Vampire Crow

Mimicry. The vampire crow can mimic simple sounds it has heard, such as a person whispering, a baby crying, or an animal chittering. A creature that hears the sounds can tell they are imitations with a successful DC 10 Wisdom (Insight) check.

Beak. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 1d4 piercing damage. Plus 1 necrotic damage that the vampire crow regains in health

Charm. The vampire crow targets one humanoid it can see within 30 ft. of it. If the target can see the vampire crow, the target must succeed on a DC 11 Wisdom saving throw against this magic or be charmed by the creature. The charmed target regards the vampire crow as a trusted friend to be heeded and protected. Although the target isn't under the vampire crow's control, it takes the vampire crow's requests or actions in the most favourable way it can, and it is a willing target for the vampire crow's beak attack. Each time the vampire crow or the vampire crow's companions do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 1 hour or until the vampire crow is destroyed, is on a different plane of existence than the target, or takes a bonus action to end the effect.
