Meaning of 鳴き声 in Japanese

A creepy cry that sounds like a human voice, velvet black wings, the image of tearing into dead flesh; crows are known across the world as an ill-omened bird that flies down with ill-luck.

A bird is known by its song and a man by his way of talking.

Above the music, I could hear her crying.

I used to listen to the calls of the wild birds in this forest.

Not a single sparrow was to be heard.
