If that was in the 80s, I wonder if it still happens.  Surely there are far 
more native trees for them to feed on now.

Subject: What would cause thiamine deficiency syndrome in     birds?
This has been recorded in the Red Wattlebird in Australia (see abstract
below). I remember talking to David Paton back in the 1980s about this
research and he thought that, in winter, Red Wattlebirds were feeding on the
nectar and fruits of exotic plants in parklands and gardens of Melbourne, in
preference to the their natural diet. His conclusion was that these exotic
plants were deficient in thiamine, compared with levels in their natural
diet.==============================www.birding-aus.org
