Sex‐related site fidelity of humpback whales ( Megaptera novaeangliae) to the Fueguian Archipelago feeding area, Chile
Abstract We investigated sex‐related site fidelity by humpback whales to the Fueguian Archipelago, a new feeding area in the eastern South Pacific, by examining the resighting histories of 45 males and 39 females recorded from 2003 to 2012. Results indicated an overall annual return to the feeding a...
