To anyone knowledgable:

I have four independent questions.

1) Are there any well documented cases of hybridization occurring in
the wild in Australia in which the offspring of the cross have become
established as an independent race, subspecies, etc.?  Or, do any two
races commonly hybrize, but their offspring fail to reproduce themselves?

2) Does anyone know why Eastern Yellow Robins cling to the side of small
trees, bushes, etc as oppose to perching "upright" on a branch while
foraging?  Any thoughts on this would be welcomed.

3) In terms of the number of people who have seen fairy-wrens which
species is the most commonly seen across Australia?  I would guess that
the Superb Fairy-wren is because it resides in the more populated regions
of the country.

4) Granted that fairy-wrens look different from each other, but do they
also have commonly known differences in behaviour across species or do all
species act pretty much the same?  There is much written about the Superb
fairy-wren, but I have failed to find information on the behaviour of the
other species.

Cheers, Jim
