Another Mystery Mom!

2017 has been a very low calving year for the North Atlantic right whale population. Only 3 calves were documented in the Southeast U.S. calving grounds – the lowest number on record since 2000, when only one calf was sighted. In the intervening years, calving numbers have fluctuated, but on the whole have been lower than right whale researchers would like to see for the recovery of such a critically endangered species.

On April 12, both the Center for Coastal Studies and NEFSC aerial surveys documented a new mom & calf pair for the season, bringing the calf total for 2017 up to 4. While a sighting of new mom & calf pairs outside of the calving grounds is not unheard of, it is not common. So we were very excited Sunday (April 30) when we realized that we had found yet another new mom & calf pair for 2017! I tentatively identified the whale as catalog #1515 while still in the air, but researchers at the New England Aquarium, which houses and manages the North Atlantic right whale catalog, confirmed my identification on Monday morning. The new mom and calf were sighted feeding in the Great South Channel.

#1515 has not been seen since 2009 (also with a calf), so she had been presumed dead by the New England Aquarium. She has been sighted infrequently since 1985 and usually only down on the Southeast U.S. calving grounds, so, much like our other recent mom/calf sighting of 1412, we do not know where she spends the majority of her time. Another mystery mom!
