Any great journey starts out with a little trepidation, think back to your first day of school, walking out into the big wide world (or playground) and then looking back to see your guardian eagerly watching and willing you to keep going. These first steps are always the hardest, and as one of the the largest mammals on the earth there's no exception. Scientifically classified as one of the "big-winged" (Megaptera) species, the Humpback Whale make their annual move north from the warm Hawaiian Island waters from March onwards. Seeking fresh food and cooler temperatures, these magnificent giants will travel through currents so challenging that only perseverance will see them through. And as a newborn, the first ocean crossing will be something to remember. After approximately four months of not eating and living off her own blubber, it's not just the cow's instinct which is telling her that it’s time to move on. With calf in tow, she sets off. From the low-latitude breeding grounds, they will travel at 3-9 mph (5-15kph) or as fast as the calf can swim. Sometimes this can take up to three months, but at 1,000miles per month, at this stage they can’t afford to waste a moment of their time.
