Well, isn't that just a lovely little mystery we have here? Let's paint a picture with numbers. If we add up the birds they saw each day, we get 15 + 12 + 13 + 19 + 20 = 79 birds in total. And since they saw the most birds on Friday, they must have seen 20 birds on that day. Such a happy little bird-watching adventure!
