Ranchi: The Bhagwan Birsa Biological Park in Ranchi reopened for visitors on Friday after 85 days and on the first day, 350 visitors set foot on the 156-acre zoo to get a glimpse of the resident animals. Zoo director Y K Das welcomed the first batch of visitors with bouquets. For many, the newly introduced double riding bicycles were an added attraction. “The visitors have been mandated to wear masks and use hand sanitizers at all times. Social distancing has to be maintained as well,” Das told TOI. Even though the state government has allowed the assembly of 50 people at a given time in a public place, the park management mandated that not more than 25 people will be allowed in at once.
