BRISTOL, ENGLAND - JANUARY 07: Rachel Moore counts the penguins during the annual New Year animal stock take at Bristol Zoo Gardens on January 7, 2009 in Bristol, England. The mammoth task involves a complete head count of every animal in the Zoo which includes more than 450 different species, from tiny leaf insects, hundreds of fish, dozens of penguins, masses of monkeys and Jock, the 150kg male lowland gorilla, who lives on Gorilla Island. Added to this year's list will be the Zoo's 2008 new arrivals which included a orphan gorilla, a tiny turtle, a baby lemur, an armadillo, hundreds of tropical butterflies and the smallest deer in the world.
