In broad daylight, the bird goes quiet
It isn't fear
It answers to light, not to the clock
An internal clock tunes its song to the brightness
The Sun vanishes, the eye believes night has fallen
Silence

But it takes almost everything: the song only cuts out past ninety-nine percent of the Sun hidden
The hour never changed
Their clock just blinked
