Similar story to the article I wrote years ago about the Rainbow Lorikeet.
• (1991) ‘The changing status of the Rainbow Lorikeet Trichoglossus
haematodus in South-east Australia: the role of wild and escaped birds’,
Australian Bird Watcher 14: 3–9. (Investigates the range increase.)
Particularly about that the species did not occur in Melbourne in the 1970 and
is now abundant and this article explores the early showings of this change.

Subject: Musk Lorikeets in Sydney and species diversity
Hi Chris, the increase in Muskie numbers is interesting.
In much of northern Sydney they were a rarity in my experience, and then in the
late summer and autumn of 1995 they appeared throughout much of the area. Since
then they have been seen annually at that time of year. We moved to Roseville -
Lindfield in Jan 2001 and Muskies have been visitors to the garden every Autumn
since. They appear to be following the flowering eucs.. Then during the summer
of 2014 -2015 (from memory) they appeared for much of the summer, for the first
time, and stayed on through autumn. Last year they weren’t noticeably present
in Summer. This year for the second time during summer we had the first first
local records at the end of Spring or early December. Whilst I haven’t birded
widely in northern Sydney recently I can confirm that I have seen Muskies at
home in the Lance Cove catchment on the borders of Roseville and Lindfield,
Sydney Olympic Park, Macquarie Uni, and last weekend quite good numbers at
Barton Park in North Parramatta.
I suspect that recently there has been an increase in euc canopy cover in
northern Sydney and this has provided a food resource for this species and also
partly accounts for the annual sightings of Pacific Bazas these days. Bazas
have been annual visitors to our garden for a good number of years and almost
certainly nest locally. A big change from the 1970s when they were virtually
unknown in Sydney.
