"The calf was killed while its mother named Sada was injured in the tiger attack," DNP Deputy Director V K Singh told PTI.
The mutilated carcass of the calf was recovered today from Kakraha Tal when patrolling teams, he said, adding that pugmarks of a tiger were also detected there following which patrolling has been intensified with deployment of half a dozen elephants for the purpose.
Four rhinos have been killed so far in tiger attacks while two rhinos, Himrani and Deepa, have sustained injuries.
"It seems that rhinos have now become a part of Dudhwa tigers' menu chart, which should be studied," a DTR official said.
