Abstract

PETRACCI, Pablo F et al. Update on the status of South American Sea Lion (Otaria flavescens) colony from Trinidad Island, Bahía Blanca estuary, Argentina. Mastozool. neotrop. [online]. 2010, vol.17, n.1, pp.175-182. ISSN 0327-9383.

The South American Sea Lion (Otaria flavescens) is distributed along the Argentinean coast, from Mar del Plata to Tierra del Fuego and Malvinas Islands, with 70 reporte colonies. In Buenos Aires there is one breeding colony in Banco Culebra and three non reproductive settlements in Mar del Plata, Quequén and Trinidad Island. The latter was reported for the first time in 1952, since then no further records were published about its current status and the information cited by many authors is confusing. Here we provide new observations about the population size of this colony from 1990. Seal counts ranged between 0-150 males and sub-adults depending on the season.

Keywords : Buenos Aires; Otaria flavescens; South American Sea Lion.
