Final answer:
When a person enters the flight zone of an animal, the animal moves away to maintain a safe distance. The flight zone represents the animal's comfortable space, and the invasion of this zone triggers a flight response.
Step-by-step explanation:
When a person enters the flight zone of an animal, the animal turns and moves away. The flight zone is the distance that an animal is comfortable with between itself and a potential threat or predator. Once a person enters this zone, the animal perceives it as an invasion of its personal space and a possible threat, triggering a flight response for the sake of safety.
In the context of birds, such as in the reference stating 'Birds physically touch other birds using tactile signals when they observe a predator entering their location', it suggests birds communicate danger within their social groups when a person enters their proximity or flight zone, leading them to move or fly away.
Similarly, wildlife such as wildebeests, when confronted with a threat, will migrate or move to maintain a safe distance. Predators, like the lions described in the example, exploit the flight zones of their prey, edging closer and coercing them into movement or panic.
