While I was waiting for the talk to begin, I spent a few minutes sketching Bull, the white rhino that stands at the entrance to the BioDiversity exhibit on the 2nd floor.
Here's how my sketch turned out:

One of the interesting things I learned today was that while white rhinos were previously an endangered species, they have been protected for the past hundred years or so and their numbers improved to such an extent that they were taken off the endangered list. Unfortunately, they are now at risk again, as poachers are killing them for their horns, which are believed by some to be an aphrodisiac. In reality, their horns are made of keratin, the same material that our fingernails and hair are made of, which has no such magical power.
