Paired Things

Who, who had only seen wings,
could extrapolate the
skinny sticks of things
birds use for land,
the backward way they bend,
the silly way they stand?
And who, only studying
birdtracks in the sand,
could think those little forks
had decamped on the wind?
So many paired things seem odd.
Who ever would have dreamed
the broad winged raven of despair
would quit the air and go
bandylegged upon the ground,
a common crow?
