Four Jacobin Cuckoo birds were rescued from Mumbai and Thane city on Thursday. These birds are partially migratory and their arrival is an indicator of the onset of monsoon.

The birds were rescued from Mahalaxmi, Pedder Road, Bhandup and Lokmanya Nagar No. 4 in Thane by Plant & Animals Welfare Society-Mumbai (PAWS-Mumbai) and Amma Care Foundation (ACF). "All the four birds were dehydrated. So they were given multivitamin drops and kept under observation," said Veterinarian Dr Rahul Meshram.

PAWS-Mumbai founder Sunish Subramanian told mid-day ACF team and Honorary Wildlife Warden of Mumbai City said, "These birds are an indicator of the onset of monsoon. So, there are high chances of monsoon approaching the city by May end. The doctors announced the birds fit and after informing the Forest Department, they were released."
