Philopatry

Broadly, philopatry is the behaviour of remaining in, or returning to, an individual's birthplace. More specifically, in ecology philopatry is the behaviour of elder offspring sharing the parental burden in the upbringing of their siblings, a classic example of kin selection. It derives from the Greek 'home-loving', although it can be applied to more than just the area that an animal was born in. Philopatry can manifest itself in several ways.
