Hi Michael,
Out here at a Carwoola the Red Box are flowering and our bee keeper is very 
happy with the honey flow.  Interestingly the Red Box trees  don’t all flower 
at the same time.  Some have finished and others nearby are still in bud.

The Dusky Woodswallows are nesting here communally in a big a Yellow Box.
