This is International Zookeepers' Week! My tie (from Zambia) has two elephants, a secretary bird, and a lion. When I was growing up, we took an annual trip to the Philadelphia Zoo, which at that time stored many of the animals in narrow walled enclosures and concrete-lined pits. Happily for the animals and their visitors, well managed zoos now provide carefully designed natural habitats for their animals, focusing strongly on the animals' welfare and security, and recognizing their needs for community and privacy.
