through the gaps in trees
the mountain hototogisu
I can hear come forth singing.
Meaning
From among the trees where the dawn moon has just set, I hear the mountain hototogisu come forth, singing.
Commentary
Summer Poems 151

Headnote continued from the preceding poem: "The hototogisu"
The poet hears the mountain hototogisu emerge, singing, from among the trees where the dawn moon has just set, as if taking its place. Overlaying the vanishing moon and the appearing bird in a single gap of trees, he captures the transition before daybreak.
In the source text consulted, a character in line 3 could not be read and has been supplied from the Teika text's ko no ma yori.

Line 1, ariake, is the moon still in the sky after dawn. Time has moved on from the "late-night moon" of the preceding poem to the moon before daybreak.
Line 2: nuru is the attributive of the perfective nu, showing that the moon has set. Whereas the preceding poem has the bird singing in moonlight, here the bird emerges after the moon has gone.
Line 3, "from among the trees," makes the place where the moon set and where the bird appears one and the same.
Line 4 is the mountain hototogisu continuing from the two preceding poems.
Line 5 is the same as the last line of 145, with nari inferring from sound.
