Songbirds migrate at night,
sea birds by day.
Night birds navigate by the stars,
day birds, at least partly, by the sun,
the pre-fractal line of the shore,
The tern, arctic terns, sea swallows
fly from the Arctic to the Antarctic,
and return again in summer.
They fly both hemispheres,
the Old World and the New,
There’s a longitudinal division,
they fly up and down, not
round and round. Do they meet
on snow-covered ice? Are they tempted
by other landscapes, different shores?
