"To be fair, the laborious count is not just a bureaucrat's idea of a joke. Precise numbers are needed by the International Species Information System, which oversees zoo breeding programmes to help save endangered species. One species under threat is the Sumatran tiger, two of which are set to move to London Zoo when the new £3.6 million Tiger Territory enclosure opens this Spring." (from here)
Although I didn't visit the ZOO during my last trip to London, I will definitely go back to see it. After about a half hour into our trip, as we drifted along Regent Canal in a canal boat, we saw the spot where you can get dropped off and picked up. The birds were on one side of the canal, while other species were on the other. It seemed as though the canal was winding its way through a thick jungle forest, even though we knew were in the middle of one of the biggest cities in the world! I hope you enjoy this short slideshow of our boat ride along Regent Canal on the way to the London Zoo.
