A tune with no sound;
a bird sings in the morning.

So too-

Our hopes seem quiet;
as they are sung by our faith
  In hopes The Lord hears its calling.

On the wings-

Resting upon the High Almighty;
who hears of Silence's echo
  Feathers lost in the wind;
  relied on Him highly, as if to be soaring.

The God Bird is man praying to be heard.
