ALMOST a month after the mysterious tiger deaths at the Nandankanan zoo, the verdict finally seems to have been reached on what might have caused them. And the culprits are not the vets at Bhubaneshwar's Nandankanan zoo, nor the Berenil they panic-strickenly injected into the 16 tigers. The blame, if the zoo probe committee is to believed, lies with last year's cyclone, which brought down the zoo's enclosing wall and brought in the cattle from neighbouring villages.
