I think a lot of creatures are like this. I also think it's not just about territory. Many creatures, despite all the various descriptions we've given them, are tribal. Humans are, again despite the sociological wish that integration worked.
Same breed, different tribes. For me it gets more interesting when one tries to work out what makes an individual belong to this tribe or that tribe when the obvious is not visable. This is where knowing the history of an individual helps.
It's an unfortunate current view that states we are all the same and then seperates out the differences under the umbrella of culture. Perhaps if we accepted the differences within a species and managed socities accordingly we would have less problems when trying to manage them.
I'll be getting ready soon this morning to teach an online music class.
