Sufficit Caelum Magna ; . After 4 days at a lake resort in Lagos, Nigeria, I finally figured out why these birds fly in a large group at sunset while making beautiful noise(s). They do this to exchange information on feeding sites found during the day and they fly in circles at sunset to provide protection against predators and to keep warm before roosting when night falls. This caught my attention because it's everything I stand for; strength in numbers and sharing profitable information to help each other grow. I mean if birds can do it, why can't we?
