ABSTRACT: The Spectacled Petrel Procellaria conspicillata is endemic to Inaccessible Island, in the Tristan da Cunha group (central South Atlantic). The species is considered an occasional visitor to Argentina and t here are few records of the species in national waters. On 13 February 2014, two birds were observed (and photographed) 89 nautical miles southeast off Buenos Aires Province at 38°55'S, 56°00'W. This recor d represents the second documented record of Spectacled Petrel for Argentina. KEY-WORDS: Occurrence, Argentina, Buenos Aires Province, Continental shelf, Spectacled Petrel. The Spectacled Petrel Procellaria conspicillata is a breeding all undocumented records. In recent years, Ginsburg & endemic of Inaccessible Island, in the Tristan da Cunha DeWitt (2013) photographically documented the species group (Ryan 1998, Ryan & Moloney 2000, Ryan et al.
