George L. Ritchotte Michelle H. Reynolds 1997 <p>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 (<i>Puffinus auricularus newelli</i>). 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 (<i>n</i> = 160 Newell's Shearwater detections), 1.05 birds/h at Heiheiahulu (<i>n</i> = 99) and 0.04 birds/ h at Puu Kaliu (<i>n</i> = 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.</p> application/pdf en Northeastern Bird-Banding Association Evidence of Newell's Shearwater breeding in Puna District, Hawaii article
