A rare Rothschild’s giraffe, born last week, takes its first steps on Thursday. Narus is already over 6ft (1.8m) at only a week old, but remained under the watchful eyes of his parents Orla and Meru as he explored his enclosure at Chester Zoo. The Rothschild’s species are named after zoologist Lord Walter Rothschild, founder of the National History Museum in Tring, Hertfordshire but are critically endangered, numbering as few at 1,600 worldwide
