"Philopatry is defined as the tendency of individuals to exhibit long term fidelity in the use of a particular area. Two major theories have been proposed to explain its adaptive significance: 1) the genetic theory, where individuals benefit from limited gene flow by the maintenance of successful alleles and allele combinations within the population, and 2) the environment familiarity theory, where individuals benefit from knowledge of local physical and social conditions. Geese pair in winter and early spring so the relevant units for studying the genetic implications of philopatry are the wintering and the spring staging populations"--Abstract.
