The Phillip Glass bird

In our continuing series....

We've noticed a bird that has only one note - a whistle repeated every second without pause. This goes on and on and on. On waking up in the night, one can think that it's gone but then it's back again. The note does seem to change occasionally - perhaps every few hours - but only by the smallest amount. Hence the name - the Phillip Glass bird.

And we do so look forward to those pitch changes.
