Hi Tim and
others,
It occurs so
often that it would not be coincidence. As both are migrants who arrive here at
a similar time, but importantly the Noisy Friarbirds is more common than the
Leaden Flycatchers, then there need not be any benefit for the Friarbird, for
the situation to develop. If there is enough nesting Friarbirds to meet
the requests from the Flycatchers and the Flycatchers can find them
easy enough, then any benefit can be one sided. Protection and defence seems a
good candidate for a likely benefit but that is just me supporting your guess.
Although quite possibly the Flycatchers might provide some benefit by being
extra eyes alert to possible danger.

obvious thought it is that
some kind of protection for flycatcher but what would friar bird get out of this
? Or maybe just coincidence - both have similar nesting requirements - anyhow
just guessing
