A calf will consume between 100 and 120 gallons per day. It has to gain strength and body size before making the long swim to Alaska. One of the greatest mysteries of the animal kingdom is the whale song. Yes, male humpback whales do the singing here in the breeding grounds. This leads researchers to believe that it is either an attempt to attract females or to ward off other males.
Singers are usually lone animals, staying in one spot.
The song has a very complex structure, similar to a classical music piece. It can be broken down into units, phrases and themes, which make up the entire song. Even more amazing, is that on any given day, all of the male humpbacks in Hawaii will be singing the exact same song, even though the song changes as the season progresses. This years' song will start off where last years' song ended, which provides evidence for an amazing memory capacity considering the whales only sing these songs in their breeding areas. As the season progresses the song will gradually change.
