Discovering London

Among the people I met at last night's London Historian drinks was Peter, author of Discovering London. This great blog is full of fascinating information about the city, not to mention a prize quiz on London's elephants. It made me realise how many of the animals are wandering the city streets: I recognise a few, but by no means all 21!
Londonist has already highlighted the huge pride of lions in London. What other animals feature heavily in this architectural menagerie? (The City of London dragon pictured here doesn't count, being mythological...)
