Southern Hemisphere humpback whales Megaptera novaeangliae migrate from wintering grounds in tropical latitudes to feeding areas in the Antarctic Ocean. It has been hypothesized that the population wintering off eastern South America migrates to feeding grounds near the Antarctic Peninsula (ca. 65 S, 60 W) and/or South Georgia (54 20’S, 36 40’W), but direct evidence to support this has never been presented. Between 19 and 28 October 2003, 11 humpback whales (7 females and 4 males) were instrumented with satellite transmitters off Brazil (ca. 18 30’S, 39 30’W) to investigate their movements and migratory destinations. Mean tracking time for the whales was 39.6 d (range= 5 to 205 d) and mean distance travelled was 1673 km per whale (range= 60 to 7258km). Movements on the wintering ground showed marked individual variation. Departure dates from the Brazilian coast ranged from late October to …
