During nesting season, a breeding bald eagle pair tends to return to the same territory year after year, re-staking their claim on an existing nest and the area surrounding it. They often position themselves at the edge of their territory, perched on tall branches, on the lookout for possible intruders. Their presence alone is a signal to others to stay out.
Both the male and female defend their nest and territory against predators, especially ravens and other raptors. If a neighboring eagle flies too close, the resident adults will chase away the intruder with shrill high-pitched cries. The male eagle usually chases off other males, and the female chases off other females. In extreme cases, they will engage in aerial tumbles and talon-locking battles with a persistent predator.
