The calf has been rescued by the FD and is undergoing treatment at the Balle Elephant Camp. It is a male calf and with treatment should ( hopefully ) make a full recovery.Physical health seems ok , needs rest and shelter.
The most surprising thing about the whole episode is the apparent abandonment of the calf by the Mother and Aunt. When first spotted they were very protective and would charge the boat if we tried to get too close. After a week they would leave the calf and swim across the river to feed. Last few days we always saw the calf alone with the Mother and Aunt grazing on the opposite bank.
This is full frame at 70 mm , the FD would not have been able to rescue the calf if the Mother and Aunt were close by.
