It'll be interesting to see if this is just an irruption as
it has been called, or whether it's just part of the general
spread and urbanisation of this species. Ten years ago it
was almost unheard of to have YTBCs in the suburbs of Geelong
in Victoria - now it's not unusual to see small flocks
throughout the town, and considerably larger flocks in some
places such as the parkland surrounding the Geelong Botanic
Gardens. Crops of Pinus radiata seed seem to be the key once
the birds have discovered their presence. If the birds
flying around Adelaide at the moment discover groves of
mature Pinus radiata, I wouldn't be at all surprised if they
then become regular visitors.
