A report by Wildlife Trust of India today said, from unprotected exotic birds to birds under Schedule I of the Wildlife (Protection) Act, 1972, all are being sold in the fair.
The report claimed an enforcement assistance team of WTI which surveyed the fair also found nilgais, porcupines and several other species protected under the Wildlife (Protection) Act on display for sale.
The state government rejected the allegations and said the officials of forest department keep a watch in the fair to prevent such instances.
"We want to know if any organisation has detected trade in banned wildlife happening at the Sonepur fair, why doesn't it immediately file a case there itself. Who stops them?" Prasad added.
The report claimed animals were stuffed into small cages and displayed publicly at the month-long animal market, which began on November 5 and will continue till December 4. Two species of primates - langurs and macaques were also being sold at the fair, it added.
