Dragonflies, Bats, and Hummingbirds

Constitute the sole fauna
Of my desert balcony,
Engraving the empty air,
Wings with no shared ancestry.

All are small. All are hungry.
All are marvelous,
Aerodynamic,

Fine machineries.
They rise into sight,
Just before and after night,

Against a thin atmosphere.
Fish had it easy, but these,
Whose ancestors found a way
To rise, have conquered surprise.
