They migrate from tropics (breeding areas) to polar or sub-polar regions, reaching the ice edges in both hemispheres (feeding areas); their migrations take them through oceanic zones (Ref. 1394). Maximum depth from Ref. 122827. Feed and breed in coastal waters, often near human population centres, and this helps make them one of the most familiar of the large whales. Feeds on krill and small schooling fish (Ref. 1394). According to a study in the Philippines, Babuyan Islands (121°36’00", 19°18’00) was verified as a breeding ground for this species, and humpback whale songs were recorded during this season. Social groups observed were lone adult, mother-calf pairs, two adults, mother-calf-escort, and a surface active mating group of 3 to 4 individuals (Ref. 77119). Adults length 1600 cm in Ref. 1394. Threats to this species are dynamite and cyanide fishing, pollution, and intrusion of foreign commercial fishing vessels (Ref. 77119), unregulated fishing activities of Taiwanese vessels, i.e. long-line and drift net fishing, and unconfirmed reports of pirate whaling (Ref. 77118). There were nine distinctive themes of humpback whale songs identified wherein 7 of which were common in the Philippines and Hawaii (Ref. 77118).

Associated activities involved cows with young calves escorted by males, aggressive competitive behavior, and singing (Ref. 78067).
