Humpback whale mother-calf health assessed using drone tech

University of Hawaiʻi at Mānoa Hawaiʻi Institute of Marine Biology biologists used drone imagery to understand how nursing humpback whale mothers and their calves fare as they cross the Pacific Ocean. Recent declines in North Pacific humpback whale reproduction and survival of calves highlight the need to understand how mother-calf pairs expend energy across their migratory cycle. The study was published in The Journal of Physiology.
