The English language has some wonderfully anthropomorphic collective nouns for groups of animals!
There is a Pride of lions;
a Murder of crows (as well as their cousins the rooks and ravens);
a School of fish; an Exaltation of larks and a Parliament of owls.
Now consider the baboon: loudest, most dangerous and viciously aggressive of all primates.
It is ironic and so appropriate that the proper collective noun for a group of baboons is: a Congress. Very fitting for the real "Congress of Baboons"!
