Humpback whales (Megaptera novaeangliae) utilise warm, shallow, sheltered waters in tropical and subtropical locations for calving. We investigated calving occurring during migration, by examining (1) spatial location where calves were observed (2) depth and SST associated with sightings (3) relative age classification of newborns and (4) GPS Tracks showing movements/direction of travel. We used platforms of opportunity fitted with GPS trackers from 2013 to 2022 for this study. Data on the presence/absence of calves was recorded, and we assigned age classification via known neonate morphology. Newborn calves were observed travelling through Gold Coast waters from June to September. Newborns present here, included the youngest age cohorts Class 1 and slightly older Class 2 cohorts. This ongoing study confirms that 1) parturition occurs regularly during the northern migration, more than 1000 km south of the Great Barrier Reef calving grounds, and 2) newborns are present in the Gold Coast Bay every year. We conclude that some whales utilise warm and shallow waters in southern Queensland to birth calves whilst still on migration. These findings show that the calving range is expanding south where there is no protection in place. Conservation managers need to act to protect these newborns.
