On the OTHER hand, it requires you to either have a lot of plastic bottles, or to wash them afterwards.

On the subject of eggs...

The females of superb fairy-wren (Malurus cyaneus) start singing to their unhatched eggs in order to teach the embryo a “password,” a single unique note, which nestlings must later incorporate into their begging calls in order to get fed.

Since plastic drinks bottles are something that happen a lot to us (and mostly get chucked into the recycle bin), I'll try that out. I suspect it needs exactly the right bottle to work.

Fairy wrens - wow!

Be sure to report back.

And yes! It is wow! Birds can be so awesome.
