Getting an UID is no longer just a unique human right. Tigers can have it too. The National Tiger Conservation Authority (NTCA) issued a guideline on Monday, proposing to assign a unique identification (UID) number to each tiger captured through camera traps. The NTCA wants to create a national repository of camera-trap photographs of tigers, and the UIDs will help cut out duplication and give the big cats an exact headcount. Tigers in the Sunderbans, for instance, will have the prefix ‘Su’ before a number while those in the Northeast hills will have ‘NE’. Tigers are identified on the basis of stripe patterns obtained through the camera trap images. The Ranthambore tigers are likely to be the first to get UIDs, officials said.
