In a flock of birds one individual first gives a call when a predator appears. This call is quickly repeated by all members of t
he flock and soon the entire flock is calling at this predator. This activity seems to deter the predator. When this barrage of calls is given the predator always flies away. This is a possible example of ______
A flock is a group of same species of animals usually observed in the birds during migration.
The flock increases their fitness of survival by avoiding predators in which the one individual of the group gives a call in response to the predator.
The same predator call is repeated by every member of the flock which threatens the predator and the predator goes away. This flock response is considered as the defense response to predator and thus the mechanism is known as flock defense.
