Yes, we discuss this every 3 years. I’m not aware of any
research. A starting point would be to monitor a significant number of sites
and determine, for example, which species begins nesting first. A similar question
concerns black-and-white species nesting in the same tree.

Flycatchers
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
