Just a week after its birth on August 15, Byculla zoo's latest member, a Humboldt penguin nestling, passed away on August 22. The Brihanmumbai Municipal Corporation (BMC), which released this information only on Friday, said the chick died of congenital defects.

The penguin chick was born on August 15 to three-year-old Molt and his partner 4.5-year-old Flipper after an incubation period of 40 days. On the day it was born, the chick weighed 75 grams. The veterinarians at the zoo had then claimed that the condition of the chick was stable and they were recording its weight once a day. The zoo officials hadn't named the chick as they were unable to identify its gender. They'd planned to find it out through a DNA test in a couple of weeks.
