 As seals are distributed over such a large area, these display behaviours can slightly change geographically as males try to appeal to the largest number of females possible over a large geographical range.Dive displays, head flicks, and various vocalizations all work together in a display behaviour that signifies to the females in a colony that the males are ready to mate.Display behaviour is a set of very conspicuous behaviours that allows for the attraction of mates but also can result in the attraction of predators.
