A record number of southern right whales counted in Península Valdés

On September 9 and 10, in collaboration with Ocean Alliance, ICB undertook the annual aerial photographic survey of southern right whales in Peninsula Valdés. We cataloged 788 whales, the most recorded since we began surveying this population in 1971. The Southern Right Whale Program has been continuously studying and advocating for the conservation of this population of right whales and their habitat in Patagonia for 47 years.

The ICB/Ocean Alliance catalog has images and information about more than 3,200 known individual right whales in Peninsula Valdés. Professor Vicky Rowntree, the program director, explains that “With a good photograph of the head of every whale, we can know who is who in the population study the life history of every individual love the decades.” (Each right whale has a unique  pattern of callosities on its head, and these patterns allow researchers to identify each individual whale.)

“We’re very happy with this year’s results,” says Dr. Mariano Sironi, scientific director of ICB. “We counted 788 whales, including 302 offspring, in Golfo Nuevo and Golfo San Jose. The entire coast between Puerto Madryn and Puerto Pirámides is an almost continuous line of animals. Never in my life have I seen so many whales together in one single day.”
