hierarchy, social interactions between members

Research about animals that we need to observe at an online zoo
Please use online zoo cameras to visit the zoo, (San Diego has them), and observe the primates.
Choose two or three species to observe and document their behavior.
Things to consider are hierarchy, social interactions between members more generally.
For species that are sexually dimorphic, you can look at behavior differences between the sexes as well.
Also, how do they interact with their environment, is there a coveted spot that they compete for or one member guards? Do they appear to play with items in their enclosure or use items as tools?
You will then compare the behavior of the primates with that of modern humans.
