bird watcher we never
saw them in the SW of WA and even Straw-necked Ibis were not common
in the SW except just South of Pinjarra.
Look out Melbourne - White Ibis are starting to inhabit Melbourne's
parks. One has just recently taken up the Wurundjeri Walk as a daily
home and must be competing with the two White-faced Herons who have
just managed to make a living out of this small park over the last 20
years.
We have changed the face of Australia so much and global warming
appears to be pushing birds further south as well that we can expect
some changes - does not mean we have to accept them all - I guess.
Happy birding

The ibis situation is certainly a complicated one.
