P.A. Gilbert in an article in Emu [1] describes a survey (by rail) in
Autumn 1930 of Magpie-lark flocks around Sydney. The biggest was 3000
roosting in Moreton Bay fig trees in Centennial Park. He describes the
"grand spectacle" of this flock's arrival to roost. He notes these
flocks as forming in March and dispersing in July.
I don't think flocks of anything like this size occur now in Sydney.
Why they no longer occur is an interesting question, as is whether such
flocks occurred before European settlement of Sydney.
