The birds, kept in two iron cages, were rescued by the Border Security Force (BSF) jawans during an operation on Tuesday night at Shah Para village in Tentulberia area of the district, the statement said.
The traffickers, who had smuggled the birds into India, however, were nowhere to be found.
The exotic birds 11 Chattering lory, 13 Red-and-blue lory, eight each Black-capped lory, Violet-necked lory and Black lory and six Brown lory were handed over to authorities of Alipore Zoological Garden.
Zoo Director Ashis Samanta told PTI the birds would be under the observation of veterinarians for about a month since they were kept in "not so ideal conditions".
