The origin of the eagles and eagles fishing, probably in the general area in the Bay of Bengal. During the Eocene / Oligocene, as the Indian subcontinent collided with Eurasia, slowly, this vast expanse of relatively shallow ocean, the initial divergence of March eagle seems to have resulted in four tropical (and subtropical Southern Hemisphere) species across the Indian Ocean today.
