The last 10 days must have been a tiring experience for the Humboldt penguins at Byculla Zoo, with more than 2.5 lakh people visiting the place to catch a glimpse of them. On Tuesday alone, over 20,000 people thronged the zoo on Gudi Padwa. However, learning from past experience, this time the zoo administration had made better security arrangements for managing the crowd.
