Even information as to whether identified individuals are visitors or residents of the region is unknown. Here, we report on opportunistically collected observations in this region from 2001 through 2012. Killer whales were observed on 119 separate occasions in group sizes ranging from one to groups of over 50 individuals. We also describe observed behaviour and present a first catalogue of individuals in Chilean Patagonia. We identified 49 individuals, only seven of which were sighted more than once. 2013 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47926382005 en http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.1 Vol.48 |
