HYDERABAD: With rains for the last few days having delayed the original schedule, a team from Nehru Zoological Park will be leaving for Goa next week to bring a pair of bisons from the Bondla Zoo. The zoo here had initially planned to shift the pair in the first week itself for which purpose necessary permissions have already been received from the Central Zoo Authority (CZA). According to officials, the moats and cages which have been lying vacant after the last of the bison here died five years back have been cleaned and readied for the new occupants.
