Storm, if there's a general food shortage at the moment, that would also be 
affecting trees previously in cleared areas if they were still there, wouldn't 
it? Ie we'd have more flying foxes, but they'd still be starving?

Hi All

The flying-foxes moved to Lachlan Swamp, CPT following the dispersal in RBGS.

The camp in Kareela started after the desal plant was constructed on the same 
block as the camp as Kurnell. Animals are slowly starting to use the camp at 
Kurnell again but it's not clear they will ever leave Kareela completely, 
despite the ongoing (though presently suspended because of the food shortage) 
dispersal action.

There is a significant food shortage effecting the grey-headed flying-fox 
though the range from Melbourne to SEQ.  Where there is flowering, nectar flow 
is poor. This food shortage has seen numbers into care in excess of 5 x the 
normal numbers coming into care over the last 6 weeks. Animals are in parts of 
the range associated with food shortage (western NSW/ Victoria/ SA) Thousands 
of young have died. Hundreds of adults have died.

Bringing this back to topic, the lack of flowering / poor quality flowering may 
also be driving the movement of the musk loris this season.

Dr Peggy Eby discusses the food shortage in this article:

In the case of the flying foxes, it's a pity we don't know enough about their 
movements to pinpoint the lost habitat. People's anger at their presence could 
then be redirected to those involved in the clearing.

I don't think many people are annoyed by lorikeets like they are by flying 
foxes. Provided they aren't right by their house, they're welcomed, and even 
then many are prepared to put up with the noise.
