CHESTER, ENGLAND - JANUARY 2017: The elephant calf was the second to be born to the herd in a month in Chester, England, January 2017. AMAZING night cam footage has captured the birth of an Asian elephant at Chester Zoo. Following a 22 month gestation, and a short 20 minute labour, the male calf was born to two-year-old mum Sithami Hi Way. Zoo keepers stayed up to monitor the birth via live CCTV and watched in awe as the baby dropped onto soft sand and scrambled to his feet in minutes.
