The southern right whale was given its name because tragically, it was the "right" whale for whaling
The southern right whale was given its name because tragically, it was the "right" whale for whaling. The animals tended to swim close to shore, making them easy marks for whalers who hunted them to the brink of extinction.。
Thanks to drones, researchers are helping the southern right whale make a comeback while keeping an eye on the effects of climate change.。

"Although the humpback was hunted almost as much, the humpbacks are 10 times as many now as the southern right whale," he said. "They are still endangered. There are still populations in the North Atlantic where they are critically endangered."。
When the whales visit Australia, they typically breed and aggregate along the south coast of the country from late May to late October. That gives scientists the opportunity to use drones to monitor their health. 。

The team fly DJI Inspire 1 Pro drones off the cliffs of the Great Australian Bight with the permission of the Aboriginal Lands Trust, allowing them to minimise disturbance to the animals while getting high resolution images and measurements.。
"When the whales leave, the females look quite emaciated," he said. "There is so much energy being transferred between the female and the calves, especially when they're not feeding." During this time, the mother whales rely entirely on their fat stores.。

Ultimately, the team hope to discover how climate change will affect the whales. For example, how krill production in their Antarctic feeding ground -- the abundance of which will likely be impacted by the rise in sea temperature and receding sea ice -- will affect their condition once they arrive in Australia.。
"We can also compare our population to other populations to see if the Australian population is doing better," he added. 。
