Tim,
With regard to the Moreton Bay Fig trees, they have been a prominent tree in
Victoria for 150 or more years. Most of the stately homes (Como & Ripponlea) &
Bot Gardens have many very large old figs.
Regarding the pincer movement mentioned by Laurie, the records for Rotamah
Island BO would show movement of Koels on the coastal route.
Cheers
Ivor
