This was for last week's Illustration Friday topic, "duet."
One of the first things I thought of when I saw the topic was symbiotic animal relationships, like those little birds who pick the little bits of meat out of crocodile's teeth... Then I remembered the Honeyguide Bird, and the Honey Badger. The bird is really good at finding beehives, but not capable of cracking them open. The badger is strong enough to break open hives, but not good at finding them. So they work together, making up for each other's weaknesses and reaping the rewards. A beautiful "duet."
