There are two known wintering grounds for humpback whales in the North Atlantic, separated by around 4,000 km of open ocean. For the first time, a whale has been seen moving from one of these North Atlantic winter grounds to the other - and back. Whale number 4756, first seen in the Cape Verde Islands in 2009 and again in 2011, was photographed in the French West Indies in 2012 before returning to the Cape Verde Islands again in 2013. The discovery of this unusual long-distance movement between these discrete breeding areas was the result of a large-scale international collaboration involving Bios.CV and the Irish Whale and Dolphin Group working in the Cape Verde Islands and BREACH and the National Marine Mammal Lab of NOAA in the French West Indies. The re-sighting was made by researchers from the North Atlantic Humpback Whale Catalogue (http://www.coa.edu/nahwc.htm), a central database for identification photographs from across the ocean basin, operated by College of the Atlantic's  Allied Whale.
