Each eve they embark
Whether in masse, or alone
To sojourn through the skies
In twilight's dusk they appear
Darting and whirling about
As though acrobats of fantastic feats
They chase their quarry
As if deranged, through darkness
Intent on making it the last
With tiny clicks they zoom in
On nimble winglets silent
Amidst vastness, a sonic reward
And each night as a wonder
They return to their drab, dry home
To sleep in shared warmth within
