The flippers are up to a third of the total length of the whale, or about 15 feet long. The flippers are also primarily white throughout the North Atlantic population. The breeding season is from January to March, and occurs on Silver and Navidad Banks, north of the Dominican Republic and Puerto Rico. After mating and calving, the whales swim north and feed in one of five different areas - the Gulf of Maine, the Gulf of St. Lawrence, Newfoundland, Greenland, and Iceland. A Humpback will only feed in one of these areas, and that area is the one its mother brought it to during its first year.
Humpbacks are famous for their songs that they sing.
These songs are structurally similar to the songs of birds. All the males of the same population sing the same song, and that song changes a little each year, as if they are changing a verse. Most commonly, it is believed that these songs are used to attract a female, though other theories exist. One such theory is that the songs are used to establish a territory. Rarely will a male humpback approach another male who is singing.
