it's like the eye of a duck

***chuckles*** You've just made me realize that the two books reflect the pro/amateur thing as well. One is written by a scientist. The other is by a non-scientist who has been fascinated by the Tsavo lions most of his life, after seeing the Field Museum specimens when he was a boy; he wrote his book after finally achieving his dream trip to Tsavo in middle age and getting to hang out with the scientists who were there studying the lions. :-)
