So all right, it was a langur. As the Calcutta Telegraph repeorts:

In the thick of political manoeuvres, a langur offered a welcome break to the chief minister on Tuesday while she was inaugurating a Jagaddhatri puja in Hooghly’s Chandernagore. As a furry shape emerged, Mamata Banerjee stopped her speech midway and asked: “Eta abaar kotha theke elo? Eta abaar kotha theke elo (From where did this come? From where did this come)?” The langur ran in front of her and behaved itself by squatting in a corner of the dais. “Ami pashu-pakhi khub bhalobasi. Keu kichhu korben na (I love animals and birds. No one should disturb it),” she said. The chief minister also asked the members of her security team to arrange biscuits. Yes, the langur did sit through the speech, though it switched to another part of the pandal. Pictures by Pradip Sanyal

The video, though, offers another aspect of the (under-reported?) story. Dear leader, clearly is well-versed in appropriate mantras for all occasions.
