It turns out it's not so straightforward to define a vocalisation, when you whistle or tongue click you are not vocalizing (in my opinion).

Is there tight coevolution between avian vocal signals and hearing-or do signallers and perceivers evolve more loosely?

It turns out perfect tuning is not required...
