Answer 1

Drongo
Fork-tailed or common drongos have been observed using alarm calls to cause animals to abandon food, which they eat, getting up to 23% of their food this way. They have a range of alarm calls which they appear to vary until they find one which works. Drongos range from Africa to Central Asia, Australia, and western Pacific islands, inhabiting forests, open country, and gardens.
