There are no takers for the Mumbai penguins. The Veermata Jijabai Bhonsle Botanical Garden and Zoo approached several zoos of the country for an exchange arrangement. Meanwhile, the zoo authority will invite about Rs 300 crore tender for the expansion of the zoo on the seven acres plot.

“We have already forwarded proposals to the Sakkarbaug Zoo and Jamnagar Zoo to exchange their animals with our penguins. But we did not receive any feedback from them,” said Dr Sanjay Tripathi, director of the Byculla Zoo. Introducing any new animal in the zoo is a lengthy process. They need to take permission from the central government, an official added further.
