Step-by-step explanation:
The animals sent out The Great buzzard as a predator warning call to deceive other birds into fleeing from a food source that the animal making the call could access. Biologists have observed this behavior in some animal species, where individuals make predator warning calls even when no predator is present. This behavior is a means of communication and helps the animals gain access to food.
