Of the current in-game animals, I would mostly want to see chorus behaviour added to the dingoes, lions, prairie dogs (their jump-yip calls are contagious like human yawning, are used to determine how alert their neighbours are and I have certainly seen whole groups doing it in zoos) and American alligators.

As for animals that could be added that show chorus behaviour, the howler monkeys are probably the most obvious choices. I would also add the Southern ground hornbill to that list - groups will stay in touch by making a booming call that can be heard 3km away.
