A group of fishermen spotted the eagle and informed wildlife personnel who provided first-aid, officials said, adding that initial examinations showed no signs of any physical injury.
The eagle was about two feet tall and weighing around 6-kg. Its upper body and feathers were rich brown in colour and it had large wings and legs.
Though the Point Calimere Sanctuary attracts thousands of migratory birds from various parts of the globe, it is unusual to see an African Fish Eagle here, officials said.
The African Fish Eagle might have been a surprise visitor to the sanctuary this year, officials said, adding, it is now under the care of the wildlife personnel.
