Two short scenes of nature, set side by side, with a date between them. The first is a quiet, overcast night or early morning: the air smells of coming rain, two screech owls call back and forth, and a grouse makes its low, thumping sound. The speaker seems to be listening closely, and the section ends on "an enormous silence," as if all those small noises only make the quiet feel bigger.
The second part changes the tone. Claws scrabble on bark, and a squirrel chase is called "furious." Then the chaser stops to lick its genitals, which is funny and a little blunt. The speaker doesn't dress it up or comment on it.
Together, the two parts create a mood of patient, unforced attention. The speaker seems content to notice, whether the moment is hushed and atmospheric or plainly comic. Nature here isn't grand or symbolic, just observed, and that honesty is part of the pleasure.
