The correct answer will be- flock defense
Explanation:
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.

Covalent bonds are the types of Bond which is formed by sharing of an electron between two atoms of same element or two different elements. The bond which is formed by the completely lost or gained of an atom is known as ionic bond.
