Abstract

Nocturnal surveys using auditory cues and night-vision equipment were conducted during the seabird breeding season in 1993 to determine use of inland areas in the Puna District, Hawaii by Newell's Shearwater (Puffinus auricularus newelli). Two hundred sixty Newell's Shearwater auditory or visual detections were made during 275 survey hours from 23 Jul. 1993 - 20 Sep. 1993. Mean detection rates were 1.26 birds/h at Puulena Crater (n = 160 Newell's Shearwater detections), 1.05 birds/h at Heiheiahulu (n = 99) and 0.04 birds/ h at Puu Kaliu (n = 2). Vocalizing peaked between 50 and 90 min after sunset and 4 h before sunrise. Although night-vision equipment was used on most of the seabird surveys, only 4% of seabirds were detected visually. Two road-killed birds collected in Puna in June 1993, and four burrows located in Puulena Crater after the 1994 breeding season, provided additional evidence of breeding.
