Siren or siren song.
The Sirens were nymphs (encountered by Odysseus) often depicted with bird-like bodies, who sang such enticing songs that seafarers were lured to their death. A siren has come to mean a seductive woman. It can also denote a device which uses compressed steam or air to produce a high, piercing sound as a warning. A siren song refers to something bewitching or alluring that also may be treacherous.
