ABSTRACT

We compared the catalogues of photo-identified humpback whales from four 
research groups working in Southern Hemisphere breeding areas collected 
between 1996 and 2010. The entire dataset included individuals: 1470 from 
Ecuador 96 from Peru and 168 from America Samoa (Breeding Stock E-3). Two 
matches were found between Ecuador and Peru catalogs, all of them were 
inter-year re-sightings. Our data confirms that the breeding area of the 
Stock G extends approximately 700 km to south of Ecuador. Our study suggests 
and adds further evidence the northern Peru coastal area may be considered 
as the southern limit of the breeding area for BS-G. In addition, our study 
highlights the importance of continuing the exchange of catalogs with other 
adjacent and on/adjacent, which would have implications for management and 
conservation.
