Swifts are hunting,
They glide and hover,
Recede and come again
Great clouds thunder
Above blue sky
They bank and bend
Their wings to warp
And straight again
Great clouds thunder
Above blue sky
Quick and light
Their spiral flight
They take their prey
The great clouds thunder
Above blue sky
Gray and deep,
Or luminous
The rose clouds keep
The great clouds thunder
Above blue sky
They glide and grow
Swell and show
Their height and depth
Above blue sky
The great clouds thunder
