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.

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.

 

Philip

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
