"No -- seals do"

Calista's tumblr is really quite marvelous, consider, for instance, this new post, quoted in full:

W. H. Auden (from “Shorts”)

  Many creatures make nice noises,
  but none, it seems,
  are moved by music.

in the margin, E. Bishop:

   no — seals are

[ed.] The context here is Bishop singing to the seal in "At the Fishhouses":

Cold dark deep and absolutely clear,

element bearable to no mortal,

to fish and to seals . . . One seal particularly

I have seen here evening after evening.

He was curious about me. He was interested in music;

like me a believer in total immersion,

so I used to sing him Baptist hymns.

I also sang “A Mighty Fortress Is Our God.”

He stood up in the water and regarded me

steadily, moving his head a little.

Then he would disappear, then suddenly emerge

almost in the same spot, with a sort of shrug

as if it were against his better judgment.
