A group of international marine scientists tagged almost a thousand bluefin tuna in order to study their migration patterns, and interesting results have recently been revealed. It appears that there are two genetically separate groups of tuna that share feeding grounds in the Northern Atlantic ocean. Amazingly, once spawning season rolls around, the fish separate out into their individual groups and head straight for their respective places of birth to mate! "There has to be some kind of genetic component because
the fish may be in the western Atlantic for three or four years,
hanging out in feeding areas, but when it is time to spawn they make a
bee-line straight through the Straits of Gibraltar to their spawning
grounds in the Mediterranean,"said Dr. Andre Boustany, from the Tuna Research and Conservation Center at Stanford University, California. "This would not happen unless the fish were natally homing and the two stocks were not interbreeding at all," he says. This behavior has been hypothesized, but never proven - until now.

And speaking of homeward migration...here is a review of a sociological study on the concept of home. It appears that one's integration into the culture and society of your area is the prime determinant of attachment to that particular locale. In addition, the longer you stay the more attached you become. I know that appears logical, but the study is an interesting read.
