Multiattack. The harpy makes two attacks: one with its claws and one with its tail.

Claws. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 6 (2d4 + 1) slashing damage.

Tail Whip - Melee Attack: The harpy uses its now featherless tail to attack. Make a d20+3 attack roll with 5ft reach. Tail does 1d6+2 bludgeoning damage, and 1d4 necrotic damage.

Instill Fear - The harpy screeches frighteningly to nearby creatures. Every creature within 15 ft must succeed on a DC 12 Wisdom saving throw, or movement be reduced to zero until the end of the Harpy's next turn.

Luring Song. The harpy sings a magical melody. Every humanoid and giant within 300 feet of the harpy that can hear the song must succeed on a DC 11 Wisdom saving throw or be frightened until the song ends. The harpy must take a bonus action on its subsequent turns to continue singing. It can stop singing at any time. The song ends if the harpy is incapacitated.

While frightened, affected creatures have disadvantage on Ability Checks and Attack rolls while in Line of Sight. The creature cannot willingly move closer to the source of its fear.

A target that successfully saves is immune to this harpy's song for the next 24 hours.

Continue Singing - Harpy must take this bonus action to keep the frightened condition active after beginning the Luring Song.

Consume Flesh - The Harpy may consume flesh nearby (living or dead) to regain 1d6 hit points.
