Archibald Lampman - Snowbirds

Along the narrow sandy height
I watch them swiftly come and go,
Or round the leafless wood,
Like flurries of wind-driven snow,
Revolving in perpetual flight,
A changing multitude.

Nearer and nearer still they sway,
And, scattering in a circled sweep,
Rush down without a sound;
And now I see them peer and peep,
Across yon level bleak and gray,
Searching the frozen ground,-

Until a little wind upheaves,
And makes a sudden rustling there,
And then they drop their play,
Flash up into the sunless air,
And like a flight of silver leaves
Swirl round and sweep away.
