The Delhi zoo received two tigresses and a pair of sloth bears from Maharashtra on Monday morning under an animal exchange programme, officials said.

In return, the Delhi facility will provide sambar deer, albino blackbuck, blackbuck and barking deer to the Gorewada zoo and rescue centre in Nagpur. "We received two tigresses from the Nagpur zoo early this morning for breeding purposes. The tigresses will be kept in quarantine for 20 days and will be released in their enclosure thereafter," an official said.
