Hi David

I see you really want to know about food for Little Lorikeets.

Sugar Gums E. cladocalyx seem to be their favourite trees by far in Bayside.

I say "seem" because I don't know trees very well so often the species goes

I wonder if it is to do with their size (to 35m).  The Litttle Lorikeets are
often very high in the canopy and this seems to make it easier for them to
evade the bullying by larger birds. Another large tree, Mahogany Gum, also
appears quite often on the database.   (And also the dwarf form of the Sugar
Gum - nana - but only near to the full size form).

Of course there would be fewer bullies around if there were fewer exotic
gums and I wonder if "we" have done Little Lorikeets a disservice by
planting them.  Littles were "plentiful" here before the "plant native"
movement had a real impact (1967).

Re that I see that in Tim Dolby's list (thanks for that!) there is only one
tree indigenous to my area (Blackwood, Acaca melanoxylon).

Some research at Deakin Uni showed that bird diversity is related to
indigenous tree presence....
