I tend to see this as a secondary reversion in the rattites, one
that goes along with the loss of flight. (After all, without flight,
how do they *get* to the out of the way places!!)
Also, I didn't mean just, or even primarily, trees. Islands are
as isolated, so are cliffs. Redwing blackbirds nest in dense stands
of rushes or cattails, always well out from shore, and *over* water
(no land underneath at all).
The peace of God be with you.
