摘要

We present new distributional data from the eastern South Pacific Ocean for the White-headed Petrel (Pterodroma lessonii), Kerguelen Petrel (P. brevirostris), and birds showing characters of the endangered Magenta Petrel (P. magentae). Extrapolation of density for White-headed Petrels suggests a pelagic population of 18,770 birds for the 10( x 5( block of subtropical surface waters between 27-37(S and 80-85(W (August 1995). Two Kerguelen Petrels were noted off Chile at around 40(30'S 74(50'W (August 1995). Three sightings of apparent Magenta Petrels between 28(44'S 72(40'W (March 1992) and 36(24'S 78(02'W (August 1995) are reported to alert observers to the potential occurrence of this species off South America.
