This also reminds me of Harpies who are often mixed up with sirens since they are both bird woman. Usually a harpy has more bird like features.


From the internet: Harpies are specifically wind spirits, and sirens, despite their avian appearance, are sea spirits.

From the internet: Sirens have the torso of a human, feathered wings and bird legs, it doesn't always specify head of woman or bird and in the odyssey it depicts the sirens as harpies so whatever design you think fits each better is up to you.
