The periods for resting and calving shown are estimated peak migration periods. Actual timingof annual migration may vary by as much as 3 weeks from year to year due to food availability inthe Antarctic.
The major calving ground identified is situated in the Kimberly region - Camden Sound.
Humpback whales can also be expected to be encountered outside the shown migratory pathswhich are representative only of the main migratory body during peak season at each area.(ref. Jenner et al 2001)
