33RD REPORT OF THE CBRC: 2007 RECORDS 
GALAPAGOS/HAWAIIAN PETREL Pte rod rom a phaeopygia/sandwichensis (22, 
1). One was 9.17 n. miles west of Pt. Pinos, MTY, 17 Sep 2005 (ToE; MMe; 2005- 
123A). There is an emerging consensus that the Hawaiian Petrel ( P. sandwichensis ) 
accounts for most or all California records. Force et al. (2007) discussed potential 
identification criteria. The CBRC is currently analyzing all previously accepted Cali- 
fornia records to determine which, if any, can be assigned to the Hawaiian rather 
than the Galapagos or Galapagos/Hawaiian petrels. Adult Hawaiian Petrels with 
satellite transmitters have been tracked making regular foraging forays from Hawaii 
to waters off the west coast of North America, including those off California, during 
the breeding season (D. Ainley pers. comm.). 
STREAKED SHEARWATER Calonectris leucomelas (17, 2). One was 25 n. miles 
west of Pt. Pinos, MTY, 13 Oct 2007 (ToE; RW, 2007-264), and the following day a 
second bird was 2.5 n. miles north of Pt. Pinos (ToEf; DSg; 2007-227). Over half of 
California's Streaked Shearwaters have been found on Monterey Bay, and all records 
fall between 5 Aug and 15 Oct. 
CORY’S SHEARWATER Calonectris diomedea (2, 1). One was 30 n. miles west 
of San Diego, SD, at 32° 43.07' N, 117° 41.83' W on 4 Sep 2007 (DPo ; 2007- 
170). What was presumably the same individual had been observed repeatedly on and 
around the Islas Los Coronados, just south of the international border off Tijuana, Baja 
California, in 2005, 2006 (CBRC 2007), and 2007 (DPo comments in submission), 
but it was noted in U.S. waters only once. As discussed in N. Am. Birds (60:441, 
468), this bird’s underwing pattern is consistent with C. d. borealis. The only Cory’s 
Shearwater previously accepted for California was off Sonoma County on 9 Aug 
2003 (San Miguel and McGrath 2005). 
*MANX SHEARWATER Puffinus puffinus (109, 12). Single Manx Shearwaters 
were seen from Asilomar, MTY, 17 Sep 2006 (BLS; 2007-268), approximately 9 n. 
miles west of Pt. Pinos, MTY, 30 Sep-8 Oct 2006 (DR; MB; 2006-159), southeast of 
Davenport Landing, SCZ, 7 Oct 2006 (MB; 2006-193), from Pt. Pinos, MTY, 5 Oct 
2006 (BLS; 2007-269), off Rincon Pt., SBA/VEN, 2 Mar 2007 (WF; MaS; 2007- 
142), from Pt. Dume, LA, 3 Mar 2007 (KLG; 2007-068), from Pt. Pinos, MTY, 15 
Apr 2007 (BLS; 2007-270), from Pt. Pinos, MTY, 3 Sep 2007 (BLS; 2007-271), 
in Monterey Bay, MTY, 10 Sep 2007 (BLSf; 2007-189), and from Pt. Pinos, MTY, 
28 Dec 2007 (RFo; 2008-001). Two were in the Santa Barbara Channel, VEN/ 
SBA, 23 Sep 2007 (OJt; DVPf; 2007-206). The committee reviews records of this 
species through 2007. 
TOWNSEND’S (NEWELL’S) SHEARWATER Puffin us auricularis newelli (1, 1). 
One at Del Mar, SD, 1 Aug 2007 (DAHf, GMcC, MFPf, MSt, PH; SDNHM #52126; 
2007-156; Unfit et al. 2009; photos also in N. Am. Birds 62:150 and Birding 
40:34) represents a first record for mainland North America. The bird had come 
ashore at night and was dive-bombing men wearing headlamps who were working 
on stabilizing coastal bluffs. One of the workers brought the bird to wildlife rehabilita- 
tors, who identified it initially as a Manx Shearwater. When the bird was brought to 
the SDNHM, however, Unfit noted that the undertail coverts were white basally but 
black distally and identified the bird as a Newell’s Shearwater (Unitt et al. 2009). The 
identification of Townsend’s (P. a. auricularis), Newell’s, and Manx Shearwaters was 
addressed by Howell et al. (1994). The bird eventually died at Project Wildlife and is 
now a specimen at SDNHM. Newell’s breeds in the Hawaiian Islands, Townsend’s on 
the Revillagigedo Islands off west Mexico (AOU 1998). 
TRISTRAM’S STORM-PETREL Oceanodroma tristrami (1, 1). One photo- 
graphed on Southeast Farallon I., SF, 22 Apr 2006 (PWf; 2007-162; Figure 1; 
photos also in Birding 40:35) represents a species new to North America. It was 
captured during nocturnal banding of storm-petrels. The biologists handling it initially
