Their annual migration can cover up to 6,214 millas (10,000 kilómetros), and attracts thousands of visitors to coastal towns like Byron Bay, Hervey Bay and Eden. The majority of humpbacks migrate back towards the Southern Ocean from September to November, el departamento dijo.
Millar said the whales he has seen this year have been feeding a lot more, possibly due to a shortage of food.
“We are depleting their food source in Antarctica by over fishing,” él dijo.
David M. Baker, Associate Professor at the Swire Institute of Marine Science at the University of Hong Kong, said humans are “competing with (whales) directly for food,” and we are changing where food is available “by altering the global climate.”
“Global fisheries deplete the very things that whales eat, like schooling fish and krill and could severely undermine their recovery,” él dijo. “Climate change is also impairing recovery of some species, including critically endangered right whales in the North Atlantic.”
