Evidence for a widely expanded humpback whale calving range along the Western Australian coast
The recognized calving grounds of humpback whales ( Megaptera novaeangliae ) that breed along the Western Australian coast (Breeding Stock D) extend along the Kimberley coast between Camden Sound and Broome (1518S). However, there are reports of neonates further south, suggesting that the calving ar...

The recognized calving grounds of humpback whales ( Megaptera novaeangliae ) that breed along the Western Australian coast (Breeding Stock D) extend along the Kimberley coast between Camden Sound and Broome (1518S). However, there are reports of neonates further south, suggesting that the calving areas may be poorly defined. During aerial photogrammetric research in 2013 and 2015, we sighted large numbers of humpback whale calves along North West Cape (2147′2243′S). We estimated the minimum relative calf abundance to be 463603 in 2013 and 557725 in 2015. We categorized the calves as either neonate or post neonate according to their color and size. The majority of calves sighted in both years (85% in 2013; 94% in 2015) were neonates.
