24 FEBRUARY 1998. CHILE AND PERU: SEABIRDS

"Noam Shany of Cardiff, California, recently reported to me some seabird observations he made while aboard the Scripps Institution of Oceanography research vessel Melville from 31 December through 15 January 1998, when it was conducting geophysical research between Callao, Peru and Valparaiso, Chile, along the Peru-Chile Trench. He said they sighted Waved Albatross (Diomedea irrorata) further south than expected-- 33 degrees South, which is 14 degrees further south than the southern boundary of its range off Arica in northern Chile. Also, Swallow-tailed Gulls (Larus furcatus) were seen in large numbers as far south as Valparaiso. This is within their range but sightings considered rare off Chile from Arica south to Algarrobo (Araya & Chester). Peruvian Terns (Sterna lorata), usually found inshore and not generally considered an open-ocean pelagic species (see Harrison, Parker et al, Araya and Chester), were common as far as 70 km offshore where they were seen consistently perched on floating driftwood. Also seen were large numbers of Wedge-rumped Storm Petrels (Oceanodroma tethys) and an unusual occurrence of the Atlantic species Manx shearwater (Puffinus puffinus). Numerous dolphinfish, (Coryphaena hippurus), were landed during the trip and stomach contents examined of 41 individuals. Of these, 40 stomachs were empty, and the only one that contained food had only a few crab larvae. Seabirds sighted on the trip included: Waved, Salvin's(Shy), Grey-headed, Buller's, Wandering, and Black-browed Albatrosses; White-chinned, Kermadec, de Fellipe's, Stejneger's, Cape, Gray, and Juan Fernandez petrels; Ringed(Hornby's), Markham's (sooty), Elliot's(white vented), Wedge- rumped, Band-rumped, and Wilson's Storm Petrels; Sooty, Pink-footed, Bullers, and Manx shearwaters; Long-tailed, Parasitic, and Pomarine Jaegers; South Polar and Chilean Skuas; Grey, Band-tailed, Sabines, Kelp, Swallowtail, Franklin, and Laughing Gulls; Humboldt Penguin; Masked, Peruvian, and Blue-footed Boobies; Red-billed and Red-tailed Tropicbird; Peruvian Pelican; Inca, Elegant, Common, South American, Peruvian, and Sooty Terns; and Red- legged, Guanay, and Neotropic Cormorant.-- Susan Smith <Susan.Smith@noaa.gov>
