While everyone was counting down to midnight last week, London Zoo staff were gearing up for another kind of count -- the yearly "stocktake" of each and every animal on the premises. As we will see, it's been a busy week knocking on doors and hoping the animals won't avoid the census takers. Luckily, it's the age of the Internet and social media, so we get to see them at their work. Here the zoo's multiple penguins mill about and do their best NOT to be still so the counter can get an accurate tally.
