Boundaries

We've been hearing Hooded Orioles (Icterus cucullatus) around our yard recently.  I was curious about why they were being so vocal, so I looked around a bit.  

I followed some loud chattering to an adult male:

 

Then I followed his line-of-sight, and some slightly fainter chattering, to a pair of orioles in the distance:

 

This is an immature male Hooded Oriole (on the left; note the black throat) and a female (on the right).  Perhaps the adult male and this pair were "discussing" the boundaries of their territories?
