Snake Demands Its Eggs Fresh

Species of South African Snake With a Dainty Appetite and Keen Sense of Smell

The South African snake called the eggeater has inherited from long generations of ancestors a sense of smell so acute that it appears never to be at fault. Professor Fitzsimons, director of the Port Elizabeth museum, gives in his book on "The Snakes of South Africa" an interesting instance of the wisdom of these serpents.

"Being short of fresh pigeons' eggs once, I went to my cabinet and took the clean-blown shells of a few doves' eggs. Beating up the contents of a fowl's fresh egg, I syringed them into the empty shells, and carefully pasted tiny bits of tissue paper over the holes. I put these in the eggeaters' cage, and watched, for I expected the snakes to swallow them as they did the other eggs. First one eggeater advanced. He touched each egg gently in turn with the tip of his nose or the point of his forked tongue, and crawled away in disgust. Another and yet another eagerly advanced, repeated the performance, and straightway retired. I began to get interested. Leaving the eggs, I returned in a few hours' time to find them still there.

"For two whole weeks those eggs remained in the cage untouched, although I refrained from giving the snakes any others. Then I procured some fresh pigeons' eggs and put them into the cage. The snakes approached, touched them with their noses or tongues, and instantly began to swallow them. I tried this experiment a second time with the same result. Frequently I have noticed that the snakes would eat some of the eggs that I gave them, and reject others. On breaking the latter open, I always found that they were either addled or else had a partially developed young bird inside. I could never induce an eggeater to swallow an egg that was not perfectly fresh.

"The eggeater is an expert climber, and his sense of smell is so sharp that he can discover birds' nests with the greatest facility. If you place an empty bird's nest in the cage of an eggeater, he will take no notice of it, except to use it occasionally for a cozy bed. But if you put fresh eggs in it, he at once detects their presence, although they are hidden from his sight." — Youth's Companion.
