Black Tern -- Chlidonias niger, at Wisconsin's Horicon Marsh, and "Seeing for a Moment":
'I thought I was growing wings—
it was a cocoon.
I thought, now is the time to step
into the fire—
it was deep water.
Eschatology is a word I learned
as a child: the study of Last Things;
facing my mirror—no longer young,
the news—always of death,
the dogs—rising from sleep and clamoring
and howling, howling,
I see for a moment
that’s not it: it is
the First Things.
Word after word
floats through glass.
Towards me.' ~ "Seeing for a Moment" by Denise Levertov, from "Oblique Prayers", 1981.
