classic waka stream

From mountain depths,
the cuckoos come and cry,
one after another—
as though asking aloud,
who among them surpasses all.

Meaning
The cuckoos coming from the mountains keep crying, as though calling out, ‘who among us is the best?’
Commentary
Book III, Summer Poems

The cuckoos are depicted as crying one after another, as if competing with one another.

If the particle “ka” in “tare ka masaru” is taken rhetorically, it can imply that none surpasses oneself.
