The world’s greatest animal migrations - SilverKris

"I learned how dramatic humpback whales are here—launching clear of the ocean, slapping down with thunderous whitewater and filling the air with powerful songs—and that the population has rebounded from under 1,500 after commercial whaling to over 20,000 visitors to the region, as whales swim thousands of kilometres from places like Alaska to Hawaii to give birth, nurse and compete for mates before fasting for much of their stay and returning north to feed; Hawaii is one of the most reliable places to watch them, with peak encounters in February and March." - SilverKris
