33RD REPORT OF THE CBRC: 2007 RECORDS 
Figure 1. This Tristram’s Storm-Petrel ( Oceanodroma tristrami) captured on 
Southeast Farallon Island on 22 Apr 2006 was initially identified as a Black Storm- 
Petrel (O. melania). Subsequent review of the photos by Steve N. G. Howell, Peter 
Pyle, and Richard Stallcup indicated that the bird was definitely not a Black Storm- 
Petrel and likely a Tristram’s Storm Petrel. Extensive comments on the record, 
including measurements of specimens, were submitted by Howell and Pyle. In 
particular, the bird’s large size, with a wing chord (191 mm) substantially longer than 
that of any similar species, confirmed the identification. 
Photo by Russ Bradley 
thought the bird was likely a Black Storm-Petrel (O. melania), but Warzybok et al. 
(2008) later identified it as a Tristram’s Storm-Petrel. The comments and detailed 
analysis by Warzybok et al. (2008) and other experts consulted, especially Pyle, were 
added to the record. This species breeds on the northwestern Hawaiian Islands and 
the Japanese islands of Torishima (Izu Is.) and Kita-ioto or Kita Iwo (Volcano Is.) and 
ranges at sea from the Hawaiian Islands to Japanese waters (AOU 1998). There are 
no other records of this species in the eastern Pacific (P. Pyle pers. comm.). 
RED-TAILED TROPICBIRD Phaethon rubricauda (28, 1). One was 158 n. miles 
southwest of San Nicolas Island, VEN, 28 Sep 2005 (TSt; 2005-183). It was one of 
42 Red-tailed Tropicbirds observed on a Southwest Fishery Science Center research 
cruise in the northeastern Pacific in 2005. Seven of the 42 were in California waters 
(P. Pyle pers. comm.), and the CBRC has accepted four of these (Iliff et al. 2007). 
MASKED BOOBY Sula dactylatra (14, 1). A subadult came aboard the sport- 
fishing boat MV Victory between Santa Catalina I. and Long Beach, LA, 29 Sep
