In Greek and Roman myth Sirens were bird-women. There were fish-tailed sea deities and nymphs, but those weren't called Sirens.

In British, Nordic and German folklore fish-tailed Mermaids and bird-like Sirens remained separate beings, but in Italy, Spain and Portugal the Mermaid and the Siren were folded into a single fish-tailed creature.

KC is obviously taking inspiration from the Anglo version of the myth.
