They dip their wings in the sunset,

They dash against the air

As if to break themselves upon its stillness:

In every movement, too swift to count,

Is a revelry of indecision,

A furtive delight in trees they do not desire

And in grasses that shall not know their weight.

They hover and lean toward the meadow

With little edged cries;

And then,

As if frightened at the earth’s nearness,

They seek the high austerity of evening sky

And swirl into its depth.
