Responding to a public interest litigation in the Bombay high court that seeks the deportation of the seven Humboldt penguins in Byculla zoo, the BMC and zoo authorities yesterday said they are taking utmost care of the birds, procured from South Korea last year. They also claimed that Byculla zoo is one of the best zoos in the country to keep the Humboldt penguins.
